The main goal of the deliverable D4.2.1 is to conduct an exhaustive review and analysis of state-of-the-art green hydrogen technologies across the entire hydrogen value chain, identify promising solutions and trends using text mining and bibliographic analysis, and evaluate their potential applications for reducing carbon emissions in port systems, with a focus on the economic, social, and environmental benefits.
- The report explains the utility of hydrogen for the transition into a CO2-free energy sector. It explores how hydrogen stores energy and carries it in space and time, making it particularly suitable to couple with intermittent renewable energy sources.
- The report surveys the main technologies for producing green hydrogen. This is followed by a bibliometric analysis that examines the number of patents and scientific articles related to different hydrogen production technologies over time. This bibliometric analysis also encompasses other forms of hydrogen production.
- Another section explores hydrogen storage, and examines chemical storage alternatives, including methanol, ammonia, and organic carriers.
- A dedicated section covers hydrogen distribution methods, providing examples of practical implementation.
- The report gives an overview of hydrogen applications and end uses, particularly in transportation, where it can play a significant role in decarbonizing the sector.
- In the second main part of this report, a major component is dedicated to exploring potential sources and applications of green hydrogen in ports, particularly in Europe and the Atlantic region. Sources and applications are analysed by compiling and cross-referencing data from a comprehensive literature review, direct communications with initiative partners, and various reliable sources such as digital press, association websites, and project repositories.
