Biofuel is a better choice for excess biogas at Farms

Tweet

The auto fuel cost is reaching new highs just like our hot weather sets new records.
At the same time natural gas prices are subject to surplus supply and keeping it low.
The sustainable green solution for the dairy farms is to build the digesters and process their manure and some imported food processing waste.This concept will generate more biogas and result in larger power generation potential. Once the amount of power produced equals the usage at farm, they are energy independent. It is not economically attractive to make excess power.This scenario offers perfect opportunity to compress the excess gas and convert it to bio-CNG for vehicle fuel which offers better returns. Unfortunately this option requires large capital expense, so many smaller farms need to combine their excess gas for centralized cleaning and biofuel production. County Governments can play a key role in this area by providing low cost long term loans to help in construction. All of their public works vehicle would benefit with low cost fuel after conversion to CNG fuel.
DOE can and should help implement this option in all counties that have large number of dairy farms.
This is the time for our Federal and State Governments to take the lead and help utilize this great opportunity for dairy waste to be converted to biofuel.
