The UK has taken a major step in its carbon capture and storage (CCS) efforts with the launch of the country’s first CO2 injection test into a depleted gas reservoir in the Southern North Sea.
Led by Perenco UK in partnership with Carbon Catalyst Ltd and Harbour Energy, the test is part of the Poseidon CCS project, which aims to store up to 40 million tonnes of CO2 per year by 2029. The test will provide critical data on using depleted reservoirs for permanent CO2 storage.
“This is a key moment, not only for Perenco and the wider Project Poseidon Joint Venture, but also for the UK’s decarbonisation ambitions,” said Jo White, General Manager at Perenco UK. “If successful, the project could be a significant store for CO2 in the future, playing a role in decarbonising industrial emitters and helping the UK achieve its Net Zero objectives.”
The test follows months of preparatory work, including a workover of a former gas production well, now configured for CO2 injection. The ERDA rig, operated by Petrodec, is the first in the UK to secure an approved safety case for CO2 injection support.
