The fueling contract begins with a one-year pilot where Clean Energy will provide Redeem to one of Metro’s 11 compressed natural gas stations, which are currently operated and maintained by Clean Energy. Each station 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.

Over the five-year period, the transition to RNG will reduce Metro’s greenhouse gas (GHG) emissions by over 520,000 metric tons over the use of regular natural gas and by almost 900,000 metric tons over the use of diesel. Unrelated to the use of Redeem, Metro will begin retrofitting and replacing their buses with the new Cummins-Westport Low NO_x CNG engines that reduce smog-forming NOx and GHG emissions that are 90% lower than the EPA NO_x limit.

Redeem is derived from biogenic methane or biogas, which is methane that is naturally generated by the decomposition of organic waste. The methane gas is then processed, purified and sent into the interstate natural gas pipeline and transported to Clean Energy’s and its customers’ stations.
