Materials with desirable Thermodynamics Properties for the Storage of Hydrogen Energy using Sponge Metals

Research output: Contribution to conferencePaper

Abstract

Hydrogen is the fuel that can be most readily generated from renewable power, but the compact, safe and energy-efficient storage of this gas is an issue. A potentially advantageous scheme that could meet the above requirements consists in reacting the hydrogen with a metal oxide (reduction) to produce very porous metal. Iron is usually considered due to its low cost and low toxicity. However the amount that reacts is limited by thermodynamic equilibrium, which requires potentially uneconomical recovery, recompressing and recycling of the unreacted hydrogen. It has been proposed to use alloys instead to circumvent this problem. This paper outlines ongoing modelling and experimental work that seeks to explore, predict and validate the thermodynamics properties alloys and their corresponding mixed oxides, in order to find a suitable system.
