根据 Stratistics MRC 的数据,全球碳捕获海洋藻类养殖市场预计在 2025 年达到 17.6 亿美元,到 2032 年将达到 50.1 亿美元,预测期内的复合年增长率为 16.1%。
碳捕获海洋藻类养殖是一种新兴的气候解决方案,利用大规模养殖海藻和微藻类来捕获大气和海洋中的二氧化碳。藻类的生长速度比陆地植物快很多倍,而且无需人工肥料、淡水或耕地。它们透过光合作用将二氧化碳转化为生质,可用作肥料、生质燃料、动物饲料和生质塑胶。它们还可以将部分捕获的碳储存在深海沉积物中。除了降低温室气体浓度外,此策略还能促进海洋生物多样性,透过吸收过剩营养物质改善水质,并为资源密集型农业提供永续的替代方案。
根据《海洋科学前沿》报导,大型藻类(海藻)群落排放的碳中约有 25%(相当于净初级生产力的约 43%)被封存在大陆棚沉积物或深海中,从长远来看,可能有效地蕴藏量碳。
碳封存潜力大
海洋藻类,尤其是海藻,可以人工培育并用于碳捕获,这是实现碳捕获的最快生物途径之一。在适当的条件下,海洋藻类每天可长至60厘米,吸收二氧化碳的速度远超过陆地植物。一些研究表明,某些物种每英亩土地吸收的二氧化碳量是森林的20倍。有些海洋藻类会脱落并沉入深海,阻止碳在数百年内释放到大气中。此外,海洋藻类养殖的生长潜力使其成为可行的自然气候解决方案。由于它不需要昂贵的技术,因此比人工碳捕获更经济、生态学永续。
维护和营运成本高
虽然海洋藻类养殖所需的基础设施比人工碳捕获更少,但大规模营运需要大量的资金和营运成本。安装锚碇系统、能够抵御恶劣海洋条件的捕捞设备以及海上养殖结构的成本都很高。持续的维护,例如修復风暴损坏、更换渔网和防止生物污损,也会增加成本。此外,加工和干燥生物质需要消耗大量能源,尤其是在养殖场远离加工厂的情况下。如果没有大量的补贴或强大的碳信用市场,这些高昂的成本可能会使短期内营运变得不经济。
技术发展和海水养殖的成长

According to Stratistics MRC, the Global Carbon Capture Marine Algae Farming Market is accounted for $1.76 billion in 2025 and is expected to reach $5.01 billion by 2032 growing at a CAGR of 16.1% during the forecast period. Carbon capture marine algae' farming is an emerging climate solution that uses large-scale cultivation of seaweed and microalgae to absorb carbon dioxide from the atmosphere and ocean. Algae don't need artificial fertilizers, freshwater, or arable land to grow, and they frequently do so many times faster than land plants. They use photosynthesis to turn CO2 into biomass, which can be harvested for fertilizers, biofuels, animal feed, and bioplastics. They can also store some of the carbon they capture in deep ocean sediments. In addition to lowering greenhouse gas concentrations, this strategy fosters marine biodiversity, enhances water quality by absorbing surplus nutrients, and provides a sustainable substitute for resource-intensive farming.
According to Frontiers in Marine Science, around 25% of the carbon exported from macroalgal (seaweed) stands-which represents approximately 43% of their net primary production-is sequestered in continental shelf sediments or the deep sea, signifying effective long-term carbon burial potential.
Outstanding potential for sequestering carbon
The cultivation of marine algae, especially seaweed, provides one of the quickest biological routes for capturing carbon. With the right conditions, seaweed can grow up to 60 cm per day and absorb CO2 at rates much higher than those of terrestrial plants. According to some studies, some species can absorb up to 20 times as much CO2 per acre as forests. Parts of the seaweed separate and sink to deep ocean layers, preventing the carbon from being released back into the atmosphere for centuries. Additionally, seaweed farming's capacity to grow makes it a viable natural climate solution. It is a more economical and ecologically sustainable method than engineered carbon capture because it doesn't require costly technology.
High maintenance and operational expenses
Large-scale operations still need a substantial amount of capital and operating expenses, even though marine algae farming requires less infrastructure than engineered carbon capture. Installing mooring systems, harvesting equipment that can withstand severe marine conditions and offshore cultivation structures come at a cost. Costs are increased by ongoing maintenance, which includes fixing storm-related damage, changing nets, and preventing biofouling. Biomass processing and drying can also require a significant amount of energy, particularly if farms are situated far from processing plants. These high costs can render operations short-term economically unfeasible in the absence of significant subsidies or a strong carbon credit market.
Technological development and the growth of offshore farming
Deeper offshore waters, where competition for space is less intense and growth conditions may be ideal, are becoming viable for seaweed cultivation owing to developments in aquaculture engineering, robotics, and marine monitoring. Autonomous seeding, harvesting, and monitoring systems can increase yields while lowering labor costs. The best nutrient-rich sites for optimal productivity can be found with the aid of data-driven site selection employing AI and satellite imagery. Additionally, offshore expansion creates multipurpose ocean spaces by opening up co-location opportunities with other marine industries, like offshore wind farms. The scalability of seaweed farming could be significantly increased by these developments, increasing the economic viability of large-scale carbon capture from marine algae.
Effects of climate change on ocean conditions
Ironically, seaweed farming aims to counteract the very effects of climate change, like rising sea temperatures, changing nutrient patterns, and increased ocean acidification, which directly threaten farm productivity. The temperature and salinity tolerances of many seaweed species that are farmed for commercial purposes are limited; extended heat waves can impede growth or result in mass die-offs. While typhoons and other extreme weather events can destroy infrastructure, altered ocean currents can decrease the availability of nutrients. The long-term stability and scalability of marine algae farming operations may be restricted by climate variability in the absence of genetic diversification, adaptive farming methods, and careful site selection.
The COVID-19 pandemic caused both short-term disruptions and long-term opportunities in the carbon capture marine algae farming market. Harvest and cultivation cycles were delayed in many areas due to supply chain disruptions, lockdowns, and port closures that made it difficult to obtain seeds, farming equipment, and processing facilities. Operations were further limited by a labor shortage, especially in offshore farms that needed experts to maintain them. Because of lower consumer spending, there was a brief drop in demand for some seaweed-derived products, such as cosmetics and upscale foods. The pandemic, however, also heightened interest in resilient, sustainable food systems and climate solutions, which resulted in more government funding, investment, and research into marine algae farming as a component of green recovery plans.
The macroalgae segment is expected to be the largest during the forecast period
The macroalgae segment is expected to account for the largest market share during the forecast period because of its adaptability to large-scale offshore cultivation, scalability, and quick growth rates. Often called seaweed, macroalgae are species that can reach lengths of several feet in a matter of weeks, such as kelp, red algae, and brown algae. These species can be grown without the use of artificial fertilizers, freshwater, or arable land because they absorb significant amounts of CO2 during photosynthesis. Their commercial appeal is further enhanced by their versatility, catering to markets like carbon credits, fertilizers, animal feed, biofuels, and bioplastics. Significant ecological advantages of large-scale macroalgae farms include lowering ocean acidification and enhancing marine biodiversity.
The photobioreactors segment is expected to have the highest CAGR during the forecast period
Over the forecast period, the photobioreactors segment is predicted to witness the highest growth rate because of their capacity to give algae regulated, highly effective growing conditions. In contrast to open pond systems, photobioreactors shield cultures from pollutants, contamination, and weather variations, allowing for reliable production all year long with the best possible light, nutrient, and CO2 supply. For use in carbon sequestration projects, biofuels, pharmaceuticals, and nutraceuticals, this leads to increased biomass yields and improved quality. Additionally, the technology facilitates the cultivation of high-value strains of microalgae that are challenging to cultivate in open systems. The rapid adoption and global expansion of photobioreactor systems is being driven by the growing demand for high-purity algae products and precision cultivation.
During the forecast period, the Asia Pacific region is expected to hold the largest market share, driven by its long-standing aquaculture traditions, long coastlines, and ideal climate. With the help of government subsidies, sophisticated farming methods, and robust domestic and export demand, nations like China, Indonesia, South Korea, and Japan are world leaders in the cultivation of seaweed. Large-scale operations that make a substantial contribution to global carbon sequestration efforts are made possible by the region's abundance of nutrient-rich waters and reduced production costs. Furthermore, Asia-Pacific is the leading center for the sector's environmental impact and commercial growth due to its strong processing infrastructure, wide range of markets for algae-based products, and active involvement in sustainable aquaculture initiatives.
Over the forecast period, the North America region is anticipated to exhibit the highest CAGR, driven by an increase in funding for environmentally friendly aquaculture, a surge in interest in blue carbon initiatives, and favorable legislative frameworks for mitigating the effects of climate change. In order to maximize ocean space, there are more pilot projects and commercial-scale farms in the U.S. and Canada. These are frequently combined with offshore wind farms or other marine industries. Technological developments like automated harvesting and precision monitoring systems are speeding up scalability, and the market for carbon credits, bioplastics, and algae-based biofuels is growing quickly. North America's status as a high-growth region is further enhanced by robust research partnerships among government agencies, startups, and universities.
