Kvasir Technologies and Crossbridge Energy Join Forces to Develop Bio-oil for Green Marine Fuels

12.11.2026 - Cleantech company Kvasir Technologies and refinery operator Crossbridge Energy have signed a Memorandum of Understanding (MoU) to assess the co-processing of Kvasir's bio-oil at Crossbridge Energy's refinery in Fredericia. The collaboration aims to support the development of green fuels for the shipping industry.

Shipping accounts for approximately 3 percent of global CO₂ emissions. With FuelEU Maritime and the EU Emissions Trading System now applying to the sector, pressure to reduce emissions is increasing. At the same time, much of the global fleet will continue to rely on liquid fuels for years to come. Green fuels that can be used in existing engines and infrastructure will therefore be an important part of the transition. Kvasir Technologies and Crossbridge Energy will work together to help address this need.

Under the agreement, the companies will assess whether bio-oil produced using Kvasir's proprietary technology can be co-processed at Crossbridge Energy's refinery in Fredericia. Kvasir's solvothermal liquefaction process converts forestry and agricultural residues into bio-oil. The bio-oil will be produced at Kvasir's Demo test facility, which is located on Crossbridge Energy's site close to the refinery. This proximity brings testing, production and refining expertise together in Fredericia.

By introducing bio-oil into an existing refinery process, the partners aim to demonstrate how renewable feedstocks can be integrated into the fuel supply without the need to build an entirely new production and distribution chain. As Crossbridge Energy supplies more than one-third of Denmark's fuel products, the refinery provides a strong platform for testing the solution and exploring its potential at scale.

In parallel with the technical work, the partners will explore the basis for a potential commercial collaboration, including how the fuel's renewable content can be traced and certified. Both companies view the MoU as a first step towards broader cooperation on green marine fuels.

Laboratory testing is expected to begin in 2026, with the first full-scale refinery trial planned for 2027.

"This is an important step for Kvasir. We have developed a technology that turns forestry and agricultural residues into bio-oil, and in Crossbridge, we have found a partner with the infrastructure and expertise needed to turn that bio-oil into a fuel the shipping industry can use," said Ulrik Falkenberg Lending, CCO at Kvasir Technologies. "Co-processing at an existing refinery lets us bring green molecules into today's fuel infrastructure much faster than if everything had to be built from scratch."

The initiative creates a direct pathway from local innovation to lower-emission maritime applications.

"At Crossbridge Energy, we are working to apply our refining know-how, existing resource streams and infrastructure to create green value through the partnerships we enter into. Our collaboration with Kvasir is a strong example of that approach: it brings together Danish technology and our industrial capabilities to explore how bio-oil can become part of our processes in Fredericia," says Henrik Rømer, Business Director and continues: "Partnerships like this can help turn shared ambitions into practical solutions for sectors such as shipping, where the transition depends on fuels that work with existing infrastructure."
