Here is all about production of electricity and hydrogen gas from urine. This slide is best for students presenting and belongs to new evolution.

2. Synopsis
• By definition it is that system which converts urine that we have been
considering a waste product into electricity.
• This electricity can be used at the instant or can be stored, which can be
further utilized for light load applications at various public establishments.
• This system can be taken into use at public places like malls, schools,
hospitals etc.
• Same experiment can be carried out with cattle’s urine as it is observed that
it contains more urea which is require in electrolysis process to obtain
hydrogen .

4. Major working system
Urine is basically an aqueous substance that contains 95% of water and remaining 5%
of which contains other chemicals and 2% of urea within it.
Anode reaction: (NH2)2CO + 6OH- →
N2 + 5H2O + CO2 + 6e-
Cathode reaction: 6H2O + 6e- → 3H2 +
6OH-
Overall reaction: (NH2)2CO + 5H2O →
N2 + 3H2 + CO2
Phase I

5. Phase 2
At anode:
H2 = H+ + e-
At cathode:
o2+ e-+ H+ = H20
This is the main field of electric generation. In this process, around three
times of power used for disintegration of Urea is generated. The output or
the amount of electricity depends upon the size of the plant.

6. Sample Model

7. Power Calculation
• Urine contains around 95% of water
• remaining 5% of other chemicals.
• Among that 2% is the Urea
So, 1 liters of Urine contains 20 ml of urea
And, 1 mole of urea contains 4 mole of hydrogen.

11. Some Successful Story
The urinal is the result of a partnership between researchers at the University of the West of England in
Bristol and Oxfam. It is located near the students' union at the university's Frenchay campus and
researchers will be hoping for brisk business at closing time.

Students and staff are being asked to use the urinal to donate pee. The research team is led by Professor
Ioannis Ieropoulos, "Work by the Bristol BioEnergy Centre hit the headlines in 2013.

12. A research team from BBiC travelled to the Sesame Girls School in the small village of Kisoro in Uganda
in July to install Pee Power and a lighting system for a toilet block.
It was successfully done in 2011.

13. UK based Cypriot-developed ‘pee power’ toilets gaining ground after
Glastonbury success which could power a mobile and light a house at
Glastonbury Festival.

14. It was the year 2012 in Maker Faire Africa in Lagos had an successful demonstration of a urine powered
generator, created by four girls.
The girls namely Duro-Aina Adebola, Akindele Abiola, Faleke Oluwatoyin and Bello Eniola made a
ground breaking product that insured generation of six hours of electricity with the use of one liters of
electricity.
