Acrolabs’s solar & wind powered Hydrogen Energy Storage System(HESS) enables power independence from the main power grid. Surplus electricity from the renewable resources is used to power electrolyzers that produce clean hydrogen. The produced hydrogen gas is stored in pressurized tanks. When the electricity is needed, the fuel cells generate electricity with the stored hydrogen. While the batteries cover small scale power demand, this system ensures the lager scalability.
This is the ultimate way to implement zero-energy building in large scale without outside power gird.
