HDF Energy is a global pioneer in hydrogen power. HDF Energy develops and operates high capacity large-scale Hydrogen-to-Power infrastructure to provide firm or on-demand electricity from renewable energy sources (wind or solar), combined with high power MultiMegawatt fuel cells. HDF Energy has developed two models of turnkey Hydrogen-to-Power plants: ' Renewstable' (POWER TO POWER) Renewstable' multi-megawatt turnkey power plants producing firm renewable electricity. These power plants are composed of an intermittent renewable source and a long-term on site hydrogen energy storage. ' Hypower' (GAS TO POWER) Gas to Power' power plants producing electricity on demand from green hydrogen.
