“Believe it or not we’ve been doing this since 1979,” Norm says. The business has filled a lot of orders for Indiana University graduations over the years.

Norm Ladd is spending his morning filling white balloons with helium. That’s causing prices to climb and researchers to worry. Geological Survey, demand for helium has increased over the past several years. Helium is the second most abundant element in the universe, but there’s a limited supply here on earth and a ccording to the U.S. Barbara BrosherĪn element that plays a critical role in science and medicine is becoming harder and harder to find. “The amount of hydrogen generated by the continental crust over the last 1 billion years could power society’s energy needs for over 100,000 years,” Chris Ballentine from the University of Oxford and the study’s co-author, said in a statement.The owners of Blast Off Balloons say they're paying five to six times more for helium than they were ten years ago. Hydrogen-rich underground deposits, the researchers said, could provide an alternative carbon-free source. Natural gas is currently the primary source of hydrogen production, according to the International Energy Agency. Their model showed that energy generated from the radioactive decay of uranium and thorium could split water to form hydrogen. These rocks could also be a source of hydrogen.

Helium, too, migrates from the water into the bubble phase. Similarly, when nitrogen concentration is high enough, it will form bubbles. This could provide a route, the author said.įor example, in sparkling water, the gas bubbles out because its concentration in the water is higher than its solubility. Nitrogen and helium are co-produced from crystalline basement rocks. Cheng said that separating helium from water is quite expensive.īut previous studies provided a clue. The helium dissolves in water present in rock pores. They have also existed for millions or billions of years, allowing large amounts of helium to be produced and stored,” Cheng said. These rocks naturally contain uranium and thorium, both of which decay to form helium naturally. The gas can be produced and stored in crystalline basement rocks, dense rocks that extend from the mantle to the near-surface or surface, according to the model. Cheng and her colleagues wanted to locate new reservoirs of carbon-free helium using a model. This process also comes with a high carbon footprint as helium production is related to drilled natural gas or oil.
“If helium concentration in the drilled gas exceeds 0.3 per cent, it is economically favourable to add another step to separate helium from natural gas,” Anran Cheng from the University of Oxford and the lead author of the study, told Down To Earth. This gas is typically produced as a byproduct of natural gas production.

The prices of helium have skyrocketed in recent years due to shortage. The market for helium is valued at $6 billion, with the gas finding applications in MRI scanners, computer chips and fibre optics manufacturing and nuclear applications.
Researchers have proposed a new model that could help the world tap into helium reserves to address shortage issues, the study published in Nature journal highlighted. But reservoirs of this gas, with no carbon footprint, likely exist in geological formations beneath the Earth, according to a new study. Helium, the second most abundant element in the universe, is in short supply on Earth.
