“We continue to work with SoCalGas on transforming several parts of its gas system for introducing some percentage of hydrogen initially and transforming it for eventually carrying all hydrogen,” said Jack Brouwer, UCI engineering professor and hydrogen [National] Fuel Cell Research [Center] director. UCI’s work with Sempra’s SoCalGas utility involves determining what impacts hydrogen-natural gas blends would have on various gas-fired appliances and end-uses. “We’ve found these appliances can handle blends of up to 30% hydrogen with no problem, and in most cases with reduction of nitrogen oxide (NOx) emissions,” Brouwer said.
