Global Centre for Maritime Decarbonisation (GCMD) on Wednesday (21 July) said Project CAPTURED has achieved two regulatory milestones that strengthen the commercial case for onboard carbon capture and storage (OCCS). This comes following its world’s first demonstration of an end-to-end value chain for onboard captured and liquefied CO2 (LCO2). Completed in June 2025, the pilot showed that CO2 captured onboard a vessel can be offloaded ship-to-ship, transported overland and permanently bound through carbon mineralisation—a process that converts captured CO₂ into stable materials for industrial use. The CO2 captured onboard during Project CAPTURED has been formally recognised for compliance under the European Union Emissions Trading System (EU ETS). This means the verified tonnage of captured CO2 can be deducted from emissions requiring the surrender of EU Allowances (EUAs). To qualify for this recognition, the CO2 must be chemically bound permanently in eligible products. Project CAPTURED demonstrated that CO2 captured onboard vessels can meet this requirement through carbon mineralisation. The data and learnings from the same demonstration formed the basis of a proposal submitted to MEPC 84. This proposal received in-principle support from the International Maritime Organization (IMO) for recognising carbon mineralisation as a form of permanent CO₂ storage. Complementing geological sequestration, which is already accepted by the IMO, this recognition broadens the downstream options for CO2 captured onboard vessels, and supports the development of maritime carbon value chains. Beyond providing a permanent storage pathway, carbon mineralisation also creates the potential for captured CO2 to serve not only as a waste stream requiring permanent storage, but also as a feedstock for industrial applications through carbon mineralisation, extending emissions reductions beyond the shipping value chain.
