Hydrogen technologies

Hydrogen technologies are technologies that relate to the production and use of hydrogen. Hydrogen technologies are applicable for many uses.

Some hydrogen technologies are carbon neutral and could have a role in preventing climate change and a possible future hydrogen economy.
