Catalytic hydrogen storage in liquid hydrogen carriers

Abstract

Hydrogen energy, often dubbed the "ultimate energy source", boasts zero carbon emissions and no harmful by-products. Nevertheless, the storage and transportation of hydrogen remain significant hurdles for its commercialization and...

Iron oxide-promoted photochemical oxygen reduction to hydrogen peroxide (H2O2)

“…ammonia or formic acid). 19–29 Pure H 2 stored in a tank at 35 MPa (room temperature) delivers 2.8 MJ L −1 when operated in a fuel cell, which is very similar to the energy density of aqueous H 2 O 2 (70 wt%) with 3.1 MJ L −1 . 30,31 Thus H 2 O 2 , being fully soluble in water, offers an easy-to-handle liquid fuel alternative achieving safer operation, storage and transportation.…”

A Perspective Review on N-Heterocycles as Liquid Organic Hydrogen Carriers and Their Hydrogenation/Dehydrogenation Catalysts

“…On the other hand, N-heterocycles have lower dehydrogenation enthalpy, vapor pressure, safety and biodegradability, making them more suitable LOHCs than aromatic molecules, so N-heterocyclic LOHC systems have received more attention in recent years. 93…”

“…While DBT is considered the most suitable aromatic LOHC, its high dehydrogenation temperature and high viscosity can burden pump delivery. On the other hand, N-heterocycles have lower dehydrogenation enthalpy, vapor pressure, safety and biodegradability, making them more suitable LOHCs than aromatic molecules, so N-heterocyclic LOHC systems have received more attention in recent years …”

Theoretical insights into H2O adsorption on CuAlO2(112̄0) surfaces: from low to high coverage

“…2–5 Methanol with a high H to C ratio and low bond energies is a promising hydrogen carrier candidate for the future. 6,7 Methanol steam reforming (MSR, CH 3 OH + H 2 O → CO 2 + 3H 2 ) is an established process known for its low reforming temperatures (60–300 °C), high hydrogen yield, and commendable efficiency. In MSR technology, both noble metal and non-precious metal catalysts are utilized.…”
