[Digestion] Fueling your car with biogas!

[Ken Calvert]

O.K. here it is!

If you scrub your biogas to the quality of natural gas, then you can  fill a CNG converted  car in your garage over night, with no problems of HP storage because the car provides the HP storage.  
I would go more and say that an enterprising person could  also use the CNG gas tank of their car as storage to run ones household in the evening too.  Bolt on CNG conversion kits are readily available from Europe. Especially from Italy.   You might have problems in  getting it approved without a operators certificate as well, but thats a bureacratic problem not a technical one.   ATB Ken C.
