Meet 20 Flow Battery Startups to Watch in 2025
Discover 20 emerging flow battery startups to watch in 2025 & find out how their solutions will impact your business!
Flow batteries, with their ability to create a more stable grid and reduce grid congestion, are considered a promising technology for energy storage. Their adoption is closely linked with the surging energy storage market and can help fill renewable energy production shortfalls.
Flow batteries help create a more stable grid and reduce grid congestion and fill renewable energy production shortfalls for asset owners. Global R&D is fueling the development of flow battery chemistry by significantly enabling higher energy density electrodes and also extending flow battery applications.
Typical flow battery chemistries include all vanadium, iron-chromium, zinc-bromine, zinc-cerium, and zinc-ion. A flow battery is an electrochemical cell that converts chemical energy into electrical energy as a result of ion exchange across an ion-selective membrane that separates two liquid electrolytes stored in separate tanks.
Based on the heat map, we see high startup activity in the USA, followed by the UK and Germany. These flow battery startups work on solutions ranging from grid-scale energy storage and novel battery materials to battery recycling and organic flow batteries.
