The US Energy Department set a goal of achieving 2 cents/kWh by 2030, and announced an initial $128 million in funding to support technology development.
Heliogen, which was founded by serial entrepreneur Bill Gross, aims to revitalize concentrated solar power with sCO2 tech to cut costs, water use, and plant footprints in industrial applications not suited to solar PV.
Recovering silicon of the quality required for reuse in panels is at the heart of mitigating device carbon footprints. R&D efforts should be ramped up now, says an international research group, so the technology is in place when huge volumes of modules begin to need replacing.
Plus, one Australian installer says residents who had installed solar and storage at home will be cushioned against thumping, coronavirus-related electricity bill rises this quarter and there are signs of recovery in overall energy consumption levels.
The road to cheap hydrogen production is riddled with potholes and energy losses. Researchers in Australia have demonstrated rethinking solar technology and skipping electrolysers could hold great promise for reaching the hydrogen holy grail.
Researchers in the U.S. have demonstrated, using simulations, PV system generation can range from 18-60% of clear-sky potential during hurricanes – provided the arrays do not suffer damage. According to them, solar installations could continue to provide back-up power when grids are down during hurricanes, especially if coupled with energy storage.
MIT scientists have suggested used electric vehicle batteries could offer a more viable business case than purpose-built systems for the storage of grid scale solar power in California. Such ‘second life’ EV batteries, may cost only 60% of their original purchase price to deploy and can be effectively aggregated for industrial scale storage even if they have declined to 80% of their original capacity.
Cell supply shortages could kick-start manufacturing activity in India, EV car sales are braced for a fall while still gaining market share and a new date has been set for the world’s biggest solar trade show.
The material was used by scientists in the U.S. in electrochemical cells which use electricity to separate steam into hydrogen and oxygen. The researchers say the oxide of perovskite used in the electrode improves cell performance and reduces operating temperatures.
