An oxygen plant designed for a large industrial complex may be a poor fit for a smaller or remote user. NETL’s OASIS team spent part of 2026 examining that gap as it sought a market for materials that separate oxygen from air.
The National Energy Technology Laboratory reported on October 6 that the team had completed Energy I-Corps commercialization training. OASIS—O₂ from Air Separation at Intermediate Scales—targets on-site supply for small and moderately sized applications.
Its central component is a perovskite oxide, a material with a structure that can repeatedly take up and release oxygen. NETL reported oxygen purity ranging from 95 percent to more than 99 percent.
The laboratory’s technology-transfer description identifies oxygen carriers made from strontium, calcium and iron, with optional nickel substitution. Reversible capture and release at moderate temperatures could support compact, modular systems without cryogenic separation, the very low-temperature process used in large oxygen plants.
A user would need the system to meet a particular volume, purity and cost requirement. NETL’s reported purity is one part of that comparison; the records do not establish installed commercial output or a full operating-cost comparison.
The October account described customer discovery and a refined market strategy. NETL also offered the underlying invention for licensing or collaborative research, giving a prospective partner a route to develop an application.
