Replacing Liquid Oxygen (LOX) Deliveries at Biogas & RNG Sites
Biogas and RNG facilities that rely on delivered liquid oxygen (LOX) tie a continuous desulfurization process to a delivery schedule — and pay for gas they never use. On-site generation removes the deliveries, the stored pressurized liquid, and the evaporation loss entirely.
No stored pressurized liquid on a combustible-gas site
Biogas and RNG facilities handle combustible gas, so most operators would rather not keep pressurized liquid oxygen and cylinder storage on site. An ON2 plant generates oxygen from ambient air as the process needs it, so there is no bulk liquid oxygen vessel to site, permit, and manage next to the gas system.
Stop paying for oxygen that evaporates
Liquid oxygen evaporates in storage — especially in warm weather — so with delivered LOX you pay for gas that boils off before you ever use it. On-site generation makes oxygen on demand from ambient air, so you only run the plant, and its electricity, for the oxygen your process actually consumes.
Cut the delivery schedule loose
Delivered oxygen ties a continuous biological process to truck schedules, vendor contracts, and site access — a particular challenge for rural and remote biogas sites. An on-site plant produces oxygen at your fence line on demand and ships with hospital-grade remote monitoring — purity, CO₂, temperature, and contamination alerts — so you can confirm supply from your control room instead of tracking a delivery window.
Own the supply instead of renting it
Delivered LOX is a perpetual operating expense that scales with usage and hauling distance. On-site generation converts that recurring cost into equipment you own — purchased outright or leased-to-own over 5 or 7 years — with electricity as the main operating input. ON2 plants deliver 90–95% purity at 0–50 psi, are made in the USA in an ISO 13485 facility, and have been built by ON2 since 1984.

Frequently asked questions
Why replace liquid oxygen deliveries at a biogas site?
Biogas and RNG sites handle combustible gas, so most operators avoid storing pressurized liquid oxygen and cylinders on site. Liquid oxygen also evaporates in storage, especially in warm weather, so you pay for gas you never use. On-site generation from ambient air eliminates deliveries, stored pressurized liquid, and per-delivery pricing.
What does an on-site oxygen plant need to run instead of deliveries?
Electric power and ambient air. The plant generates oxygen on site as the process needs it and ships with hospital-grade remote monitoring, so there are no deliveries or storage vessels to manage.
What purity and pressure does the on-site plant deliver?
ON2 plants deliver 90–95% oxygen purity with delivery pressure adjustable from 0 to 50 psi, matched to your desulfurization process and injection point.
Can we lease the oxygen plant instead of buying it?
Yes. ON2 offers lease-to-own over 5 or 7 years alongside direct purchase, so you can spread the cost into predictable payments and keep capital available for the rest of the project.
