EnStorage, Inc., a developer of large scale electricity storage solutions, has produced the first ever grid connected Hydrogen-Bromine (HBr) flow battery. The 50 KW battery was connected at the company’s test site in southern Israel and provides up to 100 KWh of energy.

EnStorage flow batteries utilize HBr and H2 as storage chemicals. Abundance of these materials reduces the chemical cost by 95 percent compared to other batteries, making it an affordable flow battery. Moreover, the battery’s proprietary conversion stacks has demonstrated more than three times the power densities compared to other batteries, making it smaller and lower in cost.
