Through a Joint Development Agreement with Quadrise, Alder is demonstrating Alder Pyrolytic Sugars (APS) as a renewable feedstock for advanced marine fuels. By combining our biomass conversion technology with Quadrise’s bioMSAR™ platform, the collaboration aims to deliver a scalable and cost-effective pathway to decarbonize the shipping industry—one of the hardest sectors to abate.
The global shipping industry is under increasing pressure to decarbonize, and practical, scalable solutions are urgently needed. At Alder Renewables, we believe our technology can play a vital role in this transition. That’s why we are proud to announce a new Joint Development Agreement (JDA) with Quadrise to accelerate progress toward cleaner marine fuels.
Our Technology, Their Platform
At the heart of this collaboration is our Alder Pyrolysis Sugars (APS), a renewable intermediate produced from sustainable biomass using our proprietary pyrolysis oil upgrading process. Through the JDA, APS will be evaluated as a feedstock for Quadrise’s bioMSAR™ and bioMSAR Zero™ fuels—advanced emulsion fuels designed as cleaner, lower-cost alternatives to heavy fuel oil in shipping.
By combining our biomass conversion expertise with Quadrise’s fuel technology, we aim to create a pathway to truly scalable, cost-effective low-carbon marine fuels.
A Clear Path to Demonstration
The agreement establishes a staged development plan:
Why It Matters
Looking Ahead
This JDA marks an important step forward in demonstrating the role Alder’s technology can play in marine decarbonization. Together with Quadrise, we are working to unlock a new, scalable route to sustainable shipping fuels—helping the industry move closer to its net-zero ambitions.
Building momentum with technology validation, strategic partnerships, and new projects

We are proud to announce that Stephen Schueler, former Chief Commercial Officer at A.P. Moller - Maersk, has joined the company as a Strategic Advisor and Shareholder. Stephen currently serves as Managing Director, Green Transition, Investment Advisory Board at European Maritime Finance, focusing on sustainable shipping investment strategies. He is on multiple leading global boards as a shareholder and trusted advisor.

Alder Renewables, BASF, National Laboratory of the Rockies, and North Atlantic Refining co-authored a new Hydrocarbon Processing article on coprocessing Alder Renewable Crude in fluid catalytic crackers. The work highlights a practical pathway to produce renewable fuels with existing refinery assets, improved handling, better storage stability, strong yields, and biogenic carbon integration for today’s energy infrastructure at commercial scale globally.

Project Avance demonstrates a scalable, cost‑effective path to advanced biofuels by converting forestry residues into refinery‑ready ARC. The pilot campaign met performance targets, showing scientific and operational progress. By leveraging existing pyrolysis and refinery infrastructure, the approach reduces costs, enhances energy security, and proves abundant biomass can deliver viable low‑carbon fuels.
