An international group of researchers has demonstrated an aqueous zinc battery with excellent performance in terms of capacity, rate capability, specific energy, and output voltage. The supercapacitor-battery hybrid device has also shown unprecedented cycling stability 99.2% capacity retention after 17,000 cycles at 100% depth of discharge.

Enel Green Power’s new solar panel has average efficiencies ranging from 22.6% to 22.9% and a temperature coefficient of -0.24% per degree Celsius. It is based on an n-type solar cell with G12 format and a power conversion efficiency of 24.6%.

A recent report by the International Energy Agency Photovoltaic Power Systems Programme (IEA PVSP) reviews the current regulatory and industrial landscape for end-of-life PV management in Germany, France, Italy, Spain, Japan, South Korea, China, Australia, and the United States.

Electric planes might seem futuristic, but they aren’t that far off, at least for short hops. Two-seater Velis Electros are already quietly buzzing around Europe, electric sea planes are being tested in British Columbia, and larger planes are coming.

A new report published by the International Energy Agency shows solar PV provided employment for approximately 3.4 million people in 2021 with almost half of the workers employed in China, about 280,000 in North America, over 260,000 in Europe, and some 50,000 in Africa. The vast majority of workers were employed in manufacturing and installation of new capacity, with solar jobs paying lower wage premiums than the nuclear, oil, and gas industries.

Ukraine is still facing dire circumstances, with war continuing to claim lives and Russian invaders occupying large parts of the country. Solar plant owners also face serious challenges, including collateral damage, looting, destruction of communication infrastructure, and payment shortfalls. However, a bold vision for recovery has been set out with a key role for solar, as Ian Skarytovsky reports.

Transitioning from fossil fuels to renewable energy technologies including solar PV and green hydrogen by 2050 could save the world at least $18 trillion (US$12 trillion), according to a peer-reviewed study published by researchers from Britain’s Oxford University and Australia’s Monash University.

Crypto mining electricity use can exceed that of large, developed nations. Solar and storage can help cut carbon impact, but could the power be best used elsewhere?

Scientists compared hydrogen storage techniques and found that physical methods are closer to commercial feasibility, while materials-based techniques have strong potential.

US researchers have developed a new solid-state lithium-metal battery, and China’s SVOLT has started producing prototype solid-state cells. Toyota, meanwhile, has revealed plans to invest billions of dollars in battery production.
