Fuel Options for Off-Grid Industrial Facilities

Four common options exist for an industrial facility with no pipeline connection: diesel, propane, trucked LNG and trucked CNG. Consumption, distance from supply and how long the site will need the fuel settle almost every case.

Four off-grid fuel choices

  • Diesel: simplest to start and usually the most expensive per unit of energy, so it suits low or intermittent load.
  • Propane: cheaper per unit and simple to store, suiting moderate load.
  • LNG: holds far more energy per truckload, so it wins at high continuous load and is punished least by distance.
  • CNG: suits lower volumes and shorter distances.

What determines the fit

The load profile, distance from supply, and expected duration matter more than a generic fuel ranking. A short-term or intermittent site may value simple storage and fast startup. A high continuous load benefits from the energy density of LNG, while a lower-volume site closer to supply may fit CNG or propane.
