The Role and Value of CCS in Integrated Heat and Power Systems of the UK
Different carbon capture and storage (CCS) technologies likely play a significant role in the decarbonisation of energy systems. Identifying cost-optimal energy system transitions that guarantee security of energy supply throughout the process is an important challenge, as reliable access to cheap energy is essential for modern societies. However, future energy systems are subject to significant uncertainties, which include fuel prices and technology costs. Therefore, in this work an optimisation of the transition to net-zero of the UK energy system is performed, using a Monte Carlo-style approach to address uncertainty in key input parameters. The work focusses on the role and value of CCS technologies, which include gas turbines with post-combustion CCS and bioenergy with CCS for power generation, steam-methane reforming with CCS and biomass gasification with CCS for hydrogen production, and direct air capture. The analysis is performed using an integrated energy system optimisation model that explicitly considers the power and hydrogen sectors, biomass supply, and domestic, commercial, and industrial heating sectors. Results show that bioenergy with CCS plants are deployed in every scenario but play an especially important role in low-gas price scenarios. In high-gas price scenarios on the other hand, emission abatement by heat electrification via heat pumps is more prominent. Direct air capture only gets deployed in few scenarios with low gas prices and high biomass costs, providing as much as 47 MtCO2/a in negative emissions in 2050
