Safety of Hydrogen & Natural Gas Blends - Research

Safe handling of hydrogen and hydrogen natural gas blends requires an understanding of hazards and associated risks arising from leaks. These include (but are not limited to) hazard distances defined by the extent of the flammable cloud, and thermal effects from jet fire. The impact of leak conditions on dispersion must be understood for typical connections. Understanding of the underlying physical phenomena is key as countries move towards a network with hydrogen blends. Work is needed to adjust safety zones to account for hydrogen blends.
