Hydrogen Storage in the Expanded Pore Metal-Organic Frameworks M-2(dobpdc) (M = Mg, Mn, Fe, Co, Ni, Zn)

Wendy Lee Queen, Miguel Gonzalez

The hydrogen storage properties of a new family of isostructural metal organic frameworks are reported. The frameworks M-2(dobpdc) (M = Mg, Mn, Fe, Co, Ni, Zn; dobpdc(4-) = 4,4'-dioxidobiphenyl-3,3'-dicarboxylate) are analogous to the widely studied M-2(do ...

Stabilization of volatile Ti(BH4)(3) by nano-confinement in a metal-organic framework

Elsa Callini

Liquid complex hydrides are a new class of hydrogen storage materials with several advantages over solid hydrides, e.g. they are flexible in shape, they are a flowing fluid and their convective properties facilitate heat transport. The physical and chemica ...

Storing Renewable Energy in the Hydrogen Cycle

Shunsuke Kato, Elsa Callini

An energy economy based on renewable energy requires massive energy storage, approx. half of the annual energy consumption. Therefore, the production of a synthetic energy carrier, e.g. hydrogen, is necessary. The hydrogen cycle, i.e. production of hydroge ...

Redox flow battery and indirect water electrolysis

Véronique Amstutz

The progressive integration of renewable energy sources such as wind turbines and photovoltaic pannels in the current electrical network, and the rise of the electrical mobility, provoke a change of paradigm in the sector of energy management. The increasi ...

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 ...

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 ...

Closing the pressure gap in x-ray photoelectron spectroscopy by membrane hydrogenation

Comprehensive studies of gas-solid reactions require the in-situ interaction of the gas at a pressure beyond the operating pressure of ultrahigh vacuum (UHV) X-ray photoelectron spectroscopy (XPS). The recent progress of near ambient pressure XPS allows to ...

Study of hydrogen storage and compression

Nicolas Jean Matet

The goal of this rapport is to present an overview of the different hydrogen storage technologies, currently available for industrial application or at earlier stages of development. In order to identify the water and mechanical work requirements for compr ...

Direct Carbon Dioxide Hydrogenation into Formic Acid in Acidic Media

Séverine Joëlle Moret

A major challenge in the face of increasing global energy demand is the development of alternative environmentally friendly and renewable energy resources. Hydrogen is an excellent energy carrier, but has drawbacks in storage density and is dangerous to ha ...

Homogeneous Catalytic Dehydrogenation of Formic Acid: Progress Towards a Hydrogen-Based Economy

Paul Joseph Dyson, Gabor Laurenczy

One of the limiting factors to a hydrogen-based economy is associated with the problems storing hydrogen. Many different approaches are under evaluation and the optimum approach will not be the same for all applications, i.e., static, mobile, small and lar ...
