US Designates Helium As a Critical Material

An anonymous reader quotes a report from the Associated Press: The U.S. designated helium as a critical material on Friday because it’s indispensable for making semiconductors that are essential to energy generation, and the global supply is at risk of disruption, according to the Energy Department. The designation by the Energy Department means that more federal financing will be available for helium producers and that the government will monitor it more closely. Helium is primarily produced as a byproduct of natural gas processing. The United States is the world’s largest producer of natural gas and of helium. Qatar and Russia are the other top helium producers.

[…] Helium makes balloons rise, but that’s not why the DOE is interested in it. Helium plays an important role in wind, solar and nuclear energy production, space exploration, medical imaging and research. Assistant Secretary of Energy Audrey Robertson said helium’s unique properties make it irreplaceable, such as the fact that it’s non-combustible and has the lowest boiling point of any gas. The nation needs an ample supply for semiconductors, quantum and super computing, and superconducting magnets, added Robertson, who oversees the Office of Critical Minerals and Energy Innovation.

[…] Despite environmental concerns with recovering helium from natural gas, there are also opportunities, said Greeshma Gadikota, director of the Lenfast Center for Sustainable Energy at Columbia University. “If we burn the natural gas, there are a lot of CO2 emissions associated with that,” Gadikota said. “But if you just extract the helium and use it, the uses of it don’t contribute necessarily to greenhouse gas emissions. “So from a climate standpoint, if we are going to continue down the line of extracting natural gas and recovering helium,” she added, “I would prefer to see natural gas being used in a form where we directly produce hydrogen and we produce solid carbon.” Hydrogen is a clean burning fuel, and solid carbon can provide permanent carbon sequestration and can be used widely in industrial applications, including rubber and pigments.
