Safety challenges in view of the upcoming hydrogen economy: An overview

If produced and arranged in the right way with carbon dioxide as a possible but permanently removed by-product, hydrogen as a new, large scale, applicable energy carrier promises significant reductions of carbon dioxide emissions. It is light, non-toxic, and clean burning. In different parts of the world, viz. United States, Japan, and Europe, programs have started some years ago to investigate hazardous properties of hydrogen in more detail and to develop special safety measures where necessary. Recently, in September 2009, the third International Conference on Hydrogen Safety (3rd ICHS) was held at Corsica, France. CFD tools have been adapted to describe hydrogen dispersion and explosion. Field tests have been carried out, an incident databank has been founded, knowledge gaps were defined, and risk analysis methods reviewed. The latter are required for drafting installation guidelines and measures for safe distances in land-use planning and licensing of hydrogen storage locations, pipelines, and re-fuelling stations. Yet some challenges remain. The paper will summarize present results and will address hydrogen related issues where more knowledge is needed to reduce uncertainty and improve the quality of risk control.
