Report Overview

The Global Microalgae Market size is expected to be worth around USD 1730.6 Million by 2034, from USD 794.2 Million in 2024, growing at a CAGR of 8.1% during the forecast period from 2025 to 2034. In 2024, North America held a dominant market position, capturing more than a 43.90% share, holding USD 328.8 Million revenue.

Microalgae form a fast-growing niche within the wider algae industry, supplying high-value products such as nutraceuticals, aquafeed ingredients, pigments, biofertilizers and, increasingly, low-carbon fuels. FAO estimates that global algae production (seaweeds plus microalgae) reached 37.8 million tonnes in 2022, with 97% coming from aquaculture and almost all of it produced in Asia.

Industrial microalgae volumes are still modest compared with seaweeds, but the sector is scaling. Recent scientific reviews place global microalgae production capacity at roughly 20,000–30,000 tonnes of dry biomass per year, with an estimated market value of around USD 977.3 million for microalgae-based products. A separate assessment reports about 56,465 tonnes of microalgae biomass produced in 2019, heavily concentrated in China, underscoring the dominance of Asian producers in large-scale cultivation. The U.S. Department of Energy also notes that a commercial microalgae industry exists globally with production near 60,000 tons per year, mainly for food and aquaculture markets.

• Demand fundamentals are being reshaped by the global decarbonization agenda. The International Energy Agency (IEA) reports that energy-related CO₂ emissions rose 1.1% in 2023 to a record 37.4 billion tonnes, despite strong growth in clean energy. In parallel, the IEA expects total biofuel demand to increase 23% to 200 billion litres by 2028, with advanced biofuels playing a growing role. In its Net Zero scenario, biofuels from wastes, residues and non-food crops must supply over 40% of total biofuel demand by 2030, positioning microalgae as a strategic feedstock candidate.

Beyond fuels, microalgae also fit into the broader bio-inputs and circular-economy agenda. A 2024 study on microalgae-based agricultural inputs estimates that microalgal plant stimulants alone could reach about EUR 2.5 billion in sales, within a global biostimulants market projected at roughly EUR 5.5 billion.

Government initiatives are increasingly explicit. The European Commission’s communication “Towards a Strong and Sustainable EU Algae Sector” projects European seaweed demand rising from about 270,000 tonnes in 2019 to 8 million tonnes by 2030, with a potential market value of EUR 9 billion for algae-based products and services. A recent EU factsheet indicates that the Union invested roughly EUR 559 million between 2014 and 2023 into 219 algae-related projects, spanning sustainable food, marine restoration, biofuels and bioplastics. These programs create de-risked pathways and shared infrastructure that microalgae players can leverage.

Emerging Trends

Microalgae Moving into Mainstream Food, Feed and Blue-Bioeconomy Systems

One clear trend in the microalgae space is that it is no longer seen only as a lab curiosity or a future biofuel. It is being pulled into the real heart of the food system and the broader blue bioeconomy. The latest FAO figures show that global fisheries and aquaculture production hit 223.2 million tonnes in 2022, including 37.8 million tonnes of algae. Algae are not a side story anymore; they sit inside the same statistics as fish and shrimp, and that changes how policymakers and industry think about microalgae too.

What really stands out is how industrial algae cultivation has become normalised in aquaculture. Algae production is now overwhelmingly farmed, not harvested from the wild. An FAO-based analysis notes that about 37.8 million tonnes of algae in 2022 came mainly from aquaculture, while wild collection contributed just around 1.3 million tonnes. Another summary highlights that roughly 97% of global algae production now comes from aquaculture. This huge base of cultivated algae – mostly seaweed today – makes it much easier to imagine microalgae scaling within existing farming, processing and logistics chains.

At the same time, food and nutrition pressures are pushing the world to look hard at new protein and micronutrient sources. UN agencies estimate that about 8.2% of the global population – roughly 673 million people – faced hunger in 2024, and around 2.3 billion people experienced moderate or severe food insecurity. When you put those numbers next to microalgae’s high protein content, omega-3 oils and vitamins, the trend becomes obvious: companies are moving microalgae into functional foods, fortified staples, alternative seafood, and specialty ingredients rather than betting only on fuel.

Government strategies in advanced economies now talk about algae as a strategic resource for food, feed and climate, not just a marine oddity. The European Commission’s communication “Towards a strong and sustainable EU algae sector” draws heavily on work by the Seaweed for Europe coalition, which expects European demand for seaweed to rise from about 270,000 tonnes in 2019 to 8 million tonnes by 2030, unlocking up to EUR 9 billion in annual market value and creating roughly 85,000 jobs.

This policy push also reframes microalgae as part of a broader “services plus products” model. The EU documents highlight algae’s role in wastewater treatment, nutrient removal and carbon management, alongside food and feed markets. That is exactly where many microalgae pilots are heading: co-located with aquaculture farms, food factories or industrial plants, using CO₂ and nutrient-rich effluents to grow biomass that can be sold as ingredients or bio-inputs. It is a practical, low-waste narrative that resonates with regulators, retailers and consumers looking for real climate solutions rather than abstract promises.

Drivers

Rising Demand for Sustainable Food and Feed Drives the Microalgae Industry

A major driving force behind the microalgae industry is the world’s search for sustainable food and feed ingredients. Global fisheries and aquaculture production reached 223.2 million tonnes in 2022, of which aquaculture alone produced 130.9 million tonnes valued at USD 312.8 billion. As aquaculture keeps expanding, producers are under pressure to find new, low-impact sources of protein, lipids and pigments, and microalgae fits this need very well.

Fish and other aquatic foods are becoming more central in people’s diets. FAO reports that global annual per-capita apparent consumption of aquatic animal foods increased from 9.1 kg in 1961 to an estimated 20.7 kg in 2022. This rapid rise means the food system must deliver more high-quality protein and omega-3s without putting unsustainable pressure on wild fish stocks. Microalgae can supply these nutrients directly, or indirectly as feed ingredients in fish farming, while using less land and avoiding competition with traditional crops.

Food security adds another layer of urgency. Latest UN and FAO estimates suggest about 8.2% of the global population – roughly 638–720 million people – faced hunger in 2024. At the same time, healthy and diverse foods remain too expensive for many households. Microalgae-based ingredients, such as protein concentrates, DHA-rich oils, and fortified foods, are seen by policymakers as part of a broader toolkit to improve diet quality without further stressing land and freshwater resources.

Government strategies are starting to convert this need into concrete support. In its communication “Towards a Strong and Sustainable EU Algae Sector,” the European Commission projects that European demand for algae (including microalgae) could grow from about 270,000 tonnes in 2019 to 8 million tonnes by 2030, with a potential market value of EUR 9 billion. An associated analysis suggests that this scaling could create around 85,000 jobs, remove large quantities of nitrogen and phosphorus from European seas, and help mitigate up to 5.4 million tonnes of CO₂ emissions each year.

Restraints

High Production Cost and Technical Complexity Hinder Microalgae Scaling

To begin with, growing microalgae at scale demands a lot of inputs: water, nutrients, controlled light or CO₂ supply, and careful management. According to a recent review, the energy and infrastructure requirements — such as pumping water, providing CO₂, maintaining light and temperature, then drying or dewatering the algae — make it difficult to achieve a positive energy balance under current systems. In fact, estimates suggest that cultivation plus harvesting and dewatering may account for 20–30% of the total production cost.

Another technical challenge is the complexity of cultivation systems. There are many ways to grow microalgae: open ponds (raceway ponds), closed photobioreactors (PBRs), hybrid systems, or even using wastewater. Each has trade-offs. Open ponds are cheaper to build but less productive, more prone to contamination, and sensitive to weather and sunlight. Closed PBRs can deliver higher and more stable yields, but they require much higher capital and operational costs, which again undermines economic viability.

• Harvesting and biomass recovery add further hurdles. Microalgae cultures are typically very dilute (e.g. around 1 gram per liter), which means to get 1 kg of dry biomass, a large volume of water must be processed. Harvesting — via centrifugation, filtration, flocculation, or dewatering — is energy intensive and expensive. Sometimes, even after all that, the yield of desired compounds remains low, or variable depending on species and cultivation conditions.

In short, while microalgae has enormous potential — as food, feed, pharmaceuticals, biofuels, carbon capture — the harsh reality is that producing it at industrial scale remains expensive, resource-intensive, and technically fragile. Until breakthroughs bring down the cost of cultivation, harvesting, drying and processing — or until policy incentives strongly offset those costs — many microalgae ventures will struggle to become commercially viable.

Opportunity

Microalgae as a High-Impact Opportunity for Future Food and Nutrition

A powerful growth opportunity for the microalgae sector lies in supplying sustainable food and protein in a world that is hungry for both nutrition and lower emissions. The FAO’s latest State of World Fisheries and Aquaculture shows that total fisheries and aquaculture output reached 223.2 million tonnes in 2022, including 37.8 million tonnes of algae and 130.9 million tonnes from aquaculture alone, valued at USD 312.8 billion. This huge food system is already used to handling aquatic biomass – microalgae can plug directly into this space with more efficient, climate-friendly products.

At the same time, the world is still struggling with hunger and poor diet quality, which makes nutrient-dense microalgae very attractive in policy discussions. According to the UN, about 8.2–8.3% of the global population – roughly 673 million people – faced hunger in 2024, while around 2.3 billion people experienced moderate or severe food insecurity. The 2025 Global Report on Food Crises adds that more than 295 million people in 53 countries suffered acute hunger in 2024. In this context, microalgae’s ability to deliver complete protein, omega-3 fatty acids, vitamins and pigments from relatively small areas of land and non-arable sites becomes a very real opportunity, not just a technological curiosity.

Governments are starting to treat algae – including microalgae – as a strategic food and protein resource, which further enlarges the growth window. In its communication “Towards a Strong and Sustainable EU Algae Sector”, the European Commission notes that European demand for algae could jump from around 270,000 tonnes in 2019 to 8 million tonnes by 2030, with the value of the European seaweed and algae market potentially rising from about EUR 840 million to EUR 9 billion over the same period. Much of this expected growth is linked to new foods, feeds, nutraceuticals and functional ingredients – exactly the areas where microalgae can shine.
