Acorn project signs MoU with Uniper to ship and store captured CO2
Uniper is developing proposals to retrofit post-combustion carbon capture technology on up to three units at their Grain power station, a 1,326MW Combined Cycle Gas Turbine (CCGT) plant, located in the South East of England, on the Isle of Grain.
The project could potentially capture over two million tonnes of CO2 per year.
Acorn and Uniper have entered into the MoU to jointly develop a potential solution to ship captured CO2 from the Isle of Grain to Peterhead Port in the North East of Scotland and onto the Acorn transportation and storage (T&S) network, which can then pipe the CO2 to permanent storage 2.5Km below the seabed in the North Sea using re-purposed gas pipelines.
As part of their plans, Uniper are seeking to use existing jetty infrastructure near Grain to load the ships with captured CO2 and ship it from Kent to Scotland.
The joint project would contribute to the UK government’s CCUS (Carbon Capture, Utilisation and Storage) Cluster Sequencing Track-2 ambitions.
To do this, Uniper and Acorn plan to collaborate to develop technical, commercial, and regulatory proposals to enable shipment of CO2 within this timeframe.
Mike Lockett, Uniper UK country chairman and group chief commercial officer power, said: “Uniper is investing significantly to decarbonise our existing power stations, to meet our ambitious target to generate more than 80% of our installed power capacity from carbon-free sources by 2030.
"We are exploring a range of options to transform our gas-fired generation to achieve this, from alternative fuels, such as hydrogen or biofuels, to post combustion carbon capture.
"Retrofitting carbon capture technology at Grain - one of the most efficient gas plants in our fleet, will remove millions of tonnes of CO2 during the electricity generation process, whilst still providing flexible and reliable power to the UK’s energy system.
"The MoU Uniper has signed with the Acorn project partners, is a significant step in helping to identify a solution to ship captured CO2 for permanent offshore storage.
"This is also an important step for the many other emitters across the UK who want and need to decarbonise their essential industrial processes, but require a flexible CO2 transport and storage solution to achieve this.”
