U.S. engineers have found a way to make lithium batteries that are smaller, lighter, longer lasting and capable of recharging in seconds.

The researchers believe the quick-charging batteries could open up new applications, including better batteries for electric cars.

And because they use older materials in a new way, the batteries could be available for sale in two to three years, a team from Massachusetts Institute of Technology reported in the journal Nature.

Current rechargeable lithium batteries can store large amounts of energy, making them long-running. But they are stingy about releasing their power, making them discharge energy slowly and require hours to recharge.

Scientists traditionally have blamed slow-moving lithium ions — which carry charge across the battery — for this sluggishness.

However, about five years ago, Gerbrand Ceder and a team at MIT discovered that lithium ions in traditional lithium iron phosphate battery material actually move quite quickly.

"It turned out there were other limitations," Ceder said in a telephone interview.

Ceder and colleagues discovered that lithium ions travel through tunnels accessed from the surface of the material. If a lithium ion at the surface is directly in front of a tunnel entrance, it can quickly deliver a charge. But if the ion is not at the entrance, it cannot easily move there, making it less efficient at delivering a charge.

Ceder and colleagues remedied this by revamping the battery recipe. "We changed the composition of the base material and we changed the way it is made — the heat treatment," Ceder said.

This created many smooth tunnels in the material that allow the ions to slip in and out easily. "The trick was knowing what to change," he said.

Using their new processing technique, the team made a small battery that could be fully charged in 10 to 20 seconds.

Ceder thinks the material could lead to smaller, lighter batteries because less material is needed for the same result.

And because they simply tinkered with a material already commonly used for batteries, it could be easily adapted for commercial use.

"If manufacturers decide they want to go down this road, they could do this in a few years," Ceder said.

One glitch, Ceder said, would be handling the extra surge of power. "All of the wiring has to get beefed up," he said.

Global Energy War Escalates: Price Hikes and Instability

Russia-Ukraine Energy War disrupts infrastructure, oil, gas, and electricity, triggering supply shocks, price spikes, and inflation. Global markets face volatility, import risks, and cybersecurity threats, underscoring energy security, grid resilience, and diversified supply.

 

Key Points

It is Russia's strategic targeting of Ukraine's energy system to disrupt supplies, raise prices, and hit global markets.

✅ Attacks weaponize energy to strain Ukraine and allies

✅ Supply shocks risk oil, gas, and electricity price spikes

✅ Urgent need for cybersecurity, grid resilience, diversification

 

Russia's targeting of Ukraine's energy infrastructure has unleashed an "energy war" that could lead to widespread price increases, supply disruptions, and ripple effects throughout the global energy market, felt across the continent, with warnings of Europe's energy nightmare taking shape.

This highlights the unprecedented scale and severity of the attacks on Ukrainian energy infrastructure. These attacks have disrupted power supplies, prompting increased electricity imports to keep the lights on, hindered oil and gas production, and damaged refineries, impacting Ukraine and the broader global energy system.


Energy as a Weapon

Experts claim that Russia's deliberate attacks on Ukraine's energy infrastructure represent a strategic escalation, amid energy ceasefire violations alleged by both sides, demonstrating the Kremlin's willingness to weaponize energy as part of its war effort. By crippling Ukraine's energy system, Russia aims to destabilize the country, inflict suffering on civilians, and undermine Western support for Ukraine.


Impacts on Global Oil and Gas Markets

The ongoing attacks on Ukraine's energy infrastructure could significantly impact global oil and gas markets, leading to supply shortages and dramatic price increases, even as European gas prices briefly returned to pre-war levels earlier this year, underscoring extreme volatility. Ukraine's oil and gas production, while not massive in global terms, is still significant, and its disruption feeds into existing anxieties about global energy supplies already affected by the war.


Ripple Effects Beyond Ukraine

The impacts of the "energy war" won't be limited to Ukraine or its immediate neighbours. Price increases for oil, gas, and electricity are expected worldwide, further fueling inflation and exacerbating the global cost of living crisis.  Additionally, supply disruptions could disproportionately affect developing nations and regions heavily dependent on energy imports, making targeted energy security support to Ukraine and other vulnerable importers vital.


Vulnerability of Energy Infrastructure

The attacks on Ukraine highlight the vulnerability of critical energy infrastructure worldwide, as the country prepares for winter under persistent threats. The potential for other state or non-state actors to use similar tactics raises concerns about security and long-term stability in the global energy sector.


Strengthening Resilience

Experts emphasize the urgent need for global cooperation in strengthening the resilience of energy infrastructure. Investments in cybersecurity, diverse energy sources, and decentralized grids are crucial for mitigating the risks of future attacks, with some arguing that stepping away from fossil fuels would improve US energy security over time. International cooperation will be key in identifying vulnerable areas and providing aid to nations whose infrastructure is under threat.


The Unpredictable Future of Energy

The "energy war" unleashed by Russia has injected a new level of uncertainty into the global energy market. In addition to short-term price fluctuations and supply issues, the conflict could accelerate the long-term transition towards renewable energy sources and reshape how nations approach energy security.

BC Hydro activates "winter payment plan"

BC Hydro Winter Payment Plan lets customers spread electricity bills over six months during cold weather, easing costs amid colder-than-average temperatures in British Columbia, with low-income conservation support, energy-saving kits, and insulation upgrades.

 

Key Points

Allows BC Hydro customers to spread winter electricity bills over six months, with added low-income efficiency support.

✅ Spread Dec-Mar bills across six months

✅ Eases costs during colder-than-average temperatures

✅ Includes low-income conservation and energy-saving kits

 

As colder temperatures set in across the province again this weekend, BC Hydro says it is activating its winter payment plan to give customers the opportunity to spread out their electricity bills as demand can reach record levels during extreme cold periods.

"Our meteorologists are predicting colder-than-average temperatures will continue over the next of couple of months and we want to provide customers with help to manage their payments," said Chris O'Riley, BC Hydro's president.

All BC Hydro customers will be able to spread payments from the billing period spanning Dec. 1, 2017 to March 31, 2018 over a six-month period.

Cold weather in the second half of December 2017 led to surging electricity demand that was higher than the previous 10-year average and has at times hit all-time highs during peak usage periods, according to BC Hydro.

Hydro operations also respond to summer conditions, as drought and low rainfall can force adjustments in power generation strategies.

People who heat their homes with electricity — about 40 per cent of British Columbians —  have the highest overall bills in the province, $197 more in December than in July, when air conditioning use can affect energy costs.

This is the second year the Crown corporation has activated a cold-weather payment plan, part of broader customer assistance programs it offers.  

BC Hydro has also increased funding for its low-income conservation programs by $2.2 million for a total of $10 million over the next three years. 

The low-income program provides energy-saving kits that include things like free energy assessments, insulation upgrades and weather stripping.

Bruce nuclear reactor taken offline as $2.1B project 'officially' begins

Bruce Power Unit 6 refurbishment replaces major reactor components, shifting supply to hydroelectric and natural gas, sustaining Ontario jobs, extending plant life to 2064, and managing radioactive waste along Lake Huron, on-time and on-budget.

 

Key Points

A 4-year, $2.1B reactor overhaul within a 13-year, $13B program to extend plant life to 2064 and support Ontario jobs.

✅ Unit 6 offline 4 years; capacity shift to hydro and gas

✅ Part of 13-year, $13B program; extends life to 2064

✅ Creates jobs; manages radioactive waste at Lake Huron

 

The world’s largest nuclear fleet, became a little smaller Monday morning. Bruce Power has began the process to take Unit 6 offline to begin a $2.1 billion project, supported by manufacturing contracts with key suppliers, to replace all the major components of the reactor.

The reactor, which produces enough electricity to power 750,000 homes and reflects higher output after upgrades across the site, will be out of service for the next four years.

In its place, hydroelectric power and natural gas will be utilized more.

Taking Unit 6 offline is just the “official” beginning of a 13-year, $13-billion project to refurbish six of Bruce Power’s eight nuclear reactors, as Ontario advances the Pickering B refurbishment as well on its grid.

Work to extend the life of the nuclear plant started in 2016, and the company recently marked an operating record while supporting pandemic response, but the longest and hardest part of the project - the major component replacement - begins now.

“The Unit 6 project marks the next big step in a long campaign to revitalize this site,” says Mike Rencheck, Bruce Power’s president and CEO.

The overall project is expected to last until 2033, and mirrors life extensions at Pickering supporting Ontario’s zero-carbon goals, but will extend the life of the nuclear plant until 2064.

Extending the life of the Bruce Power nuclear plant will sustain 22,000 jobs in Ontario and add $4 billion a year in economic activity to the province, say Bruce Power officials.

About 2,000 skilled tradespeople will be required for each of the six reactor refurbishments - 4,200 people already work at the sprawling nuclear plant near Kincardine.

It will also mean tons of radioactive nuclear waste will be created that is currently stored in buildings on the Bruce Power site, along the shores of Lake Huron.

Bruce Power restarted two reactors back in 2012, and in later years doubled a PPE donation to support regional health partners. That project was $2-billion over-budget, and three years behind schedule.

Bruce Power officials say this refurbishment project is currently on-time and on-budget.

Idaho Power Settlement Could Close Coal Plant, Raise Rates

Idaho Power Valmy Settlement outlines early closure of the North Valmy coal-fired plant in Nevada, accelerated depreciation recovery, a 1.17% base-rate increase, and impacts for customers, NV Energy co-ownership, and Idaho Public Utilities Commission review.

 

Key Points

A proposed agreement to close North Valmy early, recover costs via a 1.17% rate hike, and seek PUC approval.

✅ Unit 1 closes 2019; Unit 2 closes 2025 in Nevada.

✅ 1.17% base-rate hike; about $1.20 per 1,000 kWh monthly bill.

✅ Idaho PUC comment deadline May 25; NV Energy co-owner.

 

State regulators have set a May 25 deadline for public comment on a proposed settlement related to the early closure of a coal-fired plant co-owned by Idaho Power, even as some utilities plan to keep a U.S. coal plant running indefinitely in other jurisdictions.

The settlement calls for shuttering Unit 1 of the North Valmy Power Plant in Nevada in 2019, with Unit 2 closing in 2025, amid regional coal unit retirements debates. The units had been slated for closure in 2031 and 2035, respectively.

If approved by the Idaho Public Utilities Commission, the settlement would increase base rates by approximately $13.3 million, or 1.17 percent, in order to allow the company to recover its investment in the plant on an accelerated basis.

That equates to an additional $1.20 on the monthly bill of the typical residential customer using 1,000 kilowatt-hours of energy per month.

Idaho Power, which co-owns the plant with NV Energy, maintains that closing Valmy early rather than continuing to operate it until it is fully depreciated in 2035, will ultimately save customers $103 million in today's dollars.

The company said a significant decrease in market prices for electricity has made it uneconomic to operate the plant except during extremely cold or hot weather, when the demand for energy peaks, a trend underscored by transactions involving the San Juan Generating Station deal elsewhere. The company also said plant balances have increased by approximately $70 million since its last general rate case in 2011, due to routine maintenance and repairs, as well as investments required to meet environmental regulations.

The proposed settlement reflects a number of changes to Idaho Power's original proposal regarding Valmy, and comes in the wake of discussions with interested parties in February and April, against the backdrop of a broader energy debate over plant closures and reliability.

In its initial application, filed in October, Idaho Power proposed closing both units in 2025. The original proposal would have increased base rates by $28.5 million, or about 2.5 percent, in order to allow the company to recover its costs associated with the plant's accelerated depreciation, decommissioning and anticipated investments, with cautionary examples such as the Kemper power plant costs illustrating potential risks.

Concurrently, Idaho Power asked for commission approval to adjust depreciation rates for its other plants and equipment based on the result of a study it conducts every five years, as outlined in Case IPC-E-16-23. The adjustment would have led to a $6.7 million increase to base rates.

The two requests filed in October would have increased customer costs by a total of $35.2 million or 3.1 percent, leading to a $3.08 increase on the bills of the typical residential customer who uses 1,000 kilowatt-hours per month.

The proposed settlement submitted to the Commission on May 4 calls for $13,285,285 to be recovered from all customer classes through base rates until 2028, all related to the Valmy shutdown. That is an increase of 1.17 percent and would result in a $1.20 increase on the bills of the typical residential customer who uses 1,000 kilowatt-hours per month.

First US coal plant in years opens where no options exist

Alaska Coal-Fired CHP Plant opens near Usibelli mine, supplying electricity and district heat to UAF; remote location without gas pipelines, low wind and solar potential, and high heating demand shaped fuel choice.

 

Key Points

A 17 MW coal CHP at UAF producing power and campus heat, chosen for remoteness and lack of gas pipelines.

✅ 17 MW generator supplying electricity and district heat

✅ Near Usibelli mine; limited pipeline access shapes fuel

✅ Alternative options like LNG, wind, solar not cost-effective

 

One way to boost coal in the US: Find a spot near a mine with no access to oil or natural gas pipelines, where it’s not particularly windy and it’s dark much of the year.

That’s how the first coal-fired plant to open in the U.S. since 2015 bucked the trend in an industry that’s seen scores of facilities close in recent years. A 17-megawatt generator, built for $245 million, is set to open in April at the University of Alaska Fairbanks, just 100 miles from the state’s only coal mine.

“Geography really drove what options are available to us,” said Kari Burrell, the university’s vice chancellor for administrative services, in an interview. “We are not saying this is ideal by any means.”

The new plant is arriving as coal fuels about 25 percent of electrical generation in the U.S., down from 45 percent a decade earlier, even as some forecasts point to a near-term increase in coal-fired generation in 2021. A near-record 18 coal plants closed in 2018, and 14 more are expected to follow this year, according to BloombergNEF.

The biggest bright spot for U.S. coal miners recently has been exports to overseas power plants. At home, one of the few growth areas has been in pizza ovens.

There are a handful of other U.S. coal power projects that have been proposed, including plans to build an 850 megawatt facility in Georgia and an 895 megawatt plant in Kansas, even as a Minnesota utility reports declining coal returns across parts of its portfolio. But Ashley Burke, a spokeswoman for the National Mining Association, said she’s unaware of any U.S. plants actively under development besides the one in Alaska.

 

Future of power

“The future of power in the U.S. does not include coal,” Tessie Petion, an analyst for HSBC Holdings Plc, said in a research note, a view echoed by regions such as Alberta retiring coal power early in their transition.

Fairbanks sits on the banks of the Chena River, amid the vast subarctic forests in the heart of Alaska. The oil and gas fields of the state’s North slope are 500 miles north. The nearest major port is in Anchorage, 350 miles south.

The university’s new plant is a combined heat and power generator, which will create steam both to generate electricity and heat campus buildings. Before opting for coal, the school looked into using liquid natural gas, wind and solar, bio-mass and a host of other options, as new projects in Southeast Alaska seek lower electricity costs across the region. None of them penciled out, said Mike Ruckhaus, a senior project manager at the university.

The project, financed with university and state-municipal bonds, replaces a coal plant that went into service in 1964. University spokeswoman Marmian Grimes said it’s worth noting that the new plant will emit fewer emissions.

The coal will come from Usibelli Coal Mine Inc., a family-owned business that produces between 1.2 and 2 million tons per year from a mine along the Alaska railroad, according to the company’s website.

While any new plant is good news for coal miners, Clarksons Platou Securities Inc. analyst Jeremy Sussman said this one is "an isolated situation."

“We think the best producers can hope for domestically is a slow down in plant closures,” he said, even as jurisdictions like Alberta close their last coal plant entirely.

Six key trends that shaped Europe's electricity markets in 2020

European Electricity Market Trends 2020 highlight decarbonisation, rising renewables, EV adoption, shifting energy mix, COVID-19 impacts, fuel switching, hydro, wind and solar growth, gas price dynamics, and wholesale electricity price increases.

 

Key Points

EU power in 2020 saw lower emissions, more renewables, EV growth, demand shifts, and higher wholesale prices.

✅ Power sector CO2 down 14% on higher renewables, lower coal

✅ Renewables 39% vs fossil 36%; hydro, wind, solar expanded

✅ EV share hit 17%; wholesale prices rose with gas, ETS costs

 

According to the Market Observatory for Energy DG Energy report, the COVID-19 pandemic and favorable weather conditions are the two key drivers of the trends experienced within the European electricity market in 2020. However, the two drivers were exceptional or seasonal.

The key trends within Europe’s electricity market include:


1. Decrease in power sector’s carbon emissions

As a result of the increase in renewables generation and decrease in fossil-fueled power generation in 2020, the power sector was able to reduce its carbon footprint by 14% in 2020. The decrease in the sector’s carbon footprint in 2020 is similar to trends witnessed in 2019 when fuel switching was the main factor behind the decarbonisation trend.

However, most of the drivers in 2020 were exceptional or seasonal (the pandemic, warm winter, high
hydro generation). However, the opposite is expected in 2021, with the first months of 2021 having relatively cold weather, lower wind speeds and higher gas prices, with stunted hydro and nuclear output also cited, developments which suggest that the carbon emissions and intensity of the power sector could rise.

The European Union is targeting to completely decarbonise its power sector by 2050 through the introduction of supporting policies such as the EU Emissions Trading Scheme, the Renewable Energy Directive and legislation addressing air pollutant emissions from industrial installations, with expectations that low-emissions sources will cover most demand growth in the coming years.

According to the European Environment Agency, Europe halved its power sector’s carbon emissions in 2019 from 1990 levels.


2. Changes in energy consumption

EU consumption of electricity fell by -4% as majority of industries did not operate at full level during the first half of 2020. Although majority of EU residents stayed at home, meaning an increase in residential energy use, rising demand by households could not reverse falls in other sectors of the economy.

However, as countries renewed COVID-19 restrictions, energy consumption during the 4th quarter was closer to the “normal levels” than in the first three quarters of 2020. 

The increase in energy consumption in the fourth quarter of 2020 was also partly due to colder temperatures compared to 2019 and signs of surging electricity demand in global markets.


3. Increase in demand for EVs

As the electrification of the transport system intensifies, the demand for electric vehicles increased in 2020 with almost half a million new registrations in the fourth quarter of 2020. This was the highest figure on record and translated into an unprecedented 17% market share, more than two times higher than in China and six times higher than in the United States.

However, the European Environment Agency (EEA)argues that the EV registrations were lower in 2020 compared to 2019. EEA states that in 2019, electric car registrations were close to 550 000 units, having reached 300 000 units in 2018.


4. Changes in the region’s energy mix and increase in renewable energy generation

The structure of the region’s energy mix changed in 2020, according to the report.

Owing to favorable weather conditions, hydro energy generation was very high and Europe was able to expand its portfolio of renewable energy generation such that renewables (39%) exceeded the share of fossil fuels (36%) for the first time ever in the EU energy mix.

Rising renewable generation was greatly assisted by 29 GW of wind and solar capacity additions in 2020, which is comparable to 2019 levels. Despite disrupting the supply chains of wind and solar resulting in project delays, the pandemic did not significantly slow down renewables’ expansion.

In fact, coal and lignite energy generation fell by 22% (-87 TWh) and nuclear output dropped by 11% (-79 TWh). On the other hand, gas energy generation was not significantly impacted owing to favorable prices which intensified coal-to-gas and lignite-to-gas switching, even as renewables crowd out gas in parts of the market.


5. Retirement of coal energy generation intensify

 As the outlook for emission-intensive technologies worsens and carbon prices rise, more and more early coal retirements have been announced. Utilities in Europe are expected to continue transitioning from coal energy generation under efforts to meet stringent carbon emissions reduction targets and as they try to prepare themselves for future business models that they anticipate to be entirely low-carbon reliant.

6. Increase in wholesale electricity prices

In recent months, more expensive emission allowances, along with rising gas prices, have driven up wholesale electricity prices on many European markets to levels last seen at the beginning of 2019. The effect was most pronounced in countries that are dependent on coal and lignite. The wholesale electricity prices dynamic is expected to filter through to retail prices.

The rapid sales growth in the EVs sector was accompanied by expanding charging infrastructure. The number of high-power charging points per 100 km of highways rose from 12 to 20 in 2020.
