SCO - Low-Carbon Hydrogen: Blue Or Green

• Hydrogen is expected to play a key role in the decarbonisation of the energy system, particularly in hard-to-abate sectors such as industry, road freight, shipping and aviation.
• The demand for hydrogen is likely to be met through the production of both blue and green hydrogen, which together are referred to as low-carbon hydrogen.
• Blue hydrogen is derived from natural gas; Green hydrogen is produced by splitting water using electrolysis that has been powered by renewable energy sources.
• Close to 60 blue hydrogen projects are planned or in development worldwide and, if realised, would produce almost 9Mt of hydrogen by 2030.
• Project sizes for green hydrogen have been increasing from the 1MW to 5MW range pre-2020 to projects in the hundreds of megawatts range announced in 2020 that are expected to become operational in the coming years.
