LNG vs Propane for Industrial Fuel
Propane stores easily at ambient temperature under modest pressure, making it the simple choice for small and intermittent loads. LNG requires cryogenic handling but delivers natural gas, which emits about 117 pounds of CO2 per million Btu versus about 139 for propane per EIA coefficients, and has generally cost less per unit of energy. For large continuous demand, LNG usually wins on both cost and emissions.
Storage and handling
Propane liquefies under pressure alone, so tanks are cheap and unmonitored sites are common. LNG needs vacuum insulated cryogenic tanks and boil off management, which providers supply as a leased service. Below roughly a few hundred gallons per day of equivalent demand, propane's simplicity usually prevails; above it, LNG logistics scale better.
Cost and emissions
Propane prices track natural gas liquids and crude markets, and per unit of energy propane has generally cost more than natural gas in U.S. markets. On emissions, EIA coefficients put propane at about 139 pounds of CO2 per million Btu against about 117 for natural gas, roughly 16 percent higher. Large propane users converting to LNG typically cut both fuel spend and reported emissions.
Equipment compatibility
Many burners and engines are convertible between propane and natural gas with orifice and control changes, since both are gaseous fuels at the burner tip. Facilities planning an eventual pipeline connection often prefer LNG because no second conversion is needed when pipeline gas arrives.
VP Ventures supplies both delivered LNG programs and wholesale propane, so it can price either side of this comparison for a specific site and load.
Frequently asked questions
When is propane the better choice?
Small, intermittent, or widely scattered loads where cheap ambient storage outweighs the higher fuel cost per unit of energy.
When does LNG beat propane?
Large continuous loads, sites planning a future pipeline connection, and users targeting lower fuel cost and CO2 per unit of energy.
Can equipment switch between propane and natural gas?
Usually yes with burner modifications, since both burn as gases. Confirm with the equipment manufacturer.
Which has lower emissions?
Natural gas, at about 117 pounds of CO2 per million Btu versus about 139 for propane, per EIA.
