Proton Green is a small natural resource company that extracts and sells helium and beverage-grade CO2 from its St. Johns Field in Apache County, Arizona. The St. Johns Field is the foundation of the entire business, containing both helium and CO2 reserves that Proton Green extracts, processes on-site, and sells to industrial offtakers under contract. Proton Green installed its first helium processing plant at St. Johns in mid-2023 and began generating helium revenue in Q3 2023. The plant currently processes approximately 4 million cubic feet per day of inlet gas, with plans to expand to 20 million cubic feet per day. Helium is sold under offtake agreements — currently to a single offtaker — with negotiations underway to add more. The CO2 business has not yet generated revenue; Proton Green is still conducting engineering studies for modular beverage-grade CO2 liquefaction plants, each capable of processing up to 500 tons per day. The business model is capital-intensive: Proton Green invests in wells, processing plants, and permits before revenue flows, and expansion depends on both internally generated cash flow and external financing. Proton Green is also part of a consortium awarded a potential ~$11.6M U.S. Department of Energy grant to develop a regional Direct Air Capture hub, under which Proton Green would provide CO2 storage capacity at St. Johns. Proton Green operates with 11 employees and emerged from a reverse acquisition completed in mid-2023.
