Energy Storage Corporate Funding 2019 - 2023

“Energy storage companies saw their highest VC funding in 2023, largely thanks to the Inflation Reduction Act’s Investment Tax Credit and other incentives like manufacturing credits for battery components. Despite this positive trend, M&A activity lagged due to high asset valuations, elevated interest rates, and investor caution,” said Raj Prabhu, CEO of Mercom Capital Group.
