This paper experimentally investigated the co-effect of cylinder cutoff and hydrogen addition … engine equipped with an electronically controlled hydrogen injection system and a hybrid electronic control unit. The engine …, respectively. For each cylinder closing strategy, the hydrogen energy fraction in the total fuel (βH2) was increased from 0% to …

This study deals with solar hydrogen production from the two-step iron oxide thermochemical cycle (Fe3O4/FeO). This … exothermic steam hydrolysis of the reduced metal oxide (wustite) for hydrogen generation. Thermodynamic and experimental … investigations have been performed to quantify the performances of this cycle for hydrogen production. High-temperature decomposition …

Hydrogen, a promising and clean energy carrier, could potentially replace the use of fossil fuels in the transportation … sector. Currently, no environmentally attractive, large-scale, low-cost and high-efficiency hydrogen production process is … for CO2-free production of hydrogen. The method is environmentally friendly since it uses only water and solar energy …

This paper compared the effects of hydrogen and hydrogen–oxygen blends (hydroxygen) additions on the performance of a … engine equipped with a hydrogen and oxygen injection system. A hybrid electronic control unit was applied to adjust the … hydrogen and hydroxygen volume fractions in the intake increasing from 0% to about 3% and keep the hydrogen-to-oxygen mole …
