Abstract

Towards Net-Zero emissions goal in 2050, the UK has set a greenhouse gas emissions target to reduce its environmental footprint. Consequently, the exploitation of alternative low-carbon pathways and energy carriers for the heat sector are required. In this work, we propose a multi-period, spatially-explicit mixed-integer linear programming (MILP) optimisation framework for hydrogen infrastructure to meet hydrogen heating demand in Great Britain. The mathematical model aims to minimise the total cost accounting for investment and operational decisions. The proposed optimisation framework includes dual temporal resolution: 5-year steps 2035- 2050 and typical days with hourly resolution. To enhance the computational performance of the studied model, we developed a hierarchical solution approach that results in near-optimal solutions while reducing the solution time by an order of magnitude.
