Hydrogen as an energy carrier is a promising alternative to fossil fuels, and it becomes more popular in developed countries carbon-free fuel. The low boiling temperature of hydrogen (20 K or −253.15 °C) provides unique opportunity implement superconductors with critical above 20 such MgB2 high-temperature superconductors. Superconductors increase efficiency reduce the loss energy, which could ...

Policymakers and global energy models are increasingly looking towards hydrogen as an enabling carrier to decarbonize hard-to-abate sectors (projecting growth in consumption the magnitude of hundreds megatons). Combining scenarios from life cycle impacts different production technologies, results this work show that emissions proposed configurations economy would lead climate overshoot at least...

Hydrogen storage is still one of the most significant issues hindering the development of a "hydrogen energy economy". Ammonia borane is notable for its high hydrogen densities. For the material, one of the main challenges is to release efficiently the maximum amount of the stored hydrogen. Hydrolysis reaction is a promising process by which hydrogen can be easily generated from this compound. ...

Hydrogen demand in refineries is increasing vigorously due to the stringent transportation fuel specifications, furthermore the interest in the so-called hydrogen economy developed in the recent years put the hydrogen as energy carrier in the centre of a growing interest. More than 95% of the hydrogen for refinery use is nowadays produced via hydrocarbon steam reforming, where Foster Wheeler pl...

Storage of hydrogen is one of the key challenges in developing hydrogen economy. Magnesium hydride (MgH2) is an attractive candidate for solid-state hydrogen storage for on-board applications. In this study, 10 wt.% ZrB2 was co-milled with magnesium hydride at different milling times to produce nanocrystalline composite powder. The effect of milling time and additive on the hydrogen desorption...

Abstract In the midst of a climate crisis, alternative and low-carbon energy resources must be put to scale in order achieve carbon emission reductions coming decades. this respect, hydrogen has gained attention as an carrier. Hydrogen can produced from methods that are commonly classified by range colours. However, each source its own challenges terms security, equity, environmental sustainabi...

What are the fuels of the future? Seven representative carbon- and nitrogen-based fuels are evaluated on an energy basis in a power-to-fuel-to-power analysis as possible future chemical hydrogen-storage media. It is intriguing to consider that a nitrogen economy, where hydrogen obtained from water splitting is chemically stored on abundant nitrogen in the form of a nontoxic and safe nitrogen-ba...
