Renewable hydrogen is poised to play a pivotal role in lowering carbon emissions in Europe. A recent study by the Joint Research Centre (JRC) compared the environmental impacts of different methods of delivering hydrogen over long distances. The study highlighted that on-site production with efficient renewable sources like wind power is the most sustainable approach for large industries. Importing renewable hydrogen can also reduce greenhouse gas emissions significantly. However, the study emphasized the importance of considering unintended environmental impacts beyond just greenhouse gas emissions. It also noted that transportation methods like shipping liquid hydrogen and using pipelines have lower environmental impacts for long-distance delivery. The study also underscored the role of renewable energy infrastructure in determining the environmental impact of delivered hydrogen. Additionally, the report pointed out the significance of water use in hydrogen production and the impact of hydrogen loss during the delivery chain. Overall, the findings provide key recommendations for policymakers and stakeholders to facilitate the transition to a more sustainable hydrogen economy in Europe.
