Finland's maritime technology giant Wartsila believes carbon capture and storage (CCS) can deliver quicker decarbonisation results for shipping than alternative fuels.

But some vessels are more suitable for retrofits than others.

Wartsila is currently trialling a system that it hopes can extract 70% of CO2 from exhaust gas on Norwegian owner Solvang's 21,000-cbm ethylene carrier Clipper Eos (built 2019) from 2023 or early 2024.
