Mapping geological hydrogen storage capacity and regional heating demands: An applied UK case study

Hydrogen is considered as a low-carbon substitute for natural gas in the otherwise difficult to decarbonise domestic heating sector. This study presents first time, globally applicable source sink methodology and analysis that matches geological storage capacity with energy demand. As case study, it applied system UK, focus on maintaining existing distribution network. To balance significant annual cyclicity demand heating, hydrogen could be stored fields offshore transported via pipelines terminals into The UK estimated ~77.9 terawatt-hour (TWh), which approximately 25% of total from used heating. included this 2661.9 TWh. reveals only few are required store enough entire seasonal It also demonstrates so required, will not compete subsurface space other applications, such carbon or compressed air storage.
