Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, what assessment his Department has made of the potential merits of modelling sector coupling between electricity and hydrogen for the UKs energy system.

The Department’s UK TIMES model captures interactions across the entire energy system, from fuel extraction to final energy demands, enabling comprehensive analysis of decarbonisation pathways and helping us explore the optimal future energy system. This model has been instrumental in developing departmental net zero strategy, including our understanding of the future power sector. Building on this, DESNZ recently invested in BID3, a new model designed to simulate a fully connected power and hydrogen market across the UK and EU. BID3 will model power generation, hydrogen production, transmission, gas transport, interconnectors, and storage, allowing comparison of whole-life system costs and cashflow, across future scenarios.
