Storage of Renewable Energy by Reduction of CO2 with Hydrogen

Philippe Mauron, Shunsuke Kato, Elsa Callini, Marco Roman Holzer, Jianmei Huang

The main difference between the past energy economy during the industrialization period which was mainly based on mining of fossil fuels, e.g. coal, oil and methane and the future energy economy based on renewable energy is the requirement for storage of t ...

Surface Reactions are Crucial for Energy Storage

Philippe Mauron, Shunsuke Kato, Elsa Callini

Reactions between gas molecules, e.g. H-2 and CO2 and solids take place at the surface. The electronic states and the local geometry of the atomic arrangement determine the energy of the adsorbate, i.e. the initial molecule and the transition state. Here w ...

Description of the capacity degradation mechanism in LaNi5-based alloy electrodes

Philippe Mauron, Mariana Spodaryk, Marco Roman Holzer

The mechanism of the capacity degradation of LaNi5-based alloy electrodes was investigated with a special focus on the influence of the alloy and surface composition, as well as the unique structure obtained by gas atomisation. The electrochemical properti ...

The catalyzed hydrogen sorption mechanism in alkali alanates

Philippe Mauron, Shunsuke Kato, Elsa Callini

The hydrogen sorption pathways of alkali alanates were analyzed and a mechanism for the catalytic hydrogen sorption was developed. Gibbs free energy values of selected intermediate steps were calculated based on experimentally determined thermodynamic data ...

Hydrogen Desorption Kinetics in Metal Intercalated Fullerides

Philippe Mauron

For different hydrogenated metal intercalated fullerides (Na10C60-H, Li12C60-H, and Li28C60-H) the activation energies for hydrogen desorption were determined by DSC. The Vyazovkin advanced method (VA) was used for the calculation of the reaction model fre ...

Hydrogen Dynamics in Nanoconfined Lithiumborohydride

Philippe Mauron

Lithiumborohydride (LiBH4) contains 18.5 wt % hydrogen and exhibits a structural phase transition (orthorhombic→ hexagonal) at 381 K, which is associated with a large increase in hydrogen and lithium mobility in the solid. Confining metal hydrides in a nan ...

Hydrogen Sorption in Li12C60

Philippe Mauron

The lithium-intercalated fulleride Li12C60 was investigated in view of a lightweight hydrogen storage material due to the low molecular weight of its constituents. Deuterium (D2) absorption in Li12C60 shows an uptake of up to 9.5 mass % D2 (equivalent to ∼ ...

Controlling the Dehydrogenation Reaction toward Reversibility of the LiBH4-Ca(BH4)(2) Eutectic System

Philippe Mauron

Controlling the dehydrogenation process in a suitable reaction route by choosing the appropriate reaction conditions is crucial for a hydrogen storage system. The dehydrogenation process of the eutectic 0.68LiBH4-0. 32Ca(BH4)2 mixture was investigated by d ...

Reversible hydrogen absorption in sodium intercalated fullerenes

Philippe Mauron

The hydrogen absorption of sodium intercalated fullerenes (Na xC60) was determined and compared to pure fullerenes (C60). Up to 3.5 mass% hydrogen can reversibly be absorbed in Na xC60 at 200 °C and a hydrogen pressure of 200 bar. The absorbed amount of hy ...

Solvent-free synthesis and decomposition of Y(BH4)(3)

Philippe Mauron, Yan Yan

The direct and solvent-free synthesis of yttrium borohydride was achieved by reactive ball milling of yttrium hydride in diborane/hydrogen atmosphere. The product contains only the solid elemental hydride as remaining contaminant. Yields above 75% were obt ...
