Denmark's largest energy company to stop using coal by 2023

Australian VRF Battery Market sees a commercial-scale solar and storage demonstration by Energy Made Clean, Sumitomo Electric, and TNG, integrating vanadium redox flow systems with microgrids for grid-scale renewable energy reliability across Australia.

Key Points

A growing sector deploying vanadium redox flow batteries for scalable, long-life energy storage across Australia.

✅ Commercial demo by EMC, Sumitomo Electric, and TNG

✅ Integrates solar PV with containerized VRF systems

✅ Targets microgrids and grid-scale renewable reliability

Carnegie Wave Energy’s 100 per cent owned subsidiary, Energy Made Clean, is set to develop and demonstrate a commercial-scale solar and battery storage plant in Australia, after entering into a joint venture targeting Australia’s vanadium redox flow (VRF) battery market.

Carnegie said on Tuesday that EMC had signed a memorandum of understanding with Japanese company Sumitomo Electric Industries and ASX-listed TNG Limited to assess the potential applications of VRF batteries through an initial joint energy storage demonstration project in Australia.

The deal builds on a June 2015 MOU between EMC and emerging strategic metals company TNG, to establish the feasibility of Vanadium Redox batteries. And it comes less than two months after Carnegie took full ownership of the Perth-based EMC, which has established itself as one of the Australia’s foremost micro-grid and battery storage businesses, reflecting momentum in areas such as green hydrogen microgrids internationally.

Energy Made Clean’s main role in the partnership will be to identify commercial project site opportunities, while also designing and supplying a compatible balance of plant – likely to include solar PV – to integrate with the VRF containerised system being supplied by Sumitomo.

The demonstration will be of commercial size, to best showcase Sumitomo’s technology, the companies said; with each party contributing to their core competencies, and subsequently cooperating on the marketing and sales of VRF batteries.

As we have noted on RE before, vanadium redox flow batteries are tipped to be one of the key players in the booming global energy storage market, alongside innovations like gravity storage investment, as more and more renewable energy sources are brought onto grids around the world.

The batteries are considered uniquely suited to on- and off-grid energy storage applications, and emerging models like vehicle-to-building power, due to their scalability and long asset lives, with deep and very high cycling capability.

Australia, as well as being a key market for battery storage uptake, has seen a recent grid rule change that could impact big batteries, and has been noted for its potential to become a top global producer of vanadium – a metal found in a range of mineral deposits.

A number of Australian companies are already active in the local vanadium redox flow battery market, including miner Australian Vanadium – which recently inked a deal with Germany battery maker Gildemeister Energy Storage to sell its CellCube range of VRF batteries – and Brisbane based battery maker Redflow.

Energy Made Clean CEO John Davidson said the signing of the MOU would bring key industry innovators together to help revolutionise the vanadium redox flow battery market in Australia.

“This strategic MoU represents a compelling three-way tie-up of an emerging miner, a manufacturer and an integrator to accelerate the development of a major new energy growth market,” Davidson said.

Renewable Energy Market Reform aligns solar and wind with modern grid pricing, tackling intermittency via batteries and demand response, stabilizing wholesale power prices, and enabling capacity markets to finance flexible supply for deep decarbonization.

Key Points

A market overhaul that integrates variable renewables, funds flexibility, and stabilizes grids as solar and wind grow.

✅ Dynamic pricing rewards flexibility and demand response

✅ Capacity markets finance reliability during intermittency

✅ Smart grids, storage, HV lines balance variable supply

ALMOST 150 years after photovoltaic cells and wind turbines were invented, they still generate only 7% of the world’s electricity. Yet something remarkable is happening. From being peripheral to the energy system just over a decade ago, they are now growing faster than any other energy source and their falling costs are making them competitive with fossil fuels. BP, an oil firm, expects renewables to account for half of the growth in global energy supply over the next 20 years. It is no longer far-fetched to think that the world is entering an era of clean, unlimited and cheap, abundant electricity for all. About time, too. 

There is a $20trn hitch, though. To get from here to there requires huge amounts of investment over the next few decades, to replace old smog-belching power plants and to upgrade the pylons and wires that bring electricity to consumers. Normally investors like putting their money into electricity because it offers reliable returns. Yet green energy has a dirty secret. The more it is deployed, the more it lowers the price of power from any source. That makes it hard to manage the transition to a carbon-free future, during which many generating technologies, clean and dirty, need to remain profitable if the lights are to stay on. Unless the market is fixed, subsidies to the industry will only grow.

Policymakers are already seeing this inconvenient truth as a reason to put the brakes on renewable energy. In parts of Europe and China, investment in renewables is slowing as subsidies are cut back, even as Europe’s electricity demand continues to rise. However, the solution is not less wind and solar. It is to rethink how the world prices clean energy in order to make better use of it.

Shock to the system

At its heart, the problem is that government-supported renewable energy has been imposed on a market designed in a different era. For much of the 20th century, electricity was made and moved by vertically integrated, state-controlled monopolies. From the 1980s onwards, many of these were broken up, privatised and liberalised, so that market forces could determine where best to invest. Today only about 6% of electricity users get their power from monopolies. Yet everywhere the pressure to decarbonise power supply has brought the state creeping back into markets. This is disruptive for three reasons. The first is the subsidy system itself. The other two are inherent to the nature of wind and solar: their intermittency and their very low running costs. All three help explain why power prices are low and public subsidies are addictive.

First, the splurge of public subsidy, of about $800bn since 2008, has distorted the market. It came about for noble reasons—to counter climate change and prime the pump for new, costly technologies, including wind turbines and solar panels. But subsidies hit just as electricity consumption in the rich world was stagnating because of growing energy efficiency and the financial crisis. The result was a glut of power-generating capacity that has slashed the revenues utilities earn from wholesale power markets and hence deterred investment.

Second, green power is intermittent. The vagaries of wind and sun—especially in countries without favourable weather—mean that turbines and solar panels generate electricity only part of the time. To keep power flowing, the system relies on conventional power plants, such as coal, gas or nuclear, to kick in when renewables falter. But because they are idle for long periods, they find it harder to attract private investors. So, to keep the lights on, they require public funds.

Everyone is affected by a third factor: renewable energy has negligible or zero marginal running costs—because the wind and the sun are free. In a market that prefers energy produced at the lowest short-term cost, wind and solar take business from providers that are more expensive to run, such as coal plants, depressing wholesale electricity prices, and hence revenues for all.

Get smart

The higher the penetration of renewables, the worse these problems get—especially in saturated markets. In Europe, which was first to feel the effects, utilities have suffered a “lost decade” of falling returns, stranded assets and corporate disruption. Last year, Germany’s two biggest electricity providers, E.ON and RWE, both split in two. In renewable-rich parts of America, power providers struggle to find investors for new plants, reflecting U.S. grid challenges that slow a full transition. Places with an abundance of wind, such as China, are curtailing wind farms to keep coal plants in business.

The corollary is that the electricity system is being re-regulated as investment goes chiefly to areas that benefit from public support. Paradoxically, that means the more states support renewables, the more they pay for conventional power plants, too, using “capacity payments” to alleviate intermittency. In effect, politicians rather than markets are once again deciding how to avoid blackouts. They often make mistakes: Germany’s support for cheap, dirty lignite caused emissions to rise, notwithstanding huge subsidies for renewables. Without a new approach the renewables revolution will stall.

The good news is that new technology can help fix the problem.  Digitalisation, smart meters and batteries are enabling companies and households to smooth out their demand—by doing some energy-intensive work at night, for example. This helps to cope with intermittent supply. Small, modular power plants, which are easy to flex up or down, are becoming more popular, as are high-voltage grids that can move excess power around the network more efficiently, aligning with common goals for electricity networks worldwide.

The bigger task is to redesign power markets to reflect the new need for flexible supply and demand. They should adjust prices more frequently, to reflect the fluctuations of the weather. At times of extreme scarcity, a high fixed price could kick in to prevent blackouts. Markets should reward those willing to use less electricity to balance the grid, just as they reward those who generate more of it. Bills could be structured to be higher or lower depending how strongly a customer wanted guaranteed power all the time—a bit like an insurance policy. In short, policymakers should be clear they have a problem and that the cause is not renewable energy, but the out-of-date system of electricity pricing. Then they should fix it.

Uber Elevate eVTOL Batteries enable electric air taxis with advanced energy storage, lithium-ion cell quality, safety engineering, and zero-emissions performance for urban air mobility, ride-hailing aviation, and scalable battery pack development.

Key Points

Battery systems for Uber's electric air taxis, maximizing energy density, safety, and cycle life for urban air mobility.

✅ Ex-Tesla battery leader guides pack design and cell quality

✅ All-electric eVTOL targets zero-emissions urban air mobility

✅ Focus on safety, energy density, fast charge, and lifecycle

Celina Mikolajczak, a senior manager for battery pack development at Tesla, has been hired by Uber to help the ride-hail company’s “flying car” project get off the ground. It’s an important hire because it signals that Uber plans to get more involved in the engineering aspects of this outlandish-sounding project.

For six years, Mikolajczak served as senior manager and technical lead for battery technology, cell quality, and materials analysis. She worked with Tesla’s suppliers, tested the car company’s lithium-ion batteries for long-term use as the age of electric cars accelerates, oversaw quality assurance, and conducted “failure analysis” to drive battery cell production and design improvements. In other words, Mikolajczak was in charge of making sure the most crucial component in Tesla’s entire assembly line was top of the line.

Now she works for Uber — and not just for Uber, but for Uber Elevate, the absurdly ambitious air taxi service that hinges on the successful development of electric vertical take-off and landing (eVTOL) vehicles. There are practically zero electric planes in service today, and definitely none being used in a commercial ride-hail service. The hurdles to getting this type of service off the ground are enormous.

Her title at Uber is director of engineering and energy storage systems, and today marks her first week on the job. She joins Mark Moore, the former chief technologist for on-demand mobility at NASA’s Langley Research Center, who joined Uber almost a year ago to help lend a professional appearance to Elevate. Both serve under Jeff Holden, Uber’s head of product, who oversees the air taxi project.

Uber first introduced its plan to bring ride-sharing to the skies in a white paper last year. At the time, Uber said it wasn’t going to build its own eVTOL aircraft, but stood ready to “contribute to the nascent but growing VTOL ecosystem and to start to play whatever role is most helpful to accelerate this industry’s development.”

Instead, Uber said it would be partnering with a handful of aircraft manufacturers, real estate firms, and government regulators to better its chances of developing a fully functional, on-demand flying taxi service. It held a day-long conference on the project in Dallas in April, and plans to convene another one later this year in Los Angeles. In 2020, Uber says its aerial service will take off in three cities: LA, Dallas-Fort Worth, and Dubai.

UBER’S TAKING A MORE PROMINENT ROLE

Now, Uber’s taking a more prominent role in the design and manufacturing of its fleet of air taxis, which signals a stronger commitment to making this a reality — and also more of a responsibility if things eventually go south, as setbacks like Eviation's collapse underscore.

Perhaps most ambitiously, Uber says the aircraft it plans to use (but, importantly, do not exist yet) will run on pure battery-electric power, and not any hybrid of gasoline and electricity. Most of the companies exploring eVTOL admit that battery’s today aren’t light enough or powerful enough to sustain flights longer than just a few minutes, but many believe that battery technology will eventually catch up, with Elon Musk suggesting a three-year timeline for cheaper, more powerful cells.

Uber believes that in order to sustain a massive-scale new form of transportation, it will need to commit to an all-electric, zero-operational emissions approach from the start, even as potential constraints threaten the EV boom overall. And since the technology isn’t where it needs to be yet, the ride-hail company is taking a more prominent role in the development of the battery pack for its air taxi vehicles. Mikolajczak certainly has her work cut out for her.

PEI Electric Vehicle Incentives aim to boost EV adoption through subsidies and rebates, advocated by Renewable Transport PEI, with MLAs engagement, modeling Norway's approach, offsetting HST gaps, and making electric cars more competitive for Islanders.

Key Points

PEI Electric Vehicle Incentives are proposed subsidies and rebates to make EVs affordable and competitive for Islanders.

✅ Targets EV adoption with rebates up to 20 percent

✅ Modeled on Norway policies; offsets prior HST-era gaps

✅ Backed by Renewable Transport PEI engaging MLAs

Noah Ellis, assistant director of Renewable Transport P.E.I., is asking government to introduce incentives for Islanders to buy electric cars, as cost barriers remain a key hurdle for many.

RTPEI is a group composed of high school students at Colonel Gray going into their final year."We wanted to give back and contribute to our community and our country and we thought this would be a good way to do so," Ellis told Compass.

Meeting with government

"We want to see the government bring in incentives for electric vehicles, similar to New Brunswick's rebate program, because it would make them more competitive with their gasoline counterparts," Ellis said.

'We wanted to give back and contribute to our community … we thought this would be a good way to do so.'— Noah Ellis

Ellis said the group has spoken with opposition MLAs and is meeting with cabinet ministers soon to discuss subsidies for Islanders to buy electric cars, noting that Atlantic Canadians are less inclined to buy EVs compared to the rest of the country.

He referred to Norway as a prime example for the province to model potential incentives, even as Labrador's EV infrastructure gaps underscore regional challenges — a country that, as of last year, announced nearly 40 per cent of the nation's newly registered passenger vehicles as electric powered.

'Incentives that are fiscally responsible'

Ellis said they group isn't looking for anything less than a 20 per cent incentive on electric vehicles — 10 per cent higher than the provinces cancelled hybrid car tax rebate that existed prior to HST.

"Electric vehicle incentives do work we just have to work with economists and environmentalists, and address critics of EV subsidies, to find the right balance of incentives that are fiscally responsible for the province but will also be effective," Ellis said.

TransWest Express Power Line will deliver Wyoming wind energy to California via a 730-mile high-voltage corridor, integrating 3,000 MW from the Chokecherry and Sierra Madre project to strengthen the Western grid and decarbonization goals.

Key Points

A 730-mile line delivering up to 3,000 MW of Wyoming wind to Western states, improving clean energy reliability.

✅ 3,000 MW from Chokecherry and Sierra Madre turbines

✅ 730-mile route linking Wyoming to CA, AZ, NV markets

✅ Supports 60% by 2030, 100% by 2045 clean mandates

A conservative billionaire wants to build America's biggest wind farm in Wyoming and send the clean electricity to California.

Federal officials have approved another section of the 730-mile TransWest Express power line, in line with a renewable transmission rule aimed at speeding upgrades, which would carry energy from Philip Anschutz's Chokecherry and Sierra Madre wind farm to potential customers in California, Arizona and Nevada. The 1,000-turbine, 3,000-megawatt wind project, which has been in the works for a decade, would be built in south-central Wyoming, in one of the windiest spots in the continental U.S.

Supporters say the massive power project would help California meet its clean energy goals, in part because Wyoming winds tend to blow strong into the evening, as the sun sets over the Pacific and the Golden State's many solar farms go offline, though expanding battery storage is starting to fill that gap. Under California law, electric utilities are required to get 50% of their power from renewable sources by 2030. The state Senate passed a bill Wednesday that would raise the clean energy mandate to 60% by 2030 and 100% by 2045.

The Denver-based Anschutz Corporation hasn't inked any contracts to sell the electricity its Wyoming wind farm would generate. But company officials are confident demand will materialize by the time they're ready to build turbines. Construction of roads and other project infrastructure started last year and picked back up in April after a winter hiatus.

The developer has already spent $100 million developing the wind farm and power line, and expects to spend a combined $8 billion on the two projects.

After an extensive environmental review, the U.S. Forest Service issued a permit Wednesday for portions of the TransWest Express transmission line that would cross through 19 miles of the Uinta-Wasatch-Cache and Manti-La Sal national forests in Utah.

"It's another step forward in the process of making this line a reality, and being able to provide a path that allows California, Arizona and Nevada to access the high volumes of renewable energy supplies that are available in Wyoming," said Kara Choquette, a spokesperson for the Anschutz subsidiaries developing the power project.

Between the Forest Service approval and a Bureau of Land Management permit issued in December, the developer now has the go-ahead to build about two-thirds of the 730-mile route, Choquette said, progress that comes as the U.S. grid overhaul for renewables accelerates nationwide. Company officials are reaching out to the roughly 450 private landowners along the proposed route. They must also apply for a state permit in Wyoming, and 14 county-level permits in Wyoming, Colorado, Utah and Nevada.

But Anschutz's Chokecherry and Sierra Madre wind farm is a reminder that Trump can't stop the ongoing transition from coal to cleaner sources of energy, which is being driven largely by market forces. Solar, wind and natural gas, which burns more cleanly than coal, are now the cheapest sources of new electricity across much of the country, even as Texas grid constraints sometimes force High Plains turbines to shut down during oversupply. Utility industry executives are abandoning coal and embracing renewable energy. And the American solar industry employs more people than coal or natural gas.

States and local governments in California, New York and elsewhere have also forged ahead with policies to reduce climate emissions, including New York's largest offshore wind project recently approved. So have major companies like Apple, Facebook and Google, which have invested billions of dollars in renewable energy.

"The (Trump) administration is so out of step with reality right now. The trend is powerful, whether it's coming the cities or corporations, or from the coastal states," said Don Furman, a former utility executive who now advocates for greater sharing of renewable energy across state lines in the West.

Clean energy advocates say the 3,000-megawatt Wyoming wind farm is an especially powerful example of the economic case for renewable energy, because its proprietor is Anschutz, a longtime fossil fuel magnate and major donor to Republican politicians.

"I don't think Philip Anschutz would be putting his money here if he thought this was a bad business bet," Furman said.

The Forest Service also issued a permit Wednesday for the 416-mile Energy Gateway South power line, which would run through Wyoming, Colorado and Utah, traversing nine miles of the same national forests TransWest Express would cross. Gateway South is part of the 1,900-mile Energy Gateway transmission project being developed by Warren Buffett's PacifiCorp utility, which serves customers across six western states.

PacifiCorp officials say the $6 billion transmission project is needed to meet growing electricity demand. They've also pitched the power lines as another opportunity to transmit wind power from Wyoming to California and other coastal states. Critics, though, see Energy Gateway as costly and unnecessary — and they're worried Californians would end up paying the price through higher electricity rates.

Kemper County power plant costs and delays highlight lignite coal gasification, syngas production, carbon capture targets, and looming rate plans as Mississippi Power navigates Public Service Commission oversight and shareholder-ratepayer risk.

Key Points

Costs exceed $7.5B with repeated delays; rate impacts loom as syngas, lignite, and carbon capture systems mature.

✅ Estimate tops $7.5B; customers could fund about $4.3B

✅ Carbon capture target: 65% CO2 via syngas from lignite

✅ Rate plans pending before the Public Service Commission

A Mississippi utility on Monday delayed making proposals for how its customers should pay for an ever-more-expensive power plant, even as the estimated cost of the facility crossed $7.5 billion.

The Kemper County power plant will be tasked with mining lignite coal a few hundred yards away from the plant. That coal is moved through a process that will convert it to syngas. The syngas is then used to drive the energy output of the plant, and the resulting electricity is then moved into the grid, where transmission projects influence regional reliability and capacity.

Thomas Fanning, CEO of parent Southern Co., told shareholders in May that Mississippi Power would file rate plans for its Kemper County power plant this month. But still unable to operate the plant steadily enough to declare it finished, Mississippi Power punted, instead asking to hold rates level for 11 months to pay off costs that have already been approved by regulators.

Mississippi Power says it now hopes to reach commercial operation in June. The plant is more than three years behind schedule, with 10 delays announced in the past 18 months. It was originally supposed to cost $2.9 billion.

The company also said monday that it will have to replace troublesome parts of the facility much sooner than expected, including units that cool the synthetic gas produced from soft lignite coal by two gasifier units, plus ash handling systems in the gasifiers.

Kemper is designed to take synthetic gas, pipe it through a chemical plant to remove carbon dioxide and other chemicals, and then burn the gas in turbines to generate electricity. It’s designed to capture 65 percent of carbon dioxide from the coal, releasing only as much of the climate-warming gas as a typical natural gas plant. It’s a key effort nationally to maintain coal as a viable fuel source, even as coal unit retirements proceed in other states.

Mississippi Power raised its estimate of Kemper’s cost by $209.4 million, with shareholders absorbing $185.9 million, while ratepayers could be asked to pay $23.5 million. Overall, customers could be asked to pay $4.3 billion. Southern shareholders have agreed to absorb $3.1 billion, which has risen by $500 million since November.

The elected three-member Public Service Commission in 2015 allowed the company to raise rates on its 188,000 customers by $126 million a year. That paid for $840 million in Kemper work, which began generating electricity in 2014 using piped-in natural gas. Some items covered by that 15 percent rate increase will be paid off in coming months, but Mississippi Power now proposes to repay costs from regulatory proceedings earlier than originally projected.

In testimony filed with the Public Service Commission, Mississippi Power Chief Financial Officer Moses Fagin said that keeping rates level would reduce whiplash to customers when rates rise later to pay for Kemper, would pay off accumulated costs more quickly and would help the company wean itself off financial support from Southern Co. while maintaining credit ratings and positioning for a possible bond rating upgrade over time.

“Cash flow is important to the company in maintaining its current ratings and beginning to rebuild its credit strength on a more independent basis apart from the extraordinary parental support that has been required in recent years to maintain financial integrity,” Fagin testified.

Spokesman Jeff Shepard said Mississippi Power is still drawing up two rate plans — one requiring a sharp, immediate rate increase, and a “rate mitigation plan” that might cushion increases amid declining returns in coal markets. He said the company isn’t sure when it will file them. Fagin suggested the Public Service Commission set a new deadline of March 2, 2018.
