About 5 miles off the coast of Santa Barbara, California, an enormous swath of big kelp—Macrocystis pyriferia, which might develop almost 3 ft per day—sways slightly below the floor of one of many world’s first open-ocean seaweed farms.
Nonetheless in its analysis part, the 86-acre venture is operated by Ocean Rainforest, an organization that goals to combat local weather change by rising seaweed at scale: 1 million tons a year by 2030. Though an 86-acre terrestrial farm can be thought of boutique, the Ocean Rainforest plot, floating in sight of the Channel Islands, represents a big leap in dimension from the typical U.S. seaweed farm of 1 to 4 acres—and a brand new frontier for ocean farming.
Supported by $6.2 million in Collection A funding, for a complete of $22 million from U.S. and European governments, grants, and enterprise capital, Ocean Rainforest additionally operates seaweed farms within the Faroe Islands and Iceland that offer the animal-feed, fertilizer, and beauty industries. The corporate’s aim of considerably decarbonizing these industries—with seaweed, as an alternative of petroleum feedstocks, as uncooked materials—is dependent upon the success of this farm. Rising seaweed within the open ocean, with room to exponentially broaden, means the Ocean Rainforest crew is tackling learn how to anchor crops in a whole lot of ft of water, stand up to intense climate, and monitor a farm that lies many miles from shore.
As Ocean Rainforest continues its analysis, the broader U.S. seaweed business, nonetheless in its infancy, faces important challenges. A number of years of steady investment and scientific breakthroughs have helped it advance, however since 2023, funding has dropped precipitously, and so have retail costs for seaweed-based meals. Within the meantime, an absence of presidency steerage via regulation and laws makes it tough for farms to realize traction. Seaweed is a rare crop, providing a number of advantages to planetary and human health together with an array of business applications. But it surely’s truthful to say that proper now, the business is having rising pains.
The Funding Slowdown
In 2023, in accordance with Phyconomy, a database that tracks the seaweed economic system, seaweed funding within the U.S. abruptly started to sink, dwindling from a peak of about $100 million in 2022 to simply $8 million for 2024 thus far.

“We’re in what I name the ‘valley of disappointment,’” says Steven Hermans, who based Phyconomy. American buyers have turn out to be extra subtle about startup investments, together with in seaweed, he says. A couple of years in the past, he provides, “They didn’t know something, they usually have been like, ‘OK, we’ll toss a few million into this.’ Then, Everybody saved their cash of their pockets throughout excessive inflation . . . [and] folks realized . . . it’ll take a very long time to construct a marketplace for American-grown kelp. Now they’re asking higher questions, and that can in the end result in higher investments.”
However for some firms, that gained’t matter. Since Civil Eats started this reporting venture almost a yr in the past, two of the biggest and most well-known American kelp companies have gone underneath: Working Tide, a carbon capture company, and AKUA, maker of kelp burgers.
Based in 2017 by Marty Odlin, the Maine-based Running Tide was some of the well-funded kelp firms within the U.S. earlier than it shut down abruptly in June 2024. As its website stated, Working Tide aimed to construct “humanity’s working system for the ocean,” drawing down carbon by way of seaweed-inoculated wooden chips. Seaweed naturally absorbs carbon because it grows, however until it’s harvested, it decomposes and releases carbon again. The chips, then again, would sink to the deep ocean to decay, storing the carbon there for hundreds of years, according to Odlin. Working Tide’s income aim was to promote carbon removing credit to firms desirous about lowering their carbon footprint.
Working Tide garnered $54 million in Collection B investments, together with from Lowercarbon Capital, in 2022. In June of that yr, an article within the MIT Technology Review questioned Working Tide’s farming and enterprise practices. In the meantime, the corporate ready to relocate to Iceland, having persuaded the Icelandic authorities to approve its wood-chip sinking.
In fall 2023, Working Tide sank 19,000 tons of wooden chips into the ocean, promoting the world’s first marine Carbon Dioxide Elimination (mCDR) credit to Microsoft and Shopify as a part of a voluntary carbon market not regulated by authorities. In lower than a yr, the corporate shut down as criticism about its practices continued to swirl; Odlin cited a lack of American government support for the voluntary carbon market as the rationale for the closure.
Though $54 million represented a fraction of the $380 million total funding within the seaweed business, some suppose the carbon-sink aim was too slim, and missed all that seaweed might provide. “The long-term [carbon sink] potential attracted a swarm of speculators that took the business within the flawed course,” says Bren Smith, founding father of GreenWave, a forerunner within the ocean farming motion. GreenWave received roughly $6 million in 2021.
Smith believes that the dip in carbon-fueled funding will encourage the business to embrace seaweed’s many makes use of—as a very good meals for people and animals, as a game-changing various to chemical- and carbon-intensive industries like fertilizers or plastics, and for its confirmed ecosystem advantages. Additionally, seaweed doesn’t want arable terrestrial land, more likely to diminish as wildfires and excessive climate occasions like drought improve. “I don’t know if it’s 100 years or 5 years, however we’re gonna be rising big quantities of meals underwater,” he predicts.

The droop in non-public funding isn’t the one monetary problem for seaweed. Scant federal funding provides to the wrestle. In Europe, many ocean startups obtain authorities help, in accordance with Ronald Tardiff, Ocean Innovation Lead on the World Financial Discussion board, whereas within the U.S., most authorities funding goes to analysis establishments relatively than for-profit firms. (The Division of Power, an vital supply of analysis funding relationship again many years, contributed some $20 million to seaweed analysis within the Seventies by its MARINER program, and continues to help science; see “Seaweed Investments by Class” beneath.)
“The E.U. has spent . . . . a whole lot of thousands and thousands of euros on R & D associated to seaweed, in a method that the U.S. has not. And lots of startups have benefited from these E.U. initiatives,” says Tardiff, mentioning that Ocean Rainforest, a for-profit entity, has obtained intensive E.U. funding. In China and Korea, the place seaweed farming first developed into a bigger business, governments present kelp seed to farmers for free or at a sponsored price. The shortage of state help within the U.S., says Tardiff, additionally means the American seaweed market is extra tied to market fluctuations than its Asian and European rivals.
The paucity of each non-public and authorities funding makes it more durable for seaweed firms to deal with the excessive price of farming and processing. “The ocean is uniquely costly to function on,” says Tardiff, who additionally serves because the Lighthouse Lead of 1000 Ocean Startups, a world coalition of incubators, accelerators, competitions, matching platforms, and VCs which have pledged to again a minimum of 1,000 “transformative” startups by 2030.
Primary seaweed farming tools, like a ship, prices anyplace from $30,000 to $500,000; a single seaweed-line anchor—and a farm wants a number of—can price $1,000. Additionally, as a result of kelp is unusually perishable, it requires million-dollar investments in infrastructure tools, like specialised dehydrators and freezers, to render it shelf-stable. A lot of it’s custom-built for this new meals enterprise.
Retail Stoop Meets Inflation
Declining funding has hit kelp meals firms significantly arduous, since they’re additionally coping with shrinking grocery-store revenues, especially for consumer packaged goods (CPG)—which incorporates most seaweed meals. Additionally, excessive inflation charges imply a seaweed snack or seasoning gained’t do as effectively; when meals costs are up total, shoppers are much less more likely to spend on meals that aren’t acquainted.
Describing the present CPG market as “brutal,” Courtney Boyd, founding father of AKUA kelp burger firm, closed her operation this August. Boyd based her kelp firm in 2016, supported by GreenWave, and for some time it was thriving: She raised $4.5 million in funding from 2020 to 2024, in accordance with Phyconomy. Wanting again, Boyd regrets not having invested in farming, as an alternative shopping for kelp wholesale from middlemen. She finally started working instantly with farmers in 2023, however it was too little, too late.
“With an inflationary surroundings, if you’re a consumer-package firm and also you don’t have lots of oversight when it comes to what’s occurring with the provision chain, you’re in bother when occasions are difficult,” says Julia Paino of Desert Bloom Meals, a meals investing agency.
