Problem
Industrial and aquaculture operations require large volumes of high‑purity oxygen, but traditional production relies on energy‑intensive, capital‑heavy processes such as cryogenic distillation or pressure‑swing adsorption, which are costly and difficult to deploy at remote sites.
Solution
Nernst offers on‑site oxygen generators that extract oxygen directly from ambient air using proprietary ceramic Oxygen Generation technology and additive‑manufactured Oxygen Transport Membranes. The membrane provides 100 % oxygen selectivity without moving parts, enabling continuous delivery of high‑purity oxygen at scales from under 1 kg to over 100 tons per day. Energy consumption is below 200 kWh per ton of O₂, substantially reducing operating costs compared with legacy methods. The modular design allows rapid scaling and turn‑down ratios exceeding 10×, making the system suitable for both large industrial plants and remote aquaculture facilities. Low‑cost, abundant materials and a maintenance‑free architecture further lower capital expenditures and improve reliability.
Target Audience
Primary customers are industrial manufacturers, energy producers, and aquaculture facilities that require continuous, high‑purity oxygen at scale, especially those operating in remote or off‑grid locations.
