Dual Fuel

Using two types of fuels (e.g., electricity and natural gas) to perform work.

In the case of combined electric and natural gas pumping facilities, several types of configurations are possible:

    • One pump connected to a gas engine and an electric motor using a combination drive;


    • A natural gas engine and a electric motor connected to individual pumps but drawing from the same sump or water source; or


    • One engine with both diesel and natural gas flowing into the same engine.[1]
