About Hydrogen

Hydrogen provides a new way to store and transport energy, and it can do this with no carbon emissions.

Hydrogen can be used to store renewable energy from solar photovoltaics (PV) and wind, which can then be used to:
- Export to nations that are moving toward a hydrogen economy.
- Help manage the security of the electricity grid by:
  - storing excess renewable energy from one time period (and place) and then releasing the energy back into the grid when (and where) it’s needed; and
  - using electrolysers (which produce hydrogen from water) as a flexible load that can come on and off quickly to support the grid.
Hydrogen can be used to take the carbon out of:
- Transport, including heavy road vehicles, trains, ferries, ships and planes.
- Carbon emissions-heavy processes, such as for the production of chemicals and steel.
Hydrogen connects the transport and energy sectors in a new way, allowing for energy to be converted across uses. It can be produced on-site, with an electrolyser using only electricity and water as inputs.
