Electrolyte-Assisted Hydrogen Storage Reactions

Novel Electrolyte Energy Storage Systems

To enhance reliability of the electric grid while simultaneously incorporating renewable power sources into it, there is a pressing need for electrical energy storage, to increase the capability for dispatch and to accommodate the variable nature of those resources. There is, at present, very little energy storage on the grid, due in part to the high capital costs associated with electrochemica...

Novel Electrolyte Energy Storage Systems

We seek an approach to enable widespread deployment of grid-based storage by drastically lowering the cost of such a system. We are doing so by reexamining the fundamentals of flow battery technology and engaging in an effort in which the active redox couples, the materials that separate the couples, and the flow characteristics that dictate the rate of delivery are optimized, thereby allowing ...

Hydrogen Production and Storage

■ This paper offers an overview of the technologies for hydrogen production. The technologies discussed are reforming of natural gas; gasification of coal and biomass; and the splitting of water by water-electrolysis, photo-electrolysis, photo-biological production and hightemperature decomposition. For all hydrogen production processes, there is a need for significant improvement in plant effi...

Thermodynamic guidelines for the prediction of hydrogen storage reactions and their application to destabilized hydride mixtures

We propose a set of thermodynamic guidelines aimed at facilitating more robust screening of hydrogenstorage reactions. The utility of the guidelines is illustrated by reassessing the validity of reactions recently proposed in the literature and through vetting a list of more than 20 candidate reactions based on destabilized LiBH4 and Ca!BH4"2 borohydrides. Our analysis reveals several reactions...
