The Technology Strategy Board GLEAMS project is currently investigating technology by which marine vessels will be able to surpass the very highest regulatory standards required for sulphur and nitrous oxide emissions, as well as slashing their carbon emissions and potentially reducing fuel costs. One solution may be the use of glycerol, (commonly glycerine), as a fuel for marine diesel engines. There is a global oversupply of glycerol, a by-product of the expanding biofuel industry.
