Urine-tricity++: Electricity from Urine

‘Urine-tricity’: Electricity from urine.

Background

Worldwide there are over 2.5 billion people without access to safe sanitation. In attempt to address this need The Bill and Melinda Gates Foundation are funding research on the topic: ‘Create the Next Generation of Sanitation Technologies’. As part of the Grand Challenges Exploration Scheme (Round 7) the Intelligent Bio Energy Group were awarded a Phase-I grant for the project 'Urine-tricity: electricity from urine'.

Project Aim

Urine-tricity successfully demonstrated the charging of a commercially available mobile phone, using Microbial Fuel Cells (MFCs) fed with real neat urine. Urine-tricity++ follows on as Phase II of the project, with the aim to develop MFCs into a mature sustainable energy technology with a direct application in everyday life that could change the way people perceive waste and energy.

Project GoalUrinal - MFC demonstrator

The proposed work is all about electricity generation, whilst cleaning the urine ‘fuel’ and producing clean water in addition to fertilizer, and is focusing on small-scale MFC units, which have been shown to be more efficient and energy-dense. The continuous flow nature of the MFC technology facilitates continuous growth of the constituent biofilm organisms, which clean the input, and can be subsequently used as fertilizer. In essence, the more powerful the MFC is, the greater are the rates of urine utilization.
