Norfolk Southern, one of the US's largest transporters of coal and industrial products, has primarily been using a 100 per cent pure Dynamic Fuels renewable diesel at its Meridian, Mississippi rail yard since early January.

Dynamic Fuels, recently signed commercial off-take and strategic alliance agreements with Mansfield to market renewable diesel to fleet customers.

Dynamic Fuels, operator of the first commercial advanced biofuels plant in the United States, produces next-generation renewable and synthetic fuels from animal fats and greases. The company's Geismar plant produces renewable diesel as "drop in" fuel that can replace 100% of petroleum diesel in a diesel engine without engine modification.

"Norfolk Southern is pleased to be the first fleet user of renewable diesel in the United States," said Gerhard Thelen, Norfolk Southern vice president operations planning and support.

"Our locomotive engines are completely compatible with the pure renewable diesel provided by Dynamic Fuels and Mansfield. Together, they have provided seamless integration of renewable diesel supply into our Meridian, Mississippi, yard. Norfolk Southern has been at the forefront of the railroad industry in evaluating synthetic and renewable diesel fuels for many years. This effort exemplifies Norfolk Southern's commitment to reducing carbon and other emissions, while further integrating sustainability throughout the operations of the company."

"The contract with Norfolk Southern is the first manifestation of Dynamic Fuels' partnership with Mansfield," said Ron Stinebaugh, senior vice president of Syntroleum Corporation.

"We look forward to working with Norfolk Southern to lower their emissions and increase the renewable content of the fuel they burn. Renewable diesel is a sustainable, ultra clean burning, high cetane fuel that reduces carbon emissions and significantly reduces particulates and NOx when combusted in existing diesel engines. Supplying a prestigious company like Norfolk Southern validates our belief that customers are looking for renewable options that increase sustainability and lower emissions without sacrificing fuel quality."

Doug Haugh, president of Mansfield Oil Company added: "Mansfield and Norfolk Southern have had a strong relationship on the refined products side and we're excited to supply them with a next-generation fuel like renewable diesel. We believe Dynamic Fuels is a leader in renewable diesel production and our partnership affords us the opportunity to further diversify our portfolio of transportation fuels for our customers."
