Advancing Affordable, Efficient, and Clean Transportation

Clean Cities and Communities is a U.S. Department of Energy (DOE) partnership to advance clean transportation nationwide. More than 75 DOE-designated Clean Cities and Communities coalitions work locally in urban, suburban, and rural communities to strengthen the nation’s environment, energy security, and economic prosperity. As partners with DOE’s Vehicle Technologies Office (VTO), coalitions work to deploy affordable, efficient, and clean transportation; energy efficient mobility systems; and fuel-saving technologies and practices.

Coalition Expertise

Coalition staff provide the technical expertise local decision makers and fleets need to bring clean transportation solutions to their communities. This expertise includes how to:

Evaluate clean transportation options

Develop strategies to reduce emissions

Build collaborative relationships

Shift to efficient and clean transportation energy sources

What is Renewable Diesel?

It is NOT Biodiesel

While both Renewable Diesel and Biodiesel share the same feedstocks - vegetable oil and animal fats;

  • Chemically equivalent to petroleum diesel, but much cleaner
  • Can be blended with petroleum diesel in any amount
  • Requires no changes to engine, fueling systems or handling
  • Meets all the same ASTM standards as petroleum diesel
  • Production capacity more than doubled in the U.S. from 2022 to 2024
    • Jan 22 = 1.8 bg/y to Nov 23 = 3.9 bg/y

Higher Cetane = higher combustion efficiency = increased fuel efficiency = lower emissions

New Plants in the last year

  • Montana Renewables’ plant in Great Falls, MT (Calumet)
  • Cheyenne Renewable Diesel in Cheyenne, WY (HF Sinclair)
  • New Rise Renewables’ plant in Reno, NV
  • Seaboard Energy’s plant in Hugoton, KS

Jan 2022

8 New Plants in 2022-2023

  • Dakota Prairie Refining in Dickinson, ND (Marathon)
  • Wyoming Renewable Diesel in Sinclair, WY (HF Sinclair)

Production

Traditional hydrotreating—Used in petroleum refineries, hydrotreating involves reacting the feedstock (lipids) with hydrogen under elevated temperatures and pressures in the presence of a catalyst. Commercial plants currently use this technology.

CO2 Emission Benefits

  • up to 33% lower levels of fine particulates
  • up to 24% lower carbon monoxide (CO) emissions
  • up to 9% fewer nitrogen oxides (NOx)
  • reduced levels of polyaromatic hydrocarbons (PAH)
  • up to 30% fewer hydrocarbons (HC)

California Air Resources Board

77% less

Typical claims: 65-75% fewer CO2 emissions

21 of 52

Emissions and GHG

  • Renewable diesel has some of the highest greenhouse gas (GHG) reduction scores among existing fuel pathways in programs such as the federal Renewable Fuel Standard (RFS), the California Low-Carbon Fuel Standard (LCFS), the Oregon Clean Fuels Program, and the Washington State Clean Fuels Program.

$63,000/year fuel premium = 8 electric transit buses

8 electric transit buses would cost about $7,200,000��So, you could run RD for 114 years for the cost of 8 eBuses��Or, simply running R12 = 1 eBus

$7,560/year (Fuel Premium) = CO2 reductions on par with an $800,000 eBus
