Topsoe and Steeper Energy (Steeper) have signed a global licensing agreement for Steeper’s Hydrofaction™ technology, enabling Topsoe to offer a complete waste-to-fuel solution and at the same time a one-stop solution for refineries, project developers, and industries having access to excess waste biomass. The end-products include Sustainable Aviation Fuel (SAF), marine biofuel, and renewable diesel from waste biomass.

Peter Vang Christensen, Senior Vice President, Clean Fuels & Chemicals – Technology, Topsoe, said:
“We are excited to work with Steeper and to combine our technological capabilities. This will make it easier for refineries and project developers to access the technology they need for advanced biofuels. It will also allow them to access new renewable feedstocks while supporting decarbonization of the transportation sector, not least aviation and shipping.”

Bevan May, President, Steeper Energy, said:
“Steeper recognizes Topsoe as a world leader in developing and implementing renewable refining technologies. Steeper’s Hydrofaction™ process, when combined with Topsoe’s technology, completes the pathway from biomass waste to drop-in liquid fuels and is compatible with existing refining infrastructure. This reduces capital requirements and allows for the accelerated deployment of these solutions. We are excited to combine our efforts with Topsoe and bring our joint solution to the renewable liquid fuels market.”

Steeper’s Hydrofaction™ has been validated through various stages of continuous pilot and demonstration-scale plant operations over the past 10 years.

With this agreement, the parties are working towards the first commercial scale deployment of Hydrofaction™ technology.

What is Hydrothermal liquefaction
Hydrothermal liquefaction (HTL) applies supercritical water as a reaction medium for the conversion of biomass directly into a high-energy density renewable biocrude oil. Steeper’s unique process mimics and accelerates nature by subjecting wet biomass to heat and high pressure. The process conditions are carefully chosen to promote reaction pathways that favor high yields of high-quality renewable oil. With Steeper’s Hydrofaction technology it is possible to convert up to 85% of incoming biomass on an energy basis, making it one of the most effective conversion technologies available.
