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.
“This is a major milestone and a step forward towards larger capacity products,” says Dr. Arnon Blum, president of EnStorage, Inc. “With the 50 KW system we have refined our ability to manage multiple battery stacks, which is key to providing a modular and cost effective storage system for our customers.”
EnStorage, Inc. 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 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.
“We believe that by making energy storage simple and affordable we can tackle the major issues facing the energy sector,” said Dr. Blum “EnStorage batteries can firm up renewable energy by eliminating intermittency, align energy availability with demand for load leveling and peak shaving, defer transmission and distribution upgrades, and provide instant congestion relief, solving immediate grid constraints.”
Following the recent success of the 50 KW unit, EnStorage is now moving forward with the next milestone of a 150 KW, six hours of storage, commercial unit.
