NEWPORT BEACH, Calif. – Clean Energy Fuels Corp. (Nasdaq: CLNE) today introduced ZERO NOW, a fueling solution that combines the world’s cleanest engine technology with the cleanest fuel at a price of $1 per gallon for one year. Heavy duty trucks that are powered by the new ultra clean Cummins Westport (CWI) ISX12N engine purchased this year will be eligible for Clean Energy’s Redeem™ renewable natural gas (RNG) at its California stations for the low price of $1 per gallon for an entire year.

Heavy duty truck fleets are under pressure to meet stricter emissions standards and Clean Energy’s ZERO NOW solution does that – today. The new CWI natural gas engine achieves the lowest emissions levels in North America, yet delivers diesel caliber performance with reliability and durability. The U.S. Environmental Protection Agency and California Air Resources Board certified these engines in December 2017 at CARB’s optional Low NOx standard of 0.02 g/bhp-hr, 90% lower emissions than the current EPA NOx standard. In fact, the new engines were tested at 0.01 g/bhp-hr, achieving virtually zero tailpipe emissions. Clean Energy’s Redeem is made entirely from organic waste and is up to 70% cleaner than diesel, making it the cleanest fuel available in North America.

“By pairing the cleanest fuel available with the cleanest engine technology, ZERO NOW provides heavy duty truck fleets with a true zero-emissions solution that can be easily and economically adopted today,” said Andrew Littlefair, president and CEO of Clean Energy Fuels. “At a time when the price of dirty diesel is bumping up to $3.75 a gallon in California, paying only $1 a gallon for a year for clean Redeem can go a long way to recouping the cost of a new truck. Add in the grants available in California for new clean trucks, the ZERO NOW special offer makes it a no-brainer to switch to renewable natural gas.”

The Redeem Dollar Deal program is available on a first come, first served basis to the first 250 qualifying trucks. These trucks are able to fuel with Redeem RNG at Clean Energy’s extensive network of 23 stations throughout California. Also, Clean Energy has dedicated professionals that will help customers navigate through the application process for grants.
