海洋二氧化碳去除市場機會、成長要素、產業趨勢分析及2026-2035年預測。

預計到 2025 年，全球海洋二氧化碳移除 (CDR) 市值將達到 7.3 億美元，並將以 19.9% 的複合年成長率成長，到 2035 年達到 44.3 億美元。

該市場歷來以基於自然的「藍碳」方法為主導，主要集中在紅樹林和海草的再生上，但商業基礎設施有限，統一的認證系統尚未建立。自2022年以來，隨著人工海洋碳去除技術透過檢驗的現場部署開始展現出可衡量的碳封存效果，該產業經歷了結構性轉型。目前，該行業正從以研究主導的資金籌措模式轉向以商業性構建的碳去除實施合約。檢驗的碳去除已成為市場參與企業的關鍵要求，而獨立註冊機構的檢驗正逐漸成為贏得買家信任的主要標準。與檢驗的參與者相比，已獲得認證碳權額度的營運商越來越能夠獲得更高的價格和更長期的合約。雖然基於海洋的碳去除碳權額度尚未納入合規市場，但海事相關人員正積極制定早期籌資策略，並著眼於未來的監管整合。大型航運公司已經開始簽訂長期啟動契約，旨在將其納入未來的合規框架。隨著企業越來越傾向於可靠且永續的碳去除解決方案，海洋碳去除生態系統的需求不斷重組，推動著向檢驗和技術驅動的去除途徑的轉變。

海洋鹼度增強（OAE）佔海洋總量的 29.2%，預計到 2035 年將以 21.6% 的複合年成長率成長。這種方法涉及向海水中引入鹼性礦物化合物，主要是鈣和鎂，以增強海洋的自然碳吸收能力，從而增強碳酸氫鹽的緩衝作用並提高長期碳儲存效率。

企業自願碳權購買者目前佔市場佔有率的38%，預計到2035年將以21.2%的複合年成長率成長。這個類別涵蓋了科技、航空、金融服務和消費品等行業的跨國公司，它們正在加大對海洋碳移除信用的投資，以履行其自願氣候行動承諾。市場需求正轉向高品質、檢驗的碳移除信用，購買者願意支付每噸200至400美元，以確保獲得持久可靠的碳抵消，並證明其具有額外性和長期永續性。

預計到2025年，北美海洋二氧化碳移除（CDR）市場將佔據39.4%的市場佔有率，並在2035年之前以18.5%的複合年成長率成長。美國是該地區最大的貢獻者，這得益於聯邦政府強力的研究舉措和專注於碳去除創新的資助計畫。政府主導的旨在降低去除成本和擴大測量、報告和檢驗（MRV）能力的各項舉措，持續加速全部區域的技術開發和商業化進程。

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.
