Professor Stuart Haszeldine is the UKCCSRC Deputy Director for Storage. He is a geologist and environmental scientist at the University of Edinburgh, with 45 years’ experience working with subsurface information from hydrocarbon extraction to waste disposal. From 2005 he has created the UK’s largest University group examining CO2 storage geology, with a particular focus on natural analogues, containment processes and subsurface pressures. His research focuses on energy and environment, linking between academia, business, government, and public engagement. He served as advisor to the 2005-6 UK Parliament Science and Technology Committee on CO2 capture and storage, and was the only academic on the seminal Oxburgh Report to BEIS of 2016. He currently serves as one of two academics on the CCUS Council, advising Secretary of State and Energy Ministers. His current work is developing the Carbon Take Back Obligation and carbon offsets, to align carbon storage tonnage with climate requirements, and also developing multi-seasonal hydrogen storage onshore and offshore UK. Stuart was awarded the Scottish Science Prize in 1999, elected Fellow of the Royal Society of Edinburgh in 2003, appointed OBE for services to climate change technologies in 2012, and in 2021 he was appointed Fellow of the Royal Geographical Society.
