Contract Kicks Off with a One-Year Pilot,
Could Lead to RNG Supply for 2,200 Buses
With Estimated Annual Use of 38 Million GGEs
Clean Energy Fuels has an agreement with the Los Angeles County Metropolitan Transportation Authority to provide its Redeem brand RNG/renewable natural gas for the LA Metro fleet of CNG/compressed natural gas transit buses.
The pact is for a one-year pilot program for Clean Energy to supply Redeem brand biomethane to one of LA Metro’s eleven CNG stations (currently operated and maintained by Clean Energy). Each provides fuel for approximately 200 CNG buses.
“Execution of an additional option will allow Clean Energy to provide Redeem to the entire fleet of 2,200 natural gas buses for four more years, for an anticipated 38 million gasoline gallon equivalents (GGEs) each year,” the provider says.
Better than Conventional CNG, Far Better than Diesel
Over the five year period, Clean Energy says, the transition to RNG will reduce LA Metro’s GHG/greenhouse gas (GHG) emissions by more than 520,000 metric tons over the use of conventional natural gas and by almost 900,000 metric tons over the use of diesel.
Low-NOx Cummins Westport Engines Too
Separately LA Metro is to begin retrofitting and replacing its buses with new super low-NOx Cummins Westport engines.
LA Metro was the first to get New Flyer buses with the 8.9-liter ISL G Near Zero engine (F&F, August 17, 2016).
Cummins Westport said at ACT Expo 2017 early this month that, under an initiative dubbed “Move to Zero,” it would rename that engine the L9N for 2018, and offer super low-NOx variants of its 6.7- and 11.9-liter natural gas engines as well, to be released as the B6.7N and the ISX12N (formerly the ISX12 G; F&F, May 5).
“As one of the largest transit agencies in the nation, we take our responsibility to the environment and the taxpayers very seriously,” LA Metro executive officer for environment and sustainability Cris Liban says in the Clean Energy announcement.
“The use of RNG allows us to further exceed our environmental goals and reduce our reliance on the use of extracted fossil fuels, while ensuring the seamless transition to a cleaner, greener fleet,” he said.
“We are continuously assessing new technologies in transportation and perform a rigorous analysis before adopting anything,” said agency vehicle technology director John Drayton.
“In this case, transitioning to renewable natural gas along with the use of low NOx engines reduces our fleet’s NOx emissions by 90%,” he said.
“It was an easy decision.”
“Metro is putting the needs of its customers and the people of Los Angeles County at the forefront in its decision to switch to Redeem and the latest clean engine technology,” said Clean Energy Renewables VP and general manager Tyler Henn.
LA Metro, he said, has “chosen an alternative that will make significant strides in cleaning up the air and reducing harmful air toxins and greenhouse gases at an affordable price.”
