US Federal Helium Reserve (Cliffside Field, TX)

US Bureau of Land Management (BLM) Federal Helium Program reserve. The Cliffside field near Amarillo, TX was the world's largest helium storage reservoir; depleted significantly over decades. BLM privatized helium operations in 2023 per the Helium Stewardship Act. As of 2024 the reserve is largely depleted; final BLM helium auction completed in 2024. This ends the US federal backstop for helium supply — making Qatar and Australia the primary strategic sources.
