Sempra Has to Turn to Cow Dung to Make Up for California Gas Leak

Reparations for the worst-ever U.S. natural gas leak will involve cow-dung duty. That’s the takeaway from Sempra Energy’s $119.5 million settlement with Los Angeles and California agencies over the leak almost three years ago at the Aliso Canyon gas storage facility owned by the company’s Southern California Gas utility. Almost a quarter of the money will go to fund a program to capture methane from dairy farms that can be processed into something called renewable natural gas. This RNG can be substituted molecule for molecule for the fossil fuel version and injected into the vast U.S. pipeline network.
