Hybrid biogas plant producing electricity

Abstract

Energy is thc major cause behind the development of a nation. By thinking on it we have worked onthe biogas plant and modified it to generate electricity. This generated electric current is sufficientenough to power an entire house. Also our idea can be implemented in country with huge amount oforganic waste material.

Have you any time thought of "Just a switch in your house which when in ON condition can fetch youelectricity, and in OFF condition can generate biogas". Yes this is absolutely possible and our extremehard efforts have made us to achieve this successfully.

Our project is based on four absolutely different and innovative steps.1. Removal of electrons from bacterial cells by use of accurate potential difference electrodes.(asin the microbial fuel cell).2. Rectify this current by use of a special device designed by LIS and get the output as 0.25Y.3. This obtained voltage is again appl ied to the microbial culture in biogas plant. By this accumulationof acetic acid takes place in the biogas fermenter.4. The accumulated acid can be easily converted into H2 gas by the action of microbes fromenvironment, using acetic acid as a selective component.5. Further on passing this gas through hydrogen cells large amount of electricity can be generatedas per our requirement.

The entire process takes place in biogas plant fermenter and hydrogen gas can be generated onlywhen the 0.25V voltage is applied to the culture in the plant's frementer. In the absence of voltagethis plant produces 95 % methane and not 70% as per the primitive plant did (a solid experimentalproof for this). Thus pure methane as well as electricity can be generated by this plant by the switchover of a single switch. For implementation of this technique large funds are also not required andeven a simple farmer can adopt this technique. Moreover the existing biogas plants in the country canalso be modified by the introduction of certain metal electrodes in it. It can be concluded that thistechnique to certain extent can help in the development of rural areas in developing countries andmake their dream of "developed nation" achived.
