Quadrise publishes final results from bioMSAR fuel testing

In the UK, Quadrise Plc confirmed the finalization of results from bioMSAR fuel testing completed in November 2023 further to the Company’s announcement of November 27, 2023.

The ultimate objective of the Company’s bioMSAR program is to supply the marine and industrial fuel sectors with sustainable biofuels that are lower in cost, more efficient, safer yet simple to use, and which generate the fewest harmful emissions.

The bioMSAR Tests were conducted using the Company’s 40kW Cummins diesel engine installed at Aquafuel Research Limited (“Aquafuel”).

Key highlights of bioMSAR™ Tests

·      bioMSAR™ blends containing Vertoro’s Crude Sugar Oil (“CSO™”) reduced carbon dioxide (“CO2”) emissions by over 30% when considering increased engine efficiency of up to 7%, and significantly reduced emissions of Nitrogen Oxides (‘NOx’) and Carbon Monoxide (“CO”) when compared with diesel.

·      New bioMSAR formulations incorporating biofuels containing waste-based methyl esters were shown to reduce CO2 emissions by over 45%, increase engine efficiency by up to 7%, and reduce NOx and CO emissions significantly when compared with diesel, providing a new potential pathway to bioMSAR™ Zero.

·      bioMSAR™ with Crude Sugar Oils and other biomass-derived sugars

Quadrise and biorefinery specialists, Vertoro BV (“Vertoro”), have been collaborating to develop a cost-effective supplement or alternative to glycerine in bioMSAR fuel under the Joint Development Agreement (“JDA”) announced by Quadrise on 21 September 2022.

The bioMSAR™ Tests concluded in November were completed on blends of bioMSAR containing up to 40% of Vertoro’s CSO™ as a replacement for renewable glycerine. When compared with conventional diesel fuel, the CSO™ bioMSAR™ demonstrated:

·      Reductions of up to 25% in carbon dioxide (“CO2”) emissions before engine efficiency savings are considered.

·      Additional engine efficiency improvements of 6-7% resulting in reduced fuel use, taking total CO2 reductions to over 30%, in line with previous bioMSAR™ testing results.

·      Reductions in NOx of around 30%, comparable with 20-45% seen during previous testing with bioMSAR™ on the same engine.  Furthermore, a reduction in CO emissions of over 50% was measured, with negligible visible smoke.

·      Based on these results, testing of the 40% CSO bioMSAR and 40% glycerine-based bioMSAR on a larger medium-speed Wartsila engine at VTT is scheduled in H1 2024. This additional testing will be performed in parallel with testing of CSO™ in bioMSAR™ at levels above 40% at the Quadrise Research Facility (“QRF”) and at Aquafuel.

In addition to the CSO™ development programme described above, work is progressing under the JDA with BTG Bioliquids BV (“BTL”) on pyrolysis sugars derived from biomass, and with other prospective partners who can supply C5/C6 sugars at commercial scale.
