Bottling biogas in goshala
Founder of Sri Govind Goshala Prahlad Brahmachari has adopted the cryogenic super-cooling method to segregate methane present in biogas and has set up his compressor equipped plant under a tin shade of 400 square feet in the goshala.
“The aim has been to make the goshala self-reliant. For this purpose, I worked for two years to gather information from the internet as well as visited IIT-Delhi and four cylinders of 4 kg capacity each were filled in my bottling plant on June 10 which has aptly been named Kamdhenu,” Brahmachari says.
“By adopting this method, we manage to segregate 65% methane, 34% carbon oxide and 1% hydrogen sulphide present in the biogas,” he says, adding the carbon dioxide obtained in this manner is in the form of dry ice which can be used for refrigeration purposes.
Brahmachari says he has found that 1 kg methane costing him just Rs 5 (excluding the cost of cow dung) is enough for an old Maruti van to run 25 km or a three-wheeler 45 km.
He says he has already approached a company in New Delhi, Didvania Compressor Limited, which has assured him of providing a compressor worth Rs 1.5 lakh that could be installed in small goshalas.
Brahmachari says that according to the Uttar Pradesh Biogas Research Station, cowdung from one cow in a year could provide energy worth 225
