A multifaceted approach to hydrogen storage

Abstract

The widespread adoption of hydrogen as an energy carrier could bring significant benefits, but only if a number of currently intractable problems can be overcome. Not the least of these is the problem of storage, particularly when aimed at use onboard light-vehicles. The aim of this overview is to look in depth at a number of areas linked by the recently concluded HYDROGEN research network, representing an intentionally multi-faceted selection with the goal of advancing the field on a number of fronts simultaneously. For the general reader we provide a concise outline of the main approaches to storing hydrogen before moving on to detailed reviews of recent research in the solid chemical storage of hydrogen, and so provide an entry point for the interested reader on these diverse topics. The subjects covered include: the mechanisms of Ti catalysis in alanates; the kinetics of the borohydrides and the resulting limitations; novel transition metal catalysts for use with complex hydrides; less common borohydrides; protic-hydridic stores; metal ammines and novel approaches to nano-confined metal hydrides.

Towards Versatile and Sustainable Hydrogen Production through Electrocatalytic Water Splitting: Electrolyte Engineering

“…One of the promising solutions towards this issue is the electrocatalytic conversion to produce energy carriers. In this context, hydrogen has attracted tremendous attention in this decade4, 5, 6, 7 owing to its extremely high energy density (H 2 : 120 MJ kg −1 and gasoline: 44 MJ kg −1 ) 4, 5…”

Bio-inspired chemical hydrogen storage and discharge as a source of electrical energy

“…The mediator MB was added to the integrated hydrogen storage cell for proton ion and electron storage in stoichiometric quantities. This type of reversible bio-inspired non-biotic hydrogen storage is closely related to the chemical hydrogen storage principle [6][7][8]. In conclusion, bio-inspired chemical hydrogen storage is a bionic variant of the hydrogen storage principle found in all kinds of living cells.…”

Hydrogen Storage Property of the Pd Nanoparticle with Clean Surfaces Studied by QCM

“…The QCM can detect the mass change by the frequency shift of the quartz. The frequency changes not only mass loading but also the gas pressure, viscosity and roughness of the surface [15][16][17][18]. The frequency shift of the quartz crystal in the gas atmosphere (∆f ) is expressed by ∆f = ∆f m + ∆f p + ∆f η + ∆f r + ∆f T…”
