California agencies award grants six in-state dairy to RNG pilot projects

The California Public Utilities Commission (CPUC), the California Air Resources Board (CARB), and the California Department of Food and Agriculture (CDFA) today announced funding for six pilot projects in the San Joaquin and Sacramento Valleys designed to demonstrate the collection of biomethane from dairy digesters and its injection into natural gas pipelines. The production of biomethane from organic waste products, including animal manure, eliminates significant emissions of methane to the atmosphere. 

Future of Renewable Fuel Standard Debated at House Hearing

A bill that would require new cars to operate using more efficient gasoline and sunset the Renewable Fuel Standard drew praise and criticism at a House Subcommittee on Environment hearing.

The 21st Century Transportation Fuels Act (section-by-section summary here) requires manufacturers of light-duty vehicles model years 2023 and later to design motor vehicles to operate using gasoline with research octane number (RON) of 95 or higher and improve fuel economy connected to the use of 95 RON or higher level gasoline.

RNG Coalition's Manning Feraci Testifies at U.S. House Hearing on future of RFS

On Tuesday, the House Energy and Commerce Committee’s Subcommittee on the Environment convened a hearing on the 21st Century Transportation Fuels Act, a discussion draft led by U.S. Reps. John Shimkus, R-Ill., and Bill Flores, R-Texas, to reshape federal transportation fuel policies.

Notably, the hearing discussed the future of the Renewable Fuel Standard (RFS) program. 

“Since the RFS was first established in 2005 and expanded in 2007, much has changed in the market for transportation fuels. If federal policies are not routinely evaluated and updated to reflect market conditions, consumers end up having less than optimal choices,” said Flores.

Hawaii Commissions its First RNG Production Location at Hono'uli'uli Wastewater Facility

A first of its kind renewable gas facility opened on O'ahu Wednesday.

The plant is connected to the City's Hono'uli'uli Wastewater Treatment facility and is managed by Hawaii Gas. The purpose is to turn sewage into energy and hopefully eliminate the need for nearly 15,000 barrels of oil per year. "Today is a huge milestone because we want to do more renewable natural gas," CEO of Hawai'i Gas Alicia Moy said.

Three CalBio Dairy Pilot Project Clusters Selected for Development

On Monday, December 3, members from the California Public Utilities Commission (CPUC), the California Air Resources Board (CARB), and the California Department of Food and Agriculture (CDFA) announced that California Bioenergy LLC (CalBio) was awarded funding for 3 Dairy Pilot Projects selected to install dairy digester renewable fuel technology. The announcement is available at

The dairy bio-methane pilot program is part of the state’s strategy to reduce emissions of short-lived climate pollutants, including methane, which is 28 times more potent than carbon dioxide. Legislation adopted in 2016 requires the state to reduce methane emissions from the dairy and other livestock sectors by 40 percent by 2030. Emissions from dairy manure account for approximately 25 percent of the State’s overall methane emissions. The inter-agency committee that selected the projects consisted of representatives from the CPUC, CARB, and CDFA.
