PV goes portable
Portable solar generators are making their way from the fringes of solar and energy storage to become a mainstream consumer item. The rise has been charged by a range of factors that have created massive brands. Where did the sector emerge from, who was buying before, who is buying now, and what’s next? Tristan Rayner reports.
Innovations in long-duration energy storage
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.
Leading solar inverter trends of 2022
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.
US battery startup to produce solid-state batteries with bi-layer cell design
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 sells Maxwell Technologies but keeps its dry cell tech for lithium-ion batteries
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.
UK government launches competition to spur long-duration energy storage innovation
