EDINBURGH, UK — Heerema Marine Contractors’ construction vessel Sleipnir has taken delivery of a ship-based carbon capture (SBCC) prototype system developed by the EverLoNG consortium.
Carbotreat and VDL Carbon Capture developed the equipment in The Netherlands.
The aim is to test all aspects of the capture and onboard storage system on Sleipnir, which can run on LNG, for more than about 500 hours, including storing CO2 as a liquid in a specially designed container.
This will later be offloaded, and the CO2 will be transported to an industrial site for further use for permanent storage subsurface.
Aside from assessing the impact of SBCC on Sleipnir’s infrastructure and emissions, EverLoNG’s researchers will study the effects of motion on CO2 capture rates and of exhaust gas impurities on capture solvent performance. A dedicated operator will be onboard to oversee operation of the system.
The prototype and vessel designs are said to also enable remote performance monitoring and supervision from shore.
It will be EverLoNG’s second demonstration campaign, following the conclusion of the SEAPEAK ARWA trial, which demonstrated a CO2 capture rate of 85%.
The consortium aims to speed up implementation of SBCC technology by demonstrating SBCC onboard LNG- fuelled ships; optimizing the integration of SBCC into existing ship infrastructure; and to facilitate development of SBCC-based CCUS chains.
The project will also contribute to the emerging regulatory frameworks for safe and effective use of SBCC in the shipping sector.
EverLoNG, which began last October, will run through March 2025. It has funding from government departments in The Netherlands, Germany, Norway, the UK and US.
TNO leads the consortium, which includes Germany’s MAN Energy Solutions and Forschungszentrum Jülich; Conoship International, Carbotreat, VDL AEC Maritime, Heerema Marine Contractors, and Anthony Veder (all The Netherlands); TotalEnergies, SINTEF, Bureau Veritas Norway, ÅKP, Blue Maritime Cluster, DNV (Norway); Lloyd’s Register, Scottish Carbon Capture & Storage, The University of Edinburgh (in the UK); and Los Alamos National Laboratory, Nexant Energy and Chemical Advisory (in the US).
