Tetra Tech delivered a Pre-Front-End-Engineering-Design (Pre-FEED) Study for infrastructure to collect, transport, store and export 3 Mt CO₂/year, supporting Ireland’s Climate Action Plan.
Ervia is the company responsible for the delivery of Ireland’s national gas and water infrastructure and services. We delivered a Pre-Front End Engineering Design Study (Pre-FEED Study) to Ervia to support the business case development for this Carbon Capture & Storage (CCS) project in Ireland.
Challenge
The study defined the key parameters, technical elements, and configuration of the infrastructure that will be required to collect, transport, store and export a total of 3 million tonnes per annum (Mtpa) of CO₂ from emitter clusters in Cork and Dublin. At approximately 5% of Ireland’s national CO₂ emissions, the project could become a significant contributor to meeting targets for CO₂ reduction set out in Ireland’s Climate Action Plan. Initially, CO₂ would be exported (from Cork and Dublin) to the Equinor Northern Lights Project (the North Sea, off Norway) by ship.
Solution
We examined the feasibility of importing CO₂ to the Cork site for onward storage to the decommissioned Kinsale Head Gas Field. This included considering using sections of decommissioned gas transmission pipelines for CO₂ transport.
This pre-FEED study called in expertise from across Tetra Tech in the UK and Ireland in safety, energy, marine, environmental, planning, pipeline, electrical, civil and structural design. The project has been delivered to a very challenging timeline and provided an updated and robust cost estimate to allow the business case to be developed further. Our multi-disciplinary project team brought together a wide range of relevant expertise, and we were able to fully address every aspect of this complex project within the tight project timescale.
In preparing this study, we worked in partnership with Bechtel to provide additional engineering, procurement and construction expertise. Other partners on this project included HR Wallingford and ARC.
It is a significant win in the carbon capture and storage market, which is a key sustainability workstream in meeting Net Zero Carbon. There is great potential for the lessons learned on this project to be applied to other future CCS projects in Ireland, the UK or further afield, in particular within the cement and thermal waste treatment sectors.
