The European Union is targeting to have 2% of its shipping powered by green hydrogen by 2030. Transport & Environment (T&E), an NGO advocating for clean transport and energy, has identified multiple green hydrogen projects across Europe that, if operational, could meet a substantial portion of the EU shipping energy demand. However, the production of green hydrogen-based fuels requires significant capital investments. T&E highlights a dilemma in the shipping industry where e-fuels producers are hesitant to invest without clear demand signals from shipping operators, while operators wait for these fuels to become more cost-effective. To address this, T&E suggests that EU member states should mandate a percentage of shipping fuels to be e-fuels by 2030 to offer investment certainty. Denmark is noted as a significant contributor to planned hydrogen projects, while Spain stands out for its potential fuel supplies. The UK has limited projects in this area, while Italy and Greece currently lack any identified initiatives.
