Italy should embrace solar, not gas to hit raised climate ambition

Instead of splurging €11 billion of EU cash on uneconomic new generation capacity, the Italian authorities–and electricity bill payers–would be better served investing in a mix of current clean power technologies which would include almost 17 GW more solar capacity.

Silicon for batteries moves to commercial production

U.S. company Group14 Technologies today announced the launch of a factory capable of producing 120 tons per year of its innovative silicon-carbon-based anode material for lithium-ion batteries. The factory is located at Group14’s headquarters in Woodinville, Washington and is the first of several planned by the company.

Solar power has to be about quality as well as quantity

Greater dispatchability will be required from solar as it becomes increasingly mainstream worldwide, or investors could experience diminishing returns as a victim of the technology’s success at bearing down on electricity prices.

Solar-plus-storage signaled by Xinyi internal sales

Lithium-ion battery products will be sold by the group’s storage and autoglass business to its solar glass operation–for use in solar project development–and its float glass manufacturing unit.

Nickel-salen for a battery that charges in 10 seconds

Scientists in Russia introduce a promising new material for battery energy storage, the product of more than three years of research. Incorporating a nickel-salen polymer into the cathode, the group demonstrated a battery that can charge and discharge ten times faster than today’s lithium-ion batteries. And though the battery still lags in terms of overall capacity, the group is confident that its discovery will lead to big improvements for lithium batteries.

Chinese PV Industry Brief: Longi expands into hydrogen, Eging PV secures 280 MW order

Monocrystalline module manufacturer Longi is venturing into new territory but missed out to its rival on two big panel orders from a state-owned power company.

Greece’s recovery plan to invest €10bn in clean energy

The Greek government has published its plan for a post-Covid economic recovery. The strategy aims to mobilize at least €10 billion towards the green energy sector, with the prospect of further EU loans on top.

What will African nations require to produce competitive green hydrogen exports?

A robust national strategy, a portfolio of renewable energy assets, public subsidies and, ideally, existing gas pipelines will all favor African nations aiming to become exporters in the energy storage medium, participants heard at a recent two-day green hydrogen conference.

African green hydrogen could feed German and Japanese industry and water drought-stricken nations

Trade bodies the Africa Solar Industry Association and the African Hydrogen Partnership hosted a two-day virtual conference to discuss the role green hydrogen can play in economic growth across the continent–and how it could drive desalination in freshwater-starved coastal countries.

Battery costs have fallen 97% since 1991, claim MIT researchers

Academics reviewed the historic price development of lithium-ion batteries and found the accepted model does not accurately reflect the full cost decline and technological improvement which has taken place. With more data points to compare, the team found batteries had improved even more than previously assumed.
