Long-duration energy storage (LDES) is essential for decarbonizing the grid but gigawatt-hour scale systems continue to be tricky for companies with big ideas.

It was a good year for the inverter market. Strong demand was only stifled by supply chain limits, but new inverters are less innovative and show a slower evolution in improvements. Nevertheless, more versatile options are emerging in response to the energy crisis.

Ion Storage System’s $30 million capital raising will go toward scaling up its solid-state battery cell production facility in Maryland, with aims to produce 10 MWh per year by the end of 2023, for a range of applications.

Tesla acquired the supercapacitor maker in 2019, but has since moved on and sold the unit to UCAP-Power, while keeping the company’s dry electrode tech.
