A large sheep farming company in Germany is seeking PV asset owners who will let its animals graze sustainably at solar project sites, in a move that could be a win-win situation for everyone.

Researchers led by Monash University have made a discovery that will dramatically reduce lithium-from-brine extraction times. The innovative breakthrough is as simple as a sieve.

Researchers in Italy extensively analyzed four different configurations of their proposed system to assess its potential, including under non-optimal, ‘off-design’ conditions and concluded that, for now, subsidies would still be required for the commercial production of synthetic natural gas.

Scientists in China claim to have identified a special cathode material that could be utilized in more stable potassium-ion storage systems. According to the group, this new material could enable the development of storage systems able to retain 94% of their capacity after 2000 cycles, with 0.003% capacity fade per cycle.

Chinese-Canadian module manufacturer Canadian Solar and Italy’s Manni Energy have sold five PV plants with a total generation capacity of 17 MW to Dutch independent power producer Sonnedix. The Sicilian projects are among Italy’s first operational unsubsidized PV facilities.

The country’s energy regulator published two papers this week to solicit public feedback on plans that Mineral Resources and Energy Minister Gwede Mantashe recently submitted for review. The first document relates to the tech-neutral procurement of 2 GW of short-term risk-mitigation capacity, which could see solar emerge as a winner due to its quick deployment times. The second paper is linked to the nation’s Integrated Resource Plan 2019, which aims for up to 6 GW of new large-scale solar by 2030, as well as an additional 6 GW of distributed-generation capacity.

U.S.-owned analyst Wood Mackenzie expects solar demand to decline but predicts the market will recover, with the prospects for the energy transition remaining intact.

The Swedish Energy Agency this week said solar power supplies will increase from 400 GWh in 2018 to 1.7 TWh in 2022. Total energy supply in the country is expected to decline from 551 TWh to 526 TWh in the 2019-22 period, due to the shutdown of several nuclear power plants.

US scientists claim to have discovered a membrane which could lead to cheaper large scale flow batteries. The material is an ion-selective, aqueous-compatible polymer with intrinsic microporosity known as AquaPIM and is said to have tunable thickness and high conductivity in aqueous electrolytes.

Total is building a 25 MW/25 MWh lithium-ion storage system in Mardyck, northern France. The oil giant plans to commission the facility by the end of the year.
