Southern California Gas Co. (SoCalGas) is advancing its bet on renewable natural gas (RNG) and hydrogen as energy transition tools with new technology that could turn Los Angeles refuse into carbon-negative fuel.

The combination utility has partnered with energy startup Kore Infrastructure to create a commercial scale version of Kore’s waste processing technology at a SoCalGas facility in central Los Angeles. With operations underway, Kore and its backers are demonstrating how its process could create carbon-negative hydrogen or RNG by using landfill waste that would potentially release greenhouse gas into the atmosphere as it decomposes.

“The production of carbon-negative RNG and hydrogen could help provide energy security and decarbonize California in our energy...
