Flow Batteries and the Future of Grid-scale Energy Storage
We assess how de-risking supply chains, enhancing electrolyte designs, and leveraging membrane-less architectures will make flow batteries the most viable solution for
Flow batteries operate distinctively from “solid” batteries (e.g., lead and lithium) in that a flow battery's energy is stored in the liquid electrolytes that are pumped through the battery system (see image above) while a solid-state battery stores its energy in solid electrodes. There are several components that make up a flow battery system:
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.
Allegro's redox flow battery offers higher energy density and adapts to any environment. Luquos Energy is a Chinese startup that develops scalable flow battery technology for energy storage. The startup's aqueous electrolyte and earth-abundant elements store and provide renewable energy on demand.
At that level of performance, flow batteries could store enough renewable energy to provide large energy consumers, such as data centers, with a reliable source of electricity to smooth out bumps in renewable energy availability. There being no such thing as a free lunch, getting flow battery technology up to speed has been a long slog.
