International Energy Agency, Task 32 “Hydrogen-based Energy Storage”. Hydrogen storage in porous materials, metal and complex hydrides. Applications of metal hydrides for MH compression, thermal and electrochemical storage. Hydrogen energy systems using metal hydrides.
The following areas are covered; porous materials, liquid hydrogen carriers, complex hydrides, intermetallic hydrides, electrochemical storage of energy, thermal energy storage, hydrogen energy systems and an outlook is presented for future prospects and research on hydrogen-based energy storage. 1. Introduction
We summarize the electrochemical hydrogen storage capabilities of alloys and metal compounds, carbonaceous materials, metal oxides, mixed metal oxides, metal–organic frameworks, MXenes, and polymer-based materials. It was observed that mixed metal oxides exhibit superior discharge capacity and cycling stability.
Many kinds of hydrogen storage materials have been studied. Ammonia has a high gravimetric hydrogen density of 17.8 wt%. The theoretical hydrogen conversion efficiency is about 90%. Ammonia is burnable and has advantages as hydrogen and energy carriers. Hydrogen storage technology is essentially necessary to promote renewable energy.
2.2.1. Hydrogen sorption The development of highly efficient hydrogen storage materials is a major challenge in the hydrogen economy. Solid-state hydrogen storage can either be done through physisorption in porous materials or chemisorption in hydrides.
The task consists of seven working groups, working on porous materials, intermetallic alloys and magnesium-based hydrides as energy storage materials, complex and liquid hydrides, electrochemical storage of energy, heat storage and hydrogen storage systems for stationary and mobile applications.
