Abstract

The HIRSA programme is assessing ignition risks for the transition to hydrogen, with Stage 3 focusing on high pressure static risks including shockwave ignition and rapid adiabatic compression. This research supports the safe integration of hydrogen into gas networks.

This project will address a key evidence gap concerning the impact on ignition risk when considering a change of gas in the network. The risk implications of transitioning from Natural Gas to hydrogen are not clearly understood where high pressure mechanisms like shockwave ignition and rapid adiabatic compression are concerned. This project will develop empirical evidence and in turn develop recommendations for mitigation measures if they are deemed to be necessary in the transition to a 100% hydrogen and/or blended gas network.
