U.S. natgas companies put hydrogen to the test

At least two dozen U.S. energy firms, including Dominion Energy Inc (D.N) and Sempra Energy (SRE.N), have started producing hydrogen or testing its viability in natural gas pipes to take advantage of existing infrastructure as the world prioritizes lower-carbon fuels.

Nations worldwide are trying to reach net-zero carbon emissions by 2050, but that will rely heavily on technology - like hydrogen - that is in developmental stages. Utilities have a potential advantage if they find that clean-burning hydrogen can be successfully transported in existing gas pipes and power plants.
