Clean Energy Fuels Corp. has signed a fuel supply agreement to provide renewable natural gas (RNG) to the nation’s largest public transit bus fleet at the Los Angeles County Metropolitan Transportation Authority (LA Metro).
The Newport Beach, CA-based operator agreed to provide an estimated 47.5 million gallons of RNG for the 2,400-bus fleet as part of a contract that runs through 3Q2022.
LA Metro’s chief sustainability officer Cris Liban said the transit operator’s use of RNG, in combination with ultra low-nitrogen oxide (NOx) engines, would help it become a net zero-emissions agency by 2050.
The supplies are to come from a nationwide network of RNG suppliers. More recently, Clean Energy opened a fueling station in Whittier, CA, for the Los Angeles County Sanitation District.
Meanwhile, Orlando, FL, is participating in a demonstration program of adsorbed natural gas (ANG) using technology developed by Ingevity Corp.
Orlando plans to add two ANG-equipped Ford F-150 pickup trucks to its fleet to assess data related to fuel savings and emissions reductions. ANG technology reduces the onboard storage pressure of natural gas, enabling a fueling solution for the light-duty market segment.
In other news, Southern California Gas Co. (SoCalGas) has donated $1.3 million to support four hydrogen fuel technologies that could allow emissions-free railways and ports in California.
The Sempra Energy gas-only utility aims to help bring the technologies to market for fuel cell applications in marine vessels, refueling and locomotives. The California Energy Commission (CEC) selected the technologies as part of its hydrogen fuel cell demonstration program.
SoCalGas also is partnering with the Gas Technology Institute, Golden Gate Zero Emission Marine Inc., and clean transportation advocate CALSTART. SoCalGas has separate field test and demonstration programs to clear the way for commercial-scale blending of hydrogen into its gas distribution system.
In addition, the CEC has a $44.1 million research effort underway to support large-scale deployments of on-road, zero-emission Class 8 drayage and regional haul trucks, and zero-emission vehicle fueling infrastructure. Natural gas, electric and other alternative fuel technologies are eligible for the effort; CEC closed the bidding process in early February.
Elsewhere, C-Zero Inc., backed by the Department of Energy, is working to bridge the gap between existing natural gas infrastructure and a low-carbon future that includes hydrogen. C-Zero has won federal grants for pilot hydrogen and fuel cell projects with Pacific Gas and Electric Co. and SoCalGas.
