Coal is poised to rebound from a two-year slump as China buys more than it exports for the first time in history.

Power use in China, the world's biggest coal producer, is rising 13 percent annually; utilities are building plants at a record pace. The nation gets 78 percent of its electricity from coal, spurring imports from Australia, Indonesia and Vietnam.

"The coal sector in China has undergone a change," said Mark Mobius, who oversees $30 billion at Templeton Asset Management in Singapore. Mobius says Asian coal prices may surge 42 percent in five years, bolstering China Shenhua Energy, the biggest coal company, China Coal Energy and Yanzhou Coal Mining.

Rising prices for the biggest fossil fuel after oil would drive power costs higher from Tokyo to London and benefit the mining companies Xstrata, Rio Tinto Group and BHP Billiton. Consumers like Tokyo Electric Power and RWE of Germany will pay more, hurting profit.

Annual coal contract prices in Asia may surpass all-time highs in the next 12 months. Deutsche Bank analysts led by Peter Richardson in Melbourne predict $58 a metric ton next year and $59.50 in 2009, from about $55.50 for the year that started April 1. Goldman Sachs Group of New York expects $56 next year.

Coal last traded at $54.50 a ton for shipments from Newcastle, Australia, down 16 percent from a peak of $63.10 in June 2004, the McCloskey Group, a coal consulting company in Hampshire, England said.

Goldman Sachs forecasts that higher coal prices will cause a 22 percent gain in the shares of Xstrata, based in Zug, Switzerland, the world's largest exporter of coal used in power plants.

Costs for shipping bulk commodities already are rising because of coal. At Newcastle, Australia, the world's biggest coal-loading port, a record 71 vessels sit offshore waiting to load because producers can't fill the orders fast enough.

The Baltic Dry Index, the benchmark for commodity-shipping costs, has risen 26 percent this year to 5,553, following an 80 percent surge in 2006 on London's Baltic Exchange.

China, which mines more than twice as much coal as the United States, the next biggest producer, uses the fuel to generate 622 gigawatts of electricity. Plants built in China in the last year alone generate enough power to supply Britain.

Si Posen, an expert at the China Coal Information Institute, said the Chinese have never had to look outside the country for the fuel since 10,000 years ago at the time of the New Stone Age, or Neolithic Era.

"People in Shanxi, now the largest coal production base, have been burning coal as fuel since then," Posen said in a telephone interview from Beijing. "China had been self-sufficient since it started producing coal."

But the government's closure of unsafe and illegal mines that killed 5,986 workers in 2005, or more than 16 people every day, is adding to the pressure on coal prices. Regulators shut 5,931 pits in 2006 and plan another 4,861 shutdowns by year-end.

China's purchases of coal in January exceeded exports by 1.4 million tons, the first time that happened, data from the Beijing-based General Administration of Customs show. While the trend reversed in February, the impetus for imports to rise is unstoppable. By 2010, demand may reach 2.6 billion tons, 270 million tons more than last year's output, the government said.

"We have been forecasting that China's exports will fall, and it has come to that, even more rapidly than we expected," said Clyde Henderson, a coal analyst at Energy Economics in Sydney.

Any turnaround to net purchases this year would come three years sooner than predicted by the Australian Bureau of Agricultural and Resource Economics, the government forecaster in the world's second-biggest exporter of thermal coal. Among the buyers is Datang International Power Generation, the second-largest Chinese power producer with a Hong Kong stock-exchange listing.

"Coal imports will account for about 10 percent of our total demand," said Bai Fugui, fuel procurement manager at Beijing-based Datang.

Power bill cut for 22m Thailand houses

Thailand Covid-19 Electricity Bill Relief offers energy subsidies, tariff cuts, and free power for small meters, helping work-from-home users as authorities waive charges and discount kWh rates via EGAT, MEA, PEA for three months.

 

Key Points

Program waiving or cutting household electricity bills for 22 million homes in March-May, easing work-from-home costs.

? Free power for meters <= 5 amps; up to 10M homes

? Up to 800 kWh: pay February rate; above, 50% discount

? >3,000 kWh: 30% discount; program valid March-May

 

The Thailand cabinet has formally approved energy authorities' decision to either waive or cut electricity charges, similar to B.C. electricity relief measures, for 22 million households where people are working at home because of the coronavirus disease.

Energy Minister Sontirat Sontijirawong said after the cabinet meeting on Tuesday that the ministers acknowledged the step taken by from the Energy Regulatory Commission, the Electricity Generating Authority of Thailand, the Metropolitan Electricity Authority and the Provincial Electricity Authority and noted parallels with Ontario's COVID-19 hydro plan rolled out to support ratepayers.

The measure would be valid for three months, from March to May, and cover 22 million households. It would cost the state 23.68 billion baht in lost revenue, he said, a pattern also seen with Ontario rate reductions affecting provincial revenues.


"The measure reduces the electricity charges burden on households. It is the cost of living of the people who are working from home to support the government's control of Covid-19," Mr Sontirat said.

The business sector also wants similar assistance, echoing sentiments from Ontario manufacturers during recent price reduction efforts. He said their requests were being considered.

Free electricity is extended to households with a power meter of no more than 5 amps. Up to 10 million households are expected to benefit, although issues like electricity payment challenges in India highlight different market contexts.

For households with a power meter over 5 amps, if their consumption does not exceed 800 units (kilowat hours), they will pay as much as they did in their February bill. The amount over 800 units will be subject to a 50 per cent discount, while elsewhere B.C. commercial consumption has fallen sharply.

Large houses that consume more than 3,000 units will get a 30 per cent discount, at a time when BC Hydro demand is down 10%.

Tesla reduces Solar + home battery pricing following California blackouts

Tesla Solar and Powerwall Discount offers a ~10% installation price cut amid PG&E blackouts, helping California homeowners with solar panels, battery storage, and backup power, while supporting renewable energy and resilient Supercharger infrastructure.

 

Key Points

A ~10% installation discount on Tesla solar panels and Powerwall batteries to boost backup power during PG&E blackouts.

✅ ~10% off installation for solar plus Powerwall

✅ Helps during PG&E shutoffs and wildfire mitigation

✅ Supports resilience, backup power, and EV charging

 

Pacific Gas & Electric’s (PG&E) shutoff of electric supply to residents in California’s Bay Area has caught the attention of Tesla and SpaceX CEO Elon Musk, who, while highlighting a huge future for Tesla Energy in coming years, has announced that he would be offering a price reduction of approximately 10% for a solar panel and Tesla Powerwall battery installation. The discount will be available to anyone interested in powering their homes with solar energy, not just the 800,000 affected homes in the Bay Area.

After initially tweeting a link to Tesla’s Solar page on Tesla.com, Musk added that he would be offering a “~10% price reduction” in installation price for solar panels and Powerwall batteries for anyone, as California explores EVs for grid stability during emergencies, including those who have lost power in response to PG&E’s power shutoff. The blackout induced by the California-based power company is a part of an effort to reduce the possibility of wildfires. PG&E lines were the cause of multiple fires in the past, so the company is taking every necessary precaution to reduce the probability of its lines causing another fire in the future.

Tesla Solar recently offered a subscription program that would allow homeowners to lease panels for a fraction of the cost. The service is available to both residential and commercial customers, and costs as little as $45 a month in some states, particularly appealing in California where EV sales top 20% recently. The option to lease solar panels carries no long-term contracts that would tie down customers to a lengthy commitment.

Wildfires have always been an issue in California. Currently, fires are ripping through Los Angeles county, presumably caused by the winds of the Autumn season. The effort to reduce the environmental impact of forest fires in the state has been increasingly more prevalent over the years. But 2019 is a different story, underscoring that California may need a much bigger grid to support electrification, considering the previous year was noted as the deadliest wildfire season in California’s history. Over 8,500 fires destroyed over 1.89 million acres of land burned due to fires, causing the California Department of Forestry and Fire Protection to spend $432 million through the end of August 2018, according to the Associated Press.

In reaction to the news of the power shutoffs, Tesla added words of advice to vehicle affected owners on its app. The company posted a message encouraging drivers to keep their vehicles charged to 100% and highlighted that EVs can power homes for up to three days during outages, in order to prevent interruptions in driving. Those who are driving ICE vehicles are feeling the effects of the blackout too, as gas stations in California’s affected region have begun to shut down. Musk also tweeted that he would be installing Tesla Powerpacks at all Supercharger stations in the affected region, a move that can help ease strain on state power grids during outages, in order to allow owners to charge their vehicles.

In addition to the efforts that Tesla has already put into place, Musk plans to transition all Supercharger stations to solar power as soon as possible. But the sunny climate of California offers residents a great opportunity to move from gas and electric, even as some warn of a looming green car wreck in the state, to a more eco-friendly, sun-powered option. Tesla solar will completely eliminate power blackouts that are used to control wildfires in California.

Gulf Power to Provide One-Time Bill Decrease of 40%

Gulf Power 40% One-Time Bill Decrease approved by the Florida Public Service Commission delivers a May fuel credit and COVID-19 relief, cutting residential and business costs across rate classes while supporting budgeting and energy savings.

 

Key Points

PSC-approved fuel credit cutting May electric bills about 40% for homes and 40-55% for businesses as COVID-19 relief.

✅ One-time May fuel credit on customer bills

✅ Residential cut ~40%; business savings 40-55% by rate class

✅ Online tools show daily usage and projected bill

 

Gulf Power announced that the Florida Public Service Commission unanimously approved its request to issue a one-time decrease of approximately 40% for the typical residential customer bill beginning May 1, similar to recent Georgia Power bill reductions seen elsewhere. Business customers will also see a significant one-time decrease of approximately 40-55% in May, depending on usage and rate class.

"We are pleased that the Florida Public Service Commission has approved our request to deliver this savings to our customers when they need it most. We felt that this was the right thing to do, especially during times like these," said Gulf Power President Marlene Santos. "Our customers and communities now more than ever count on the reliable and affordable energy we deliver, and we are pleased that May bills will reflect this additional, significant savings for our customers."

In Florida, fuel savings are typically refunded to customers over the remainder of the year to provide level, predictable bills. However, given the emergent and significant financial challenges facing many customers due to COVID-19, Gulf Power instead sought approval to give customers the total annual savings in their May bill, similar to a lump-sum electricity credit approach, which will be reflected as a line-item fuel credit on their May statement.

New tools to help save energy and money

Many customers are working from home and, in general, staying at home more. More time and extra people in the home will likely increase power usage, which could lead to higher monthly bills.

Gulf Power recently added new tools to our customers' online account portal to help them better understand and manage their energy usage, including their monthly projected bill amount and a breakdown of daily energy usage, which is available for most residential customers*. Customers can now see their previous day's energy usage using their online account portal to help them more easily understand how their previous day's activities impacted energy usage, allowing them to quickly make adjustments to keep bills low. The new projected bill feature is a valuable tool to assist customers in budgeting for their next month's energy bill.

Additional energy-saving tips that can be implemented with no additional cost or equipment are also available. As always, Gulf Power's free online Energy Checkup tool will provide customers with a customized report based on their home's actual energy use.

Helping customers pay their bills

Gulf Power has a long history of working with its customers during difficult times, including periods of pandemic-related energy insecurity, and will continue to do so. Gulf Power encourages customers that are having difficulty paying their energy bill to visit GulfPower.com/help to view available resources that can provide assistance to qualifying customers.

Customers are encouraged to pay their electric bill balance each month to avoid building up a large balance, which they will continue to bear responsibility for. Gulf Power will work with the customer's personal situation and assist with a solution, similar to how utilities in Texas have waived fees during this period, to help customers fulfill their personal responsibility for their Gulf Power balance.

Those who can afford or want to help others who may need assistance with their energy bill can make a donation to Project SHARE in your online customer portal. Project SHARE donations are added to a customer's monthly bill and all contributions are distributed to local offices of The Salvation Army. Customers in need of utility bill assistance can apply for Project SHARE assistance at The Salvation Army office in their county.

Supporting our communities

The Gulf Power Foundation gave $500,000 to United Way organizations across Northwest Florida to assist those most vulnerable during this time, which has helped support food, housing and other essential needs throughout the region. In addition, the Foundation recently made a $10,000 donation to Feeding the Gulf Coast and launched an employee donation campaign to provide food for our neighbors in need, while Entergy emergency relief fund offers a similar example of industry support. In total, Gulf Power and its fellow NextEra Energy companies and employees have so far committed more than $4 million in COVID-19 emergency assistance funds that will be distributed directly to those in need and to partner organizations working on the frontlines of the crisis to provide critical support to the most vulnerable members of the community.

Lower fuel costs are enabling Gulf Power to issue a one-time decrease of approximately 40% for the typical residential customer bill in May, even as FPL faces a hurricane surcharge controversy in the state
- a significant savings amid the ongoing COVID-19 pandemic

Gulf Power will deliver savings to customers through a one-time bill decrease, rather than the standard practice of spreading out savings over the remainder of the year, even as FPL proposes multi-year rate hikes elsewhere

Current Model For Storing Nuclear Waste Is Incomplete

Nuclear Waste Corrosion accelerates as stainless steel, glass, and ceramics interact in aqueous conditions, driving localized corrosion in repositories like Yucca Mountain, according to Nature Materials research on high-level radioactive waste storage.

 

Key Points

Degradation of waste forms and canisters from water-driven chemistry, causing accelerated, localized corrosion in storage.

✅ Stainless steel-glass contact triggers severe localized attack

✅ Ceramics and steel co-corrosion observed under aqueous conditions

✅ Yucca Mountain-like chemistry accelerates waste form degradation

 

The materials the United States and other countries plan to use to store high-level nuclear waste, even as utilities expand carbon-free electricity portfolios, will likely degrade faster than anyone previously knew because of the way those materials interact, new research shows.

The findings, published today in the journal Nature Materials (https://www.nature.com/articles/s41563-019-0579-x), show that corrosion of nuclear waste storage materials accelerates because of changes in the chemistry of the nuclear waste solution, and because of the way the materials interact with one another.

"This indicates that the current models may not be sufficient to keep this waste safely stored," said Xiaolei Guo, lead author of the study and deputy director of Ohio State's Center for Performance and Design of Nuclear Waste Forms and Containers, part of the university's College of Engineering. "And it shows that we need to develop a new model for storing nuclear waste."

Beyond waste storage, options like carbon capture technologies are being explored to reduce atmospheric CO2 alongside nuclear energy.

The team's research focused on storage materials for high-level nuclear waste -- primarily defense waste, the legacy of past nuclear arms production. The waste is highly radioactive. While some types of the waste have half-lives of about 30 years, others -- for example, plutonium -- have a half-life that can be tens of thousands of years. The half-life of a radioactive element is the time needed for half of the material to decay.

The United States currently has no disposal site for that waste; according to the U.S. General Accountability Office, it is typically stored near the nuclear power plants where it is produced. A permanent site has been proposed for Yucca Mountain in Nevada, though plans have stalled. Countries around the world have debated the best way to deal with nuclear waste; only one, Finland, has started construction on a long-term repository for high-level nuclear waste.

But the long-term plan for high-level defense waste disposal and storage around the globe is largely the same, even as the U.S. works to sustain nuclear power for decarbonization efforts. It involves mixing the nuclear waste with other materials to form glass or ceramics, and then encasing those pieces of glass or ceramics -- now radioactive -- inside metallic canisters. The canisters then would be buried deep underground in a repository to isolate it.

At the generation level, regulators are advancing EPA power plant rules on carbon capture to curb emissions while nuclear waste strategies evolve.

In this study, the researchers found that when exposed to an aqueous environment, glass and ceramics interact with stainless steel to accelerate corrosion, especially of the glass and ceramic materials holding nuclear waste.

In parallel, the electrical grid's reliance on SF6 insulating gas has raised warming concerns across Europe.

The study qualitatively measured the difference between accelerated corrosion and natural corrosion of the storage materials. Guo called it "severe."

"In the real-life scenario, the glass or ceramic waste forms would be in close contact with stainless steel canisters. Under specific conditions, the corrosion of stainless steel will go crazy," he said. "It creates a super-aggressive environment that can corrode surrounding materials."

To analyze corrosion, the research team pressed glass or ceramic "waste forms" -- the shapes into which nuclear waste is encapsulated -- against stainless steel and immersed them in solutions for up to 30 days, under conditions that simulate those under Yucca Mountain, the proposed nuclear waste repository.

Those experiments showed that when glass and stainless steel were pressed against one another, stainless steel corrosion was "severe" and "localized," according to the study. The researchers also noted cracks and enhanced corrosion on the parts of the glass that had been in contact with stainless steel.

Part of the problem lies in the Periodic Table. Stainless steel is made primarily of iron mixed with other elements, including nickel and chromium. Iron has a chemical affinity for silicon, which is a key element of glass.

The experiments also showed that when ceramics -- another potential holder for nuclear waste -- were pressed against stainless steel under conditions that mimicked those beneath Yucca Mountain, both the ceramics and stainless steel corroded in a "severe localized" way.

Other Ohio State researchers involved in this study include Gopal Viswanathan, Tianshu Li and Gerald Frankel.

This work was funded in part by the U.S. Department of Energy Office of Science.

Meanwhile, U.S. monitoring shows potent greenhouse gas declines confirming the impact of control efforts across the energy sector.

Electricity turns garbage into graphene

Waste-to-Graphene uses flash joule heating to convert carbon-rich trash into turbostratic graphene for composites, asphalt, concrete, and flexible electronics, delivering scalable, low-cost, high-quality material from food scraps, plastics, and tires with minimal processing.

 

Key Points

A flash heating method converting waste carbon into turbostratic graphene for scalable, low-cost industrial uses.

✅ Converts food scraps, plastics, and tires into graphene

✅ Produces turbostratic flakes that disperse well in composites

✅ Scalable, low-cost process via flash joule heating

 

Science doesn’t usually take after fairy tales. But Rumpelstiltskin, the magical imp who spun straw into gold, would be impressed with the latest chemical wizardry. Researchers at Rice University report today in Nature that they can zap virtually any source of solid carbon, from food scraps to old car tires, and turn it into graphene—sheets of carbon atoms prized for applications ranging from high-strength plastic to flexible electronics, and debates over 5G electricity use continue to evolve. Current techniques yield tiny quantities of picture-perfect graphene or up to tons of less prized graphene chunks; the new method already produces grams per day of near-pristine graphene in the lab, and researchers are now scaling it up to kilograms per day.

“This work is pioneering from a scientific and practical standpoint” as it promises to make graphene cheap enough to use to strengthen asphalt or paint, says Ray Baughman, a chemist at the University of Texas, Dallas. “I wish I had thought of it.” The researchers have already founded a new startup company, Universal Matter, to commercialize their waste-to-graphene process, while others are digitizing the electrical system to modernize infrastructure.

With atom-thin sheets of carbon atoms arranged like chicken wire, graphene is stronger than steel, conducts electricity and heat better than copper, and can serve as an impermeable barrier preventing metals from rusting, while advances such as superconducting cables aim to cut grid losses. But since its 2004 discovery, high-quality graphene—either single sheets or just a few stacked layers—has remained expensive to make and purify on an industrial scale. That’s not a problem for making diminutive devices such as high-speed transistors and efficient light-emitting diodes. But current techniques, which make graphene by depositing it from a vapor, are too costly for many high-volume applications. And higher throughput approaches, such as peeling graphene from chunks of the mineral graphite, produce flecks composed of up to 50 graphene layers that are not ideal for most applications.

Graphene comes in many forms. Single sheets, which are ideal for electronics and optics, can be grown using a method called chemical vapor deposition. But it produces only tiny amounts. For large volumes, companies commonly use a technique called liquid exfoliation. They start with chunks of graphite, which is just myriad stacked graphene layers. Then they use acids and solvents, as well as mechanical grinding, to shear off flakes. This approach typically produces tiny platelets each made up of 20 to 50 layers of graphene.

In 2014, James Tour, a chemist at Rice, and his colleagues found they could make a pure form of graphene—each piece just a few layers thick—by zapping a form of amorphous carbon called carbon black with a laser. Brief pulses heated the carbon to more than 3000 kelvins, snapping the bonds between carbon atoms; for comparison, researchers have also generated electricity from falling snow using triboelectric effects. As the cloud of carbon cooled, it coalesced into the most stable structure possible, graphene. But the approach still produced only tiny qualities and required a lot of energy.

Two years ago, Luong Xuan Duy, one of Tour’s graduate students, read that other researchers had created metal nanoparticles by zapping a material with electricity, creating the same brief blast of heat behind the success of the laser graphene approach. “I wondered if I could use that to heat a carbon source and produce graphene,” Duy says. So, he put a dash of carbon black in a clear glass vial and zapped it with 400 volts, similar in spirit to electrical weed zapping approaches in agriculture, for about 200 milliseconds. Initially he got junk. But after a bit of tweaking, he managed to create a bright yellowish white flash, indicating the temperature inside the vial was reaching about 3000 kelvins. Chemical tests revealed he had produced graphene.

It turned out to be a type of graphene that is ideal for bulk uses. As the carbon atoms condense to form graphene, they don’t have time to stack in a regular pattern, as they do in graphite. The result is a material known as turbostatic graphene, with graphene layers jumbled at all angles atop one another. “That’s a good thing,” Duy says. When added to water or other solvents, turbostatic graphene remains suspended instead of clumping up, allowing each fleck of the material to interact with whatever composite it’s added to.

“This will make it a very good material for applications,” says Monica Craciun, a materials physicist at the University of Exeter. In 2018, she and her colleagues reported that adding graphene to concrete more than doubled its compressive strength. Tour’s team saw much the same result. When they added just 0.05% by weight of their flash-produced graphene to concrete, the compressive strength rose 25%; graphene added to polydimethylsiloxane, a common plastic, boosted its strength by 250%.

As digital control spreads across energy networks, research to counter ransomware-driven blackouts is increasingly important for grid resilience.

Those results could reignite efforts to use graphene in a wide range of composites. Researchers in Italy reported recently that adding graphene to asphalt dramatically reduces its tendency to fracture and more than doubles its life span. Last year, Iterchimica, an Italian company, began to test a 250-meter stretch of road in Milan paved with graphene-spiked asphalt. Tests elsewhere have shown that adding graphene to paint dramatically improves corrosion resistance.

These applications would require high-quality graphene by the ton. Fortunately, the starting point for flash graphene could hardly be cheaper or more abundant: Virtually any organic matter, including coffee grounds, food scraps, old tires, and plastic bottles, can be vaporized to make the material. “We’re turning garbage into graphene,” Duy says.

Electrifying: New cement makes concrete generate electricity

Cement-Based Conductive Composite transforms concrete into power by energy harvesting via triboelectric nanogenerator action, carbon fibers, and built-in capacitors, enabling net-zero buildings and self-sensing structural health monitoring from footsteps, wind, rain, and waves.

 

Key Points

A carbon fiber cement that harvests and stores energy as electricity, enabling net-zero, self-sensing concrete.

✅ Uses carbon fibers to create a conductive concrete matrix

✅ Acts as a triboelectric nanogenerator and capacitor

✅ Enables net-zero, self-sensing structural health monitoring

 

Engineers from South Korea have invented a cement-based composite that can be used in concrete to make structures that generate and store electricity through exposure to external mechanical energy sources like footsteps, wind, rain and waves, and even self-powering roads concepts.

By turning structures into power sources, the cement will crack the problem of the built environment consuming 40% of the world’s energy, complementing vehicle-to-building energy strategies across the sector, they believe.

Building users need not worry about getting electrocuted. Tests showed that a 1% volume of conductive carbon fibres in a cement mixture was enough to give the cement the desired electrical properties without compromising structural performance, complementing grid-scale vanadium flow batteries in the broader storage landscape, and the current generated was far lower than the maximum allowable level for the human body.

Researchers in mechanical and civil engineering from from Incheon National University, Kyung Hee University and Korea University developed a cement-based conductive composite (CBC) with carbon fibres that can also act as a triboelectric nanogenerator (TENG), a type of mechanical energy harvester.

They designed a lab-scale structure and a CBC-based capacitor using the developed material to test its energy harvesting and storage capabilities, similar in ambition to gravity storage approaches being scaled.

“We wanted to develop a structural energy material that could be used to build net-zero energy structures that use and produce their own electricity,” said Seung-Jung Lee, a professor in Incheon National University’s Department of Civil and Environmental Engineering, noting parallels with low-income housing microgrids in urban settings.

“Since cement is an indispensable construction material, we decided to use it with conductive fillers as the core conductive element for our CBC-TENG system,” he added.

The results of their research were published this month in the journal Nano Energy.

Apart from energy storage and harvesting, the material could also be used to design self-sensing systems that monitor the structural health and predict the remaining service life of concrete structures without any external power, which is valuable in industrial settings where hydrogen-powered port equipment is being deployed.

“Our ultimate goal was to develop materials that made the lives of people better and did not need any extra energy to save the planet. And we expect that the findings from this study can be used to expand the applicability of CBC as an all-in-one energy material for net-zero energy structures,” said Prof. Lee, pointing to emerging circular battery recycling pathways for net-zero supply chains.

Publicising the research, Incheon National University quipped: “Seems like a jolting start to a brighter and greener tomorrow!”
