ASP Isotopes Achieves Stable Liquid Helium Production in South Africa
Key Facts
ASP Isotopes announced that Renergen subsidiary Tetra4 has completed commissioning and achieved stable liquid helium production at the Virginia gas project in South Africa. The announcement marks the project’s move from preparation to production, but does not mean full operations have begun or commercial shipments have been delivered. The company said liquid helium is currently accumulating in Tetra4’s refrigerated tanks ahead of initial deliveries under existing offtake agreements. Paul Mann added that the company is ramping up production toward nameplate capacity and completing logistics arrangements with buyers for the first delivery. The next phase will therefore focus on increasing production and preparing shipments, following the announcement of stable initial production.
ASP expects Phase 1 to produce about 70,000 cubic feet per day of liquid helium, alongside 2,500 gigajoules per day of liquefied natural gas. Mann said nameplate capacity is expected in the fourth quarter of 2026, with production ramp-up continuing now. This timeline distinguishes the achievement of stable production from reaching the planned production level; the company has not said the project has already reached nameplate capacity. In an August 20 statement, ASP had forecast commercial production beginning in the third quarter of 2026 and said the first commercial helium shipment was expected in September. The October 26 announcement sets out the subsequent status: stable production, accumulation in storage and completion of delivery arrangements, while reaching nameplate capacity is now targeted for the fourth quarter.
The company expects annualized revenue to exceed $27 million after completion of Phase 1. That estimate is based on an assumed liquefied natural gas price of between $15 and $18 per gigajoule and an average liquid helium price of $600 per thousand cubic feet. The projected revenue remains conditional on those prices being achieved, Phase 1 being completed and production being ramped up; it is a company estimate, not revenue already generated. In its August statement, ASP said binding take-or-pay contracts cover about 75% of planned Phase 1 liquefied natural gas volume and 15% of helium volume. In June, it also announced a five-year take-or-pay helium sales agreement at a base price exceeding $600 per thousand cubic feet of contained helium.
The Virginia project holds South Africa’s first onshore petroleum production right and is the country’s first integrated project to produce liquid helium and liquefied natural gas, according to ASP. The development comes as the U.S. Department of Energy on October 23 described helium as a critical material under the Energy Act of 2020, citing global demand growing faster than production, as well as refining capacity constraints and lengthy permitting procedures that limit U.S. production. The department said the designation could enable greater federal financing for helium producers and increase government monitoring of supplies. Reuters reported in March that helium shortages had begun to affect production at some technology supply chains and that transportation delays had worsened the impact of tight supplies. According to U.S. Geological Survey data cited by Reuters, Qatar produces nearly one-third of global supplies; Russia also imposed temporary restrictions on helium exports in April to protect domestic supplies.
On expansion, ASP estimated that Phase 2 of the Virginia project is about 13 times larger than Phase 1 and said it expects construction to begin in the second half of 2026. The company said it has conditional approval for senior debt financing of up to $750 million for Phase 2. An August 4 shareholder letter had referred to negotiations over long-term helium and hydrocarbon supply agreements, with terms ranging from 5 to 15 years. The stock closed at $1.95 on October 23, according to EL7 data. The available data did not include the session high or low.
