At a grid-scale energy storage panel at Intersolar North America, industry leaders pointed to international storage project case studies that could be replicated in the U.S.

Researchers led by the University of Rochester claim to have increased the photoresponsivity of a lead-halide perovskite for solar cell applications by 250%. They created a perovskite film with a plasmonic substrate made of hyperbolic metamaterial and characterized it with transition dipole orientation.

The Smart Electric Power Alliance survey reports utilities’ progress on actions that can support the deployment of solar, wind and storage.

U.S. researchers have designed a molten salt battery that uses an aluminum cathode that charges quickly and reportedly enables longer-duration discharge.

Also on the rise: World’s largest used EV battery power facility in California. Enel adds 2 GW of North America renewable capacity in 2022. And more.

The partnership between AutoGrid and SWTCH Energy marks the first demand response program in North America to incorporate EV chargers in multi-unit residential buildings

“Lights On California” believes it’s time for California to consider clean energy solutions both within and beyond its borders to prevent blackouts, reduce energy costs, and transition to 100% clean energy.

Texas grid operator ERCOT advanced interconnection requests for 15 GW of solar projects last year, with three other grid operators advancing 9 GW. CAISO completed phase 1 studies for a large cluster of projects, while PJM and ISO-NE stayed mum on their progress.

With increasing adoption of electric vehicles and heat pumps, whose demand can be flexible, “marrying” that trend with the upward trend of variable renewable generation “could accelerate both,” said a paper from the Energy Systems Integration Group.

The solar plus lithium-ion battery microgrid provides power to the Appalachian town during a black start, which during a power outage allows for a full repowering without the use of the local grid.
