Cleaner alternatives to heavy fuel oil

There is concern in the marine sector that future demand for biofuels will surpass supply availability, in part due to feedstock competition from the road and aviation sectors. Quadrise’s Oil-in-Water (OIW) emulsion fuel technology provides an innovative solution to this problem, allowing ship owners to unlock cheaper, low-carbon biofuel streams that were previously inaccessible for energy sector use. What are oil-in-water emulsion fuels? As the name suggests, an OIW emulsion fuel combines two notoriously immiscible phases, oil and water, to create a stable fuel blend using small quantities of surfactants. Quadrise’s proven bioMSAR™ emulsion fuel combines 50% of an oil component (heavy fuel oil, HFO, or heavy residue which can be high or low sulphur) with 40% waste glycerine and 10% water and surfactant mixture. Glycerine is a non-toxic, low-carbon by-product from the manufacture of biodiesel that is traditionally immiscible with current marine fuels. With bioMSAR™ technology, glycerine blending is now a viable and immediate solution to decarbonise the marine...
