ISRAEL: 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 grew out of a need to provide utilities and large-scale industrial clients a cost effective and reliable way to store energy. The company has scaled from a one watt lab proof of concept single cell system, to the recently operational multi-stack full system.
During this period, the system's components have been put through extensive testing that proved stable operations over 10,000 cycles. EnStorage's technology breakthroughs are covered by an extensive IP portfolio, which includes the core technology, materials, membrane and operations.
EnStorage flow batteries utilize HBr and H2 as storage chemicals. Abundance of these materials reduces the chemical cost by 95% compared to other batteries, making it the most affordable flow battery in the market. Moreover, the battery's proprietary conversion stacks has demonstrated over three times the power densities compared to other batteries, making it smaller and lower in cost.
