Storage of liquid hydrogen in natural zeolite

Abstract

When producing and utilizing hydrogen, its storage is one of the biggest problems. Hydrogen, as a gas, is extremely fluid with very low specific weight. Moreover, at a certain rate, the hydrogen-oxygen mixture is explosive. Therefore, the storage of hydrogen is relatively dangerous. A storage of liquid hydrogen in the natural zeolite, which is placed in large capacity battery, appears to be a suitable hydrogen storage method. Proposed and constructed pressure tank, large capacity battery, allows long-term and safe storage of liquid hydrogen, with the possibility to change its state from liquid to gaseous or contrarily in real time. Natural zeolite is an inert material with large internal surface area and high thermal capacity. In the future, presented large capacity battery VAZEP can be a part of the system for production and storage of electric energy generated by photovoltaic modules from the sun.
