Study: flow batteries beat lithium ion

Flow batteries, such as this ESS All-Iron unit under contract to the US Army Corps of Engineers, have the potential to reach commercial cost-effectiveness before lithium-ion, new research shows. Pic: ESS.

UPDATE: We have found data for EWE’s proposed flow battery system on the EWE Gasspeicher website. The actual values are not far off those calculated in our original article below.

A study last week showed flow batteries could maintain a cost edge over lithium-ion chemistries, even in the face of massive deployment of the latter.
