The Regulatory Assistance Project, a global NGO, has proposed a mix of policy recommendations to build confidence in heat pump technology. Its proposed policies include economic incentives, new regulations, R&D support, training, and promotional initiatives.

Scientists in China have studied the impact of shading on single solar cells and on simple arrangements of two cells connected in series or in parallel.

Toshiba has revealed that it has improved the power conversion efficiency of a transparent cuprous oxide solar cell to 9.5%, from the 8.4% mark it reached in December 2021. It enlarged the cell and suppressed carrier recombination at the edge of the cuprous oxide (Cu2O) generation layer, which usually causes generation efficiency degradation.

US researchers have discovered an appropriate solvent design for the application of a 2D top layer on a perovskite solar cell. The cells incorporate the stability of 2D perovskite cells and the efficiency of 3D cells without destroying the 3D bottom layer, which brings them closer to commercialization.

Verdagy has reported a levelized cost of green hydrogen (LCOH) below $3.00/kg for its anion exchange membrane (AEM). The California-based company said it can now launch commercial operations.

Marsh has launched the world’s first insurance facility for green and blue hydrogen project risks. pv magazine recently spoke with the company about the challenges that operators face in securing insurance coverage for new technologies.

The Inflation Reduction Act (IRA), signed into law by US President Joe Biden, represents the single largest investment in clean energy, GHG emissions reduction, and climate resilience in the country’s history by providing around US$370 billion for green energy tax credits and other incentives to spur large-scale development of solar energy technologies to electrify the US’s digitization.

Germany made efforts this week to expand hydrogen ties with the Gulf states, and Japan announced plans to team up with several nations to ramp up hydrogen production. ICIS, meanwhile, has started offering Europe’s first market-linked renewable hydrogen assessments.

US researchers say they have developed a way to make cobalt-free lithium-ion battery cathodes, while Ford says it has broken ground on a new $5.6 billion production complex for electric vehicles and batteries.

The 2.7 million people employed in solar in China last year dwarfed the 250,000 working in the US solar industry, according to a new report by the International Renewable Energy Agency.
