Vestas goes with the flow
Orbats initiative developing up to 25kW fluid-based battery storage demo
Vestas is part of a team working on the development of so-called flow batteries to help connect more fluctuating renewable energy to the grid.
The Danish manufacturer together with DTU Energy, VisBlue, Aarhus University, Lithium Balance and Harvard University are working on flow battery solutions, which store energy in fluid outside of the battery.
“If you need more capacity, you can only purchase a larger storage tank and pour more fluid without having to make the battery bigger,” the group known as Orbats said.
They added that traditional batteries use expensive vanadium compounds, while Orbats aims to use “sustainable organic materials” instead.
The project will produce a demonstration prototype of between 5kW and 25kW, as well as a strategy to optimise the battery performance.
Vestas chief technology officer Anders Vedel said: “We see great potential in efficient battery technology, as a step towards a fully sustainable energy supply.”
