As the global pursuit of carbon-neutrality targets intensifies, the production of green hydrogen, has emerged as a key pillar for fostering a transition to climate-neutrality. Green hydrogen, produced through splitting water molecules into its constituent parts via green-powered electrolysis, is seen as a pathway for reducing the carbon footprint of today’s CO2-intensive hydrogen production. It is particularly seen as an energy vector for decarbonizing the hard-to-abate sectors, as well as a possible long-term storage medium in a future energy system dominated by variable renewable energy sources.
