The location of Ti atom in sodium alanate: an ab initio spin-polarised study
In this work, ab initio spin-polarised Density Functional Theory (DFT) calculations are performed to study the interaction of a Ti atom with a NaAlH4(001) surface. We confirm that an interstitially located Ti atom in the NaAlH4 subsurface is the most energetically favoured configuration as recently reported (Chem. Comm. (17) 2006, 1822). On the NaAlH4(001) surface, the Ti atom is most stable when ...

Hydrogen storage systems for automotive applications: project StorHy
Around two thirds of world's oil usage is associated with transportation with road vehicles consuming around 40%. Also, transportation accounts for around 25% of greenhouse emissions worldwide, with around 90% coming from road vehicles. This situation is further complicated by the fact that oil reserves are running out. For this reason, the automotive industry supported by relevant governing ...

An Ammonia-powered Fuel Cell Electric Golf Cart System
Ammonia (NH3) is a carbon-free hydrogen (H2) carrier, which enables liquid-phase H2 storage and transport under mild conditions. Although the concept of NH3-to-H2 has been frequently proposed, the practical application of NH3 as the energy source for H2 power automotive systems is rarely reported. To close the gap between NH3 supply and H2 utilization, we demonstrated an NH3-powered fuel ...

Using TGA-MS to Explore Novel Hydrogen Carriers for Fuel Cells
Hydrogen (H2) production is pivotal in the global shift towards a net-zero carbon economy. Its elemental abundance and zero-emission combustion position it as an ideal renewable energy source. However, the journey to harness hydrogen’s full potential is fraught with challenges, particularly in storage and transportation. Researching viable hydrogen carriers is critical, as conventional ...

Gaseous release in LiNH2–MgH2 systems
Hydrogen is considered a safe and clean alternative to fossil fuels. Hydrogen storage is currently obtained by compressing the gas at high pressure. Researchers are currently attempting to tackle safety and energy density issues by locking hydrogen into solids, packing large quantities into small volumes. However, most of the known solids (i.e. intermetallics) show very low gravimetric density, ...
