Onboard carbon capture is moving from pilot projects toward commercial shipping. A new market report from The Business Research Company sizes the sector at $1.30 billion in 2025 and expects it to hit $2.41 billion by 2030, a compound annual growth rate around 13%. The growth story is tied to tightening maritime emissions rules and shipowners looking for ways to cut CO2 without immediately switching fuels. The report highlights Wartsila's commercially available onboard capture system, tested on the Clipper Eris ethylene carrier, which claims up to 70% reduction in vessel CO2 emissions while working with existing engines and exhaust setups. Major names like Shell, TotalEnergies, Mitsubishi Heavy Industries, and MAN Energy Solutions are active in the space. The market is segmented by component, service type, vessel type, and end user, with chemical absorption, membrane separation, and cryogenic capture among the technology categories. Worth reading if you track shipping decarbonization or carbon removal tech. The numbers come from a vendor report rather than independent analysis, so treat the forecasts as directional.
