[Digestion] Compressing of biogas

[Voegeli, Yvonne]

Dear Harold

In the developing countries context, I don't know of any biogas plant that is using the gas as a fuel for vehicles. However, the Indian Institute of Technology IIT in Delhi is doing research on biogas bottling and they run a demonstration vehicle on biogas. I will send you a paper and a ppt-presentation to your private email address. There is information on the capacity of the biogas plant, cost estimates etc. A colleague who works at IIT told me that one problem with the biogas fuel is that the bottle is very heavy and takes a lot of space in the car, but still you don't get very far with just one bottle.  And of course there are no other filling stations... The same is of course true for Tanzania - I don't think that at the moment this would be feasible.

Best regards,
Yvonne

Subject: [Digestion] Compressing of biogas

hello
Got a question from the owner of a small biogass plant in Tanzania.
He is expanding a small existing biogas plant to be able to digest waste from 200 households and manure from 100 cows.
He is interested in using the biogas for fueling vehicles. In our part of the world we think it will be necessary with cleaning, uppgrading of the gas and compressing.
Do any of you have experience/ideas about whether this is feasible for such a small plant?
1)What is necessary to use the biogas for fueling vehicles and 2) what are the technical and economical consequences?
Thank you
