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.

UK£20m earmarked for Imperial College research areas

27 September 2012

The UK government is stumping up £20m for two soon-to-be-announced energy storage competitions after a study by Imperial College, London, concluded the areas they will cover could deliver a payback of £10bn a year, according to a report on the Environmental Data Interactive Exchange.

Potential applicants can already register interest in the competitions, one of which will focus on energy storage technology demonstrations, while the other will centre on component research and feasibility studies.
