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.

Coprocessing ARC with Fluid Catalytic Cracking

At Alder Renewables, we’re committed to creating practical, scalable solutions that help decarbonize transportation fuels. A major step forward in that journey is the successful completion of a pilot FCC co-processing campaign with the U.S. Department of Energy’s National Renewable Energy Laboratory (NREL).

Demonstrating Refinery Compatibility

The pilot testing was carried out using NREL’s Davison Riser Reactor, a facility designed to generate commercially relevant fluidized bed and regeneration data. Industry partners supplied the vacuum gas oil (VGO) and FCC catalyst used in the trials, ensuring the conditions closely matched those in commercial refinery operations.

In the campaign, Alder Renewable Crude (ARC)—derived from forestry residues—was co-processed alongside conventional VGO. The goal was to evaluate yields, product quality, and refinery operability when ARC is blended into existing FCC streams.

Strong Results with High Fuel Yields

The results were encouraging. ARC was successfully converted into high yields of liquid transportation fuels, with the biogenic portion of those fuels confirmed through radiocarbon (14C) analysis by Beta Analytics. Distillation and 14C testing further demonstrated that the product distribution was comparable to fuels produced from VGO alone.

Importantly, the analysis also showed significantly lower levels of trace oxygenates in both light gases and liquid products when compared to other bio-oils containing pyrolytic sugars. This finding underscores ARC’s potential as a cleaner, refinery-ready feedstock that integrates with existing infrastructure.

Looking Ahead: Scaling to Market

These results highlight the promise of ARC as a drop-in solution for refineries seeking to lower their carbon intensity without major changes to operations. The next phase of work will focus on FCC refinery trials with commercial partners, paving the way for ARC’s entry into the fuel supply chain.

“This campaign with NREL marks a key milestone for Alder. Demonstrating ARC’s compatibility with FCC units for coprocessing—one of the most widely used processes in refining—shows how our technology can deliver meaningful carbon reductions at scale with minimal capital investment,” said Derek Vardon, CEO of Alder Renewables. “We’re excited to take the next step with industry partners to prove this at commercial scale and bring low-carbon fuels closer to market.”

With each milestone, Alder is helping to build a future where renewable feedstocks power transportation more sustainably—without compromising on performance, scale, or cost.
