- Future Hydrogen Production Methods

A number of hydrogen production methods are in development:

  • High-Temperature Water Splitting: High temperatures generated by solar concentrators or nuclear reactors drive chemical reactions that split water to produce hydrogen.
  • Photobiological Water Splitting: Microbes, such as green algae, consume water in the presence of sunlight, producing hydrogen as a byproduct.
  • Photoelectrochemical Water Splitting: Photoelectrochemical systems produce hydrogen from water using special semiconductors and energy from sunlight.


The major hydrogen-producing states are California, Louisiana, and Texas. Today, almost all of the hydrogen produced in the United States is used for refining petroleum, treating metals, producing fertilizer, and processing foods. 

The primary challenge for hydrogen production is reducing the cost of production technologies to make the resulting hydrogen cost competitive with conventional transportation fuels. Government and industry research and development projects are reducing the cost as well as the environmental impacts of hydrogen production technologies.
