Norwegian shipowner Solvang has revealed tests have shown it is capable of capturing 60% of CO2 of a ship’s engine.
The company has been working with Finnish tech giant Wartsila since October to develop a system for ethylene carriers.
Full-scale 1.2 MW onshore testing is underway at Wartsila’s facilities in Moss, Norway.
The shipowner believes that the technique could be a game-changer for decarbonization.
“The system is already performing up to 60% carbon capture on certain engine loads, which has never been done before. Additionally, early indications are that CO2 captured is very pure, with little or no contamination of the product,” said General Manager Edvin Endresen of Solvang.
A larger kit will “soon” be installed on the 21,000 m3 ethylene carrier Clipper Eos (built in 2020), where it will serve the 7 MW main engine, Solvang added.

And by mid-2022, an electrostatic filter will be installed in the ship’s exhaust gas cleaning system, a first in the history of ship engines.
Fleet Director Tor Oyvind Ask said, “We believe deep-sea shipping can play an important role” in decarbonization.
“There are no easy solutions, so we are looking for the big game changer: avoiding CO2 emissions by capture and storage,” he added,
Solvang describes the process as a complex separation of carbon that occurs inside the chimney resulting in liquid CO2 transferred to deck tanks, ready for long-term storage or industrial reuse.
More work to do in 2023
If all works well, carbon absorption and extraction units will be installed towards the end of 2023, along with a modification of the liquefaction systems to cater for the deck tanks.
Over the next two years, a comprehensive carbon capture and storage facility will operate alongside the existing exhaust gas scrubbing and cleaning systems on the Eos, providing a constant stream of live data.
Wartsila said in October that it was initially targeting a 70% reduction in CO2 exhaust emissions.
The Clipper Eos has been time chartered by Marubeni Corp in Japan since delivery.
The Japanese company said it is committed to cooperating with Solvang and Wartsila to allow them to carry out tests and install relevant equipment on the ship.
