As the US shifts away from fossil gas burning automobiles and vehicles, scientists on the U.S. Division of Power’s (DOE) Argonne Nationwide Laboratory and Oak Ridge Nationwide Laboratory (ORNL) are exploring choices for one more type of transportation: trains. The analysis focuses on zero carbon hydrogen and different low-carbon fuels as viable alternate options to diesel for the rail {industry}.
Each laboratories have entered into cooperative analysis and growth agreements with Wabtec, a number one producer of freight locomotives. The Argonne and Wabtec settlement additionally consists of Convergent Science, a software program developer. The mission will run for 4 years.
Researchers from the multidisciplinary group kicked off the mission and celebrated the set up of rail expertise firm Wabtec’s single cylinder dual-fuel locomotive engine within the Nationwide Transportation Analysis Heart, a DOE-designated person facility situated at ORNL, throughout a Nov. 9 occasion.
“Whereas hydrogen has been utilized in light-duty combustion engines, it’s nonetheless a really new space of analysis in railway functions.” — Muhsin Ameen, Argonne senior analysis scientist
Hydrogen as gas has many benefits, however locomotive engines should be modified to make sure secure, environment friendly and clear operation. The group will develop {hardware} and management methods for the engine, which is able to run on hydrogen and diesel gas to reveal the viability of utilizing various fuels.
“We’re excited to be part of this collaboration as a result of it addresses the necessity to decarbonize the rail {industry} by advancing hydrogen engine expertise for each present and future locomotives,” stated Josh Pihl, an ORNL distinguished researcher and group chief for utilized catalysis and emissions analysis. “It is usually an ideal instance of how a DOE-funded collaboration between {industry} and nationwide laboratories can speed up the event and commercialization of applied sciences to assist scale back carbon emissions from transportation.”
Pihl stated the mission aligns with the targets of DOE’s Automobile Applied sciences Workplace to make use of low-carbon fuels in hard-to-electrify transportation sectors. Whereas electrifying automobiles is an efficient technique in lowering carbon emissions from some elements of the transportation sector, railways are thought of harder due to the excessive value of constructing a single coordinated electrified rail system throughout North America. Every year, the North American rail fleet emits roughly 87.6 billion kilos of carbon dioxide, a serious driver of local weather change.
Researchers are exploring the potential of hydrogen combustion engine expertise within the rail {industry}, stated Muhsin Ameen, Argonne senior analysis scientist. Hydrogen is an power service that may be produced from clear power sources resembling photo voltaic and wind energy. Scientists have studied hydrogen-powered automobiles for many years.
“To cut back carbon dioxide emissions to web zero by 2050, we should make dramatic enhancements in power effectivity and emissions within the total transportation system, together with railways,” stated Ameen. “Hydrogen has been utilized in light-duty combustion engines. Nevertheless, hydrogen is a more recent space of analysis in railway functions.”
The analysis group is creating combustion expertise to energy the following technology of trains with as much as 100% hydrogen and different low-carbon fuels. The group’s purpose is to design prepare engines that may ship the identical energy, vary and cost-effectiveness as present diesel expertise.
“This collaboration with Argonne and Oak Ridge nationwide laboratories with DOE assist will advance the event of hydrogen expertise inside Wabtec’s present industry-leading platforms for medium-speed engines. Railroads will have the ability to significantly scale back emissions and working prices whereas sustaining commonality inside their present fleet of trains,” stated James Gamble, vp of Engine & Energy Options Expertise at Wabtec.
Within the mission’s first section, the ORNL group will work on {hardware} adjustments for retrofitting locomotives. Their purpose is to scale back CO2 emissions from the roughly 25,000 locomotives already in use in North America. Locomotives have a service lifetime of greater than 30 years, so changing your complete fleet would take a long time.
Throughout the second section of the mission, Argonne will leverage greater than a decade of expertise in modeling hydrogen injection and combustion to create a modeling framework to review combustion and emission management applied sciences utilized in hydrogen combustion engines. Consultants in gas injection, kinetics and combustion modeling, design optimization, excessive efficiency computing and machine studying will take the mission from begin to end.
On the identical time, ORNL and Wabtec will proceed to change the engine {hardware} to extend the quantity of hydrogen that can be utilized. The group goals to utterly exchange diesel with hydrogen or low-carbon fuels in new locomotives.
Scientists are utilizing Argonne’s excessive efficiency computer systems to develop simulation software program. This device will assist predict the conduct of combustion engines as working circumstances change and {hardware} is modified. Simulations assist researchers perceive the combustion course of, which drives engine effectivity and reduces emissions.
Every diesel-powered locomotive that’s transformed to a zero- or low-carbon power supply is anticipated to avoid wasting as much as 5.6 million kilos of carbon dioxide per yr.
Together with Ameen, the Argonne group consists of group chief and principal analysis scientist Riccardo Scarcelli, postdoctoral fellow Samuel Kamouz and principal engine analysis scientist Christopher Powell.
Along with Pihl, the ORNL group consists of analysis engineers Dean Edwards and Eric Nafziger and analysis mechanic Steve Whitted.
The mission is funded by the Automobile Applied sciences Workplace beneath DOE’s Workplace of Power Effectivity and Renewable Power and Wabtec. In-kind contributions are offered by Wabtec and Convergent Science. The U.S. Division of Transportation Federal Railroad Administration can also be funding associated analysis on secure use of hydrogen in locomotive engines.
