Hydrogen is a promising alternative fuel in its infancy.
Hydrogen is stored in water, hydrocarbons, and organic matter. Steam reforming is the most common method of producing hydrogen, it involves the combination of high-temperature steam with natural gas. Hydrogen can be produced from water through electrolysis. Using renewable energy can help reduce emission generation during the production of hydrogen.
Light-duty fuel cell electric vehicles (FCEV) are available in limited quantities. FCEVs emit water vapor and warm air as exhaust. The market for buses, forklifts, medium-duty, heavy-duty, marine vessels and stationary applications is in development.
Both the public and private sectors are actively working towards widespread production and distribution.
