해양 이산화탄소 제거 시장 기회, 성장 촉진요인, 업계 동향 분석 및 예측(2026-2035년)

The Global Ocean Carbon Dioxide Removal (CDR) Market was valued at USD 730 million in 2025 and is estimated to grow at a CAGR of 19.9% to reach USD 4.43 billion by 2035.

The market has historically been dominated by nature-based blue carbon approaches, largely centered on mangrove and seagrass restoration, which operated with limited commercial infrastructure and without a unified certification system. Since 2022, the sector has undergone a structural transformation as engineered ocean carbon removal technologies have begun to demonstrate measurable carbon sequestration results through verified field deployments. The industry is now transitioning from research-led funding models toward commercially structured carbon removal delivery contracts. Verified carbon removal has become a critical requirement for market participation, with independent registry validation emerging as a key benchmark for buyer confidence. Operators that achieve certified issuance are increasingly able to secure higher pricing and longer-term agreements compared to non-verified participants. Although ocean-based carbon removal credits are not yet part of compliance markets, maritime stakeholders are actively developing early-stage procurement strategies in anticipation of future regulatory inclusion. Large shipping operators have already initiated long-term offtake arrangements, reflecting expectations of eventual integration into compliance frameworks. Growing corporate preference for high-integrity, durable carbon removal solutions continues to reshape demand across the ocean CDR ecosystem, reinforcing the transition toward verified, technology-enabled removal pathways.

Ocean alkalinity enhancement (OAE) accounted for 29.2% share and is projected to grow at a CAGR of 21.6% through 2035. This approach increases the ocean's natural carbon absorption capacity by introducing alkaline mineral compounds such as calcium- and magnesium-based materials into seawater, thereby strengthening bicarbonate buffering processes and enhancing long-term carbon storage efficiency.

The corporate voluntary carbon purchasers represented 38% share and is expected to grow at a CAGR of 21.2% through 2035. This category includes multinational corporations across technology, aviation, financial services, and consumer industries that are increasingly investing in ocean-based carbon removal credits to meet voluntary climate commitments. Market demand is shifting toward high-quality, verified carbon removal credits, with buyers paying between USD 200-400 per tonne to secure durable, high-integrity carbon offsets that demonstrate additionality and long-term permanence.

North America Ocean Carbon Dioxide Removal (CDR) Market held 39.4% share in 2025 and is projected to grow at a CAGR of 18.5% during 2035. The United States represents the dominant contributor within the region, supported by strong federal research initiatives and funding programs focused on carbon removal innovation. Government-backed efforts aimed at reducing removal costs and expanding measurement, reporting, and verification capabilities continue to accelerate technology development and commercialization across the region.

Major companies operating in the global ocean carbon dioxide removal industry include Captura, Carboniferous, CarbonRun, Ebb Carbon, Equatic, Gigablue, Heimdal, Kelp Blue, Ocean Visions, Inc., Planetary Technologies, Seafields Solutions Ltd., SeaO2, SOS Carbon, Vesta, and Vycarb. Companies operating in the ocean carbon dioxide removal market are strengthening their competitive position by advancing technology development, expanding pilot-scale deployments, and securing long-term offtake agreements with corporate buyers. Many organizations are investing heavily in measurement, reporting, and verification systems to ensure credibility and compliance with emerging registry standards. Strategic collaborations with research institutions, maritime operators, and climate-focused organizations help accelerate technology validation and commercial scaling. Companies are also focusing on cost reduction through process optimization, materials innovation, and scalable deployment models to improve economic viability.
