Renewables & Green Hydrogen
Green Hydrogen
Hydrogen has been used for more than a century in industrial processes including the chemicals sector, refining, thermal treatments, cooling of generators, as a propellant fuel and in the food industry. To date, hydrogen has been produced mainly through steam methane reforming of natural gas. To reach net-zero emissions requires decarbonised hydrogen production. This can […]
