Newly developed tech makes hydrogen without CO2 emissions
By Koh Hyunjeong
Domestic scientists have developed a technology to more effectively produce turquoise hydrogen by using a liquid metal catalyst (NiBiSe, CuBiSe) with added selenium (Se).
A research team led by Han Seung Ju from the Korea Research Institute of Chemical Technology on Feb. 9 said it raised the production process capacity for turquoise hydrogen by using a metal catalyst that maintains liquid form instead of the previous solid catalyst.
Formed through the thermal decomposition of methane (CH4), turquoise hydrogen is categorized as a clean and eco-friendly hydrogen as its production process emits no CO2.
The newly proposed liquid metal catalysts NiBiSe and CuBiSe improved the conversion rate of turning methane into hydrogen 36.3% and 20.5%, respectively, from those of their solid counterparts NiBi and CuBi. The study confirmed the potential to greatly accelerate the commercial production of clean hydrogen.
The team said,
This is expected to make a major contribution to overcoming the limits of existing technology to produce turquoise hydrogen and achieving carbon neutrality.
