Opened the debate
Kieran Mullan, MP for Bexhill and Battle, highlighted the potential of deep geothermal energy as a sustainable and cost-effective source of heat and power in the UK. He discussed how this technology could help achieve net zero emissions by reducing reliance on gas boilers and supporting the transition from fossil fuels to renewable energy sources. Mullan mentioned successful projects in Germany and France that have utilized deep geothermal energy, emphasising the need for government support similar to what other countries provide. He outlined a potential tariff support proposal of £55 per megawatt-hour for 30 initial plants over 20 years, suggesting this level of investment could be justified given its value for money compared to green gas industry support. Mullan also pointed out the opportunity for deep geothermal energy to help areas in need of levelling up and to recruit from the existing oil and gas workforce.

Government Response
Jacob Young, Minister of State for Energy Security and Net Zero, thanked Kieran Mullan for his report on deep geothermal energy and its economic opportunities. He reiterated the government’s commitment to net zero by 2050 and highlighted recent progress in renewable electricity generation in the UK. The minister acknowledged the potential of geothermal power demonstrated by projects such as United Downs near Redruth, Cornwall, which will begin generating next year with a baseload capacity of 2 MW rising to 25 MW after four years. Young noted the technology’s potential for creating skilled jobs and enabling decarbonisation in various sectors including heat network schemes and battery-grade lithium extraction. However, he also mentioned challenges like higher drilling costs compared to other renewables and uncertainties regarding geological risks. The minister committed to continuing support through mechanisms such as the green heat network fund and contracts for difference scheme. He emphasised the government’s determination to explore every home-grown green technology available in transitioning to a net zero economy.
