Capture on board. Regenerate in port.

An onboard carbon-capture system that absorbs CO₂ from main-engine exhaust at sea using a 30 % w/w aqueous MEA solution, stores the rich solvent on board, and regenerates it at port with industrial waste heat — so the shipowner's net capture under EU ETS and FuelEU equals the gross capture on board.

Onboard regeneration burns roughly €205 000/year of extra HFO on a 25 000 DWT reference vessel. Those emissions are attributed back to the same vessel under ETS and FuelEU — so the regulatory benefit erodes. The owner's net capture ends up below the gross. CAPCO2 moves regeneration to a port-side skid fed with industrial waste heat. The MEA travels; the carbon doesn't. Net capture equals gross.

A European shipowner running EU-fixed routes today faces three simultaneous, escalating pressures:

· EU ETS at 100 % from 2027 — every ton of CO₂ on intra-EU voyages is a direct cost.
· FuelEU Maritime (Reg. 2023/1805) GHG-intensity penalties scaling to 2040.
· CII · IMO MEPC operational rating that degrades residual value and charter employability.

For a single 25 000 DWT vessel, the combined 2025–2040 exposure is around €8 million. CAPCO2 cuts that exposure with no new fuel and no full retrofit.

TRL 6. A batch absorption-regeneration pilot was executed at the Port of Vigo in October 2025 under the PERTE Naval framework. Bureau Veritas witnessed and certified the campaign.

Demonstrated net capture: 42 kg/h, with 5–7 % deviation against the ProSim Plus simulation. The rig operated stably and reproducibly with zero mechanical, hydraulic or thermal incident.

An AiP covering three layers — concept, detail, and onboard integration — issued by Bureau Veritas. It is the class-society green light to advance toward full type approval and integration on a target vessel.

The reference engineering case is a 25 000 DWT vessel running 36 191 nm/year (163 days at sea), with a 850 m³ onboard MEA tank. The shipowner calculator runs the case for any vessel type and trade. For a vessel-specific feasibility study, contact us — willbö's marine team has been delivering structural, piping and integration retrofits since 2018.

willbö delivers pure CO₂ at the discharge interface. Downstream management of that CO₂ — geological storage, industrial utilisation, transport — is a separate market, served by third parties.

That boundary is deliberate: it keeps CAPCO2 commercially replicable at every European port. We are not a CO₂ logistics company, and we don't gate the technology on a specific downstream partner.

On the 25 000 DWT reference vessel:

· 3 635 t/year gross CO₂ captured
· 1 220 kg/h average capture rate
· GHG intensity from 77.09 to 42.91 gCO₂e/MJ (−44 %)
· Net / gross capture ratio 1.00

CAPCO2 is currently the only OCCS architecture that reaches 1.00 for the owner.

2026: PORTS 4.0 A1 start (resolution H2 2026); Horizon Europe CL5 submission (ZEWT + "New CO₂ Capture Technologies"); commercial talks with Spanish target shipowners.

2027: Port-Ready A2/A3 reaching TRL 9; CEF Transport application for port CO₂ reception infrastructure; formal OCCS recognition under FuelEU Maritime (EC · end 2027); first commercial installation signed.

2028 → 2030: Innovation Fund candidacy and progressive rollout. Addressable European niche of 1 344–1 836 vessels, 5 % penetration target.

Two steps:

1. Run the CAPCO2 calculator (90 seconds, no sign-up). Pick your vessel type, move the sliders for ETS price and capture rate, see your net benefit and payback window from 2027 to 2039 in your own numbers.

2. Book the exposure call. willbö will tell you, vessel by vessel, what doing nothing costs between 2027 and 2040 — and whether OCCS at zero net cost is the best decision your Board has to take this year.
