This project assessed the potential impact of selected, identified innovations on specific types of network (relating to heat, gas, electricity and hydrogen). Generic modelled networks will be developed utilising the 2050 Energy Infrastructure Cost Calculator model developed by a separate ETI project to understand the expected costs of certain types of network.The modelled networks will provide ‘business as usual data’ and a useful basis for further understanding of the impact of identified innovations in terms of overall cost and network performance.
This report considers hydrogen..The work undertaken here made use of the first version of the ICC and as such also acted as a testing phase. Some issues arose in relation to the output of the tool particularly in respect of the treatment of operational and lifecycle costs.These findings are being fed into aparallel project to develop a second version.
Key Findings:Representative hydrogen transmission model: transmission pipeline of different lengths required to transport hydrogen from production facilities to power generation sites and vehicle refuelling sitesPipe lengths (NTS 32”) modelled for connection to production sites were 5km and 10km without the need for a compression station; pipe lengths (LTS 16”) for connection to refuelling sites were modelled at longer distances up to 200km, with a compression station required for anything over 100kmNPV/km for connecting to power stations was £5.4m for installation in 2025NPV/km for connections to refuelling sites was in the range £3.0m to £3.5m depending on network length with the higher cost relating to the need to add in a compression stationThe additionalcost of the power station scenario was due to the need to use larger diameter and hence more expensive pipeRepresentative hydrogen distribution model: distribution pipelines (LP/MP) required to connect production facilities to vehicle refuelling stations at different capacities and contextsContext is a strong influencer of costs, with first costs per km increasing from rural through to urban and London. This is due to the higher costs of installing pipework in more congested areas.Pipe costs dominate the overall network cost, particularly for the longer network lengths.There is a small increase in cost per km for the higher capacity scenariosHydrogen transmission and the impact of including storage:Connecting a single large storage site into the network is considerably less expensive than co...
