T1 - Power-to-Gas: Safety characteristics of hydrogen/natural-gas-mixtures N2 - LEL, UEL LOC, MESG, pmax and (dp/dt)max of hydrogen/natural gas-mixtures were determined systematically according to international standards. Mixtures of natural gas and hydrogen mainly become more „critical“ with increasing hydrogen fraction. The effect of up to 10 Vol% H2–admixture to natural gas on safety characteristics is very low, no major adaption of existing measures for explosion protection is necessary. More substantial adjustment of measures for explosion protection is necessary at hydrogen fractions of more than 25 Vol%. Some of the safety characteristics can be estimated with good accuracy by calculation methods.
