Bioenergy
Bioenergy comes from organic materials (anything that used to be alive or part of a living thing: leaves, branches, wood chips, paper, algae, manure). Biomass can be used to produce electricity; can be converted into liquid fuels (called “biofuels”); or can be burned to produce heat for cooking or other uses (such as wood in a barbecue grill).
Biomass
Biomass is plant and animal matter, including energy crops, wood, grasses, algae, vegetable oils, and agricultural and municipal wastes.
Biofuels
Biofuels are liquid fuels made from biomass. As defined in Chapter 486J-1 of the Hawaii Revised Statutes, “Biofuels means liquid or gaseous fuels produced from organic sources such as biomass crops, agricultural residues, and oil crops, such as palm oil, canola oil, soybean oil, waste cooking oil, grease, and food wastes, animal residues and wastes, and sewage and landfill wastes.”
They include:
- Ethanol
- Biodiesel
- Bio-based diesel fuel (also known as green diesel)
- Bio-based gasoline (also known as green gasoline)
- Bio-based jet fuel (including hydrotreated renewable jet and alcohol-to-jet)
- Bio-based pyrolysis oils
- Hydrogen (from biomass sources)
