Multi-model assessment of heat decarbonisation options in the UK using electricity and hydrogen

Delivering low-carbon heat will require the substitution of natural gas with alternatives such as electricity and hydrogen. The objective this paper is to develop a method soft-link two advanced, investment-optimising energy system models, RTN (Resource-Technology Network) WeSIM (Whole-electricity System Investment Model), in order assess cost-efficient decarbonisation pathways for UK while utilising respective strengths models. linking procedure included passing on hourly prices from input RTN, returning capacities locations hydrogen generation shares supply WeSIM. outputs demonstrate that soft-linking can improve quality solution, providing useful insights into zero-carbon heating. Quantitative results point cost-effectiveness using mix technologies delivering heat, also demonstrating high level interaction between infrastructure system. Hydrogen reforming carbon capture storage play significant role medium term, remaining option supplying peak demand longer bulk being supplied by electric pumps.
