Onboard Carbon Capture System Market Global Report 2026

The onboard carbon capture system market size has grown exponentially in recent years. It will grow from $0.26 billion in 2025 to $0.32 billion in 2026 at a compound annual growth rate (CAGR) of 21.2%. The growth in the historic period can be attributed to increasingly stringent maritime emission regulations, growing pressure to decarbonize shipping fleets, rising adoption of exhaust treatment systems, expanding emphasis on low-carbon maritime operations, and increasing awareness of environmental compliance requirements.

The onboard carbon capture system market size is expected to see exponential growth in the next few years. It will grow to $0.67 billion in 2030 at a compound annual growth rate (CAGR) of 20.8%. The growth in the forecast period can be attributed to increasing global carbon reduction mandates, rising investments in onboard decarbonization technologies, growing adoption of retrofittable carbon capture solutions, expanding deployment of carbon capture pilot projects for large vessels, and increasing focus on carbon intensity reduction targets. Major trends in the forecast period include advancements in compact carbon capture technologies, innovations in marine carbon dioxide storage systems, development of energy-efficient absorption materials, increasing research and development in solvent and sorbent chemistry, and progress in modular onboard carbon capture designs.

The increasing adoption of carbon capture technologies in transport and mobile sources is expected to propel the growth of the onboard carbon capture system market going forward. Transport carbon capture adoption refers to the increasing use of systems and protocols that capture carbon dioxide emissions directly from vehicles, ships, or mobile power units at the point of generation to reduce greenhouse gas emissions. The increasing adoption of carbon capture technologies in transport and mobile sources is driven by tightening global emission standards and decarbonization targets that encourage operators to reduce tailpipe carbon dioxide emissions while continuing to operate existing vehicle fleets. The onboard carbon capture system market supports the adoption of carbon capture technologies in transport and mobile sources by developing and deploying carbon dioxide capture technologies that can be integrated with mobile emission sources to meet emissions targets and regulatory requirements. For instance, in March 2024, according to the International Energy Agency, a France-based intergovernmental organization, carbon dioxide capture capacity for 2030 increased by 35% in 2023, while storage capacity increased by 70%, bringing total capture potential to more than 430 million tonnes per year and storage capacity to approximately 620 million tonnes of carbon dioxide per year. Therefore, the increasing adoption of transport carbon capture technologies is driving the growth of the onboard carbon capture system market.

The increasing demand for emissions reduction in shipping and aviation is expected to drive the growth of the onboard carbon capture system market going forward. Emissions reduction demand refers to the growing global emphasis on lowering greenhouse gas emissions from sectors that make significant contributions to climate change, including transportation sectors such as shipping and aviation. The demand for emissions reduction in shipping and aviation is increasing as international regulations and climate targets increasingly require operators to reduce greenhouse gas emissions, while customers and investors are also demanding demonstrably cleaner transportation options. 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, enabling operators to meet increasingly stringent emissions targets. For instance, in July 2023, according to the International Maritime Organization (IMO), a UK-based United Nations specialized agency, the 2023 IMO Strategy on Reduction of GHG Emissions from ships established targets to reduce carbon intensity by at least 40% by 2030, compared with 35% in 2022, and achieve net-zero greenhouse gas emissions by around 2050, highlighting a clear year-over-year increase in ambition for decarbonization in the shipping sector. Therefore, the increasing demand for emissions reduction in shipping and aviation is driving the growth of the onboard carbon capture system market.

Key companies operating in the onboard carbon capture system market are focusing on developing innovative solutions, such as commercially available onboard carbon capture and storage systems for ships, to reduce carbon dioxide emissions at the point of combustion, support regulatory compliance, and advance maritime decarbonization. Commercial onboard carbon capture systems are technologies that capture carbon dioxide directly from vessel exhaust, store it onboard for later offloading or utilization, and enable shipowners to lower emissions without immediately switching to alternative fuels. For example, in May 2025, Wärtsilä, a Finland-based marine technology company, launched its commercially available onboard carbon capture solution. This system was validated through a full-scale installation trial onboard the Clipper Eris ethylene carrier and is designed to reduce vessel carbon dioxide emissions by up to 70 percent while integrating seamlessly with conventional fuel engines and existing exhaust treatment systems. This launch represents a significant technological advancement by bringing operational carbon capture and storage capability to commercial vessels, bridging trial-scale demonstrations with real-world deployment, and offering a scalable, efficient solution for maritime emissions reduction.
