EnerVenue has developed a new metal-hydrogen battery. The American startup claims that the batterys efficiency ranges between 80% and 90%, depending on the cycle rate, and claims that its energy density per square foot is equal to or even better than that of lithium-ion batteries. .
US startup EnerVenue has developed a new version of its nickel-hydrogen batteries for large-scale renewable energy and storage applications.
“The latest version of EnerVenue batteries extends the solutions durability, operational flexibility and cost-effectiveness benefits for stationary storage projects across countless use cases,” the manufacturer said in a statement. “Next-generation ESVs can flexibly cycle up to three times a day, with discharge rates from two to 12 hours, enabling unique applications and business models for developers, integrators and owners.”
The battery reportedly has a lifespan of 30 years and 30,000 cycles, and the manufacturer offers a 20-year, 20,000 cycle warranty that guarantees at least 88% remaining battery capacity after that period.
EnerVenue claims its nickel-hydrogen battery technology can operate at temperatures between -40°C and 60°C. It can also deliver the promised cycles without degradation and at different rates, for a wide range of fast and slow charging capabilities.
According to the company, the battery has an efficiency ranging from 80% to 90%, depending on the cycle rate, and its energy density per square foot is equal to or better than that of lithium-ion batteries.
In May, EnerVenue conducted UL 9540A thermal runaway fire spread evaluations at the cell, module, and unit levels. According to Majid Keshavarz, chief technology officer at EnerVenue, the company certified its energy storage vessels to UL Standard 1973. According to Keshavarz, the UL 9540A test results validate the companys battery chemistry as the best option for customers. customers who want to eliminate thermal or fire risks in their facilities at grid scale.
Nickel-hydrogen battery technology is especially good in remote and harsh conditions, with operating temperatures ranging from -40ºC to 60ºC, as demonstrated by its use on NASA satellites.
EnerVenue raised $125 million in a Series A equity offering in December 2021 from Schlumberger, Saudi Aramco Energy Ventures and Stanford University. She was advised by Barclays. The funding round followed another $12 million seed round earlier that year.
In March, EnerVenue announced plans to invest in a gigafactory in the US state of Kentucky, where it will design, manufacture and test its hydrogen-nickel energy storage vessels. EnerVenue has received more than 7 GWh of customer commitments, including orders from Pine Gate Renewables, Nicon Industries Green Energy Renewable Solutions unit and Schlumberger New Energy. |
