Renewable Natural Gas

Renewable Natural Gas (RNG) is pipeline quality gas that is fully interchangeable with fossil natural gas but is produced from a renewable feedstock and can be used as a 100% substitute for, or blended with, conventional natural gas. RNG is an important alternative fuel that can help the State of California meet several Greenhouse Gas (GHG) and renewable energy targets. As a transportation fuel, RNG's carbon intensity is up to 90% less than that of conventional fuels.

About the Center for Renewable Natural Gas

The Center’s goal is to accelerate commercialization of new RNG production and utilization technologies through research, demonstration and optimization in all major sectors, including transportation.

The Center is conducting experimental and modeling work to identify optimal RNG production pathways, scenarios, and associated requirements. The Center is equipped to study all of the major technological areas and partners with multiple stakeholders including utilities, local and federal government agencies, and private industry.

Research Focus

  • Thermochemical RNG production using renewable feedstocks
  • Hydrogen production through water electrolysis using renewable electricity followed by methanation to produce RNG
  • Systems level techno-economic and life cycle analyses to evaluate and optimize technology pathways
  • Resource availability and processing challenges
  • Market and policy analysis
  • Related technologies such as direct hydrogen injection into pipeline, RNG composition for low NOx engines, advanced vehicle technologies to enable increased RNG use in transportation, etc.
