Solar-to-Hydrogen Tech Sees "Remarkable" Efficiency Jump
Converting sunlight into hydrogen is a seemingly ideal way to address the world''s energy challenges. The process doesn''t directly involve fossil fuels or create any greenhouse gas emissions.
Hydrogen is an energy carrier. Energy carriers transport energy in a usable form from one place to another. Elemental hydrogen is an energy carrier that must be produced from another substance. Hydrogen can be produced—or separated—from a variety of sources, including water, fossil fuels, or biomass and used as a source of energy or fuel.
Wind-to-Hydrogen Project | Hydrogen and Fuel Cells | NREL
The energy from the 10-kW wind turbine is converted from its wild AC form to direct current (DC) and then used by the electrolyzer stack to produce hydrogen from water. The energy from the 100-kW wind turbine is monitored with a power transducer, and stack current on the 33-kW alkaline stack is varied proportionally.
