Multi-Decadal Decarbonization Pathways for U.S. Freight Rail

Default ARPA-E Project Image

Exploratory Topics
Raleigh, North Carolina
Project Term:
01/07/2022 - 07/06/2023

Technology Description:

The freight rail industry faces pressure to reduce its greenhouse emissions. Currently there is no tool to rigorously identify realistic decarbonization pathways. NC State will quantify the potential of battery-electric, hybrid, and hydrogen-fuel motive power to achieve deep decarbonization over a 30-year planning horizon. The team will develop the Achieving Sustainable Train Energy Pathways (A-STEP) open-source software tool to account for train dynamics, propulsion, energy storage, multi-train interactions, energy delivery, and storage infrastructure. They will consider substitutions, capacity expansion of the power system, levelized cost, and freight demand across a range of scenarios. NC State will apply A-STEP to a national sample of key rail corridors.
