Nitrogen is a common catalyst used in many processes, but iodine-130 is particularly good at creating hydrogen.

However, the chemical is also a very reactive element and needs to be stored and disposed of in a safe manner.

Researchers at the University of Texas at Austin have developed a new approach that allows for the efficient and safe storage of iodine-129 and its derivative iodine-132 in a liquid electrolyte.

The researchers also developed a method to separate the iodine-137 and iodine-134, two other important hydrogen-forming products.
