Compressed biogas is the fuel of choice and necessity for India and the world. Biogas can be purified and compressed to meet the nation’s fuel requirements and thus throw a good opportunity for development and growth of biogas plants in the country. India, especially with her huge cattle population and limited amount of land will benefit the most with the use of compressed biogas. We have an inexhaustible source of biological waste, by utilising that waste for power generation we can avoid dumping in the landfills, thus save land for cultivation.

While technology to compress biogas has already been devised, it has been used only in rural household for cooking purposes only. It was utilized for the traditional purpose of using it as manure. No effort was made to use this waste for the purpose of production of energy to run power plants, vehicles etc. Whereas compressed biogas has the potential to match CNG standards by use of advanced technologies. Biogas has 60% of methane content and 40% of carbon dioxide, the purified form obtained after processing matches the methane content of CNG. The CBG produced can be used in the same cylinders that store CNG; it will be equivalent to the efficiency of CNG, and can be used to run power plants and vehicles.

By an approximate formula, 100 cows will give/day 1000/Kg of cow dung, this in a bio digester will yield about 40 M3 of Gobar gas. After removing impurities such as CO2, Sulphur, Moisture etc will yield about 20M3 or 17Kg of pure methane gas. Gober gas is purified of all impurities and moisture. Pure Methane gas is than Compressed. This Compressed Bio – Gas thus obtained is capable of running Power plants & Vehicles.

This sort of Pilot Project can be designed as per the customer requirement for,
  • Bottling Biogas
  • Generating power using non-conventional energy
  • Driving conventional vehicles using non-conventional energy
So, by converting this decaying organic mass to energy, we will not only be saving money, but also our environment. Since CBG is produced from biologically produced material, it is part of recirculation and does not contribute to the carbon dioxide content in the atmosphere.

CBG helps in reducing Carbon Emissions
As a transport fuel it reduces
  • CO emissions by 90-97% & CO2 emission by 25%
  • NOX emissions by 35 – 60%
  • Hydrocarbon emissions by 50 -75%
  • Emits little or no particulate matter
