Acorn CCS Project

A minimum viable development full chain industrial CCS project

What makes Acorn special_leaves

Project Overview

Acorn will use the unique combination of legacy circumstances in North East Scotland to engineer a minimum viable full chain carbon capture, transport and offshore storage project to initiate CCS in the UK. The project will seek to re-purpose an existing gas sweetening plant with existing offshore pipeline infrastructure connected to a well understood offshore basin, rich in storage opportunities.

CCS is an essential technology for the mitigation of CO2 emissions from large-scale fossil fuel use and is the only decarbonisation option available for many industrial sectors. CCS is therefore also essential for competitiveness, job retention and job creation at home, nationwide and across Europe.

Acorn will involve:

  • Repurpose or rebuild an existing CO2 capture plant at the coastal St Fergus gas processing plant in NE Scotland
  • New CO2 gathering, conditioning and compression
  • An existing offshore pipeline for CO2 transportation to the central North Sea selected from a portfolio of existing gas pipelines awaiting decommissioning
  • Injection into a subsurface storage site close to the pipeline corridor using proven subsea well technology.

On the 20th June 2018, the ACT Acorn project hosted a webinar called Acorn 2025: A Pathway to decarbonising the UK. For more information and to listen to the recording, please click here.

Project Scope

Acorn objectives

Phase 1 of the Acorn project will produce a mature costed plan for the full chain project worked to a feasibility level. This will provide the platform for industry, local partnerships and government to move the project forward in subsequent phases. As most of the infrastructure already exists and has already been well-evaluated, it is realistic to plan for CO2 injection to storage offshore from as early as 2021/2022.

Research and development will focus on delivering a practical and realistic design with a clear forward plan for reaching a final investment decision. It is planned the project will formulate the incorporation of an “infrastructure entity” to serve as a host for preserved assets and potentially as a National CO2 Transport and Storage operator.

Acorn will establish a strong platform from which industry, local partnerships, research organisations and government could move the project forward.

Project Team

Pale Blue Dot Energy is leading the project alongside the close support of research partner Bellona and academic partners SCCS, University of Liverpool and Radboud University.


The Acorn project is a standalone industrial CCS project which has been under consideration for several years. In May 2017, Acorn was approved for financial support for the ACT (Accelerating CCS Technologies) Call. Information on the ‘ACT Acorn’ project is available on the project website:

‘CO2 Sapling’, the transportation infrastructure element of Acorn, is listed as a PCI (Project of Common Interest). More information on CO2 Sapling can be found here.
