Onboard Carbon Capture System Market Report 2026

The onboard carbon capture system market size has grown rapidly in recent years. It will grow from $1.3 billion in 2025 to $1.47 billion in 2026 at a compound annual growth rate (CAGR) of 13.3%. The growth in the historic period can be attributed to growing maritime emission regulations, increasing pressure to decarbonize shipping fleets, rising adoption of exhaust treatment systems, expanding focus on low-carbon maritime operations, increasing awareness of environmental compliance.

The onboard carbon capture system market size is expected to see rapid growth in the next few years. It will grow to $2.41 billion in 2030 at a compound annual growth rate (CAGR) of 13%. The growth in the forecast period can be attributed to increasing global carbon reduction mandates, rising investment in onboard decarbonization technologies, growing adoption of retrofittable carbon capture solutions, expanding deployment of large vessel carbon capture pilots, increasing focus on carbon intensity reduction targets. Major trends in the forecast period include advancements in compact capture technologies, innovations in marine carbon dioxide storage systems, developments in energy-efficient absorption materials, research and development in solvent and sorbent chemistry, progress in modular onboard capture designs.

The growing adoption of carbon capture technologies in transport and mobile sources is expected to drive the expansion of the onboard carbon capture system market in the coming years. Transport carbon capture adoption refers to the use of systems and processes that capture carbon dioxide emissions directly from vehicles, ships, or mobile power units at the point of generation to reduce greenhouse gas emissions. Adoption of carbon capture technologies in transport and mobile sources is increasing due to tightening global emission standards and decarbonization targets that require operators to reduce tailpipe CO₂ emissions while continuing to operate existing vehicle fleets. Onboard carbon capture systems support transport and mobile carbon capture efforts by enabling the development and deployment of CO₂ capture technologies that can be integrated into mobile emission sources to meet regulatory requirements and emissions reduction goals. For instance, in March 2024, according to the International Energy Agency, a France-based intergovernmental organization, global carbon dioxide capture capacity planned for 2030 increased by 35% in 2023, while storage capacity rose by 70%, bringing total capture potential to over 430 million tonnes per year and storage capacity to around 620 million tonnes of CO₂ annually. Therefore, the increasing adoption of transport carbon capture technologies is driving the growth of the onboard carbon capture system market.

The rising demand for emissions reduction in shipping and aviation is also expected to propel the growth of the onboard carbon capture system market going forward. Demand for emissions reduction refers to the increasing global emphasis on lowering greenhouse gas emissions from sectors that significantly contribute to climate change, including transportation industries such as shipping and aviation. This demand is growing as international regulations and climate commitments require operators to reduce emissions, while customers and investors increasingly favor cleaner and more sustainable transport solutions. Onboard carbon capture systems support emissions reduction in shipping and aviation by providing technologies that capture CO₂ directly at the point of emission from vessels and aircraft, helping operators comply with stricter environmental targets. For instance, in July 2023, according to the International Maritime Organization, a UK-based United Nations specialized agency, the 2023 IMO Strategy on the Reduction of GHG Emissions from Ships set targets to cut carbon intensity by at least 40% by 2030, up from 35% in 2022, and to achieve net-zero greenhouse gas emissions around 2050, highlighting a year-over-year increase in ambition for decarbonizing the shipping sector. Therefore, the growing demand for emissions reduction in shipping and aviation is driving the growth of the onboard carbon capture system market.

Major companies operating in the onboard carbon capture system market are concentrating on the development of innovative solutions, such as commercially available onboard carbon capture and storage (CCS) systems for ships, to reduce CO₂ emissions at the point of combustion, support regulatory compliance, and advance maritime decarbonization. Commercial onboard CCS systems are technologies that capture carbon dioxide directly from vessel exhaust streams, store it onboard for later offloading or utilization, and allow shipowners to lower emissions without immediately transitioning to alternative fuels. For example, in May 2025, Wärtsilä, a Finland-based marine technology company, introduced its commercially available onboard carbon capture solution. The system was validated through a full-scale installation trial onboard the Clipper Eris ethylene carrier and is designed to cut vessel CO₂ emissions by up to 70% while integrating smoothly with conventional fuel engines and existing exhaust treatment systems. This launch represents a major technological advancement by bringing operational CCS capabilities to commercial vessels, bridging pilot-scale demonstrations with real-world deployment, and delivering a scalable and efficient solution for reducing maritime emissions.

Note that the outlook for this market is being affected by rapid changes in trade relations and tariffs globally. The report will be updated prior to delivery to reflect the latest status, including revised forecasts and quantified impact analysis. The report’s Recommendations and Conclusions sections will be updated to give strategies for entities dealing with the fast-moving international environment.

Tariffs are influencing the onboard carbon capture system market by increasing costs of imported compressors, capture units, storage cylinders, filtration modules, and monitoring electronics used in marine installations. ship operators in europe and north america are most affected due to reliance on imported specialized equipment, while asia-pacific faces cost pressure on shipbuilding and retrofit projects. these tariffs are increasing capital expenditure and slowing early adoption. however, they are also driving localized system assembly, regional engineering partnerships, and investment in domestic marine decarbonization technologies.

An onboard carbon capture system is an integrated technology installed directly on ships or marine vessels to capture carbon dioxide emissions generated during fuel combustion. It works by extracting carbon dioxide from engine exhaust gases, compressing it, and safely storing it onboard for later offloading at port facilities. These systems enable the maritime industry to reduce greenhouse gas emissions without requiring immediate modifications to existing vessel engines or fuel types.

The primary components and systems of onboard carbon capture systems include capture units, compressors and liquefaction units, storage cylinders, and filtration systems. Capture units refer to system elements designed to extract and isolate carbon dioxide from emission sources for storage or utilization. The services include installation, maintenance, retrofitting, monitoring, engineering consulting, system integration, and testing and inspection. The vessel types include commercial cargo ships, passenger ships, tankers, and offshore support vessels, and they serve key end-user industries such as shipping and maritime, aviation, freight and logistics, energy and utilities, and oil and gas.
