Gas Cost
What Drives Cost Per Cubic Meter in Industrial Gas and Cryogenic Delivery
Where the money actually goes in gas production and cryogenic delivery, and how to build a per unit quote that survives a customer audit.
For merchant gas the largest single cost is electricity, not the gas itself, since air is free. An air separation unit consumes roughly 0.5 to 0.6 kilowatt hours per cubic meter of gaseous nitrogen and closer to 0.6 to 0.7 for oxygen. At an industrial power rate of 9 cents per kWh, that is about 5.4 cents of energy in every cubic meter before you touch labor, cylinder handling, or margin. Power alone can be 55 to 70 percent of production cost, so a two cent per kWh swing in your utility contract moves the floor price more than any labor efficiency project you can run.
Cryogenic product carries a boil-off tax that estimators routinely forget. Liquid lost to evaporation between the plant and the customer meter is product you paid to make but never sold. At 0.3 to 0.5 percent per day across storage and transport, a five day supply chain quietly erases 1.5 to 2.5 percent of liquid volume. Run the Cryogenic Boil-Off Loss tool against your actual tank heat leak and dwell time, then add that percentage straight onto delivered cost. Quotes that price the liquid at plant volume, not delivered volume, lose margin on every drop that vaporized in transit.
Cylinder gas cost is dominated by handling and asset turns, not the molecules inside. A 10 cubic meter cylinder might hold 60 cents of nitrogen but cost 4 to 6 dollars to fill, inspect, and stage once you load labor at 28 to 35 dollars per hour, plus valve and hydrostatic testing amortized across the cylinder life. Use the Cylinder Fill Cycle Time and Valve Refurbishment Cost tools to pin the per fill labor. If a cylinder only turns 4 times a year instead of 6, you spread the same fleet ownership cost across a third fewer sales, and unit cost rises accordingly.
Delivery is where bulk economics live or die, and the driver is route density. A bulk tanker delivery costs 4 to 7 dollars per loaded mile all in, so a 160 mile round trip carries 640 to over 1,100 dollars of transport before the product margin. Spread across a full 20 ton drop the freight is trivial per cubic meter, but a half empty tanker doubles it. The Bulk Tank Delivery Cost and Route Density Margin tools let you test whether a distant single customer stop actually clears its delivery cost or bleeds the route.
Overhead in this industry is unusually heavy because of compliance and safety. DOT cylinder requalification, PED or ASME vessel inspections, gas purity verification, and safety audits are non negotiable fixed costs. A mid size fill plant can carry 8 to 15 percent of revenue in inspection, testing, and certification labor alone. Feed your test cadence into the Gas Purity Test Workload and Safety Inspection Workload tools, then load that as a burden rate. Estimators who bury compliance inside a vague overhead percentage almost always understate it and quote too low on specialty and medical grades.
Build the quote bottom up in four layers so it survives a customer challenge. Layer one is molecule cost, power plus feedstock. Layer two is conversion, fill labor and cylinder or tank handling. Layer three is logistics, the delivered mile cost from the route tools. Layer four is compliance and margin. A defensible nitrogen cylinder quote might read 0.6 cents molecule, 50 cents fill labor, 40 cents logistics, 30 cents compliance and asset, then margin, landing near 1.80 to 2.20 dollars per cubic meter delivered. Specialty blends add feedstock and purity testing on top.
Estimates go wrong in predictable places. The three most common leaks are pricing liquid at plant volume instead of delivered volume, assuming cylinders turn faster than they do, and treating a marginal delivery stop as free because the truck was going that direction anyway. Each quietly costs 3 to 8 percent of margin. Use the Gas Blending Cost tool for specialty mixes so a small percentage of an expensive component like helium or a calibration gas does not get averaged away. The discipline is simple: price what you deliver and sell, not what you made.
