The investment enables EnerVenue to accelerate the development of its safe, maintenance-free and cost-efficient clean energy storage solution. Based on technology proven over decades under extreme aerospace conditions – including powering the International Space Station and Hubble Space Telescope – EnerVenue now brings metal-hydrogen batteries to the mass market with compelling financial and performance advantages over lithium-ion and other incumbent renewable energy storage alternatives.
“As an example of metal hydrogen batteries, nickel-hydrogen batteries have proven to be an incredibly powerful energy storage technology – albeit an expensive one – for the aerospace industry over the past 40 years,” says Dr. Yi Cui, chairman and chief technology advisor at EnerVenue.
“The performance and longevity of nickel-hydrogen batteries is well-established and second to none. We’re now able to deliver the same performance and durability at a breakthrough competitive price using new low-cost materials,” he adds.
Renewable energy generation is expected to account for more than half the world’s power supply by 2035, rising to 75% by mid-century. The cost of lithium-ion batteries has decreased quickly and markedly, enabling more enterprises and utilities to harness renewable energy sources at scale. However, lithium-ion batteries – as well as lead-acid or redox flow alternatives – incur relatively high operating expenses, struggle in extreme hot or cold climates, have a limited lifespan, and can impose safety and environmental challenges. The EnerVenue’s metal-hydrogen batteries can last more than 30 years, with cost-per-kilowatt-hour cycles as low as a penny.
The EnerVenue metal-hydrogen batteries are developed for large-scale renewable and storage applications and designed to be:
-Durable: Operates in -40° to 140°F ambient temperatures; 30+ year lifespan; 30,000+ cycles without degradation; excellent overcharge, overdischarge, and deep-cycle capabilities
-Safe: No fire or thermal runaway risk; no toxic materials; easy to recycle
-Flexible: Broad charge/discharge range of C/5 to 5C; future-proof with no limitations on use cases; scalable form factor for grid-scale implementations
-Maintenance-free: No moving parts; 30+ year lifespan with no routine maintenance or augmentation
-Affordable: Low-cost materials; CAPEX that beats lithium-ion learning curves; no ongoing maintenance costs
-Proven: Nickel-hydrogen batteries have completed more than 200 million cell-hours in orbital spacecraft and more than 100,000 charge/discharge cycles
