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.

Recent Highlights

Building momentum with technology validation, strategic partnerships, and new projects

Scaling with Existing Refinery Infrastructure

Alder, 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 by integrating ARC into existing refinery FCC units, with improved handling, storage stability, and strong product yields.

Project Avance Milestone for Advanced Biofuels

Project Avance demonstrated barrel-scale ARC production from commercial fast pyrolysis oils derived from forestry residues. The campaign focused on the final unit operation in Alder’s process, showing consistent performance across different commercial pyrolysis feedstocks and supporting a flexible pathway to refinery integration and scale-up.

Alder SAF100: 100% Biogenic Jet Fuel

Alder SAF100 demonstrated a 100% biogenic jet-fuel blend using hydrotreated Alder Renewable Crude (ARC) as the majority component with a smaller share of HEFA-SAF. Testing showed favorable energy density and low-temperature properties, highlighting the potential for ARC-derived hydrocarbons to support next-generation SAF production.
