Private investment in Europe’s blue economy is becoming more mainstream, according to a new European Commission report that details increasing interest from venture capital firms, private equity investors and corporate-backed funds.
The report, BlueInvest Investor Report 2026: The Next Wave of Blue Growth, identifies 159 private funds active in the EU blue economy. Of these, about €3 billion is tied to funds fully dedicated to ocean-related sectors, while a further roughly €11 billion comes from investors with partial exposure to the area, according to the Commission.
"More funds are entering the space, more capital is becoming available, and investor interest is clearly rising," the Commission said, announcing the findings.
"While challenges remain - especially in scaling companies and attracting later-stage funding - the direction of travel is clear. The blue economy is no longer seen as a niche, it is becoming a serious investment theme, with the potential to deliver both financial returns and long-term sustainability impact," it added.
The Commission said one of the clearest signs of momentum is the growth of dedicated “blue funds” targeting areas such as aquaculture, marine energy and ocean technology, complementing more conventional funding sources.
Venture capital firms currently make up the largest share of investors covered in the report, with many backing companies working in areas related to water, climate and sustainability, as well as explicitly ocean-focused businesses. The Commission argues this suggests the blue economy is increasingly being treated as part of a broader investment thesis rather than a category on its own.
At the same time, larger investors are beginning to take a closer look, especially in segments linked to infrastructure, energy and decarbonisation. Even so, the report says later-stage capital remains relatively scarce, a gap that could make it more difficult for companies to scale.
Despite the increased interest, the Commission also said the sector still appears "underfunded" relative to its commercial and environmental potential.
"If the ocean economy were a country, it would rank among the world’s five largest economies, with long-term growth potential projected to outpace global GDP," the report begins. "Yet, scientific assessments of planetary boundaries show that ocean-related thresholds, such as warming, acidification, biodiversity loss and nutrient pollution, are under severe pressure, threatening both ecological resilience and economic value creation," it notes, arguing that this means investment in ocean innovation is not only a "philanthropic" activity but "a way to safeguard our own ability to generate economic value in the long term."
To address this, the report includes sector-by-sector analysis covering aquaculture, fisheries, blue biotechnology, blue renewable energy, blue tech, ocean observation, shipping, ports and water management, while also highlighting businesses in the BlueInvest project pipeline.
The report surveyed investors on which areas within the blue economy held the greatest appeal, finding that shipping, shipbuilding and ports was the most popular category, with 46% of respondents identifying it as the sector with the strongest financial potential. Blue renewable energy followed at 41%, ahead of water management (38%) and blue biotechnology (36%), while aquaculture was selected by 33% of investors. Slightly further down the ranking were blue tech and ocean observation at 26%, environmental protection and regeneration at 23%, while coastal and marine tourism came in at 3%.
The report was produced for the European Commission by PwC Luxembourg and builds on previous investor reports released in 2023 and 2024. The full report can be accessed via the European Commission website.
