A group of scientists from Heriot-Watt University in Edinburgh, UK have developed a prototype which can turn urine into energy, called the Carbamide Power System. The prototype has been developed by Dr Shanwen Tao and his research partner Dr Rong Lan, who’ve received a £130,000 EPSRC grant to develop it.
Advantage:
No expensive Hydrogen storage, onsite Hy production from Water Oxygen and Urea.
Urea price $0.40/litre $1.50/gln
Explainer: Urea or Carbamide
Urea, or carbamide, a mass manufactured fertilizer,
which can also be found in human or animal urine.
Urine contains roughly 2 per cent urea, and each urea molecule contains four hydrogen atoms, which, crucially, are less tightly bound to the molecule than the hydrogen in water.
No heat involved
electrochemical process that does not require combustion,
with heat as the by-product.
Blue Diesel (Urea mix) already in Trucks Europe
Urea UE law to lower the toxic nitrogen oxides produced when diesel combusts, trade name AdBlue. Also available for Blue diesel Daimler
Urea power 2.700 km - 1.700 mls /person/ year
One adult human produces enough urine each year to drive a car 2700 kilometers on energy from the urea it contains.
