Feds announce $500M contract with Edmonton company for green electricity

China Compressed-Air Energy Storage enables grid flexibility using salt caverns in Jiangsu, delivering long-duration storage for wind and solar, 60 MW capacity, dispatchable power, and low-cost, safe, round-the-clock clean energy integration.

Key Points

Stores off-peak power by compressing air in salt caverns, then drives turbines on demand to balance renewables.

✅ 60 MW Jintan plant connects to grid; commercial CAES milestone

✅ Uses salt caverns; low-cost long-duration storage; high safety

✅ Balances wind and solar; improves grid flexibility and reliability

China is set to connect its first commercial compressed-air energy storage plant to the grid as it seeks more ways to harness fast-growing clean power resources, including new hydropower alongside other long-duration options such as gravity power technologies for around-the-clock use.

China Huaneng Group Co. said its Jiangsu Jintan Salt Cave project recently underwent four days of successful trials and is now ready for commercial operations. The 60-megawatt plant will be the largest compressed air energy storage plant built anywhere in the world since 1991, and the first in China outside of small-scale technology demonstration projects, as China's electricity demand patterns remain in flux, according to BloombergNEF.

The plant will use electricity at night when demand is low to pump air into an underground salt cavern. Then, when demand is high during the day, it can release the compressed air at high enough pressure to spin a turbine and produce electricity, aligning with projections that 60% electricity by 2060 could be reached according to industry outlooks.

Underground compressed air is considered one of the least costly forms of long-term energy storage and has low safety concerns, according to BloombergNEF. But its reliance on certain topographical features such as underground caverns may limit wider deployment, a challenge shared by other regions weighing large-scale storage options for reliability. It’s gained a foothold in China, with nearly four gigawatts of projects in the pipeline, while there are less than two gigawatts combined planned in the rest of the world. Shandong province said just this week in this year's work plan that it would build three projects using the technology.

The Jintan salt caves in Jiangsu, China’s second-biggest provincial economy just north of Shanghai, can store about 10 million cubic meters of gas, enough to power four gigawatts of compressed air plants, according to a Science and Technology Daily report from last year. 

Energy storage is a key part of China’s plan to build a larger and more flexible grid as it tries to peak carbon emissions before 2030 and zero them out before 2060, alongside continued nuclear energy development to stabilize baseload supply. The country is adding a world-leading amount of wind and solar power every year, but their intermittency strains grids that need to be able to deliver electricity all the time, spurring interest in green hydrogen as a flexible complement. China has set targets of 30 gigawatts of new-energy storage by 2025 and 120 gigawatts of pumped hydro storage by 2030.

EV Charging Coal and Oil Claim: Fact-check of kWh, CO2 emissions, and electricity grid mix shows 70 lb coal or ~8 gallons oil per 66 kWh, with renewables and natural gas reducing lifecycle emissions.

Key Points

A viral claim on EV charging overstates oil use; accurate figures depend on grid mix: ~70 lb coal or ~8 gallons oil.

✅ About 70 lb coal or ~8 gal oil per 66 kWh, incl. conversion losses

✅ EVs average ~100 g CO2 per mile vs ~280 g for 30 mpg cars

✅ Grid mix includes renewables, nuclear, natural gas; oil use is low

The claim: Average electric car requires equivalent of 85 pounds of coal or six barrels of oil for a single charge

The Biden administration has pledged to work towards decarbonizing the U.S. electricity grid by 2035. And the recently passed $1.2 trillion infrastructure bill provides funding for more electric vehicle (EV) charging infrastructure, including EV charging networks across the country under current plans.

However, a claim that electric cars require an inordinate amount of oil or coal energy to charge has appeared on social media, even as U.S. plug-ins traveled 19 billion miles on electricity in 2021.

“An average electric car takes 66 KWH To charge. It takes 85 pounds of coal or six barrels of oil to make 66 KWH,” read a Dec 1 Facebook post that was shared nearly 500 times in a week. “Makes absolutely no sense.” 

The post included a stock image of an electric car charging, though actual charging costs depend on local rates and vehicle efficiency.

This claim is in the ballpark for the coal comparison, but the math on the oil usage is wildly inaccurate.

It would take roughly 70 pounds of coal to produce the energy required to charge a 66 kWh electric car battery, said Ian Miller, a research associate at the MIT Energy Initiative. That's about 15 pounds less than is claimed in the post.

The oil number is much farther off.

While the post claims that it takes six barrels of oil to charge a 66 kWh battery, Miller said the amount is closer to 8 gallons  — the equivalent of 20% of one barrel of oil.

He said both of his estimates account for energy lost when fossil fuels are converted into electricity. 

"I think the most important question is, 'How do EVs and gas cars compare on emissions per distance?'," said Miller. "In the US, using average electricity, EVs produce roughly 100 grams of CO2 per mile."

He said this is more than 60% less than a typical gasoline-powered car that gets 30 mpg, aligning with analyses that EVs are greener in all 50 states today according to recent studies. Such a vehicle produces roughly 280 grams of CO2 per mile.

Lifecycle analyses also show that the CO2 from making an EV battery is not equivalent to driving a gasoline car for years, which often counters common misconceptions.

"If you switch to an electric vehicle, even if you're using fossil fuels (to charge), it's just simply not true that you'll be using more fossil fuel," said Jessika Trancik, a professor at the Massachusetts Institute of Technology who studies the environmental impact of energy systems.  

However, she emphasized electric cars in the U.S. are not typically charged using only energy from coal or oil, and that electricity grids can handle EVs with proper management.

The U.S. electricity grid relies on a diversity of energy sources, of which oil and coal together make up about 20 percent, according to a DOE spokesperson. This amount is likely to continue to drop as renewable energy proliferates in the U.S., even as some warn that state power grids will be challenged by rapid EV adoption. 

"Switching to an electric vehicle means that you can use other sources, including less carbon-intensive natural gas, and even less carbon-intensive electricity sources like nuclear, solar and wind energy, which also carry with them health benefits in the form of reduced air pollutant emissions," said Trancik. 

Our rating: Partly false
Based on our research, we rate PARTLY FALSE the claim that the average electric car requires the equivalent of 85 pounds of coal or six barrels of oil for a single charge. The claim is in the ballpark on coal consumption, as an MIT researcher estimates that around 70 pounds. But the oil usage is only about 8 gallons, which is 20% of one barrel. And the actual sources of energy for an electric car vary depending on the energy mix in the local electric grid.

EV Adoption Limits highlight that electric vehicles alone cannot meet emissions targets; life cycle assessment, carbon budgets, clean grids, public transit, and battery materials constraints demand broader decarbonization strategies, city redesign, and active travel.

Key Points

EV Adoption Limits show EVs alone cannot hit climate targets; modal shift, clean grids, and travel demand are essential.

✅ 350M EVs by 2050 still miss 2 C goals without major mode shift

✅ Grid demand rises 41%, requiring clean power and smart charging

✅ Battery materials constraints need recycling, supply diversification

Today there are more than seven million electric vehicles (EVs) in operation around the world, compared with only about 20,000 a decade ago. It’s a massive change – but according to a group of researchers at the University of Toronto’s Faculty of Applied Science & Engineering, it won’t be nearly enough to address the global climate crisis. 

“A lot of people think that a large-scale shift to EVs will mostly solve our climate problems in the passenger vehicle sector,” says Alexandre Milovanoff, a PhD student and lead author of a new paper published in Nature Climate Change. 

“I think a better way to look at it is this: EVs are necessary, but on their own, they are not sufficient.” 

Around the world, many governments are already going all-in on EVs. In Norway, for example, where EVs already account for half of new vehicle sales, the government has said it plans to eliminate sales of new internal combustion vehicles by 2025. The Netherlands aims to follow suit by 2030, with France and Canada's EV goals aiming to follow by 2040. Just last week, California announced plans to ban sales of new internal combustion vehicles by 2035.

Milovanoff and his supervisors in the department of civil and mineral engineering – Assistant Professor Daniel Posen and Professor Heather MacLean – are experts in life cycle assessment, which involves modelling the impacts of technological changes across a range of environmental factors. 

They decided to run a detailed analysis of what a large-scale shift to EVs would mean in terms of emissions and related impacts. As a test market, they chose the United States, which is second only to China in terms of passenger vehicle sales. 

“We picked the U.S. because they have large, heavy vehicles, as well as high vehicle ownership per capita and high rate of travel per capita,” says Milovanoff. “There is also lots of high-quality data available, so we felt it would give us the clearest answers.” 

The team built computer models to estimate how many electric vehicles would be needed to keep the increase in global average temperatures to less than 2 C above pre-industrial levels by the year 2100, a target often cited by climate researchers. 

“We came up with a novel method to convert this target into a carbon budget for U.S. passenger vehicles, and then determined how many EVs would be needed to stay within that budget,” says Posen. “It turns out to be a lot.” 

Based on the scenarios modelled by the team, the U.S. would need to have about 350 million EVs on the road by 2050 in order to meet the target emissions reductions. That works out to about 90 per cent of the total vehicles estimated to be in operation at that time. 

“To put that in perspective, right now the total proportion of EVs on the road in the U.S. is about 0.3 per cent,” says Milovanoff. 

“It’s true that sales are growing fast, but even the most optimistic projections of an electric-car revolution suggest that by 2050, the U.S. fleet will only be at about 50 per cent EVs.” 

The team says that, in addition to the barriers of consumer preferences for EV deployment, there are technological barriers such as the strain that EVs would place on the country’s electricity infrastructure, though proper grid management can ease integration. 

According to the paper, a fleet of 350 million EVs would increase annual electricity demand by 1,730 terawatt hours, or about 41 per cent of current levels. This would require massive investment in infrastructure and new power plants, some of which would almost certainly run on fossil fuels in some regions. 

The shift could also impact what’s known as the demand curve – the way that demand for electricity rises and falls at different times of day – which would make managing the national electrical grid more complex, though vehicle-to-grid strategies could help smooth peaks. Finally, there are technical challenges stemming from the supply of critical materials for batteries, including lithium, cobalt and manganese. 

The team concludes that getting to 90 per cent EV ownership by 2050 is an unrealistic scenario. Instead, what they recommend is a mix of policies, rather than relying solely on a 2035 EV sales mandate as a singular lever, including many designed to shift people out of personal passenger vehicles in favour of other modes of transportation. 

These could include massive investment in public transit – subways, commuter trains, buses – as well as the redesign of cities to allow for more trips to be taken via active modes such as bicycles or on foot. They could also include strategies such as telecommuting, a shift already spotlighted by the COVID-19 pandemic. 

“EVs really do reduce emissions, which are linked to fewer asthma-related ER visits in local studies, but they don’t get us out of having to do the things we already know we need to do,” says MacLean. “We need to rethink our behaviours, the design of our cities, and even aspects of our culture. Everybody has to take responsibility for this.” 

The research received support from the Hatch Graduate Scholarship for Sustainable Energy Research and the Natural Sciences and Engineering Research Council of Canada.

BC Hydro Vehicle-to-Grid Pilot enables EVs to deliver V2G power, using bidirectional charging to provide grid services, clean energy resilience, and emergency power for microgrids, critical infrastructure, and storm response.

Key Points

BC Hydro's V2G pilot uses parked EVs as mobile batteries, supplying bidirectional power to the grid for resilience.

✅ Medium- and heavy-duty EV integration via 60 kW charger

✅ Supports critical infrastructure and storm response

✅ Cleaner, faster alternative to diesel generators

BC Hydro has unveiled an innovative pilot project designed to enable electric vehicles (EVs) to contribute electricity back to the power grid, with some owners able to sell electricity back to the grid through managed programs, effectively transforming these vehicles into mobile energy storage units that function as capacity on wheels for the electricity system.

The utility company recently announced the successful trial of the vehicle-to-grid program, allowing for the transfer of electricity from the batteries of medium- and heavy-duty EVs back to the electrical grid. This surplus electricity can be utilized in various ways, including supporting emergency response efforts by energizing critical infrastructure and to power buildings during natural disasters or major storms. It offers a cleaner, faster, and more flexible alternative to conventional methods like the use of diesel generators.

BC Hydro's President and CEO, Chris O'Riley, highlighted the significance of this initiative, stating, "The average car is parked 95 per cent of the time, and with the evolution of technology solutions like vehicle-to-grid, stationary vehicles hold the potential to become mobile batteries, powered by clean and affordable electricity."

The successful test was conducted using a Lion Electric school bus provided by Lynch Bus Lines, which was connected to a 60-kilowatt charger, illustrating BC Hydro's rollout of faster electric vehicle charging across the province. BC Hydro pointed out that the typical bus battery holds 66 kilowatts of electricity, sufficient to power 24 single-family homes with electric heating for two hours. Therefore, if 1,000 of these buses were converted to electric power, they could collectively supply electricity to 24,000 homes for two hours.

This groundbreaking project is a collaborative effort between BC Hydro, Powertech, and Coast to Coast Experience, with funding support from the provincial government amid study findings that B.C. may need to double its power output to meet transport electrification.

While this pilot marks the first of its kind in Canada, similar technology has already been successfully implemented in Europe and the United States, including California's efforts to leverage EVs for grid stability that offer promising potential for enhancing the energy landscape and sustainability in the region.

Separately, Nova Scotia Power plans to pilot electric vehicle to grid integration in Atlantic Canada, underscoring growing national interest in V2G approaches.

EV battery supply strategies weigh in-house cell manufacturing against supplier contracts, optimizing costs, scale, and supply-chain resilience for electric vehicles. Automakers like Tesla, GM-LG Chem, VW-Northvolt, and Ford balance gigafactories, joint ventures, and procurement risks.

Key Points

How automakers secure EV battery cells by balancing cost, scale, tech risk, and supply-chain control to meet demand.

✅ In-source cells via gigafactories, JVs, and proprietary chemistries

✅ Contract with LG Chem, Panasonic, CATL, SKI to diversify supply

✅ Manage costs, logistics, IP, and technology obsolescence risks

Auto makers, pumping billions of dollars into developing electric cars, are now facing a critical inflection point as they decide whether to get more involved with manufacturing the core batteries or buy them from others.

Batteries are one of an electric vehicle’s most expensive components, accounting for between a quarter and a third of the car’s value. Driving down their cost is key to profitability, executives say.

But whereas the internal combustion engine traditionally has been engineered and built by auto makers themselves, battery production for electric cars is dominated by Asian electronics and chemical firms, such as LG Chem Ltd. and Panasonic Corp. , and newcomers like China’s Contemporary Amperex Technology Co.

California, the U.S.’s largest car market, said last month it would end the sale of new gasoline- and diesel-powered passenger cars by 2035, putting pressure on the auto industry to accelerate its shift to electric vehicles in the coming years.

The race to lock in supplies for electric cars has auto makers taking varied paths, with growing Canada-U.S. collaboration across supply chains.

While most make the battery pack, a large metal enclosure often lining the bottom of the car, they also need the cells that are bundled together to form the core electricity storage.

Tesla several years ago opened its Gigafactory in Nevada to make batteries with Panasonic, which in the shared space would produce cells for the packs. The electric-car maker wanted to secure production specifically for its own models and lower manufacturing and logistics costs.

Now it is looking to in-source more of that production.

While Tesla will continue to buy cells from Panasonic and other suppliers, it is also working on its own cell technology and production capabilities, aiming for cheaper, more powerful batteries to ensure it can keep up with demand for its cars, said Chief Executive Elon Musk last month.

Following Tesla’s lead, General Motors Co. and South Korea’s LG Chem are putting $2.3 billion into a nearly 3-million-square-foot factory in Lordstown, Ohio, highlighting opportunities for Canada to capitalize on the U.S. EV pivot as supply chains evolve, which GM says will eventually produce enough battery cells to outfit hundreds of thousands of cars each year.

In Europe, Volkswagen AG is taking a similar path, investing about $1 billion in Swedish battery startup Northvolt AB, including some funding to build a cell-manufacturing plant in Salzgitter, Germany, as part of a joint venture, and in North America, EV assembly deals in Canada are putting it in the race as well.

Others like Ford Motor Co. and Daimler AG are steering clear of manufacturing their own cells, with executives saying they prefer contracting with specialized battery makers.

Supply-chain disruptions, including lithium shortages, have already challenged some new model launches and put projects at risk, auto makers say.

For instance, Ford and VW have agreements in place with SK Innovation to supply battery cells for future electric-vehicle models. The South Korean company is building a factory in Georgia to help meet this demand, but a fight over trade secrets has put the plant’s future in jeopardy and could disrupt new model launches, both auto makers have said in legal filings.

GM executives say the risk of relying on suppliers has pushed them to produce their own battery cells, albeit with LG Chem.

“We’ve got to be able to control our own destiny,” said Ken Morris, GM’s vice president of electric vehicles.

Bringing the manufacturing in house will give the company more control over the raw materials it purchases and the battery-cell chemistry, Mr. Morris said.

But establishing production, even in a joint venture, is a costly proposition, and it won’t necessarily ensure a timely supply of cells. There are also risks with making big investments on one battery technology because a breakthrough could make it obsolete.

Ford cites those factors in deciding against a similar investment for now.

The company sees the industry’s conventional model of contracting with independent suppliers to build parts as better suited to its battery-cell needs, Ford executive Hau Thai-Tang told analysts in August.

“We have the competitive tension with dealing with multiple suppliers, which allows us to drive the cost down,” Mr. Thai-Tang said, adding that the company expects to pay prices for cells in line with GM and Tesla.

Meanwhile, Ford can leave the capital-intensive task of conducting the research and setting up manufacturing facilities to the battery companies, Mr. Thai-Tang said.

Germany’s Daimler has tried both strategies.

The car company made its own lithium-ion cells through a subsidiary until 2015. But the capital required to scale up was better spent elsewhere, said Ola Källenius, Daimler’s chief executive officer.

The auto maker instead signed long-term supply agreements with Asian companies like Chinese battery-maker CATL and Farasis Energy (Ganzhou) Co., which Daimler invested in last year.

The company has said it is spending roughly $23.6 billion on purchase agreements but keeping its battery research in-house.

“Let’s rather put that capital into what we do best, cars,” Mr. Källenius said.

UK Renewable Energy Auction secures 10 GW for the grid at record-low costs, led by offshore wind, floating wind, solar, and onshore wind, with inflation-indexed CfDs delivering £37/MWh strike prices and enhanced energy security.

Key Points

Government CfDs add 10 GW of low-cost renewables to the UK grid via offshore wind, floating wind, and solar.

✅ 10 GW capacity: 7 GW offshore wind, 2.2 GW solar, 0.9 GW onshore wind

✅ Record-low £37/MWh offshore; floating wind at £87/MWh CfD strikes

✅ 15-year indexed contracts cut exposure to volatile gas prices

The United Kingdom will add 10 gigawatts (GW) of renewable energy capacity to its power grid at one-quarter the cost of fossil gas after concluding its biggest-ever renewable energy auction for new renewable supplies.

The “remarkable new UK renewable auction” will meet one-eighth of the country’s current electricity demand at record low prices of just £37 per megawatt-hour for offshore wind and £87 for floating offshore systems (a dynamic echoed as wind power gains in Canada across other markets), tweeted Carbon Brief Deputy Editor Simon Evans.

“The government is increasing its reliance on a local supply of renewables amid soaring UK power prices driven by a surge in the cost of natural gas following Russia’s invasion of Ukraine,” Bloomberg Green reports. Offshore wind energy “will add about seven gigawatts of clean power capacity to the nation’s fleet from 2026, bringing Britain closer to its target of installing 50 gigawatts by the end of the decade.”

The awards also include 2.2 gigawatts (that’s 2.2 billion watts) of solar and 900 megawatts of onshore wind, even as the UK faces a renewables backlog on some projects, Bloomberg says.

“Eye-watering gas prices are hitting consumers across Europe,” said UK Business and Energy Secretary Kwasi Kwarteng. “The more cheap, clean power we generate within our own borders, the better protected we will be from volatile gas prices that are pushing up bills.”

Citing government figures, Bloomberg says wind generation costs came in 5.8% lower than the previous auction in 2019, reflecting momentum in a sector set to become a trillion-dollar business this decade. Some of the winning bidders included Ørsted, Iberdrola’s Scottish Power unit, Vattenfall, and a consortium of AB Ignitis Grupe, EDP Renovaveis, and Engie.

“Offshore wind power costs have fallen dramatically in recent years as the UK supported the industry to scale up and industrialize production of larger, more efficient turbines,” the news story states. Now, “the decline in price developers are willing to accept comes even after the cost of wind turbines rose in recent months as prices increased for key metals like steel and supply chain disruptions created expensive delays.”

The 15-year, fixed-price contracts will be adjusted for inflation when the turbines are ready to start delivering electricity, offering lessons for the U.S. wind sector on contract design.
