wpkg flag 4 WP4 : Environmental impact & techno-economic aspects

Our Life Cycle Assessment (LCA) considers the full chain of ship-based carbon capture (SBCC) for both EverLoNG ships, including the fate of the captured CO2 once offloaded, transported and geologically stored or utilised.  Results will be benchmarked against operation without SBCC.

The LCA will investigate the impact of greenhouse gas (GHG) emissions alongside other impact categories, such as particulate matter formation or fossil depletion potential. This will help us understand whether there is a trade-off between GHG reduction and other environmentally significant categories.

Mandatory energy efficiency measures – known as the EEDI/EEXI indexes – are another approach to quantifying SBCC emission reductions. Work packages 4 and 5 will make use of findings in this area from work package 3.

Current thinking suggests that SBCC is economically viable so we will fully explore the techno-economic aspects of full-scale SBCC, including onboard capture, intermediate CO2 storage and the cost of full CCUS chains. A methodology will be developed that will help to identify an optimal strategy based on transit length and the availability of ports with CO2-receiving infrastructure. This methodology will be used for Techno-Economic Analysis (TEA) on full CCUS chains.
