We are happy to present the third publication of the EHA/DWV series of strategy papers on the role of hydrogen as an energy carrier in a changing energy and climate landscape. The first paper dealt with the status of supply of different primary energy sources for hydrogen production, clearly indicating that renewable energy sources will be the most secure and sustainable source for future hydrogen production. The second paper demonstrated the role of hydrogen and fuel cells to facilitate large scale renewable energy deployment. This third paper explains the role of hydrogen in developing an intelligent and efficient infrastructure for electric mobility as we will need to gradually replace depleting fossil fuels with more renewable sources.
