Omani researcher’s process cuts the energy needed to purify and liquefy biohydrogen
Nawaar Al Amri’s integrated process lowered energy use to nearly 7.5 kWh per kg of hydrogen and won a National Research Award.
Nawaar Nasser Al Amri, a business excellence specialist at Integrated Gas Company, won the National Research Award in the Energy and Industry category for young researchers.
Her study describes an integrated process for purifying and liquefying hydrogen-rich gas derived from biomass. It uses cryogenic anti-sublimation to separate carbon dioxide while the hydrogen stays gaseous. Energy consumption fell from 9.62 to nearly 7.5 kWh per kg of hydrogen, and energy efficiency rose from 31.5% to 41.3%; conventional systems typically need 12 to 15 kWh per kg. The liquid hydrogen reached a para-hydrogen content above 99%, and the study also reports lower capital and operating costs.
The paper appeared in Process Safety and Environmental Protection, with co-authors Dr Muhammad Abdul Qyyum, Dr Junaid Haider, Dr Ahmad Naquash and Prof. Ala’a Al Muhtaseb. It supports Oman Vision 2040 and the national goal of net-zero emissions by 2050.
