Special Issue Information

Dear Colleagues,

Production of low-carbon alternative fuels is an important pathway to combat climate change and control global warming. Sustainable production of low-carbon hydrogen accelerates the push towards carbon neutrality. A variety of methods are proposed and are being developed for more sustainable and efficient hydrogen production based on available infrastructure, economic considerations and technological feasibility. Green, blue, and purple hydrogen are examples of low-carbon hydrogen types to be developed to substitute the current grey hydrogen production worldwide. Hydrogen can also be employed as a decarbonizing agent for heavy industries such as cement and steel, or as a storage medium for renewable electricity grids for better stability. This issue supports research on recent advances in all types of sustainable hydrogen production methods including biological and thermochemical hydrogen production, the role of hydrogen in energy transition, and also energy systems where hydrogen is produced and employed for better sustainability. Some of the topics covered in this issue (but not limited to) are as follows:

  • The role of hydrogen in energy transition;
  • Green hydrogen production technologies;
  • Blue hydrogen production technologies;
  • Biomass-based hydrogen production;
  • Power to gas technology;
  • Solar-based hydrogen production;
  • Integrated hydrogen energy systems;
  • Thermochemical water splitting cycles.

Hydrogen addition affects the composition of exhaust gases in vehicles. However, the effects of hydrogen addition to compression ignition engines in running vehicles have not been evaluated. Hydrogen-mixed air was introduced into the air intake of a truck equipped with a direct-injection diesel engine and running on a chassis dynamometer to investigate the effect of hydrogen addition on fuel consumption and exhaust gas components. The reduction in diesel consumption and the increase in hydrogen energy share (HES) showed almost linear dependence, where the percentage decrease in diesel consumption is approximately 0.6 × HES. The percentage reduction of CO2 showed a one-to-one relationship to the reduction in diesel consumption. The reduction in emissions of CO, PM, and hydrocarbons (except for ethylene) had one to one or a larger correlation with the reduction of diesel consumption. On the other hand, it was observed that NOx emissions increased, and the percentage increase of NOx was 1.5~2.0 times that of HES. The requirement for total energy supply was more when hydrogen was added than for diesel alone. In the actual running mode, only 50% of the energy of added hydrogen was used to power the truck. As no adjustments were made to the engine in this experiment, a possible disadvantage that could be improved by adjusting the combustion conditions. Full article

Biodiesel production through transesterification results in a large quantity of crude glycerol as a byproduct, the utilization of which is technically and economically challenging. Because of the ability to efficiently process wet feedstocks, supercritical water gasification (SCWG) is utilized in this study to convert crude glycerol into hydrogen-rich syngas. A significant challenge addressed through this study is the decomposition routes of different heterogeneous components of crude glycerol during SCWG. Pure glycerol, methanol and oleic acid were investigated for SCWG as the model compounds of crude glycerol. SCWG of model compounds at temperature, pressure, feedstock concentration and reaction time of 500 °C, 23–25 MPa, 10 wt% and 1 h, respectively, revealed methanol to exhibit the highest H2 yield of 7.7 mmol/g, followed by pure glycerol (4.4 mmol/g) and oleic acid (1.1 mmol/g). The effects of feedstock concentration from 30 wt% to 10 wt% increased H2 yield from all model compounds. Response surface methodology (RSM) was used to develop a response curve to visualize the interactive behavior and develop model equations for the prediction of H2-rich gas yields as a function of the composition of model compounds in the crude glycerol mixture. Predictive models showed a good agreement with experimental results, demonstrating high accuracy and robustness of the model. These findings demonstrated a strong potential of crude glycerol for SCWG to generate H2-rich syngas. Full article
