Alternative Fuels for Trucks

Detailed overview of innovation with sample startups and prominent university research


What it is

Alternative fuels for trucks encompass a variety of energy sources that replace or supplement traditional diesel fuel. These fuels are designed to reduce greenhouse gas emissions and air pollutants, offering a path towards a more sustainable trucking industry.

Impact on climate action

“Alternative Fuels for Trucks” significantly advance climate action by reducing emissions from freight transport, a major contributor to greenhouse gases. Utilizing low-carbon fuels like biodiesel or hydrogen, these trucks offer tangible emission reductions, fostering a sustainable shift in the transportation sector towards a greener future.

Underlying
Technology

  • Biodiesel: Biodiesel is a renewable fuel made from plant-based oils or animal fats. It can be blended with traditional diesel fuel or used as a standalone fuel. Biodiesel is considered a cleaner fuel alternative, reducing greenhouse gas emissions and particulate matter.
  • Renewable Diesel (RD): RD is a synthetic diesel fuel produced from renewable feedstocks, such as vegetable oils or waste fats. It is often referred to as “drop-in” fuel, as it can be used in existing diesel engines without modification. RD offers a cleaner alternative to traditional diesel fuel, with lower emissions and a reduced carbon footprint.
  • Compressed Natural Gas (CNG): CNG is a natural gas that is compressed for storage and transportation. It is used as a fuel for trucks, buses, and other heavy-duty vehicles. CNG engines are more efficient than diesel engines, offering lower emissions and reduced fuel costs.
  • Liquefied Natural Gas (LNG): LNG is natural gas that is liquefied for storage and transportation. It is used as a fuel for long-haul trucks and heavy-duty vehicles, offering a longer range than CNG and reduced emissions compared to traditional diesel.
  • Hydrogen: Hydrogen is a clean and abundant energy carrier that can be used as a fuel for trucks through hydrogen fuel cells. Hydrogen fuel cells convert hydrogen gas into electricity, powering the truck’s electric motors.
  • Synthetic Fuels: Synthetic fuels are produced from non-biological sources, such as coal, biomass, or captured carbon dioxide. They are designed to be compatible with existing internal combustion engines and can be used as a drop-in replacement for traditional diesel fuel.
