Despite these limitations, nickel-hydrogen batteries excel in durability, with a lifespan of 30,000 charge cycles—equivalent to up to 30 years of use. EnerVenue estimates they retain 86 percent capacity even after extensive use. This makes them a promising alternative for long-term energy storage in a sustainable energy future.
Advancing sustainability
RWE’s pilot project at its US testing facility near Milwaukee will evaluate EnerVenue’s ESV batteries.
The project’s objectives are to evaluate overall efficiency, temperature resilience, duration, charge and discharge performance, and cycling adaptability. RWE will use the data from these experiments to improve the technology in preparation for possible future energy project integration.
