Department for Energy Security and Net Zero (DESNZ) – Hydrogen Site Studies

 Project Outline

The UK Government formed DESNZ, with the responsibility to ensure that the UK has energy supplies that are reliable, affordable and clean. Its projects also aim to support the development of a thriving low carbon hydrogen sector in the UK to meet our increased ambition for 10GW of low carbon hydrogen production capacity by 2030.

Long O Donnell (LOD) were commissioned to conduct a pathfinder study, to fully assess the feasibility, costs and other impacts of converting CDS and large service sites to hydrogen. This assessment produced an initial understanding of the technical challenges which a potential hydrogen conversion would pose for CDS and large service sites and will enable categorisation of similar and dissimilar site types to assist with planning future phases of work. The types of sites were broad and included Airports, Shopping Centres, Schools, Ports, Hospitals, Rail and Bus stations.

LOD produced quality-assured summary reports detailing the common themes found during the site studies including considerations relating to hydrogen conversion. These reports helped to identify similarities and differences between sites and identify patterns based on factors such as site use, building type, age, construction materials etc.
