On Board Carbon Capture System Market to Reach USD 15.0 Billion | With CAGR of 21.1% During the Forecast Period of 2025 to 2035

The On-Board Carbon Capture System Market is emerging as a transformative solution in the global quest to decarbonize maritime transportation and achieve net-zero emission goals. As the shipping industry faces growing pressure to reduce greenhouse gas (GHG) emissions, innovative technologies like on-board carbon capture (OBCC) systems are becoming critical. These systems enable vessels to capture and store carbon dioxide (CO₂) directly from exhaust gases during operation, allowing continued use of existing fuel infrastructure while significantly reducing environmental impact.

Driven by tightening international regulations, growing sustainability initiatives, and technological advancements, the OBCC market is poised for rapid growth. This innovative approach offers a practical pathway for shipowners to comply with the International Maritime Organization’s (IMO) carbon intensity targets and future environmental mandates.

Market Drivers

Stringent Environmental Regulations by IMO and Other Bodies:

One of the strongest drivers of the On-Board Carbon Capture System Market is the tightening of global emission standards. The International Maritime Organization (IMO) aims to cut total annual GHG emissions from shipping by at least 50% by 2050 compared to 2008 levels. Additionally, new frameworks such as the IMO’s Energy Efficiency Existing Ship Index (EEXI) and Carbon Intensity Indicator (CII) are compelling ship operators to adopt advanced emission control technologies, including on-board carbon capture.

Growing Focus on Decarbonization in Maritime Sector:

The maritime industry accounts for approximately 3% of global CO₂ emissions, prompting governments, shipbuilders, and operators to seek cleaner alternatives. On-board carbon capture systems offer a transitional decarbonization method that can be implemented on both new and existing vessels without requiring complete fuel system overhauls.

Rising Fuel Consumption and Energy Transition Challenges:

While alternative fuels like hydrogen, ammonia, and methanol are being developed, their large-scale adoption remains constrained by cost, storage, and infrastructure challenges. OBCC technology allows ships to continue operating on conventional fuels while mitigating emissions, providing an effective interim solution until zero-emission fuels become widely accessible.

Corporate Sustainability Goals and ESG Commitments:

Shipping companies are increasingly integrating Environmental, Social, and Governance (ESG) principles into their business models. Implementing carbon capture aligns with corporate sustainability strategies, helping companies demonstrate compliance with environmental standards and appeal to eco-conscious investors and clients.

Technological and Economic Feasibility:

Continuous innovation in carbon capture materials, energy efficiency, and system miniaturization is improving the economic viability of OBCC systems. As technology costs decline and operational efficiency improves, adoption across commercial shipping segments—including tankers, bulk carriers, and container vessels—is accelerating.

Government and R&D Support:

Governments and research organizations are funding pilot projects and partnerships to test and scale on-board carbon capture technologies. These initiatives are fostering collaboration between shipbuilders, marine equipment manufacturers, and technology developers to refine system design and improve performance under real-world maritime conditions.

Technological Advancements

Integration of Advanced Capture Technologies:

On-board carbon capture systems leverage various chemical and physical processes—such as amine-based absorption, cryogenic separation, and membrane filtration—to capture CO₂ from exhaust gases. Recent innovations are improving capture efficiency, reducing energy consumption, and optimizing CO₂ compression and storage onboard.

Development of Lightweight and Compact Systems:

Shipboard installations require space-efficient and weight-optimized systems to maintain vessel balance and cargo capacity. Manufacturers are designing modular OBCC systems that integrate seamlessly with existing exhaust treatment setups, making retrofitting easier for older ships.

Use of Advanced Sorbents and Membrane Materials:

Research in next-generation sorbent materials, including solid amine and metal-organic frameworks (MOFs), is enabling higher CO₂ capture rates at lower operational costs. These materials are more durable, require less regeneration energy, and are suitable for long-duration marine operations.

Integration with Energy Recovery Systems:

To offset the energy penalty of carbon capture, OBCC systems are increasingly integrated with waste heat recovery units and hybrid propulsion systems. Utilizing waste heat from engines to regenerate capture materials enhances overall system efficiency and reduces fuel consumption.

Digitalization and Real-Time Monitoring:

Advanced digital control systems equipped with AI and IoT technologies are enhancing the monitoring and optimization of carbon capture operations. These systems allow operators to track capture efficiency, CO₂ storage levels, and energy use in real time, ensuring smooth and automated system performance.

CO₂ Storage and Offloading Innovations:

The captured CO₂ can be stored onboard in pressurized tanks until vessels reach port facilities where it can be offloaded for utilization or permanent storage. Companies are developing compact storage solutions and standardized interfaces for seamless CO₂ transfer between ships and port-based carbon management infrastructure.

Hybrid Integration with Alternative Fuels:

The future of OBCC lies in its compatibility with alternative fuels like LNG, methanol, or biofuels. Combined systems can drastically reduce both CO₂ and other pollutant emissions, positioning hybrid solutions as key enablers of maritime decarbonization.
