T1 - Explosion protection for mixtures of hydrogen and natural gas T2 - Proceedings of the 21st World Hydrogen Energy Conference 2016 N2 - Safety characteristics for explosion protection for mixtures of hydrogen and natural gas were studied in laboratory tests. Also calculations on the explosion zones for mixtures of hydrogen and natural gas were conducted. Moreover calculation methods for the safety characteristics of such mixtures were tested aiming to reduce the high effort for the experimental determination of safety characteristics prospectively. Admixture of up to 10 mole% hydrogen to natural gas has very low influence on safety characteristics for explosion protection. With increasing hydrogen fraction the mixtures become mainly more „critical“ considering explosion protection, an substantial influence on explosion protection occurs for hydrogen fractions of more than 25 mole%.
