Objectives The project will follow a 5-phase approach as follows: Phase 1 - Phase 1 of the project will gather geological data on storage potential in salt formations located in the UKCS. GIS layers will be developed to illustrate salt thickness, depth, temperature, pressure and heterogeneity to establish confidence in regions for development of hydrogen storage solutions. Phase 2 - Phase 2 of the project will gather geological data on storage potential in porous rock formation located in the UKCS. GIS layers will be developed to illustrate rock thickness, depth, temperature, pressure, heterogeneity and net to gross ratio to establish confidence in regions for development of hydrogen storage solutions. Phase 3 - Phase 3 of the project will assess surface infrastructure to identify developments that may support production of green hydrogen through renewable technologies and use of electrical energy for electrolysis. Phase 4 - Phase 4 will develop a RAG assessment to evaluate data confidence and quality from previous project phases. Phase 5 - Phase 5 of the project will deliver all project findings and develop a GIS hydrogen storage database tool. The phase will also inform stakeholders of the resource to allow potential locations to feature in transition plans to 100% hydrogen.  The project proposal is outlined below: Work Package 1-Hydrogen Storage Potential in SaltsGather geological data (e.g. borehole records, seismic surveys, scientific literature)Develop geological GIS layers of salt thickness, depth, temperature, pressure, heterogeneityIncorporate geomechanically layers of major fault lines and stress fields Calculate layers of estimated hydrogen storage potential (in terms of energy density and energy capacity). Work Package 2-Hydrogen Storage Potential in Porous RocksGather geological data (e.g. borehole records, seismic surveys, scientific literature)Develop geological GIS layers of porous rock thickness, depth, temperature, pressure, heterogeneity, net-to-gross ratioGeomechanical layers of major fault lines and overpressureChemical layers for formation salinity and geochemical reactivity potentialCalculate layers of estimated hydrogen storage potential (in terms of energy density and energy capacity). Work Package 3-Surface Infrastructure AssessmentObtain rights to use renewable sources data and gas network infrastructure GIS compatible files. Obtain rights to GUS compatible files of main land use areas (e.g. urban vs rural, roads, etc.)Build a layer identifying land ownership/exploitation rights Work Package 4-Risk Identification, Data Confidence and Quality AssessmentDevelop a GIS layer for caprock sealing potential and well abandonment and its impact on seal quality. Using expert elicitation, add a traffic light ranking to evaluate data confidence and qualityWork Package 5-Project DeliveryDevelopment of the GIS hydrogen storage database A final report presenting all project findings A campaign to inform stakeholder of the resource Peer-reviewed publications to illustrate the science behind the dataset developedA summary for policy makers document to highlight the key recommendations and findings Project objectives include the development of a GIS hydrogen storage database tool that can play a key role in highlighting potential areas for hydrogen storage, feeding into decarbonisation plans of the network to 100% hydrogen. Project outputs will be invaluable to SGN and other gas network operators to understand the location and capacity of storage sites in relation to transition plans to 100% hydrogen. The project will offer a database of storage options that will ensure confidence in the scale up of hydrogen systems whilst ensuring we keep our current 1:20 and 1:50 energy security obligations. This feeds into the wider national hydrogen conversion programme and illustrates to policy makers, the viability and resilience of a 100% hydrogen energy system with available storage sites. 
Abstract The UK government has committed to reducing greenhouse gas emissions to Net Zero by 2050. All future energy modelling identifies a role for hydrogen in providing decarbonised energy for heat, transport, industry and power generation. A key element of transition to hydrogen is to ensure security of supply for customers through hydrogen storage. Our future decarbonised networks will require large scale, long term seasonal storage of hydrogen to ensure a resilient and efficient network. Storage provides the ability to maximise the use of installed renewable capacity for production and subsequent storage of green hydrogen, providing maximum economic recovery of energy. This project will provide a GIS database illustrating optimal sites for development of geological hydrogen storage.
