Renewable hydrogen can play a prominent role in decarbonising energy-intensive industries as well as heavy-duty or long-distance transport modes. It also harbours significant potential to contribute to the EU’s greenhouse gas emission reduction target by replacing today’s fossil-based hydrogen production and fossil fuel consumption in industry and the transport sector. Renewable hydrogen production from solar and wind resources will also support energy system integration. With an accelerated deployment, the share of hydrogen in the EU’s energy mix could be as much as 13-20% in 2050.
