Hydrogen Refuelling from the Network
Abstract
Wales & West Utilities (WWU) is undertaking a project to develop a thorough understanding of the technical and economic requirements for integrating hydrogen refuelling stations (HRS) into the existing gas network. The main aim is to enable the supply of ‘on-spec’ hydrogen for fuel cell electric vehicles (FCEVs) and hydrogen internal combustion engines (HICEs) from the heat-grade hydrogen currently delivered by the network. This involves analysing the types of contaminants present in grid hydrogen, pinpointing the purification technologies needed, and assessing the infrastructure requirements for compression, chilling, and storage to deliver hydrogen at the target pressures of 350 and 700 bar.
