Oak Ridge, Argonne collaborate with Wabtec on hydrogen-powered trains to decarbonize rail business


Researchers from Oak Ridge Nationwide Laboratory (ORNL) and Argonne Nationwide Laboratory (ANL) will work with Wabtec, a number one producer of freight locomotives, to develop the {hardware} and management methods for a single-cylinder, dual-fuel engine to exhibit the viability of utilizing various fuels for locomotives.

The analysis focuses on zero-carbon hydrogen and different low-carbon fuels as viable alternate options to diesel for the rail business. The workforce’s purpose is to scale back carbon emissions from the roughly 25,000 locomotives already in use in North America.

Researchers from the multidisciplinary workforce kicked off the undertaking and celebrated the set up of rail know-how firm Wabtec’s single-cylinder dual-fuel locomotive engine within the Nationwide Transportation Analysis Middle, a DOE-designated consumer facility situated at ORNL, throughout an occasion on 9 November.

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 contains Convergent Science, Inc., a software program developer. The undertaking will run for 4 years.

Hydrogen as gasoline has many benefits, however locomotive engines should be modified to make sure secure, environment friendly and clear operation. The workforce will develop {hardware} and management methods for the engine, which can run on hydrogen and diesel gasoline to exhibit the viability of utilizing various fuels.

Josh Pihl, an ORNL distinguished researcher and group chief for utilized catalysis and emissions analysis stated the undertaking aligns with the objectives of DOE’s Car Applied sciences Workplace to make use of low-carbon fuels in hard-to-electrify transportation sectors.

Whereas electrifying autos is an efficient technique in decreasing carbon emissions from some components of the transportation sector, railways are thought-about tougher due to the excessive price of constructing a single coordinated electrified rail system throughout North America. Annually, the North American rail fleet emits roughly 87.6 billion kilos of carbon dioxide.

To cut back carbon dioxide emissions to internet zero by 2050, we should make dramatic enhancements in vitality effectivity and emissions within the total transportation system, together with railways. Hydrogen has been utilized in light-duty combustion engines. Nevertheless, hydrogen is a more recent space of analysis in railway functions.

The analysis workforce is growing combustion know-how to energy the following technology of trains with as much as 100% hydrogen and different low-carbon fuels. The workforce’s purpose is to design practice engines that can ship the identical energy, vary and cost-effectiveness as present diesel know-how.

Within the undertaking’s first part, the ORNL workforce will work on {hardware} adjustments for retrofitting locomotives. Its 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.

In the course of the second part of the undertaking, ORNL and Wabtec will proceed to change the engine {hardware} to extend the quantity of hydrogen that can be utilized. The workforce goals to switch utterly diesel with hydrogen or low-carbon fuels in new locomotives.

On the identical time, Argonne will leverage greater than a decade of expertise in modeling hydrogen injection and combustion to create a modeling framework to check combustion and emission management applied sciences utilized in hydrogen combustion engines. Specialists in gasoline injection, kinetics and combustion modeling, design optimization, high-performance computing and machine studying will take the undertaking from begin to end.

Scientists are utilizing Argonne’s high-performance computer systems to develop simulation software program. This instrument will assist predict the habits of combustion engines as working circumstances change and {hardware} is modified.

Every diesel-powered locomotive that’s transformed to a zero- or low-carbon vitality supply is anticipated to save lots of as much as 5.6 million kilos of carbon dioxide per 12 months.

Along with Pihl, the ORNL workforce contains analysis engineers Dean Edwards and Eric Nafziger and analysis mechanic Steve Whitted.

Together with Ameen, the Argonne workforce contains group chief and principal analysis scientist Riccardo Scarcelli, postdoctoral fellow Samuel Kazmouz and principal engine analysis scientist Christopher Powell.

The undertaking is funded by the Car Applied sciences Workplace below DOE’s Workplace of Power Effectivity and Renewable Power and by Wabtec. In-kind contributions are supplied by Wabtec and Convergent Science, Inc. The USDepartment of Transportation Federal Railroad Administration can be funding associated analysis on secure use of hydrogen in locomotive engines.
