Feasibility of ammonia-to-hydrogen network in the Humber Cluster
People Involved
Project Description
Fuel switching from natural gas, diesel, etc to hydrogen represents the most feasible solution to decarbonise the Humber cluster which is dominated by heavy industries with a total emission of 12.4MtCO2/year. However, pipeline transport of hydrogen to end-user heavy industries is challenging and expensive due to the compression requirement and their potential to embrittle steel pipes and therefore requiring expensive carbon fibre reinforced pipeline materials. The low volumetric energy density of hydrogen also means that substantially high flowrates will be required to meet end-user energy needs. This makes the case for hydrogen ‘carriers.
Ammonia is the most promising hydrogen ‘carrier’ due to: (a) its high hydrogen storage capacity (17.65wt.%H2); (b) its storage and pipeline transport at moderate conditions (10bar and 25°C) in liquid phase; (c) over 5 decades of industrial experience in its transport and storage; (d) the relative ease of ‘cracking’ ammonia to obtain hydrogen. We propose a decentralised model for hydrogen transport and storage with ammonia as the ‘carrier’ from potential production/import sites to end-user sites where ammonia can be? will be ‘cracked’ to obtain hydrogen. This will ensure the cost-effective delivery of hydrogen to end-users across the Humber cluster enabling the full potential of the hydrogen economy to be realised. Our project will design and perform techno-economic, safety and life cycle assessment of the proposed network, considering new and existing pipelines. This will accelerate the development of the planned hydrogen production sites at Killingholme and import terminal at Immingham, both in the Humber, creating jobs and enabling the rapid decarbonisation of the cluster.
