One World, One Sun, One Grid: Is it possible?

With war clouds hovering around several Nations in the world, will it be ever possible for us to see a One World One community?

One basic need of the humans – Energy – seems to have the potential to bring and connect people of the world to come together cutting across geographical barriers.

September 8, 2020. The International Solar Alliance (ISA) organised a virtual World Solar Technology Summit.

India’s Prime Minister Narendra Modi was earlier expected to deliver the inaugural address but could not do so because of some other engagements. His message was read out by the New and Renewable Energy Minister R K Singh.

One World

The PM Modi expressed his visions on humanity and the global use of clean energy supplies across nations. He mentioned the idea of ‘One World, One Sun, One Grid’. The Prime Minister also mentioned that ISA is part of this project which can bring transformational benefits for the entire humanity.

The PM Modi made it clear that his government wants to take solar energy to all villages of India and replace fossil fuels with this clean source in agriculture.

India’s existing clean energy capacity is 134 GW. It will be scaled up to 220 GW by 2022.

The PM Modi exuded confidence that India will reduce energy tariffs further through technological advancements. A further reduction in the cost will provide a major boost to the use and expansion of renewable energy.

Five public sector undertakings (PSUs) – Oil and Natural Gas Corporation Limited (ONGC), Indian Oil Corporation Limited (IOCL), Bharat Petroleum Corporation Limited (BPCL), Hindustan Petroleum Corporation Limited (HPCL) and GAIL (India) Limited – under the Petroleum and Natural Gas Ministry may join ISA’s Coalition for Sustainable Climate Action (ISA-CSCA) as corporate partners.

Oil Minister Dharmendra Pradhan said the PSUs will be active contributors to ISA’s Corpus Fund.

Pradhan stated that the government is actively encouraging the industry, oil and gas companies in particular, to become participants in this transition to solar energy. The mission of solarising nearly 50 per cent of fuel stations owned by public sector oil companies in the next five years is in progress. The oil and gas companies are deploying solar panels across the value chain of their operations.   The current installed solar power capacity is 270 MW. An additional 60 MW solar capacity will be added in one year.

Renewable Energy Shows the Way to Make Money

Renewable energy stocks have teased investors with their promise for years. On the one hand, it’s easy to dream on the sector’s growth potential given the need to transition the global economy away from its current fossil fuel-based approach to a more sustainable one. According to one estimate, the world’s developed economies need to invest a staggering $10 trillion in the coming years to make the switch. However, despite all the investments in the sector, most clean energy stocks have significantly underperformed the market over the years.

Two factors have driven this underperformance: intense competition and weak financial profiles. With so many companies focused on doing the same thing, the industry has fought against itself for growth opportunities, which has hurt investment returns. Meanwhile, most clean energy companies focused on growing as fast as they could despite the lacklustre returns. As a result, many stretched themselves too thin, putting pressure on their balance sheets and stock prices and burning investors in the process.

A small group of renewable energy companies, however, have thrived despite the sector’s issues. That’s allowed them to consistently create value for their investors over the years.

One of the defining characteristics of these outperformers is that they aim to grow the value of their company, not just its size. Thus, those who want to invest in renewable energy stocks should seek out companies focused on this pursuit.

While many companies want to profit from the renewable energy sector’s growth potential, far fewer have a visible plan aimed first at increasing shareholder value. That makes them stand out as the top investment options in the space.

The best renewable energy stocks to buy

Given the outsize growth potential of the renewable energy sector, most companies focused on the industry should be able to increase their revenue in the coming years. Far fewer will be able to expand their profitability, especially on a per-share basis due to competition and financial concerns.

The following four companies, however, have a plan to grow their earnings per share, which increases the probability that they’ll produce market-beating returns for their investors:

Here’s a closer look at what makes them the top renewable stocks to buy for the long term.

Brookfield Renewable Partners: Focused on creating value

Brookfield Renewable Partners is one of the largest renewable energy companies in the world. It boasts a globally diversified, multi-technology renewable power platform that includes:

  • Hydroelectric generating facilities
  • Wind farms
  • Utility-scale solar projects
  • Distributed generation assets (i.e., the energy produced near where it’s used, such as rooftop solar)
  • Energy storage

As of August 2019, hydro made up 75% of the company’s portfolio followed by wind at 21% and solar at 4%.

Brookfield makes money by selling the bulk of the renewable energy it generates to customers like utilities under long-term, fixed-rate power purchase agreements (PPAs). These contracts provide the company with predictable cash flow while insulating it from volatile power prices. The company typically distributes the bulk of its cash flow (80% on average) back to investors via a high-yield dividend. It reinvests the rest into the building or buying additional renewable energy-generating assets.

The company has a high hurdle rate for new investments, targeting opportunities that will generate 12% to 15% total returns over the long-term. It’s able to achieve this goal by investing on a value basis, leveraging its operational expertise, and remaining disciplined. Brookfield typically targets opportunities where it can buy underperforming assets and turn them around by improving their operations and cost structure.

Brookfield’s focus on improving is evident in its long-term outlook. The company aims to grow its cash flow per share at a 6% to 11% annual rate through at least 2022, which should allow it to increase its dividend at a 5% to 9% yearly pace. One factor powering that plan is the company’s ability to improve the profitability of its existing assets. That factor alone should supply it with half of its cash flow growth over that time frame. The other half will come from building new renewable projects that meet the high bar it’s set for investment return.

The company’s value-focused approach has paid big dividends over the years. In the two decades since its inception through mid-2019, Brookfield has generated a 16% annualized total return. For comparison’s sake, the S&P 500 only delivered a 7% total annualized return over that time frame.

If there’s one concern with Brookfield Renewable, it’s that some of its operations reside in economically sensitive countries like Brazil. The company takes steps to reduce its risks in those regions by using hedging contracts to lock in currency rates and power prices. However, a prolonged economic slump could negatively impact its earnings and weigh on its market value.

While Brookfield Renewable Partners has battled its share of ups and downs over the years, it has proven that slow and steady can win the race. The company has consistently grown its cash flow by investing in opportunities that meet its strict criteria. That’s enabled it to routinely increase its distribution to investors, allowing them to collect a growing income stream. That trend isn’t showing any signs of stopping, which is why Brookfield Renewable is a great clean energy stock to buy for the long term.

First Solar: A premier solar panel maker

First Solar is a solar panel manufacturer. However, it differentiates itself from most competitors in two ways.

First, the company develops and manufactures thin-film modules that use cadmium telluride as a semiconductor instead of the conventional crystalline silicon technology. While these panels aren’t as efficient in converting the sun’s rays into electricity, they have a lower cost per watt.

First Solar offsets some of the efficiency loss by making larger panels compared to those produced by its competitors. On the one hand, this makes them less suitable for residential rooftops. However, they’re ideal for utility-scale projects that connect to the grid since it doesn’t have to install as many panels per project to produce the same amount of power. Consequently, First Solar has developed and operates many of the world’s largest grid-connected solar power plants.

Secondly, First Solar’s history of innovation sets it apart from the competition. While many rivals focus on manufacturing low-cost silicon-based panels, First Solar invests industry-leading amounts of capital into developing more efficient thin-film solar panels. Its more-innovative products carry higher margins, which enables it to make more money. In 2018, it launched its latest innovative product, the Series 6 module, which is even more efficient than the Series 4 panel it’s replacing. The company decided to completely skip the launch of the Series 5 module and accelerate the migration to the larger Series 6 because it was more cost-competitive with rival panels.

The company invested more than $1 billion into Series 6, which included research and development (R&D) costs, as well as building out manufacturing capacity in the U.S. and Asia. That investment should start paying off in 2019. Its earnings are on track to surge more than 80% year over year at the midpoint of its forecast. That accelerated earnings-per-share growth should continue in the years that follow as it cashes in on its investment in the Series 6 module.

Despite its massive investments in R&D, First Solar has managed to maintain one of the best balance sheets in the solar sector. The company expects to end 2019 with between $1.7 billion and $1.9 billion of net cash. That cash-rich balance sheet gives it an unmatched competitive advantage versus its financially weaker peers, most of which are weighed down by a mountain of expansion-fueled debt. First Solar, on the other hand, has the unparalleled financial flexibility to continue investing to increase its capacity as well as on its next innovation.

While First Solar is a top-tier solar panel manufacturer, it operates in a highly competitive industry. Because of that, the company needs to continue pouring money into R&D so that it doesn’t lose its competitive edge. If it fails to innovate, it might start falling behind. It also needs to battle against rising costs and falling panel prices by keeping its expenses at bay to protect its profit margins.

In spite of those risks, First Solar appears well-positioned to prosper thanks to its strong balance sheet, healthy earnings growth prospects, and a history of innovation. That combination should give it the power to generate market-beating returns in the coming years.

NextEra Energy: A history of outperformance and a plan to continue

NextEra Energy is a clean energy-focused company. It operates two distinct businesses:

  • Government-regulated utilities (Florida Power & Light and Gulf Power)
  • A competitive energy business (NextEra Energy Resources) that generates electricity and sells it to third parties under long-term PPAs

NextEra Energy’s affiliates combine to generate more electricity from the wind and sun than any other company in the world. In addition, it’s a leader in battery storage.

The company’s regulated utilities produce energy from a variety of sources (including natural gas, nuclear, coal, and solar) and distribute it as well as natural gas to customers. These businesses generate relatively predictable income since regulatory bodies set rates and demand tends to increase at a steady pace as Florida’s population and economy expand.

NextEra’s energy resources segment owns an extensive portfolio of power-generating facilities including wind, solar, nuclear, natural gas, and oil. In addition to that, the company operates a meaningful natural gas pipeline business. The company sells the power it produces under long-term PPAs and leases capacity on its gas pipelines via long-term contracts. Those agreements enable NextEra to churn out predictable cash flow.

NextEra has a long history of creating value for investors by consistently growing its earnings and dividend. From 2003 through 2018, the company increased its adjusted earnings per share at a 7.8% compounded annual rate while boosting the shareholder payout at a 9.1% yearly pace. That consistent growth has enabled the utility to generate market-crushing returns. In the decade from 2008 through 2018, it produced a 380% total return, which outpaced not only its utility peers (170% total return over that time frame) but also the S&P 500 (243%).

The utility firmly believes it can continue to grow earnings at a healthy clip in the coming years. Powering NextEra’s forecast is a massive backlog of expansion projects. The company expects to invest from $23 billion to $25 billion in Florida Power & Light from 2019 to 2022 and another $2.9 billion to $3.3 billion in Gulf Power on a variety of projects, including new solar capacity. It has lined up $25 billion to $28 billion of investments at energy resources, mainly on renewables. The company currently expects to build 11.7 GW of renewable projects over that time frame. That would boost its industry-leading portfolio, which consisted of 18 GW of wind and solar capacity in August 2019.

While NextEra Energy has a strong balance sheet, it will be investing a significant amount of money in expanding its operations over the next several years. At the same time, it plans to continue increasing its above-average dividend. That will be a tough balancing act. The company will likely need to secure substantial amounts of outside funding to bridge the gap, including selling assets to its MLP NextEra Energy Partners. If it runs into trouble obtaining financing, then it might not grow its earnings at as fast as it expects.

The company, however, does have a long history of being able to finance its growth while increasing the dividend. That’s why it firmly believes it can deliver on its growth plan. That outlook would see earnings per share expand at a 6% to 8% compound annual rate through at least 2022 from 2018’s base. The company also expects to receive an additional earnings boost in 2020 and 2021 from the integration of its acquisition of Gulf Power as its cost-saving initiatives start paying off. That would enable NextEra to continue to increase its dividend at a healthy rate during that period, which should give it the power to keep producing market-beating total returns.

TerraForm Power: Value creators are now in charge

TerraForm Power focuses on owning and operating wind and solar power assets in North America and Western Europe. As of the middle of 2019, 64% of the company’s portfolio consisted of wind assets, while the rest was solar.

Like Brookfield Renewable, TerraForm Power makes money by selling the electricity it generates to end-users under long-term PPAs. Those contracts provide it with predictable cash flow, most of which (its payout ratio typically ranges between 80% to 85%) it returns to investors via a high-yield dividend. The company reinvests the remaining cash flow on high-return projects that expand its renewable power generating capacity. For example, it has three projects underway to upgrade some of its existing wind farms by installing newer, larger turbines that it hopes to complete by 2021. These investments would boost the power output at those locations by 25% to 30% at a 40% discount on the cost of building new wind farms. That enables TerraForm to boost its per-share earnings without making a substantial investment.

Aside from a similar business model, another reason TerraForm Power has so much in common with Brookfield Renewable is that they have the same parent in Brookfield Asset Management (NYSE:BAM). Brookfield Asset and Brookfield Renewable joined forces in 2017 to take control of TerraForm Power after its former parent went bankrupt. They’ve since helped TerraForm get its financials back on solid ground while improving its operational focus and reducing costs. These factors have helped boost the profitability of TerraForm’s legacy assets while giving it the financial flexibility to acquire new ones.

TerraForm made two major acquisitions in the first two years since Brookfield took control. Those transactions will provide the company with enough power to increase its dividend at a 5% to 8% annual rate through 2022. One of the main drivers of this growth is TerraForm’s ability to improve the profitability of the assets it acquired by reducing costs.

Like many renewable energy companies, TerraForm Power has struggled to create value for investors in the past. Before Brookfield took over, the company’s total return was a negative 50%. Those value-destroying ways, however, have changed since it began implementing Brookfield’s game plan. In the first 22 months after Brookfield took control, TerraForm generated a nearly 44% total return, which obliterated the S&P 500’s 17% total return over that timeframe.

While the Brookfield-led turnaround has been highly successful, TerraForm Power is still dealing with some of the lingering effects of its former parent. The biggest concern is its balance sheet, which remains loaded with debt. Because of that, the company’s credit rating is below investment grade, which makes it harder and more expensive to borrow money. The company is working to address that issue by selling non-core assets and boosting its profitability.

As TerraForm’s financial profile improves, it will enhance the company’s ability to grow cash flow per share. That will increase the probability of achieving its dividend growth plan. Its new focus on creating shareholder value should give it the power to continue to outperform.

Focused on growing what matters most to investors

Regardless of its promise, the renewable energy sector has burned investors in the past due to intense competition and aggressive growth. Many companies have struggled to make money, with some having to declare bankruptcy.

The sector, however, is beginning to learn from those growing pains as well as from the companies that succeeded where others failed. Because of that, the renewable energy industry appears to have brighter days ahead, especially as climate change concerns heat up. While many companies could prosper in the coming years, these four have a long-term growth strategy aimed at increasing their earnings per share. That improves the probability that they can create value for shareholders, which makes them the best stocks in the sector to buy in the renewable energy sector.

WEC Energy Acknowledges Need To Change

Image Source: WEC Energy Group Inc – IR Presentation

By Callum Turcan

WEC Energy Group Inc. (WEC) is a regulated electric and natural gas utility based in Milwaukee, Wisconsin, that serves 4.5 million customers across the Midwest primarily in the following states; Wisconsin, Illinois, Michigan and Minnesota. That includes power generation, transmission, and natural gas delivery operations that are supported by its natural gas storage assets. Shares of WEC yield 2.6% on a forward-looking basis as of this writing. We aren’t interested in WEC Energy given its heavy reliance on coal-fired power plants at a time when natural gas and renewables (aided by government subsidies) are increasingly dominating the power generation landscape. Furthermore, we caution that domestic utilities that are overly reliant on coal-fired power plants will likely face major regulatory and environment hurdles in the medium-term, especially if the Clean Power Plan or some version of it is reinstated and that plan is enforced with the teeth of federal regulators.

Dividend Commentary

In 2018, WEC Energy generated $0.3 billion in free cash flow (defined as net operating cash flow less capital expenditures) while spending $0.7 billion on dividend payments. Debt issuance was used to cover the gap. We like the stability of WEC Energy’s free cash flows over the past three full fiscal years, which averaged $0.4 billion during this period, but caution the firm needs to maintain access to capital markets to cover both its dividend commitments and growth trajectory. We would like to note that if WEC Energy didn’t pursue significant growth activities its free cash flows would likely be much stronger (as its capital expenditures would be materially lower).

However, the company is seeking growth opportunities as many are available and capital markets are very willing to keep lending WEC Energy more money. We’ll cover that growth runway in greater detail in a moment. Having investment grade credit ratings and positive free cash flows make this process significantly easier.

WEC Energy prefers to use debt issuance, and not equity issuance, to fund its growth trajectory and please note the company has historically repurchased a marginal amount of its stock each year to offset dilution (from activities like stock-based compensation). At the end of June 30, 2019, WEC Energy had a net debt load of $11.9 billion (inclusive of short-term debt). Lower interest rates in the US will make refinancing activities significantly easier, and should lower WEC Energy’s cost of debt.

Shifting Away from Coal

As you can see in the graphic below, 48% of WEC Energy’s rated electric generation capacity was represented by its coal-fired power plants at the end of last year. Most of the remainder is made up by older less economical peaker plants (fueled by oil and natural gas) which are turned online during times of elevated demand (cold winters, hot summers, unplanned outages at baseload facilities). Only a quarter of WEC Energy’s rated power generation capacity is represented by more modern (and most importantly, very economical) combined cycle natural gas-fired power plants. Please note that natural gas prices in America have been very low for some time and are likely to remain subdued going forward given the abundance of domestic and Canadian gas supplies. Renewables made up just a tiny portion of WEC Energy’s rated power generation capacity at the end of 2018.

WEC Energy is making major investments to change this picture, which we can appreciate. In its 2018 Annual Report, the company notes it planned to retire 1,800 MW of coal-fired power generation capacity by 2020. Last year, the firm retired 1,500 MW of coal-fired power generation capacity as part of that effort. This year, WEC Energy retired the coal-fired Presque Isle power plant. That capacity is being replaced with natural gas-fired generation capacity at WEC Energy’s Upper Michigan Energy Resources (“UMERC”) subsidiary. UMERC turned two new gas-fired power plants online this year with a combined 180 MW of power generating capacity. WEC Energy is also investing in a handful of renewable energy projects as well.

Betting Big on Wind

By the end of 2019, WEC Energy expects that its Coyote Ridge Wind Farm project in South Dakota will be completed. WEC Energy has already signed an offtake agreement with Alphabet Inc.’s (GOOG) (GOOGL) Google Energy to buy 100% of that power generation for 12 years. The utility mentions that over three dozen wind turbines made by General Electric Company (GE) will be used to create the wind farm, which is expected to have almost 100 MW of power generation capacity.

Keep in mind that Google Energy is likely to need power indefinitely, so there are reasons to believe that its 12-year deal with WEC Energy could be extended given that Alphabet wants to source as much of its electricity consumption as possible from renewable energy. Avangrid Renewables, a subsidiary of Avangrid Inc. (AGR), is developing the wind farm and will be the operator once completed. WEC Energy acquired an 80% stake in this development in early-January 2019 for $145 million. That asset is expected to qualify for the federal production tax credit.

The Coyote Ridge Wind Farm project is one of many renewable energy endeavors WEC Energy is pursuing. WEC Energy increased its stake in the 132 MW Bishop Hill III wind farm in Illinois to 90% from 80% last year, and at the start of 2019, WEC Energy acquired an 80% stake in the ~203 WM Upstream Wind Energy Center in Nebraska. Both of those power plant facilities are now operational. The revenue streams generated through the power produced and sold from these assets are secured by long-term contracts.

On September 3, 2019, WEC Energy agreed to acquire an 80% stake in the 330 MW Thunderbird Wind Energy Center in Nebraska for $338 million. By the end of 2020, commercial operations are expected to commence. 108 GE wind turbines are expected to be use to develop this wind farm, and the venture is supported by an offtake agreement for 100% of the energy produced.

Management is serious about bulking up WEC Energy’s renewable asset base, with the production tax credit meaningfully enhancing the expected returns on these developments. Please note that as things stand today, the production tax credit is expected to phase out soon, which is why it’s very important that the developers WEC Energy is working with bring these wind farms online on-time.

When it comes to solar, WEC Energy teamed up with a subsidiary of MGE Energy Inc. (MGEE) to bring an additional 150 MW of power generation capacity at the Badger Hollow Solar Farm in Wisconsin online. That’s on top of the 150 MW of power generation capacity already planned at the site. The expansion was announced on August 1, and the joint venture expects to begin commercial operations by the end of 2020 from the development’s first phase. The second phase is forecasted to start commercial operations a year later in 2021. At peak capacity, the Badger Hollow Solar Farm will add 300 MW of gross renewable power generation capacity to WEC Energy’s asset base.

Concluding Thoughts

WEC Energy has accepted it needs to shift its power generation operations away from coal (which faces major medium- and long-term regulatory and environmental hurdles) and towards cleaner options. Natural gas represents America’s bridge fuel as the country slowly shifts towards a world where renewables will no longer play second fiddle to coal, natural gas, nuclear, or hydro-conventional sources of electricity generation. That being said, we still aren’t interested in shares of WEC here as we see better income growth opportunities out there.

Stanford researchers make unique wind energy farm discovery

A new study conducted by researchers from Stanford could be good news for wind farms.

The researchers have discovered that a wind energy farm can generate more electricity if its turbines are angled slightly away from the wind, instead of pointing directly into it.

This method of generating wind is called wake steering.

Unlike solitary wind turbines, which generate the most power when they are pointing directly into the wind, wind energy farms – spaces filled with rows of tightly packed turbines – struggle to function at their maximum potential when positioned this way.

The reason is that when these tightly packed turbines face the wind head-on, wakes from upstream generators can interfere with those positioned downstream. The wake from a wind turbine lowers the output of those behind it in a similar way to how a speedboat can be slowed by choppy water from a boat sailing in front of it.

Positioning turbines away from an oncoming wind is called wake steering. The newly published Stanford wind energy farm study found that wake-steering can lower the interference and improve both the quality and quantity of power from these farms as well as has the potential to lower operating costs.

“To meet global targets for renewable energy generation, we need to find ways to generate a lot more energy from existing wind farms,” said John Dabiri, professor of civil and environmental engineering and of mechanical engineering, and senior author of the paper, reports Stanford.edu.

“The traditional focus has been on the performance of individual turbines in a wind farm, but we need to instead start thinking about the farm as a whole, and not just as the sum of its parts.”

The wind energy farm study was conducted on a working wind farm.

Before testing their theory, the Stanford group came up with a quicker way to calculate the optimal misalignment angles for turbines. They tested these calculations on a wind turbine farms in Alberta, Canada in collaboration with the farm’s operator, TransAlta Renewables.

Through their study, the researchers found that the overall power output of the farm boosted by up to 47% in low wind speeds, depending on how the turbines were angled, and by 7 to 13% in average wind speeds. Additionally, wake steering reduced the ebbs and flows of energy that are typically challenging with wind electricity generation.

“Through wake steering, the front turbine produced less power as we expected. But we found that because of decreased wake effects, the downstream turbines generated significantly more power,” said Michael Howland, a mechanical engineering PhD student and lead author on the study.

The Stanford wind energy farm study was published in the journal “Proceedings of that National Academy of Sciences”.

PICS: Hundreds of youth take to SA streets over climate change

Hundreds of youth in Cape Town and Pretoria marched on Friday to demand that the government urgently act on climate change.

About 300 people marched from Parliament to the City Hall in Cape Town to hand over a memorandum demanding government take “immediate action on the climate crises”.

The march was organised by the African Climate Youth Alliance and was part of the global Fridays for Future youth climate protest.

Protesters, the majority of whom were under the age of 18, marched through the city streets with placards chanting, “Hey hey, ho, ho, fossil fuels have got to go!” , “Save our planet” and “There’s no planet B”.

They want government to publicly declare that the climate crisis is happening; to place a moratorium on new coal, gas and oil mining licences; to have 100% renewable energy by 2030; and a mandatory education curriculum on climate change.

This follows a march on 15 March where thousands of school learners protested, calling on government to act against climate change.

A memorandum was handed over to Marian Nieuwoudt, Mayco member for Spatial Planning and Environment.

In Pretoria, about 150 people, mostly youth, from various environmental organisations picketed at the Union Buildings in an attempt to put pressure on government to act on climate change.

Some of the organisations included 350 Africa.org, Extinction Rebellion, Walter Sisulu Environmental Centre and Co-operative and Alternative Policy Centre (COPAC). The Well Worn Theatre Company, an organisation that uses theatre to bring awareness to climate change, also performed at the march.

But high school learners, some still dressed in their uniforms, and young children were at the forefront of the picket.

One of the organisers from 350 Africa.org, Alex Lenferna, said the upcoming Youth Day on Sunday was an important day to reflect on issues that affected young people in South Africa and one of those issues was climate change.

“Climate change is one of the gravest threats to young people’s future … If we do not act, we will be leaving them a world that is ravaged by climate change,” he said.

Solomon Kutumela from the Walter Sisulu Environmental Centre said the centre brought some high school learners from Mamelodi township to the march.

He said it was important for the learners to be at the march because they were passionate about fighting climate change and the march was a space for their voices to be heard.

Kutumela said the centre focuses on teaching learners about waste, energy, water and biodiversity in Mamelodi. “It has also inspired learners to take part in marches like these and think about careers in sustainable energy and environmental work,” he told GroundUp.

One of the learners from Mamelodi East, 15-year-old Jeffrey Mashela, said: “I’m here today to show that the environment is very important to us and as the youth, we should think about the next generation and how it is going to be for them.”

He urged government to listen to the voices of the youth. “That is why we are here today, to make [the government] listen,” he said.

Another learner from Mamelodi, Dzunani Makwakwa, said the world is going to change in the near future if we do not address climate change. “If we don’t stand up as the youth, change is not going to happen … We have to show the older generations and the generations that come after us that we care about our environment.”

COPAC Executive Manager, Jane Cherry, said the organisation was calling for a “deep and just transition” that would ensure that workers who previously worked on coal mines would be skilled to work in sustainable energy.

“We also don’t want power to be transferred from one big multinational corporation to another one that owns solar energy … We want workers to benefit from these sustainable alternatives,” she said.

Cherry said COPAC was currently drafting a People’s Climate Justice Charter that it hoped would eventually be adopted in Parliament.

“We are currently hosting roundtable talks with different groups … We recently had one with drought affected communities and we’re still going to have talks with students, organisations, youth, labour and the media,” she said.

This was to table the various groups’ demands and include it in the document.

The memorandum was accepted and signed by Calvin Humbles from the office of the President. He said it would be acknowledged within seven days.

Someone from the crowd shouted: “That’s not enough … Our President was on the board of Lonmin so how can we trust him to care about the environment?”

To which Humbles responded: “Let’s wait and see.”

Ruby Sampson is a grade 12 learner from Wynberg Girls High. She is one of the founders of the African Climate Alliance (ACA) and head of ACA’s youth wing. After the protest in March, Samoson said that they heard nothing from government. She said that although the first protest was “fantastic”, they didn’t really achieve much. This time they are marching and going to hand over a list of demands “from the youth of South Africa to government”. Photo: Ashraf Hendricks

Nicole Anthony (left) and her friend Widaad Abrahams from Lotus High joined the protest. Anthony, who is 16 and in grade 10, said that she joined the protest because “we are the future”. Anthony said that if nothing changes there will be no food and “we will die”. When questioning Anthony on why there aren’t many adults at the protests she said that “they already got their time”. “We are the next generations” she said. Photo: Ashraf Hendricks

“I want change,” said Zaahir Jacobs, a 13-years-old Grade 7 pupil from Littlewood Primary School in Mitchells Plain. Jacobs said that we need renewable resources in our lives like “sun and wind power”. Jacobs said adults don’t realise the importance of the climate crises. He said that he wants adults to stand with the youth. Photo: Ashraf Hendricks

Lily Shaw said that she isn’t attending school anymore because she is on a “permanent climate strike”. Shaw is 13 and a youth organiser for Extinction Rebellion Mzanzi . She on a climate strike since the start of the year and has entered its 24th week now. Shaw said that if she does nothing for her future “I’m going to be extinct as well as all of the other humans and most of the species”. Shaw said that climate change has become popular in the media but “when it actually matters, we’re not really not doing anything about it”. Photo: Ashraf Hendricks

Sasha Rodenacker, a 16-year-old grade 11 learner from Herzlia High, said that the protest was incredibly important because it was run by the youth. “We want a place to live as well,” he said. Rodenacker said that the youth are mostly active in this fight against climate change because “we are going to be living here so much longer than adults are”. Rodenacker said there were still a considerable number of people who deny climate change, or who don’t care, but “this issue is seriously going to affect you at some point”. “It’s better to start acting now, when we can maybe still do something”.

Storing Energy in Salt—Vattenfall Testing Technology at Berlin Plant

Swedish power company Vattenfall is testing a technology that stores energy in salt, with a goal of proving whether the process would be useful for storage of renewable energy such as from wind and solar farms. The pilot project, commissioned April 11 at the Reuter thermal power plant in Berlin (Figure 1), is being conducted with Swedish company SaltX Technology, which has said its system has been proven to store up to 10 times more energy in salt than in water, and for longer periods. SaltX’s technology uses salt crystals coated in a nano material, which is heated with electricity, with the heat released when the crystals are discharged.

SaltX on its website calls the system “Thermo-chemical energy storage,” saying the energy “is stored chemically, by separating salt from water, and then released by combining them again. The technology allows thermal energy to be stored and used hours, days, or months later,” for both small- and large-scale projects. The company says, “SaltX Thermo chemical energy storage can be charged with both electricity and heat and then be released as heat up to 500C (930F).”

The project at Reuter has a total storage capacity of 10 MWh and is the first test of the system on an industrial scale. Sandra Kühberger, head of media relations and content for Vattenfall in Germany, told POWER: “Data should be collected in the coming months to better understand the processes. After the pilot phase, [at the] end of summer, the gathered data will be evaluated.” Markus Witt of Vattenfall, who is responsible for the project, said, “Some questions are how large amounts of salt can be used, how quickly the storage medium reacts, and how the process can be controlled.”

Vattenfall and SaltX Technology initiated their collaboration in 2017, with the pilot plant installed over several months at Reuter. SaltX Technology says the nano-coated salt “is all-natural, very scalable and prevents corrosion. The salt has a good volumetric energy density and the nano-coating enables a long life to/for a low-cost material.” SaltX says the technology allows what it calls the “salt battery” to be charged thousands of times, with energy stored for weeks or months without loss.

“The energy sector is changing quickly, and we globally see an enormous need for energy storage. Germany is a country at the forefront of this development and we are proud to have Vattenfall as a partner. We are eager to launch our energy storage solution commercially as quickly as possible,” said Harald Bauer, CEO of SaltX Technology, in a statement.

Vattenfall said the project will run until the end of summer, with data and other results made available at the end of 2019. Vattenfall said the salt storage project is part of the company’s rebuilding of the Reuter plant, where Vattenfall said it will begin operation of Europe’s largest power-to-heat facility (p2h) later this year. That project is based on storage of hot water.

Kühberger told POWER: “By 2020, the p2h unit will provide district heating from electricity for up to 30,000 households. Vattenfall is investing almost €100 million [about $112 million] in the next two years. After the commissioning of all heat boilers in the project, the [coal-fired] unit C of Reuter can be decommissioned as planned from the heating season 2019/2020 on.”

Vattenfall is retiring Reuter C coal-fired unit as part of its plan to phase out coal-fueled generation in Berlin by 2030. Reuter today is a 160-MW combined heat and power (CHP) plant that first operated as a coal-fired plant in 1930 in the Spandau district of Berlin. The plant, like many others in the region, was demolished after World War II, but was rebuilt starting in 1948. It was converted to a CHP plant in 1956. The plant includes a flue gas scrubber, with the turbine operated by steam from a nearby waste incineration plant.
