Carbon Brief has estimated that the United Kingdom would have needed to import 20 TWh less natural gas this year if successive Conservative governments had not wound down the rewards for generating solar electricity.

Ulsan National Institute of Science and Technology researchers have unveiled designs for advanced solar hydrogen production systems to broaden the application of LC biomass. Mitsubishi has started building the world’s first validation center for hydrogen-related technologies, while Fortescue Future Industries has announced investments in Germany and Australia.

Energy Vault’s EVx storage system is comparable to pumped hydro, using grid-scale renewable energy when supply is abundant to drive motors and raise 30-ton blocks on a six-arm crane tower, rather than water, up to a height. When power needs to be discharged back to the grid, the blocks are lowered, harvesting the kinetic energy.

Researchers at the University of Leicester have developed a new method of extracting silver and aluminum from end-of-life PV cells using iron chloride and aluminum chloride dissolved in brines. According to them, the cheap solvents retrieve up to 95% of the metals within 10 minutes, achieving a 98% purity of silver chloride.

SolarBotanic Trees will begin offering its solar trees in early 2023. The systems will use monocrystalline cells with an efficiency of up to 24%, encapsulated in a 3D shape.

SunHydrogen has provided a first look at the prototype design for its forthcoming nanoparticle-based green hydrogen technology, and Plug Power has secured a 5 MW electrolyzer order from Lhyfe. A Chinese-US research group, meanwhile, claims to have achieved a highly stable saline water electrolysis using Rhodium nanocrystals.

The local authority in Thurrock, England, has had control of its financial decisions passed to neighboring Essex County Council after racking up debts of more than GBP 1 billion ($1.1 billion) over four years, including more than GBP 800 million invested in solar bonds.

Solar Energy UK members have made positive noises about a plan to shift historic, fixed-payment incentive contracts over to contracts-for-difference deals, which would limit the profits they would receive from soaring energy prices.

Japanese researchers have developed a new way to improve water splitting, while South Korea has completed its largest hydrogen production complex. Scotland and England have announced new hydrogen investments, and Uzbekistan and Saudi Arabia’s ACWA Power have agreed to collaborate on hydrogen projects.

Researchers at the University of Cambridge have examined one of the fastest-charging anode materials by using a low-cost, lab-based optical microscopy technique. Their findings showed that particle fracture, which can reduce the storage capacity of a battery, is more common with higher rates of delithiation and in longer particles.
