Using hydrogen in existing domestic natural gas heating systems without additional control measures presents an increased risk of explosions. For instance, kitchen and whole downstairs explosions would become over four times more likely when using hydrogen as a heating gas. This is directly related to the ignition potential of natural gas and hydrogen. These conclusions were based on a quantitative risk assessment study, which analyzed 62 incidents in Great Britain between April 2016 and March 2020.
Predicted number of annual explosions due to natural gas and hydrogen heating systems in residential buildings in Great Britain as of 2021, by event type*
* Ignition probabilities found through quantitative risk assessment study evaluating the ignition potential of hydrogen-air mixtures via household electrical items and a comparison with the ignition potential of methane-air mixtures.
Forecast based on a study of 62 incidents reported between April 2016 and March 2020.
