How many people know that deep-sea microorganisms make hydrogen, which is attracting attention as future energy without carbon emission. In addition, a new technology to extract hydrogen from ammonia has been discovered.

Researchers at the Korea Institute of Ocean Science and Technology (KIOST) have been promoting’dreaming of the future’ as part of the marine science popularization project, including the process of producing biohydrogen using the archaebacteria’Thermococcus onnurinus NA1′ found in the deep sea water pit in the South Pacific in 2002. It was announced on the 11th that it was published as Volume 35 of the’Marine Bookstore’ series, Biohydrogen Made by Small Superpowers.

KIOST has successively identified the mechanism of NA1 hydrogen production (2010) and energy generation (2014) and succeeded in developing 156T, a high-value-added biohydrogen production strain using NA1 in 2016. Since then, in January of this year, it has completed the development of technology for commercialization of biohydrogen production using marine archaebacteria, securing world-class biohydrogen productivity and source technology.

Earlier on the 6th, Dr. Young-Seok Cho and Chang-won Yoon’s team at the Korea Institute of Science and Technology (KIST) announced that they developed a technology to generate electricity by extracting high-purity hydrogen from ammonia.

Ammonia can store 1.5 times more hydrogen than the same amount of liquid hydrogen, and does not emit carbon dioxide at all in the hydrogen production process. The research team developed a catalyst that decomposes hydrogen and nitrogen from ammonia and a separator material that can be produced inexpensively, allowing hydrogen to be produced from ammonia and extracted with high purity through the separator. By using this membrane, the decomposition reaction temperature was reduced from 550 degrees to 450 degrees, reducing energy consumption and doubling the production speed, the research team explained.
