Enabling Low-Carbon Marine Fuels with Quadrise

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:

• Laboratory Evaluation: APS is being tested with Quadrise’s emulsion platform at their UK research facility.

• Engine Bench Testing: Small-scale diesel engine trials will confirm combustion performance.

• Marine Demonstration: Pending success, APS-based bioMSAR™ fuels will advance to full-scale marine engine trials within the next year.

Why It Matters

• Decarbonizing Shipping: Marine transport is one of the hardest sectors to abate. Our technology offers a renewable feedstock that can be integrated into existing fuel infrastructure.

• Cost and Scale Potential: APS represents a pathway to abundant, affordable, and sustainable marine fuels.

• Technology Synergy: Pairing Alder’s front-end biomass conversion with Quadrise’s fuel innovation creates an end-to-end solution designed for real-world impact.

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.
