• Kvasir Technologies raised €10 million ($11 million) to commercialize climate-neutral drop-in marine fuel.
• European Energy joined as a new investor and strategic partner through KVEEN Biofuels.
• The fuel can be used in existing vessels without engine or infrastructure changes.

Danish Startup Targets Shipping’s Fuel Gap

Danish biofuel startup Kvasir Technologies has raised €10 million in Series A funding to accelerate the commercialization of climate-neutral marine fuel.

The round brings European Energy into Kvasir’s investor base as a new strategic partner. Existing investors EIFO, Mærsk Growth and Footprint Fund also participated.

The capital will support the development and design of a new commercial production plant. It will also help Kvasir scale a drop-in fuel that can be used in existing vessels.

The investment arrives as shipping companies face rising pressure to decarbonize fleets without stranding assets. The sector carries global trade, but it remains one of the hardest industries to clean up.

“This investment round enables us to take the next crucial steps in developing and scaling our technology. At the same time, it underlines that there is still strong support for solutions that can deliver real climate impact in the maritime sector,” says Joachim Bachmann Nielsen, Ph.D. in Chemical Engineering and CEO of Kvasir Technologies.

Drop-In Fuel for Existing Fleets

Kvasir Technologies spun out of research at the Technical University of Denmark. Its patented process converts non-edible lignin-based residues from agriculture and forestry into refined biofuels for shipping.

The company says the fuel can replace fossil marine fuel without changes to ship engines or existing infrastructure. That point matters for a sector built around long-life vessels, port systems and capital-heavy supply chains.

For shipowners, a drop-in fuel could reduce transition risk. It may also help operators comply with tightening climate rules while avoiding large near-term retrofits.

European Energy and Kvasir are also forming KVEEN Biofuels. The joint company is working toward a commercial-scale plant using Kvasir’s technology.

“What will be decisive for Kvasir’s technology is that, through innovation and scaling, we achieve attractive price points for customers and thereby secure long-term offtake agreements before construction begins. We have some experience with that process and look forward to the collaboration,” says Knud Erik Andersen, CEO of European Energy.

Denmark as First Scale-Up Market

The funding will support scale-up work at Kvasir’s test facility in Fredericia. The site can produce up to 2 tonnes of biofuel per day.

At the same time, the company will begin development work on its first commercial plant in Aabenraa, in southern Jutland. The project is designed to prove the technology at industrial scale before wider deployment.

“With European Energy, we gain a partner with proven experience in developing and financing energy infrastructure at scale. This reduces the risk of our first commercial plant and accelerates our route to market,” says Ulrik Falkenberg Lending, CCO of Kvasir Technologies.

For investors and maritime executives, the Aabenraa plant will be an early test of commercial readiness. It will need to demonstrate fuel quality, feedstock reliability, production economics and bankable offtake demand.

That is where the European Energy partnership could prove important. Scaling fuel production requires more than technology. It also needs project development, infrastructure financing and long-term buyers.

Climate-Tech Capital Still Moving

The investment comes during a difficult period for many climate-tech startups. Higher interest rates, slower venture deployment and tougher diligence have made fundraising harder.

Kvasir’s round suggests capital remains available for companies with mature technology and clear routes to market. It also reflects continued demand for solutions that can cut emissions in sectors with limited near-term alternatives.

“Kvasir Technologies represents a technological solution with strong potential to reduce CO2 emissions in one of the hardest sectors to decarbonize. The combination of scalable technology, a biofuel that can be used in existing fleets and strong partnerships makes the case particularly attractive,” says Sara Sande.

For the C-suite, the strategic relevance is clear. Shipping decarbonization will not depend on one fuel pathway. Methanol, ammonia, electrification, efficiency gains and biofuels will all compete across routes and vessel classes.

Kvasir’s proposition is strongest where immediate compatibility matters. If the company can reach competitive price points and secure long-term offtake, its fuel could help bridge the gap between today’s fossil fleet and tomorrow’s low-carbon shipping system.

For Denmark, the deal also reinforces the country’s role in maritime decarbonization. For global markets, it offers another signal that hard-to-abate sectors are moving from pilot projects toward infrastructure-scale climate investment.
