Prices of hydrogen produced by distributed steam methane reforming, as predicted by H2A Production Model from United States Department of Energy, [9] assuming price of natural gas of US$3/MMBtu (US$10/MWh; US$0.10/m 3). Does not include cost of storage and distribution. 1: 2 H (D) Deuterium: 0.0001667 [10] 13 400: 2.23: 2020: CIL [11]
Helium is the least water-soluble monatomic gas, [96] and one of the least water-soluble of any gas (CF 4, SF 6, and C 4 F 8 have lower mole fraction solubilities: 0.3802, 0.4394, and 0.2372 x 2 /10 −5, respectively, versus helium's 0.70797 x 2 /10 −5), [97] and helium's index of refraction is closer to unity than that of any other gas.

Map showing helium-rich gas fields and helium processing plants in the United States, 2012. From USGS. Helium production in the United States totaled 73 million cubic meters in 2014. The US was the world's largest helium producer, providing 40 percent of world supply. In addition, the US federal government sold 30 million cubic meters from storage.
At the time of writing, the national average price of regular gas is $3.62 per gallon, $0.02 higher than this time last year. Drivers who use premium gas are paying $0.07 more this year than last ...
The highest gas prices in U.S. history may have occurred in 2022, but the future of what you will pay at the pump remains ominous for the rest of 2023 and for the next several years.
The chart shows a 75-year history of annual United States natural gas production and average wellhead prices from 1930 through 2005. Prices paid by consumers were increased above those levels by processing and distribution costs.
For that reason, it is an attractive gas for lifting as well. A major advantage is that this gas is noncombustible. But the use of helium has some disadvantages, too: The diffusion issue shared with hydrogen (though, as helium's molecular radius (138 pm) is smaller, it diffuses through more materials than hydrogen [4]). Helium is expensive.
American drivers had it rough back in 1981. The average price of gasoline spiked to $1.353 a gallon that year -- up from $1.221 in 1980 and more than double the price just three years earlier....
