Europe is ramping up its efforts to develop a hydrogen economy as part of its strategy to meet climate targets and lessen dependence on traditional energy sources like fossil fuels. The focus is on green hydrogen produced from renewables and low-carbon blue hydrogen, which are key technologies for achieving climate-neutral industrial processes, heavy-duty transportation, and efficient energy storage. The European Commission, under the European Green Deal, has adopted a Hydrogen Strategy that includes ambitious targets, such as building up 40GW of electrolysis capacities by 2030. This strategy is complemented by national hydrogen plans in various member states, demonstrating a strong commitment to advancing hydrogen technologies. With significant investments flowing into hydrogen projects, there is a clear momentum towards establishing hydrogen as a critical component of Europe's sustainable energy future.
