SoCalGas Among First in the Nation to Test Hydrogen Blending in Real-World Infrastructure and Appliances in Closed Loop System

Preliminary results of testing that began earlier this summer show the household natural gas appliances are compatible with up to a 20% hydrogen blend. These initial findings are consistent with previous international research and lab testing. This effort provides key operational and safety experience, including testing for pipeline leaks, that will enable SoCalGas to implement larger scale hydrogen blending demonstrations.  SoCalGas continues to test the impacts of blending hydrogen with natural gas on pipelines and appliances.
