Acorn is a joint venture with four partner companies (Storegga, Shell UK, Harbour Energy and North Sea Midstream Partners) developing decarbonisation projects in Scotland.

Acorn CCS is a catalyst for industrial decarbonisation in Scotland, providing the critical infrastructure for the decarbonisation of the Scottish Cluster. Acorn has received some funding from the UK and Scottish governments, as well as the European Commission.

The Scottish Cluster is a collection of industrial, power and hydrogen businesses in the Central Belt and North East Scotland who will capture their CO₂ emissions and then move them permanently into the Acorn CCS geological stores, deep under the North Sea.
