Renewable Natural Gas Research Center Project

Principal Investigator: Arun Raju | University of California, Riverside
Research Team: Partho Sarothi Roy | University of California, Riverside

Renewable Natural Gas (RNG) is an important alternative fuel that can help the State of California meet several GHG and renewable energy targets. Despite considerable potential, current RNG use on national and state levels are not significant. As part of this grant, the University of California, Riverside (UCR) has established a research center dedicated to the development of technologies that will enable RNG production and use in substantial quantities in California and elsewhere. The new center, referred to as the Center for Renewable Natural Gas, leverages on-going research and collaborations at the Bourns College of Engineering – Center for Environmental Research & Technology at UCR to maximize the impact.

RNG production potential in California through thermochemical conversion was evaluated as part of this project by assessing technical biomass availability in the state. Oxygen/air blown gasification, hydrogasification and pyrolysis are the three major technology options available for thermochemical biomass conversion to a gaseous fuel, including RNG. A literature survey of available thermochemical conversion technologies was conducted. Although there are no commercial thermochemical biomass to RNG conversion facilities in operation, a number of gasification and pyrolysis technologies are undergoing pilot scale demonstration and development. Design basis for two thermochemical and power to gas conversion projects were developed as part of this project. Significant research, development, and deployment efforts are necessary to achieve successful commercialization of thermochemical RNG production. Outreach and education activities, including a ribbon cutting ceremony for the Center for Renewable Natural Gas and an RNG themed symposium, were also conducted as part of the project.
