US freight carrier adds 50 Clean Energy RNG trucks to fleet

Estes Express Lines, a major freight transportation carrier based in Virginia, US, will add 50 new trucks fuelled by Clean Energy Fuels’ Redeem™ renewable natural gas (RNG) to its fleet.

Estes is acquiring the Class 8 natural gas trucks equipped with the Cummins Westport ultra-clean ISX12N engine for its California fleet and is expected to use around 2.8 million gallons of RNG over the seven-year contract.

Clean Energy’s Redeem was the first commercially available RNG vehicle fuel, derived from capturing the biogenic methane produced by the decomposition of organic waste from dairies, landfills, and wastewater treatment plants. According to the firm, Redeem reduces greenhouse gases by at least 70% and even up to 300%, depending on the source of the RNG.

Estes bought the trucks through Clean Energy’s Zero Now programme, which brings the price of a natural gas truck at parity with a diesel truck while offering a guaranteed fuel discount.

Rob Estes, CEO of Estes, said: “Switching to trucks fuelled with ultra-low carbon fuel is vital to improving air quality and fighting climate change in the regions that we serve.

“Clean Energy’s Zero Now programme has enabled us to switch to cleaner fuel and engine technologies that make financial sense – so it’s a win on several levels.”

“By adding 50 clean, sustainable, natural gas trucks to its fleet Estes demonstrates its leadership in the drive to lower the carbon footprint by the heavy-duty trucking industry,” said Brett Lindsay, vice-president of Clean Energy.

“With the support of our Zero Now programme, Estes has been able to easily and quickly switch a growing number of its trucks to RNG, significantly decreasing the environmental impact of its operations.”
