Ocean Rainforest, a company aiming to fight climate change through large-scale seaweed farming, has launched an 86-acre open-ocean seaweed farm off the coast of Santa Barbara, California. The farm is part of a research initiative to test seaweed's potential to absorb carbon and replace petroleum-based products. Backed by $22 million in funding from U.S. and European governments and venture capital, the project represents a significant leap in size for U.S. seaweed farming.
Despite promising potential, the U.S. seaweed industry faces several challenges. Funding has significantly dropped, from $100 million in 2022 to $8 million in 2024. Regulatory hurdles, the high cost of farming equipment, and declining retail prices for seaweed-based products complicate expansion. In contrast, European and Asian seaweed industries benefit from government support, making it difficult for U.S. farms to compete.
However, experts believe seaweed's versatility—offering benefits for food, animal feed, and carbon sequestration—can still drive the industry's growth, despite the current slowdown. Large-scale open-ocean farms like Ocean Rainforest's could potentially help decarbonize industries while fulfilling environmental goals. However, concerns about environmental impacts, such as threats to native kelp forests, remain key considerations for the future of large-scale seaweed farming.
