From NOK 36 to One Øre: Alginor's EIC Accelerator Kelp Biorefinery

Alginor set out to build the first kelp refinery that uses all of the seaweed it harvests and no formaldehyde. The Norwegian company from the Haugesund area won blended finance in the EIC Accelerator pilot's Green Deal cut-off of 19 May 2020 for DACOTA, a project to design and then build a demonstration biorefinery and a harvesting vessel for the cold-water kelp Laminaria hyperborea. The EU grant was €2,494,517 towards a total cost of €3,563,596.25, according to CORDIS, and the company said the award also offered up to €15 million of equity, the maximum the scheme allowed, in its launch announcement.

Six years later the harvesting vessel exists and sails. The refinery does not run. In May 2026 Alginor froze the unfinished plant, known internally as F3, and temporarily laid off staff, according to its shareholder letter of 28 May 2026. In August its three largest shareholders converted their loans and injected new cash at NOK 0.01 per share, against NOK 36 per share paid in June 2024. Borregaard, the listed Norwegian biorefiner that had been its largest shareholder, wrote its whole investment down to nil, according to Borregaard's second-quarter 2026 report.

Where Alginor Stands Now

Alginor is operating, on a much smaller plan. The Norwegian register lists Alginor ASA as an active public limited company, not bankrupt and not in liquidation, with share capital of NOK 344,380,040.76 split into 34,438,004,076 shares registered on 16 September 2026, according to the Brønnøysund Register Centre. That share count is the result of the rescue approved at an extraordinary general meeting on 31 August 2026: the nominal value of the existing 47,152,976 shares was cut from NOK 1 to NOK 0.01, and 4.7 billion new shares were issued for NOK 47 million in cash and 29,690,851,100 for the conversion of about NOK 296.9 million of shareholder loans, according to the meeting minutes and the company's information letter of 2 October 2026. A repair offering of up to 6,335,100,000 shares at the same price for the other shareholders closes today, 15 October 2026; its result is not yet public.

The company says the new money funds work at its F2 pilot facility and laboratory, continued harvesting, a drying concept and "planning a restart of the F3 facility", but not the restart itself: "Further capital will be required before the company can be expected to generate revenue on a scale." Peer Lea, a former Boston Consulting Group partner who joined as finance chief in April, became chief executive on 1 September 2026. He is the fifth chief executive, counting interim and acting ones, since Kjetil Rein stepped down in early 2025, according to company announcements from April 2025 and May 2026.

The Technology: All of the Kelp, None of the Formaldehyde

Alginate, a thickener and gelling agent extracted from brown seaweed, goes into food, wound dressings and medicines. Alginor's case rests on how it is made. In its EU reports the company says today's alginate industry uses formaldehyde and uses only about 15% of the kelp it harvests, releasing the remaining biomass, contaminated with formaldehyde, back into the sea, and that Norwegian discharge permits for formaldehyde therefore cap production, according to the final report of its earlier EU project. These are the company's statements, reproduced by CORDIS; they were not independently verified for this article.

Alginor's alternative has two parts. Hypomar is its harvesting method, which it says "interferes minimally with the seabed and surrounding marine life". AORTA is the processing route, which separates stem and leaf and extracts the raw material without formaldehyde, with the aim of using up to 100% of the biomass for a portfolio of 12 ingredients, among them alginate, fucoidan, native cellulose and polyphenols, for pharmaceutical, nutraceutical and other markets, according to CORDIS. The regional environmental authority describes the planned plant more plainly: separation of stem and leaf, grinding, alkaline extraction of alginate, dewatering, drying and packing, with intake of 33,500 tonnes of kelp a year and capacity for 2 tonnes of sodium alginate a day, according to the permit decision of 21 May 2026 by the County Governor of Rogaland.

That permit is temporary, for 18 months. The authority first notified Alginor in January 2025 that it intended to refuse the original application under the Water Regulation, and granted the narrower permit so that the company could run test production and investigate its emissions, noting that "the new technology to be used has not been tested". It has been tested at pilot scale: the company reports larger ingredient runs at external piloting facilities and smaller production at its own sites in the DACOTA report.

What DACOTA Promised, and What CORDIS Shows

The European Commission's list of companies selected in the 19 May 2020 Green Deal cut-off names "Alginor" of Haugesund as the only company behind DACOTA, with blended finance. The same document also lists Alginor ASA for AORTA 2, an earlier EIC SME Instrument Phase 2 project that ran from September 2018 to December 2020 with an EU contribution of €1,939,262.50, according to CORDIS; a €50,000 Phase 1 feasibility study, AORTA, came first, in 2017. AORTA 2 verified the process at pilot scale. DACOTA was the step to industry.

DACOTA had two stages. The grant was to pay for designs of a demonstration biorefinery and a harvesting vessel, each able to handle 10,000 tonnes of wet kelp a year. The equity stage was to build them: the CORDIS objective puts that stage's capital cost at €31.06 million, of which €15 million from the EIC, €5.57 million from private placements and €10.49 million from loans, ending in "market deployment" of the 12-product portfolio. The grant ran from 1 November 2020 to 30 June 2022, on schedule. Its final report describes process flow diagrams, requirement specifications, 2D and 3D drawings of the demonstrator and a financial model, and says the grant would leave Alginor "ready to make an investment decision".

5. Market deployment of the 12-product portfolioNot achievedNo revenue in 2025; NOK 109,846 in 2024.

The vessel is the clearest result. Hypomar Ocean 1 was delivered by Fitjar Mekaniske Verksted on 2 May 2024, according to Alginor, and the trade newsletter Phyconomy reported in July 2025 that the harvester "was delivered on budget" and that the pilot plant was operating. The plant itself changed shape. During DACOTA the planned scale rose from 10,000 to 33,500 tonnes, and the company chose to build a food-grade facility first, targeted for 2024, with a pharmaceutical facility to follow, according to its 2022 annual report. Its 2025 annual report says cGMP approval for that facility "is not expected in the near-term" and a separate pharmaceutical plant, F4, is "far out in time". By its own description, the company is a long way from the API demonstrator the EU grant was meant to prepare.

The Money: More Than NOK 1 Billion, Then a Reset

The EIC award opened the door to private capital. On 23 July 2021 Alginor signed an investment agreement worth up to NOK 500 million with Hatteland, the EIC Fund and Borregaard, tied to the DACOTA award, according to its 2021 annual report. Borregaard announced its own entry on 22 July 2021, an investment of about NOK 144 million for 24.99% with an option to reach 35%, in a company release. The EIC Fund and Borregaard each held about 25% of the shares at the end of 2022, according to Alginor's 2022 annual report. How many euros the EIC Fund itself paid in is not stated in any source opened for this article, so whether the full €15 million was invested could not be verified. Alginor appears on the EIC Fund's list of invested companies.

The money kept coming as the plans grew. Alginor raised about NOK 400 million in a private placement at NOK 36 per share in June 2024, with pre-commitments from Borregaard, the European Innovation Council and Hatteland, according to the company. In February 2025 it disclosed that completing F3 would cost a further NOK 500 to 550 million, taking total capital spending on F3 and the F2 pilot plant to NOK 820 to 870 million, and it raised NOK 150 million at NOK 10 per share, according to its April 2025 announcement. Phyconomy called it a down round and put the total invested in the company at "just over NOK 1 billion". In October 2025 the three largest shareholders guaranteed a NOK 200 million convertible loan, and Haugesund Sparebank committed a NOK 230 million secured loan, according to a Borregaard release.

The 2025 accounts then reset the value of what had been built. The group reported no revenue, impairments of NOK 774.2 million and a net loss of NOK 870.7 million, and group equity fell from NOK 820.5 million to NOK 113.5 million, according to the annual report and the accounts filed with the Register of Company Accounts. The board explained the write-downs with rising F3 costs, higher costs for harvesting and drying, slow commercialisation and a higher probability of liquidation "as major shareholders were reluctant to provide further capital".

Borregaard drew the conclusion in public. It recorded an impairment of NOK 337 million on its shares in Alginor and its convertible loans in the second quarter of 2026, citing "challenges relating to raw material supply, delays in product development and commercialisation, and further cost overruns", and said it considered it "unlikely that the current value of Alginor exceeds the company's bank debt and other prioritised obligations", in its quarterly report. It held 42% at the end of June 2026 and expects to hold 10% after the restructuring; Must Invest is to hold 10% and Hatteland between 64% and 79%, according to Alginor's July letter. The EIC Fund held 5,458,031 shares, or 11.6%, at the end of 2025 through a BNP Paribas nominee account, according to the 2025 annual report. Measured against the 34.4 billion shares now registered, that holding is below 0.02% unless the fund subscribed in the restructuring; whether it did is not public.

Staff, Harvest and the Raw Material Problem

The team grew every year after the award, from 33 full-time staff in 2021 to 62 at the end of 2025, according to the 2025 annual report. The same report says that in 2026 the company cut seven jobs and temporarily laid off 27 employees, about 26 full-time equivalents, when it paused F3. The Brønnøysund register lists 13 employees for Alginor ASA and 23 for Alginor Biorefinery AS in September and October 2026.

Raw material, the advantage Alginor stressed in every EU report, turned out to be a weak point. The May 2026 shareholder letter names "challenges with raw material supply and harvesting" as the first reason for the freeze, and the permit decision records that Alginor has switched the plant from fresh to dried kelp as its raw material, with fresh kelp used only for a limited number of start-up batches in summer 2026. Finding "a viable drying location" is now one of the conditions the company sets for seeking money to finish F3. Alginor also leads PROTEUS, a €14.4 million project with a €9.6 million grant from the Circular Bio-based Europe Joint Undertaking to build an integrated seaweed biorefinery at Avaldsnes, according to its 2024 announcement; the 2025 annual report says the company is "behind schedule on PROTEUS" and that its scope may have to be scaled down.

Why Europe Should Care

The EU wants more of its algae produced at home. In November 2022 the Commission adopted "Towards a strong and sustainable EU algae sector", with 23 actions to scale up "regenerative algae cultivation and production" and develop markets for food and non-food uses; the EU is "one of the biggest importers of seaweed products globally", and demand is expected to reach €9 billion a year by 2030, as The Fish Site reported at the time. A wild-kelp refinery in Norway that avoids formaldehyde and uses the whole plant fits that policy closely, which is why the EIC funded it in its Green Deal round and why the EU later backed PROTEUS as well.
