Maritime onboard carbon capture progress

In late July 2026 Singapore's Global Centre for Maritime Decarbonisation reported that its Project CAPTURED achieved two regulatory breakthroughs. The captured CO₂ was recognised under the EU Emissions Trading System, allowing verified tonnes to be deducted from required allowances, and the International Maritime Organization gave in‑principle support to carbon mineralisation as a permanent storage route. The pilot demonstrated a full value chain—from onboard capture to ship‑to‑ship off‑load, land transport and conversion into stable mineral products—while achieving a 7.9 % net greenhouse‑gas reduction.

A week later reporting highlighted that onboard carbon capture and storage (OCCS) systems were moving toward commercial deployment. A full‑scale installation on the Solvang ethylene carrier Clipper Eris captured about 50 tonnes of CO₂ per day, removing roughly 70 % of exhaust emissions. Similar units are being fitted to new gas carriers under construction for delivery in 2026‑27, with estimated capture costs of $54‑76 per tonne. The coverage noted remaining technical and regulatory challenges, including energy demand, off‑loading logistics and full IMO recognition.

Together the snapshots trace the transition from regulatory acceptance of maritime carbon capture to its scaling in commercial vessels, underscoring both progress and the hurdles that remain.
