Vanadium redox flow storage is best suited for applications with both high power and high capacity requirements, explains Bengt Stahlschmidt, Head of Sales CellCube at Gildemeister energy solutions, in an Engerati interview at European Utility Week 2014.
The reason is that with this technology the power and capacity are “separated”, enabling the two functions to be scaled independently, rather than dependently as with for example certain battery technologies, Stahlschmidt explains.
Other advantages he adds include unlimited cycling and absence of moving parts (except pumps) providing longevity in the field.
Vanadium redox flow storage is also suitable for both grid-connected and microgrid applications.
“We can build multi-MW systems with high capacity that can be used for grid stabilization and deferral of renewable power use. In a microgrid the solution can be used for diesel substitution to reduce the runtime of a diesel genset,” says Stahlschmidt.
From an operational perspective, the technology is also straightforward to install. It comes as a complete containerized solution including the storage system, management application and housing, and requires a location that can accommodate its weight.
