Clean Energy, Mansfield partner for CNG fueling services
Sales teams from both companies will offer Clean Energy’s natural gas fueling station construction and operational services to current and potential customers. Officials say these services will be supported by Mansfield’s large-scale fuel supply capabilities and Gas-2-Gallons fuel management system.
Clean Energy Fuels Corp. and Mansfield Energy Corp. recently partnered to offer customers a comprehensive solution in the compressed natural gas (CNG) fuel industry.
Sales teams from both companies will offer Clean Energy’s natural gas fueling station construction and operational services to current and potential customers. Officials said these services will be supported by Mansfield’s large-scale fuel supply capabilities and Gas-2-Gallons fuel management system.
“This agreement joins two leaders of fleet fueling into strategic partners that will provide the highest level of service and best value for customers in the rapidly growing natural gas fuel market,” said Andrew J. Littlefair, president and CEO of Clean Energy.
“We want our customers to have the best solution possible for fueling with natural gas,” said Michael Mansfield, CEO of Mansfield. “We bring scale in commodity supply, risk management and transaction processing. Clean Energy has scale in design, engineering and operations. Bringing these strengths together for our customers provides the benefits of proven technology coupled with large-scale operating efficiencies to provide the best value and simplest path to natural gas adoption in the market today.”
Mansfield Gas Equipment Systems has ongoing CNG service and operations contracts with 43 locations as well as 20 new CNG sites currently under development in the waste, transit and municipal fleet sectors.
This portfolio will be combined with the 348 CNG and liquefied natural gas fueling stations Clean Energy currently owns, operates or supplies. Clean Energy’s total strategic partnerships to date represent over 11 billion gallons of gasoline and diesel delivered annually, officials said.
The company also will become the western distributor of Mansfield Gas Equipment Systems’ FuelMaker, a small-scale business and home refueling system.
