Whereas hydrogen is currently a marginal energy carrier, the aim of the EU is to trigger renewable hydrogen production that covers around 10 percent of EU’s energy needs by 2050. If this comes true, it will be an energy revolution. We study competition between green and blue hydrogen by drawing on economic theory to build a model that encompasses the value chains for hydrogen and CCS. We distinguish between central hydrogen production and local hydrogen production. Under central production, natural gas is transformed to hydrogen close to the extraction site and hydrogen is then transported over a long distance to terminals. Under local hydrogen production, natural gas suppliers continue to export natural gas, but now natural gas is transformed to hydrogen at terminals located far from the extraction site. For both cases of hydrogen production, there are interrelationships with the CCS industry because also blue hydrogen requires storage of captured CO2. We find that mark-ups are highest in the case with central hydrogen production, which imply that total production of hydrogen, supply of blue hydrogen and share of plants investing in capture facilities is lower under central production than under local production. In contrast, green hydrogen production is highest under central hydrogen production.
