The transition towards a lower carbon emissions future requires mobilizing a wide range of technologies to ensure that energy supply remains secure and affordable. Clean hydrogen offers significant potential to reduce CO2 emissions, especially when produced from decarbonized electricity or combined with carbon management technologies, such as carbon capture and utilization or storage (CCUS) technology. Furthermore, hydrogen is capable of facilitating energy transitions in sectors that are technically difficult to decarbonize, such as flexible power generation, transport, heating, and energy-intensive industry.
Clean hydrogen can be produced from different sources, including renewable electricity (green hydrogen) and natural gas reforming with carbon management technologies (blue hydrogen). If hydrogen is produced with biomass or biogas with carbon management technologies, this would result in negative emissions, removing CO2 from the atmosphere.
