Hybrid biogas plant producing electricity

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

Have you any time thought of “Just a switch in your house which when in ON condition can fetch you electricity, and in OFF condition can generate biogas”. Yes this is absolutely possible and our extreme hard 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.(as
in the microbial fuel cell).
2. Rectify this current by use of a special device designed by us and get the output as 0.25V.
3. This obtained voltage is again applied to the microbial culture in biogas plant. By this accumulation
of acetic acid takes place in the biogas fermenter.
4. The accumulated acid can be easily converted into H2 gas by the action of microbes from
environment , using acetic acid as a selective component.
5. Further on passing this gas through hydrogen cells large amount of electricity can be generated
as per our requirement.

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