Reference of companies (key players) — what they do / why they matter
Wärtsilä — developed a full-scale onboard carbon capture system for ships (amine absorption-based flowsheets; pre-conditioning → absorption → desorption → liquefaction → storage). Positioned as an integrated supplier for merchant vessels.
Langh Tech — launched an onboard carbon capture system and has announced installations for several bulk carriers (commercial rollout activity).
Seabound — deployed a compact OCC unit on a commercial cement carrier (early commercial deployment / demonstration).
Shanghai Qiyao / SMDERI-QET (example from pilot reports) — supplier of OCCS used in China pilot projects (shows OEMs/region-centric suppliers are emerging).
Technology & equipment suppliers (examples) — DESMI (pumps & flow systems supporting OCC solvent loops), other marine pump/heat-exchange vendors link into systems. These supply-chain players are essential for integration.
Recent Development
First full-chain maritime pilot(s) completed (China, mid-2025) demonstrating capture → ship-to-ship transfer → truck offload → downstream processing, validating the end-to-end value chain.
Several vendors moved from lab/pilot to commercial demos and first installations in 2024–2025 (Wärtsilä full-scale product, Langh Tech rollouts, Seabound commercial unit). These transitions indicate the tech is entering early commercialisation.
Drivers
Regulatory pressure & IMO activity pushing shipping to decarbonize (workplans and guidelines emerging for OCC).
Decarbonization deadlines and corporate net-zero targets from charterers and cargo owners who seek emission reductions now.
Pilot successes that prove chain viability (capture → transfer → storage/use) reduce perceived risk for adoption.
Restraints
High CAPEX and OPEX (energy penalty, solvent/vessel weight/volume impacts, retrofit complexity).
Operational complexity and safety/regulatory uncertainty (handling and storage of captured CO₂ onboard; IMO/flag/state rules still evolving).
Regional segmentation analysis
Asia Pacific: rapid pilot activity and early deployments (China pilots cited), strong growth potential due to large shipping fleets and industrial CO₂ handling infrastructure.
Europe: vendor R&D and pilot programmes (Wärtsilä, Langh Tech, Seabound activities; regulatory push from EU and North Sea CCS hubs).
North America / else: project interest around coastal hubs and potential ship-to-port CO₂ chains; adoption depends on proximity to CO₂ transport & storage facilities. (Regional uptake correlates strongly with CO₂ storage/terminal availability.)
Emerging Trends
Compact, modular units that minimize footprint & can be retrofitted.
Integration with value chains (ship-to-ship / ship-to-shore CO₂ transfer demonstrations) — making captured CO₂ useful or available for storage.
New solvent/sorbent technologies and energy-efficient process variants as vendors seek to reduce energy penalty and volumes.
Top Use Cases
Maritime merchant vessels (bulk carriers, tankers, cement carriers, container ships) — immediate focus.
Onshore/offshore industrial vessels (e.g., vessels serving industrial clusters where CO₂ can be offloaded to storage).
Aviation & heavy road transport (long-haul trucks) — conceptually possible but much earlier stage; main commercial activity is in shipping today.
Major Challenges
Scale & weight constraints for ships — storing liquid/gaseous CO₂ and capture equipment consumes valuable space and adds weight.
Energy penalty (capture requires heat/electric power) — impacts fuel consumption and may reduce net GHG benefit if not powered from low-carbon sources.
Regulation & liability for handling CO₂ at sea and during transfer — IMO/flag/state protocols still under development.
Attractive Opportunities
First-mover advantage for shipowners/charterers offering lower-emission shipping to attract premium cargo.
Integration with port/CO₂ hub development (co-locating OCC adoption with nearby CO₂ export / storage infrastructure reduces logistics cost).
Service & retrofit market (engineering, solvent supply, CO₂ logistics) — recurring revenue for suppliers and ports.
Key factors of market expansion
Availability of CO₂ transport & storage hubs (ports, pipeline networks, permanent storage sites).
Economic incentives / carbon pricing / ETS inclusion that improve project IRR for OCC installations.
Proven, lower-energy capture technologies and modular designs to simplify retrofits.
Clear IMO/flag/port regulations and standardized ship-to-shore transfer protocols to reduce legal/operational barriers.
