Hydrogen Clathrates: Next Generation Hydrogen Storage Materials

Energy Storage Materials, 2021
Abstract Extensive research has been carried on the molecular adsorption in high surface area materials such as carbonaceous materials and MOFs as well as atomic bonded hydrogen in metals and alloys. Clathrates stand among the ones to be recently suggested for hydrogen storage. Although, the simulations predict lower capacity than the expected by the

Theoretical Thermodynamic Efficiency Limit of Isothermal Solar Fuel Generation from H₂O/CO₂ Splitting in Membrane Reactors

Molecules, 2021
Solar fuel generation from thermochemical H2O or CO2 splitting is a promising and attractive approach for harvesting fuel without CO2 emissions. Yet, low conversion and high reaction temperature restrict its application.

Hydrogen Generation by Hydrolysis of Magnesium Hydride in Organic Acids Solutions [PDF]

, 2023
Hydrolysis of MgH2 has a high theoretical hydrogen yield (15.2%) and is very attractive for onsite hydrogen production. However, the low solubility of Mg(OH)2 causes sluggish kinetics and incomplete utilization of MgH2.
