Southern California Gas Company (SOCALGAS) uses renewable natural gas (RNG) and hydrogen to convert energy transfer equipment into a carbon-negative fuel with new technology Los Angeles Refuse.
The combined utility has partnered with energy startup Core Infrastructure to create a commercial-scale version of Core’s waste processing technology at its SoCalGas facility in Central Los Angeles. In the process, Corey and his supporters are showing how to use landfill waste to create carbon-negative hydrogen, or RNG, which can release greenhouse gases into the atmosphere when it decomposes.
“Carbon-negative RNG and hydrogen production will help provide energy security and decarbonize California’s energy transition,” said Neal Naveen of Socalgas, vice president of Clean Energy Innovations.
El Segundo, CA-based Core has developed a modular system to heat organic waste in a vacuum, turning it into gases and carbon dioxide, without releasing excess emissions into the air.
Similar to methane capture methods used to produce RNG from agricultural waste, the gases produced in the process can be refined into a natural gas alternative and converted into hydrogen.

According to the company, Core is targeting the technology to produce hydrogen to power vehicle fleets, especially for heavy industries. The demonstration facility at the SoCalGas complex is designed to process up to 24 tons of waste per day into 1 metric ton of what the company describes as green hydrogen. Core estimates it can produce enough hydrogen for more than 1,400 fuel cell electric cars.
Commonly referred to as green hydrogen, water is split with electricity in a process called electrolysis, eliminating greenhouse gas emissions from the process. Green hydrogen can reduce the emissions of GHG fuels that are mixed with renewable electricity.
“In California, transportation accounts for approximately 40 percent of greenhouse gas emissions,” said Corel CEO Cornelius Shields. We’re partnering with leaders in the waste, energy and transportation sectors to provide carbon-negative energy solutions made in America.

The project will control air emissions in parts of Southern California thanks to a $1.5 million grant from SoCalGas and additional funding from the South Coast Air Quality Management District. The Core process is designed to meet the Air District’s nitrous oxide and particulate emission standards.
SoCalGas has previously set a goal of providing 20% natural gas to RNG by 2030. In 2021, 4% of the supply is reported to be RNG. California regulators in February proposed a requirement for all utilities in the state to purchase 12% distributed gas. From RNG in 2030.
