Abstract:
The invention relates to an operating fluid for a steam cycle process apparatus comprising a steam generator, an expander, a condenser and a reservoir for the operating fluid, comprising a working medium that evaporates by supplying heat in the steam generator, performs mechanical work in the vapour phase by expanding in the expander and condenses in the condenser and an ionic liquid which forms a mixture with the working medium, wherein the melting point of the mixture lies below −5° C.
Abstract:
A storage medium for storing hydrogen as well as a process for storing hydrogen are described.According to the invention, the storage medium has an ammonia-borane complex that is present in at least one dehydrogenatable ionic liquid.In this connections the proportion of the ammonia-borane complex to the ionic liquid is between 0.01 and 500, preferably between 0.2 and 10, and in particular between 0.5 and 20.
