Assessment of sustainable high temperature hydrogen production technologies

High pressure ammonia decomposition on Ru–K/CaO catalysts

“…However, the derived environmental consequences and scarcity issues are a strong driving force to look for cleaner and more sustainable alternatives. [1][2][3] Among the different possibilities, the use of hydrogen offers great advantages [4][5][6][7] especially if its production [8][9][10][11][12] is accompanied by CO 2 capture or if it is directly produced from water.…”

An Integrated Renewable Energy System for the Supply of Electricity and Hydrogen Energy for Road Transportation Which Minimizes Greenhouse Gas Emissions

“…For electrochemical water splitting, hydrogen is produced by using electricity to separate the hydrogen components from water. Electrochemical water splitting with high-temperature electrolysis technology has good efficiency, but there are structural and environmental challenges [11]. Hydrogen production can be carried out more sustainably with catalysts made from chemical waste from the pulping industry [12].…”

A Facile Strategy to Realize Rapid and Heavily Hydrogen-Doped VO2 and Study of Hydrogen Ion Diffusion Behavior

“…4,5 By carrying out hydrogenation treatment, versatile phenomena such as metal− insulator transition, 6−8 enhanced surface plasmon response, 9,10 photocatalysis, 11−13 and hydrogen storage 14−16 have been discovered. However, the traditional hydrogenation methods normally require a high-temperature/pressure reaction, 17,18 atomic hydrogen, 19 noble metal catalysis annealing process, 4,16 or metal-assisted acid treatment, 20−22 while the efficiency of hydrogenation still needs further improvement since the essence of the aforementioned methods demands the conversion from ionic hydrogen to atomic hydrogen.…”
