In contrast to lithium-ion battery cells, EnerVenue’s nickel metal-hydrogen expertise has not proven fireplace 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 fireplace propagation evaluations. The corporate additionally licensed its Power Storage Vessels to UL 1973.
UL 9540A testing consists of bigger fireplace checks that start on the cell stage and progress to the module stage, unit stage, and at last the set up stage. The checks are designed to find out the danger of thermal runaway and fireplace propagation in battery vitality storage techniques.
Most lithium-ion applied sciences generate sparks throughout UL 9540A testing on the cell stage. For instance, a punctuated lithium-ion cell will burn and because of this producers add extra safety across the cells to comprise thermal runaway on the module stage and meet check standards.
EnerVenue’s Power Storage Vessels have accomplished UL 9540A testing on the cell stage with no flames noticed throughout induced thermal runaway.
“Our UL 9540A check outcomes verify our confirmed battery chemistry because the main selection for patrons involved with eliminating the opportunity of fires or thermal hazards of their grid installations- scale,” stated Majid Keshavarz, CTO of EnerVenue.
As a result of its metal-hydrogen batteries don’t require extra packaging or modification to forestall explosion or fireplace propagation, EnerVenue claims its prospects are in a position to scale back venture danger, OPEX prices , personnel danger, and environmental considerations.
In one other security milestone, the corporate additionally licensed its Power Storage Vessels to UL 1973. The protection customary applies to stationary batteries and confirms the flexibility of a battery system to function safely underneath regular and irregular 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 techniques,” stated Andrzej Skoskiewicz, vice chairman 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 subsequently 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 expertise 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 12 months.
In March, the US startup introduced its plans to spend money on a a million square-foot gigafactory within the state of Kentucky, the place it should design, manufacture and check 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.
