Diesel technology continues to be an important part of future mobility planning. Hear from thought leaders across industry, government and education on the progress and role that diesel plays now and will continue to play in the future.
“A Biden-Harris Administration will promote and advance renewable energy, ethanol, and other biofuels to help rural America and our nation’s farmers, and will honor the critical role the renewable fuel industry plays in supporting the rural economy and the leadership role American agriculture will play in our fight against climate change.”
There will be a need for heavy-duty engines in trucking, shipping and air transport well into the future. “Low-carbon fuels like biodiesel, renewable diesel and sustainable aviation fuel are reducing transportation carbon emissions today―a valuable step to achieving climate goals down the road. For example, nearly a quarter of California’s diesel pool today is made up of low-carbon biodiesel and renewable diesel. California’s Low Carbon Fuel Standard program cut 14.6 million tons of carbon in 2019, with biodiesel and renewable diesel use in existing engines and infrastructure accounting for 45 percent of the cuts. Policymakers need to pay attention to what’s working today.”
While Mack’s Walsh doesn’t see diesel suddenly disappearing, the OEM is “excited about the potential for further innovations making diesel even cleaner and more efficient than it is today.”
“These results show that the opposed-piston technology is able to meet our sustainable transportation goals, reducing criteria pollutants while also emitting less carbon dioxide. At a time when the industry is contemplating many technology options to address clean energy, it’s important to have pragmatic solutions in the conversation that can have more immediate impact, and meeting or beating the most stringent regulations with less cost and complexity and no reliance on enabling infrastructure is compelling."
“What’s the future of diesel?” While the role of diesel power moving forward will continue to evolve, we believe it has a long life ahead for off-highway. Diesel power is currently the only source that can provide the energy density needed in these rugged applications. Future iterations of diesel engines will leverage new technologies, smarter engine designs as well as enhanced virtual models and telematics data.”
“As we think about zero emissions and the path to zero emissions, that change will depend on the energy sources that are available — and also on the applications and regional infrastructure and local regulations around the world. That path to zero will involve a mix of energy-convergent technologies that will use diverse carbon-neutral and renewable energy sources.”
“A consistent message we convey is that we see diesel being around for many years to come, we also expect it to become cleaner and more efficient. Diesel also meets specific power requirements for customer needs that current alternate technologies are not able to competitively meet. Major improvements have been made and there is no reason to expect engineering to slow down now. Emissions reduction is still possible with technologies coming from the on-highway sector focused on reducing NOx output and other constituents. Efficiency gains will be realized through downsizing opportunities, smarter powertrain integration, wider adoption of features like Start/Stop, etc. Diesel still has a long runway and many exciting future advancements should be expected.”
“We’re in an exciting time for diesel engine development. After years refining our technologies to meet subsequent levels of emissions regulations, we can now leverage those technologies in new ways to achieve impressive results.”
Ultra-low NOx and PM emissions are attributed to Cummins Single Module aftertreatment system which integrates DPF and SCR technologies into one easier-to-install package. “The result is a win-win for OEMs and end-users. As well as meeting the power requirements of the sector and the need to reduce emissions, these smaller, lighter, cleaner diesel technologies lower installation costs for OEMs, giving them the opportunity to improve machine capability. Operators can also reduce emissions at the point of use without impacting productivity.”
"Electric mobility is on its way – and that’s good news. This year alone, Bosch is investing 500 million euros in this domain. At the same time, we’re also continuously refining the internal combustion engine – because it’s still needed.”
“Incentivizing modern combustion engines can accelerate the vehicle fleet’s renewal, which would also help the environment and the climate.”
Jeremy Baines, president of Neste U.S., the American unit of a Finnish energy company, is more optimistic. He expects large companies like Amazon, Walmart and UPS to increase their use of the fuel as they look to reduce the carbon emissions of their truck fleets.
“Even if you want to go 100 percent electric, renewable diesel is the only thing deployable and scalable today,” he said.
“The fuels industry continues to reinvent itself. With sweeping changes to emissions, aftertreatment devices, and limits, as well as electricity generated from renewable resources, NBB works to ensure biomass-based diesel fuels provide the performance and benefits required by users, regulators, and the public. We designed each element of our technical program to help ensure higher volumes of biodiesel and renewable diesel may be used in every diesel market segment, growing market access for our members.”
“The science supporting the carbon reduction potential of renewable fuels grows in importance by the day. Studies documenting the lifecycle emissions of biodiesel—including feedstocks, potential indirect land use change, and the fuel production process—show that the carbon reduction potential of our member’s products is increasing. Our consistent message to all stakeholders, Biodiesel: Better, Cleaner, Now, is backed resoundingly by current science. Our sustainability team will continue efforts to ensure laws, regulations, and voluntary carbon reduction pledges properly reflect the sustainable nature of the fuels our members produce.”
