Aquafuel has developed new technology for the combustion of crude glycerine (glycerol) in standard diesel-engined Combined Heat and Power (CHP) generators. Developed in conjuction with leading biofuel supplier Greenergy, it further improves the sustainability of biodiesel production and is commercially available today.
Aquafuel’s technology allows biodiesel producers to generate their own electrical power, and use the waste heat to provide process steam. Any excess electricity can be sold to the local grid, or used to run electric boilers for more process steam. The result brings biodiesel production close to energy self-sufficiency and makes drastic cuts in fossil fuel usage.
Glycerine is a by-product of biodiesel production. For every 9 gallons of biodiesel, 1 gallon of crude glycerine is produced. Glycerine’s density and high oxygen content offer the potential of exceptionally clean combustion, with much lower emissions than burning diesel fuel. Aquafuel’s technology has turned that potential into practical reality.
The technology opens up the potential for any liquid fuels, from ethanol to gasoline, to be burnt at diesel efficiencies. The use of conventional, not bespoke, equipment means capital costs are comparable with conventional diesel CHP.
