There are a wide range of fuels that can qualify as advanced biofuels, and these fuels can often provide innovative low-carbon solutions for specific use cases. The primary requirement is that any advanced biofuel attain a minimum 50 percent reduction in greenhouse gas emissions compared to the fossil based fuel it replaces. Many of these advanced biofuels are also fungible in existing infrastructure, allowing distribution and use without requiring any changes to the supply system.  These are commonly termed  “drop in” fuels. Examples of both drop-in and other advanced fuels that can be produced and/or blended include:

Distillates

• Renewable diesel
• Biodiesel
• Renewable heating oil
• Sustainable aviation fuel (SAF)

Ethanol

• Cellulosic and sugarcane ethanol

Specialty fuels

• Isobutanol
• Dimethyl Ether
• Naphtha
