The renewable glycerine-based marine biofuel developed by UK-based company Quadrise has recorded improved efficiency boosts and emission reduction figures in new tests.

Quadrise said tests on its emulsion fuel in a Cummins 4-stroke diesel engine at the Aquafuel Research test facility in the UK showed “much higher diesel engine efficiency can be achieved with bioMSAR without increasing NOx emissions”.

Engine efficiency benefits of 3% and reductions of Nitrogen Oxide (NOx) emissions of more than 20% on diesel fuel were reported in a first phase of testing in 2021.
