Department of Energy Releases Request for Information to Achieve Rail Sector Decarbonization

Recognizing that the rail sector generates 2% of U.S. transportation greenhouse gas (GHG) emissions, the Department of Energy (DOE) has released the Progression to Net-Zero Emission Propulsion Technologies for the Rail Sector request for information (RFI) to understand applicable decarbonization strategies. The purpose of this RFI is to solicit feedback from industry, academia, research laboratories, government agencies, other stakeholders, and the public on issues related to alternative propulsion technology advancement within the rail sector and achieving net-zero GHG emissions.

The Biden-Harris Administration has established ambitious goals to address global climate change and is committed to developing and implementing robust and actionable transportation decarbonization strategies. In January 2023, DOE, the Department of Transportation, the Department of Housing and Urban Development, and the Environmental Protection Agency released the U.S. National Blueprint for Transportation Decarbonization, a landmark interagency framework to eliminate emissions from the transportation sector – including rail – by 2050. This significant transition requires rail supply chain coordination, including alternative fuel production, feedstock supply, locomotive engine manufacturing, 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 technically and economically?
  2. What is the timeline for the rail sector to transition to net-zero emission technologies?

The net-zero emission propulsion technologies under consideration for the intent of this RFI for transitional, interim use until 2030 are: biodiesel, renewable diesel, ammonia, methanol, hydrogen fueled internal combustion engines, and ethanol. The technologies under consideration for mid- to long-term use are: hydrogen fuel cells, batteries (tenders or built-in), direct electrification (catenary), or a combination of different technologies.

Jointly released by DOE’s Bioenergy Technologies Office (BETO), Vehicle Technologies Office, and Hydrogen and Fuel Cell Technologies Office, the RFI aims to collect knowledge from stakeholders to guide actions regarding future propulsion technologies, research and infrastructure investments, and coordination to ensure the rail sector is meeting or exceeding U.S. decarbonization milestones.

The RFI is posted to EERE Exchange and Responses must be submitted electronically as Microsoft Word (.docx) attachments to no later than 5:00 pm ET, on January 12, 2024.

This RFI is not a Funding Opportunity Announcement (FOA); therefore, EERE is not accepting applications at this time. EERE may issue a FOA in the future based on or related to the content and responses to this RFI; however, EERE may also elect not to issue a FOA. There is no guarantee that a FOA will be issued as a result of this RFI. Responding to this RFI does not provide any advantage or disadvantage to potential applicants if EERE chooses to issue a FOA regarding the subject matter. Your response to this notice will be treated as information only.

I don't like paywalls. You don't like paywalls. Who likes paywalls? Here at CleanTechnica, we implemented a limited paywall for a while, but it always felt wrong — and it was always tough to decide what we should put behind there. In theory, your most exclusive and best content goes behind a paywall. But then fewer people read it!! So, we've decided to completely nix paywalls here at CleanTechnica. But...
