Number of grid technology start-ups founded, 2010-2025

Sources

IEA analysis based on data from Cleantech Group (2025) and Crunchbase (2025).

Notes

Numbers of start-ups founded in 2024 and 2025 are underestimates as many start-ups only become publicly known once they have existed for 2 or more years and raised initial funds. For battery-related funding amounts, only budgets estimated to be allocated to stationary storage applications are included, but for the estimation of the number of start-ups, more battery start-ups are considered (including start-ups with intellectual property related to electric vehicle batteries).
