Zn2H2 Grid Scale Energy Storage
Utility-scale storage can be a cost-effective way to manage grid power volatility, peak power demand, and temporary power outages.
Other hydrogen energy storage concepts use electricity to power electrolyzers to produce hydrogen that is then compressed and stored in large tanks or caverns, and then used to feed fuel cells or gas turbines to deliver power to the grid.
Zn2H2’s system takes in energy like a battery (recharging the metallic zinc in the generator module), then releases electricity & hydrogen on demand to feed fuel cells or gas turbines to deliver power to the grid.
Total round trip efficiency can be >50% at investment savings which overcompensate for the reduced efficiency compared to battery storage .
Zn2H2 system cost mainly scales with peak power requirements (Fuel Cell cost/Gas Turbine) and in stark contrast to lithium based systems is insensitive to storage capacity, offering solutions to unmet needs for green energy
