Thermodynamic analysis of hydrogen pipeline transportation – selected aspects

Nowadays we can observe an increasing seek for a new alternatives for the sources and devices of energy storage. One of those sources is hydrogen which can be used in process of energy storage (analogous for compressed air). Hydrogen energy storage facility (in most cases – salt caverns) is often located at long distance from hydrogen source. Due to high amount of hydrogen to be transported transport by tank trucks must be rejected because of its low efficiency. The optimal way of hydrogen transport is pipeline transportation. Hydrogen can be transported by pipeline as a pure fluid or as a component in natural gas mixture. The main target of this paper is the thermodynamic analysis of hydrogen pipeline transportation as a pure fluid or as component of natural gas. Provided analysis includes pressure drop and temperature changes for different assumed cases of hydrogen pipeline transport.
