As work proceeds on different areas of the ACT Acorn project, we bring you the latest reports, which are now available in the new Downloads section of our website.
With the first two project milestones now complete, you’ll find reports on, for example, CO2 supply options for building out from the initial full-chain project and more about the Feeder 10 gas pipeline, which will be a key piece in the Acorn jigsaw. Other important research includes work to identify the most suitable CO2 storage site for the project.
Check out our report summaries below then head to Downloads, where we will be uploading subsequent reports as research on the different work packages continues.
ACT Acorn Kick Off Meeting
The kick-off meeting for the ACT Acorn project took place on 26-27 September 2017 in two half-day sessions in Aberdeen and Peterhead. This report sets out the project’s direction and delivery framework, and shares some of the meeting materials, including photographs from the meeting.
ACT Acorn CO2 Supply Options
This report establishes a reference profile of CO2 supply that will be used for the design of the St Fergus capture facilities, the storage development plans, economic analysis for the project and the build-out vision. The report proposes two scenarios, which include an inventory of 13 existing sources, plus future emissions, including CO2 from hydrogen production and CO2 import from Europe to Peterhead by ship. Feeder 10 is recognised as a key piece of infrastructure to link the industrial emissions of Scotland with the Acorn project.
ACT Acorn Feeder 10
This report summarises the current status of Feeder 10 (an existing natural gas pipeline from St Fergus to Central Scotland), draws out relevant material from previous studies on reuse and outlines the potential opportunity and business case for repurposing the pipeline for CO2 transport. The report also considers the future steps to enable the transition from natural gas to CO2. A reference scenario has been developed for the infrastructure investment, assuming a regulated asset level of return and asset transfer payment mechanism.
ACT Acorn Basis of Design for St Fergus Facilities
This report documents the design basis and conceptual design options for the capture and compression facilities required to capture CO2 from major point sources at the St Fergus gas terminals and prepare that CO2 for offshore transport and injection. Two options are identified, namely, to reuse the SAGE gas sweetening plant to capture CO2 from flue gas emissions or to build a new capture plant at St Fergus, which would have the advantage of being designed for purpose.
ACT Acorn Site Screening Methodology
The ACT Acorn project involves the selection of two sites as candidates to host CO2 storage. The first site is Captain X, appraised and characterised in the Strategic UK CO2 Storage Appraisal Project. This report outlines the methodology used to identify the second site, developing a shortlist of six high-grade potential CO2 storage sites from an initial longlist of 113 potential sites. It also forms the input for the ACT Acorn Site Selection Report.
ACT Acorn Site Selection Report & Posters
This report documents the selection process for the second site, including a description of the selection process, output from the stakeholder engagement workshop and a preliminary definition of the storage complex. The posters summarise the six shortlisted potential storage sites. The report identifies East Mey as the second site for the ACT Acorn CCS project.
ACT Acorn Plan and Budget for FEED
This report outlines the activities, resources and effort required in the next phase of the Acorn development i.e. Front End Engineering and Design (FEED). The FEED programme outlined here is informed by previous FEED studies for the Scottish Power Longannet Demo1, Shell Peterhead and Capture Power White Rose projects. Completion of the FEED programme, estimated to require 66,000 human hours of activity and cost around £15.3million, will add considerable definition to the project and take deliverables to 80-90% maturity.
ACT Acorn Expansion Options
This report develops and articulates the vision and opportunities for the build-out of the Acorn project, including CO2 ship import, hydrogen, bioenergy and CO2 utilisation. The initial capture volumes from St Fergus are only intended to initiate the Acorn project. The real opportunity lies in the build-out enabled by the capacity of the already installed infrastructure and the new decarbonisation opportunities which enable expansion.
The ACT Acorn Consortium invites you to join our first webinar, Acorn 2025: a pathway to decarbonising the UK.
The Acorn CCS project is a full-chain industrial carbon capture and storage (CCS) project being developed in north east Scotland. The linked ACT Acorn project is an international research collaboration co-funded by BEIS and the European Commission, and outputs are an important contribution to the development of Acorn.
Our webinar will introduce the Acorn project as a “look back” from the year 2025. From this future perspective, our speakers will showcase the results from the ACT Acorn study, focusing on the growth of an integrated CCS network from an initial capture plant at St Fergus, which now handles CO2 from a variety of sources – including CO2 from the local production of hydrogen and imported from other countries.
You will hear from several members of the consortium, who will address different areas of the study, from the technical details of construction and initial CO2 injection into the storage site to public perception as well as the policy and regulatory issues the project faced.
The speakers will address the importance of this early research in reaching significant project milestones in the UK and will point to Acorn’s vital role as one of several major success stories from the UK and Scottish Government’s respective clean growth and energy strategies.
