What are the differences between Biofuel, Bioethanol, Biodiesel, and Biogas?

Large-scale commercial biogas projects are proving viable globally. Nordic countries such as Norway and Finland are on board with 1/3 of Oslo city buses powered by biogas from sewage.

The Sustainability Co-Op

By Lauren DeMates.

Put simply, biofuel is energy made from living matter, usually plants. Bioethanol, biodiesel, and biogas are types of biofuels. Biofuels are considered renewable energies, emit less than fossil fuels, and have received increasing attention in the transition to a low-carbon economy.

Bioethanol (aka ethanol) is the most well know biofuel and is an alcohol produced from corn, sorghum, potatoes, wheat, sugar cane, even cornstalks and vegetable waste. It is commonly blended with gasoline. However, plants grown specifically for any type of biofuel are not ideal due to the energy required, environmental impacts, and emissions associated with harvest and transport; not to mention the subsequent increase in global food prices. However, bioethanol production in the U.S. (mostly corn) has been increasing since the 1990s. Almost all gasoline currently sold in the U.S. is 10% ethanol due to the Renewable Fuel Standard (RFS), which dictates the amount of renewable fuel that refiners…

  1. We have very good potential to farm the biofuel like Biogas -Methane instead of growing excess material to the market, and save import of fuel by promotion of Biogas all over the country, at very resonable price like 0.5 USD / Kg (pure methane), and should be connected through PNG pipeline.
