While renewable energy sources such as solar and wind power offer promise for future energy supplies, these renewable sources are not consistently accessible, and thus storage must be an integral part of the energy solution. Hydrogen generation from renewable energy sources for frequency regulation and load shifting during peak production times for use during low production periods is one attractive solution.

Proton exchange membrane (PEM) electrolysis is a promising technology for hydrogen generation applications because of the lack of corrosive electrolytes, small footprint, and ability to generate at high pressure, requiring only deionized water and an energy source.

The HOGEN® C-series hydrogen generation system is the latest offering from Proton OnSite for large-scale hydrogen production from renewables. The C-series system builds directly off the commercial success of other currently fielded HOGEN systems with improvements in efficiency and installed capital cost per kg of hydrogen.

Enhanced system controls include an energy conservation mode for both the generator and temperature control unit that is well-suited to the intermittent hydrogen demand from wind or solar power. With an integrated DI water system, hydrogen quality monitoring, internal temperature control, and self-contained automatic safety system, the HOGEN C-series is a turnkey, completely integrated system for renewable hydrogen generation.
