Alternative Fuels for ICE Vehicles

Detailed overview of innovation with sample startups and prominent university research


What it is

Alternative fuels for ICE vehicles encompass a range of non-conventional fuel sources that can power internal combustion engines, offering lower emissions and reduced environmental impact compared to traditional gasoline or diesel. These fuels can be derived from renewable sources, waste materials, or synthetic processes.

Impact on climate action

Alternative fuels for Low-Carbon ICE Vehicles offer a substantial impact on climate action by reducing greenhouse gas emissions. These fuels, like biofuels or hydrogen, lessen carbon footprints, aiding in the transition to cleaner transportation. Their adoption promotes sustainability, mitigating the environmental consequences of traditional fossil fuels and advancing towards climate goals.

Underlying
Technology

  • Biofuels: Biofuels are derived from organic matter, such as plants, algae, or waste biomass. They can be blended with conventional fuels or used in dedicated engines.
    • Ethanol: Ethanol, typically produced from corn or sugarcane, is a common biofuel blended with gasoline.
    • Biodiesel: Biodiesel, produced from vegetable oils or animal fats, can be used in diesel engines.
  • Hydrogen: Hydrogen can be burned in internal combustion engines, producing only water vapor as a byproduct, offering a potentially zero-emission solution.
  • Synthetic Fuels: Synthetic fuels, also known as e-fuels, are produced using chemical processes that combine hydrogen from renewable sources with carbon captured from the atmosphere or industrial emissions. They can be chemically identical to gasoline or diesel, making them compatible with existing infrastructure.
  • Natural Gas: Compressed natural gas (CNG) and liquified natural gas (LNG) are cleaner-burning fossil fuels compared to gasoline or diesel, emitting lower levels of pollutants.
