To realise the goal of high efficiency, low-pollution, sustainable and abundant energy sector, hydrogen will play a significant role in energy storage . Gas composition measurements for H2 energy storage applications mainly consist of detecting gas concentrations such as H2 to evaluate the electrochemical processes as well as their performance. The measurement of one or more gas components and concentrations may serve as important indicators for the state of chemical or thermodynamic processes in energy systems such as mass transport in fuel cells, water electrolysers or concentration batteries. Gas compositions are usually measured by using IR light absorption sensors or Raman scattering sensors and can be combined with optical fibres to confine the molecule detection at a microscale. This chapter presents principles for sensing different gas components, possible types of optical fibre systems solutions for gas detection and challenges and advantages with these.
