Recommendation 56

Transportation and transmission networks for hydrogen and electricity will need to be substantially improved and expanded. There is a need for sensible coordination in the design of hydrogen and electricity systems. Co-locating electrolysers and hydrogen-to-power generation with storage seems the most efficient option, but this will require significant electricity transmission infrastructure connecting storage sites to generation and to the grid. Hydrogen pipelines could connect storage to planned hydrogen industrial hubs. Without some assurance around how transmission networks will evolve, it will be hard for investors to make large-scale investment decisions into storage.
