The energy sector is witnessing a fundamental shift away from fossil fuels and towards low-carbon alternatives. Countries around the world are aiming for zero emissions by 2050 and green hydrogen has been identified as a major enabler in securing a sustainable future. Its ability to convert, store and transport energy derived from other sustainable sources, such as wind and solar power, while producing zero emissions makes green hydrogen a valuable solution in the global energy transition and we are starting to see the green shoots of global hydrogen markets starting to take hold.
HOW CAN GREEN HYDROGEN CHANGE THE WAY WE USE ENERGY?
The key hydrogen technology in the production of green hydrogen is Water Electrolysis.
Using energy from renewable sources, Water Electrolysers generate ‘green hydrogen’, by splitting water into its component molecules, Hydrogen (H2) and Oxygen (O2), resulting in zero greenhouse gas emissions. By using this process of extracting hydrogen when there is excess energy in the grid – particularly on windy or sunny days, green hydrogen can be produced from renewable sources and stored cheaply for later use. Fuel cells or turbines can then convert the stored hydrogen back into electricity when it is needed.
