In contrast to lithium-ion battery cells, EnerVenue’s nickel metal-hydrogen know-how has not proven hearth propagation throughout thermal runaway induction in UL battery security testing.
US vitality storage firm EnerVenue has accomplished UL 9540A cell-, module- and unit-level thermal runaway hearth propagation evaluations. The corporate additionally licensed its Power Storage Vessels to UL 1973.
UL 9540A testing consists of bigger hearth assessments that start on the cell degree and progress to the module degree, unit degree, and at last the set up degree. The assessments are designed to find out the chance of thermal runaway and hearth propagation in battery vitality storage programs.
Most lithium-ion applied sciences generate sparks throughout UL 9540A testing on the cell degree. For instance, a punctuated lithium-ion cell will burn and for that reason producers add further safety across the cells to include thermal runaway on the module degree and meet check standards.
EnerVenue’s Power Storage Vessels have accomplished UL 9540A testing on the cell degree with no flames noticed throughout induced thermal runaway.
“Our UL 9540A check outcomes validate our confirmed battery chemistry because the main alternative for purchasers involved about eliminating the potential for fires or thermal hazards of their installations. grid-scale,” mentioned Majid Keshavarz, CTO of EnerVenue.
As a result of its metal-hydrogen batteries don’t require further packaging or modification to stop explosion or hearth propagation, EnerVenue claims its clients are in a position to scale back challenge threat, OPEX prices , personnel threat, and environmental issues.
In one other security milestone, the corporate additionally licensed its Power Storage Vessels to UL 1973. The security commonplace applies to stationary batteries and certifies the flexibility of a battery system to function safely beneath regular and irregular situations. situations associated to electrical, mechanical, and environmental security.
“UL 1973 validates and validates our security claims and satisfies a requirement for the deployment of grid-scale and industrial vitality storage programs,” mentioned Andrzej Skoskiewicz, vp of engineering of the EnerVenue product.
Based in 2020, EnerVenue claims that its nickel-hydrogen batteries have lifespans of greater than 30 years to greater than 30,000 cycles with out experiencing degradation and due to this fact with out upkeep prices. The corporate additionally claims prices per kilowatt-hour are as little as one cent, in addition to the capital expenditure price of beating lithium-ion batteries.
As demonstrated by its use in NASA satellites, nickel-hydrogen battery know-how excels in distant and harsh situations with working temperatures between -40 C to 60 C. The EnerVenue battery has an effectivity from 80 to 90%, relying on the cycle fee, and its vitality density per sq. foot is the same as, or higher than lithium-ion batteries, based on the corporate.
EnerVenue raised $125 million in a December 2021 Collection A fairness providing from Schlumberger, Saudi Aramco Power Ventures, and Stanford College, and was suggested by Barclays. The funding spherical follows an earlier $12 million seed spherical that yr.
In March, the US startup introduced its plans to put money into a a million square-foot gigafactory within the state of Kentucky, the place it is going to design, manufacture and check its nickel-hydrogen Power Storage Vessels.
EnerVenue stories that it has greater than 7 GWh of buyer commitments, together with from Pine Gate Renewables, Nicon Industries’ Inexperienced Power Renewable Options, and Schlumberger New Power, amongst others.
