The Price Of Liquid Nitrogen In The United States

By Amir Amirsadeghi RT Resources Last updated 30 Jun 2026

The cost of liquid nitrogen in the United States ranges from $0.13 to $1.78 per liter depending on whether it’s produced on-site or bought from a supplier (delivered in bulk).

• Producing liquid nitrogen on-site is very economical and can cost as low as $0.13 per liter.
• When purchased in bulk from a supplier, LN2 prices vary between $0.51 and $1.78 based on the location.

This article explains the economics behind the two liquid nitrogen supply methods, from investment to hidden costs.

Liquid nitrogen price at a glance (2026)

*All-in cost includes delivery and fuel surcharges, hazmat fees, monthly dewar or tank rental, demurrage, telemetry and monitoring charges, and the 5 to 15% of supply lost to evaporation (off-gassing). Quoted per-liter prices almost never include these.

What you pay comes down mostly to one decision: do you produce nitrogen on-site, or buy it in bulk? Volume, location, purity, and container type matter too, but that first choice drives everything else.

The cost of liquid nitrogen produced on-site

To calculate the true cost of on-site LN2, account for three things: the generator (a one-time investment spread over its life), electricity, and maintenance.

1. The generator (a one-time investment)

A liquid nitrogen generator is a one-time purchase, and what it costs depends on how much you need to produce. As a rough guide, a 10 L/day unit sized for a clinic or single lab runs around $45,000, a 30 L/day unit for a busier lab around $80,000, and high-capacity industrial systems climb well into six figures.

The sticker isn’t the number to fixate on, though. A generator lasts well over ten years, so a simple way to budget it is to count about 10% of its cost per year as the capital part of your nitrogen bill. Spread that way, even a larger unit only adds a small amount to your cost per liter, and once it’s paid off that part falls away entirely. The exact figure depends on your daily usage and how the system is configured.

2. Running cost: how much does it cost to run a liquid nitrogen generator?

Liquefying nitrogen is energy-intensive, and electricity is the main operating cost. An efficient mid-size generator uses roughly 1 to 1.5 kWh of electricity per liter of LN2 produced (compact units draw more per liter, large plants draw less).

At the 2026 US commercial average of about 14¢/kWh, that works out to roughly $0.14 to $0.21 per liter. Power rates vary a lot by state, so your cost will too:

Smart features cut this further: many generators only make LN2 when storage drops below a set threshold, and pressure-boost and no-loss designs raise yield without extra power. Units can also be scheduled to run on cheaper off-peak power.

3. Maintenance cost

Maintenance is modest and largely in-house. Routine servicing averages around $1,000 per year. A standard service kit runs about $650 and includes filters and electrical components like fuses and relays that in-house staff can fit with basic training. More involved servicing is handled by a technician, and units with remote diagnostics can usually be sorted out without a site visit.

Your true on-site cost per liter

Put those three together (equipment spread over its life, plus electricity and maintenance) and most facilities end up paying $0.13 to $0.40 per liter, with the lowest figures at high volume on cheap power.

The real cost of buying nitrogen in bulk

Bulk looks cheap on the quote. The invoice is another matter. Suppliers make LN2 for less than $0.002 a liter and charge $0.50 to $1.78 for it, then add a stack of costs the headline rate leaves out. Storage piles on more, since a new 230 L dewar runs about $4,500 to buy and a fixed tank brings permits, a plinth, and installation. And none of it stands still: bulk prices have gone up about twice a year for the last five years.

The hidden costs most buyers miss

Bulk LN2 quotes almost never include:

• Evaporation: liquid nitrogen keeps boiling off in storage, commonly 5 to 15% of your supply. You pay for it but never use it.
• Delivery and fuel surcharges: roughly $35 to $50 per delivery, tied to oil prices.
• Dewar or tank rental: a fixed monthly cost no matter how much you use.
• Telemetry fees: often $75 to $100 per month to track tank levels.
• Hazmat fees, demurrage, taxes, and tank-inspection charges.
• Contract lock-in: agreements often carry evergreen terms or long cancellation windows (e.g. 12 months’ notice).
• Admin time: someone has to forecast usage, schedule deliveries, monitor tank levels, and chase the supplier when a drop runs late. That work has a cost too.
• Downtime risk: a missed delivery can halt production, and that cost lands on you, not the supplier.

Together these push the real delivered cost to $2 to $5 per liter, well above the rate you were quoted.

What a real liquid nitrogen quote looks like

A liquid nitrogen quote almost never tells you what you’ll actually pay. The headline rate is just the gas. Everything else lands underneath it. Take a typical month for a lab buying around 900 liters through rented dewars at a “$1.20 per liter” rate:

And it gets worse, because about 12% of that nitrogen, roughly 108 liters, boils off before anyone touches it. So you’re really paying $1,505 for about 790 usable liters. That’s close to $1.90 a liter, not the $1.20 on the quote. One missed delivery or one annual price increase and you’re past $2.

Generator vs bulk delivery: a real cost comparison

Numbers make this real, so take a facility using 30 liters a day, a typical mid-size lab or clinic. And put it somewhere bulk nitrogen is expensive, like McAllen, Texas, which sits a long way from the nearest large air-separation plant and gets hit with distance and fuel surcharges on every delivery.

At 30 liters a day you’re going through about 11,000 liters a year. In a market like McAllen, once you add those surcharges, dewar rental, and the nitrogen that boils off between deliveries, an all-in delivered price around $3 a liter is realistic. That’s roughly $33,000 a year, and it climbs with every price increase.

Now produce it on-site with a Titan 30. Electricity runs about $0.15 to $0.20 a liter, maintenance adds a little, and counting the generator at about 10% of its cost a year, your all-in on-site cost lands near $0.95 a liter. That’s around $10,600 a year. Once the generator is paid off, your cost drops closer to $0.27 a liter.

That’s about $22,000 a year back in your pocket, and the generator pays for itself in a little over three years. After that the gap only gets wider, because your bulk price keeps rising while your on-site cost keeps falling.

Real savings: the IVF Michigan example

IVF Michigan, a bio-storage clinic, used to order 4 × 230 L dewars every week from a supplier. After installing a single Rutherford & Titan 60 L/day generator, they cut that recurring spend and now save about $35,000 a year, with an always-available supply on top. In their words: “Such an easy system to use, and we save about $35K a year from using it.”
