Quadrise plc Quadrise plc develops and commercializes emulsion fuel technologies that produce MSAR and bioMSAR fuels as lower-cost, lower-emission substitutes for heavy fuel oil and conventional biofuels in marine, power generation, industrial, and steam applications; these oil-in-water emulsions incorporate heavy residual oils, water, and additives, with bioMSAR variants utilizing waste-derived biofuels for enhanced sustainability. The company targets shipping operators, utilities, and industrial consumers globally, with operations spanning Europe, the Americas, and emerging markets including marine trials in Antwerp, power plant testing in Panama, and development projects in Utah. Founded in 2004 and headquartered in London, Quadrise changed its name from Quadrise Fuels International plc in March 2023 to reflect its broader energy technology focus. Recent developments include a successful oversubscribed fundraise in January 2025 to bolster commercialization efforts; execution of a binding trial agreement with MSC Shipmanagement and Cargill for MSAR and bioMSAR testing on the MSC Leandra vessel, with site preparations completed at Antwerp's MAC² facility; successful proof-of-concept trials at Sparkle Power's El Giral plant in Panama in July 2025 validating fuels on Everllence engines; an addendum to the Site License and Supply Agreement with Valkor in Utah for licensing fees and equipment deployment; and new joint development agreements in 2025 with Alder Energy, Licella Holdings, BTG Bioliquids, and Vertoro to integrate renewable feedstocks, alongside lifecycle analysis for regulatory compliance.
