Control valve selection for blue hydrogen production

6/30/2026

S. GRILLS and A. PRUSHA, Emerson, Marshalltown, Iowa (U.S.) Hydrogen (H2) demand is quickly increasing because the gas plays a growing role in the world’s energy decarbonization strategy. H2 provides a clean energy source for industrial processes, is finding use in the transportation sector and can be used for long-term storage of electrical energy. Unfortunately, elemental H2 is quite rare, so it must be produced via industrial processes. Most of the H2 produced today is used in the refining and chemical markets and is created by a process called steam methane reforming (SMR). As green energy and sustainability initiatives come into operation, H2 production must expand dramatically; ho
