Deere Bullish on Biodiesel, Renewable Diesel
by Ryan Ghem (SAE International) … Biodiesel and renewable diesel will lead the way for alternative-fuel integration into the heavy equipment industry, according to Nick Block, director of worldwide marketing, sales & customer support, John Deere Power Systems (JDPS).
“We support the use of biodiesel and renewable diesel because we recognize the importance of biofuels to our customers and to the environment,” he said, in response to some questions from SAE International regarding the engine manufacturer’s alternative-propulsion priorities.
Which alternative fuels have the most potential in heavy-duty equipment?
We believe biodiesel and renewable diesel to be the most viable alternatives to diesel fuel for heavy-duty off-highway engines. John Deere engines operate efficiently using ultra-low sulfur diesel as well as biodiesel blends. It’s the right thing to do from a long-term economic standpoint, as well as environmental, energy-security and rural-development standpoints.
The primary advantages of both biodiesel and renewable diesel are their renewability. As renewable energy sources, they can help reduce dependence on petroleum imports. Biodiesel (B100) is nontoxic, biodegradable and suitable for sensitive environments.
Any other significant benefits?
The use of biodiesel and renewable diesel fuel results in improved lubricity, zero aromatics and minimal sulfur. It has a very favorable energy balance – the difference between the energy produced by one kilogram of fuel and the energy necessary to produce it – of 3.2 to 1. This means a gallon of biodiesel provides users with 3.2 times the energy it takes to produce it, which is a higher ratio than most alternative fuels.
Which emissions or other regulations are you monitoring?
We anticipate that the additional NOx reduction standards that are being considered for on-highway will eventually make their way to off-highway regulations. This will impact the industry as manufacturers continue to keep track of nuanced regulations from country to country, while helping their customers manage necessary transitions. READ MORE
