Biodiesel refers to a vegetable oil or animal fat based diesel fuel consisting of long chain alkyl is typically made by chemically these oils with an alcohol. Biodiesel is meant to be used in standard diesel engines and is thus distinct from the vegetable and waste oils used to fuel converted diesel engines. Biodiesel can be used alone, or blended with petrodiesel.
There was a recent White House’s announcement calling for expanded production of biofuels (36 billion gallons by 2022 to be exact). But more biofuels is only part of the equation when it comes to reducing greenhouse gas emissions and our reliance on petroleum carbon based fuels. Vehicles must be ready and sometimes converted to this usage.
Enterprise Holdings just announced that it will convert its entire fleet of Alamo Rent A Car, Enterprise Rent-A-Car and National Car Rental airport shuttle buses to biodiesel by spring of this year. That’s more than 600 buses throughout more than 50 North American markets.
