SUPPLEMENTARY INFORMATION:

The U.S. National Blueprint for Transportation Decarbonization set the goal to achieve net-zero carbon emissions in the transportation sector—including rail—by 2050. This transformation to net-zero emission technologies requires coordination among all aspects of the rail supply chain, including feedstock supply, alternative fuel production, locomotive engine manufacturers, safety implementation, customer demand, and government regulation. To develop a national strategy to decarbonize the rail sector, two critical questions must be addressed:

1—Which alternative rail propulsion technologies are most promising?

2—What is the timeline for the rail sector to transition to net-zero emission technologies?

The purpose of this RFI is to understand what is driving the rail sector towards adopting alternative propulsion technologies, which technologies seem most promising, and what are the key barriers to achieving the transition to net-zero emissions by 2050.

The RFI is available at: https://eere-exchange.energy.gov/​Default.aspx#FoaIdf0ca0a9f-6e0e-4175-b20a-1bdbb682d705.
