Clean Energy Fuels Corp. announced it has signed a fueling agreement with Mountain Valley Express (MVE), an express shipping company based out of Manteca, California, that has purchased nine heavy-duty trucks equipped with the new CWI 9L ISL G Zero NOx natural gas engine. The fueling agreement will allow Mountain Valley to use Clean Energy’s Redeem™ brand of renewable natural gas (RNG) vehicle fuel for the new trucks. These revolutionary engines reduce smog-forming NOx emissions by 90% over the current U.S. Environmental Protection Agency (EPA) standard, and when combined with Redeem™, have 70% less greenhouse gas (GHG) emissions than diesel trucks.


“At Mountain Valley Express, our motto is “Go Green,” and I can think of no better way to demonstrate our commitment to the environment and reducing our footprint than by having these trucks use Redeem™,” said James Scott Blevins, President and CEO of MVE.


With a NOx emissions level of 0.02 g/bhp-hr, the California Air Resources Board (CARB) has defined this zero emissions level as equivalent to a 100% battery truck using electricity from a modern combined cycle natural gas power plant. Beginning in 2018, CWI will begin producing a 12-liter version of the engine.


“Thanks to technological advancements and the use of renewable natural gas, the transportation industry has come a long way in reducing the amount of NOx and GHGs that are emitted,” said Andrew J. Littlefair, President and CEO of Clean Energy. “Mountain Valley Express is showing great leadership by being one of the first trucking companies to convert to the new zero-equivalent engine and Redeem™ renewable natural gas, and is truly living up to their motto of “Go Green.”


In addition to new fuel agreements, Clean Energy has been contracted to construct multiple fueling stations in early 2017.
