UK Readies Carbon Storage Road-map

February 9, 2020

Heriot-Watt University researchers are to map out the UK’s best sites for carbon capture by studying the geology of depleted gas fields in the North Sea.

The team led by Professor John Underhill will use data from industry regulator the Oil and Gas Authority's (OGA) National Data Repository (NDR), which was opened up to access for the first time in 2019.

Professor John Underhill said: “The Southern North Sea faces three of some of the UK’s largest carbon emission areas: the industrial hubs of Teesside, Humberside and the Thames estuary.

“It also has a number of depleted gas fields that could be re-purposed to store carbon.

“We are going to systematically examine the geology of these sites and determine which critical factors allow carbon to be safely stored over long, geological timescales.”

The team will create a roadmap for other sites by mapping the geological features and their carbon storage potential.

The best sites and any potential leakage points will be identified. Accurate mapping of the overburden will be used to develop mitigation strategies and early warning systems for any carbon escape or seepage.

The team will use data from the OGA’s National Data Repository (NDR), one of the largest-ever single open releases of field and infrastructure data from the UK’s oil and gas industry, which was made open access for the first time in 2019.

The project will receive funding from the OGTC’s Subsurface Solution Center, which is supporting accelerating decarbonisation technologies in the UK.

Gillian White, Subsurface Solution Center Manager at the OGTC said: “This is an exciting example of transferring skills from the oil and gas industry to carbon capture and storage, alongside sharing knowledge and data.

“Ultimately this project will give policymakers the tools they need to determine the most suitable sites for carbon capture and storage, which is aligned with OGTC’s vision to transform the UKCS into a net zero basin.”

The OGTC award aligns with its 2025 goal of advancing research in the clean energy transition and has attracted matched funding from industry and Heriot-Watt University.

Professor John Underhill said: “If we are to reach net zero targets we must make serious progress in carbon capture and storage.

“We need to identify the best sites based on their geology and evaluate the risk of leakage, so that we select the right sites, in the most logical order, and understand the total volume of carbon that could be stored.

“We must do this correctly and on a large scale. We won’t get a second chance to get this right, as all credibility will be lost if leakage takes place from a poorly-selected site.”

The Heriot-Watt team is currently recruiting two research associates to join the team and conduct the research.
