Hydrogen compatibility assessment in natural gas infrastructures

Abstract

Man's progress during the years of his existence on Earth is remarkable. From the discovery of fire until today, technology is constantly developing and so are the needs of man. From the industrial revolution (1750-1840) onwards and especially from the beginning of the first world war (1914-1918), industry developed rapidly, and of course the extraction and use of hydrocarbons. The first fuels were coal and oil, while now we refer to fuels such as natural gas, ammonia and hydrogen. Now beyond the capacity of our global energy needs, where it is a matter of resolution, the use of milder forms of energy is intensified, according of course to the laws and directives of global organizations and states. Natural gas is a milder fuel compared to other hydrocarbons and is a transition fuel towards greener forms of energy. A green form of energy, subject to conditions in the way it is produced, is hydrogen (green). Hydrogen being a fuel with potential (production, lots of storage, quality of combustion products, etc.) and energy content, it is considered one of the fuels of the future. For this reason, it has generated a lot of interest in the energy field, on how we can exploit its reaction with oxygen (O2) and produce large amounts of energy, store it, produce it with zero pollutants, and transport it. In this work, reference is made to the issues that arise during the blending of hydrogen into natural gas pipelines, as it constitutes a wide network, ready for use.
