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 is plant and animal matter, including energy crops, wood, grasses, algae, vegetable oils, and agricultural and municipal wastes.
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.”
- 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)
|Hawaii’s current use of petroleum-based fuels (million gallons/yr)||1,800||Algae oil yields demonstrated on Kauai||2,000 gal/acre|
|Hawaii’s current cost per gallon of biofuels||$2.90||Hawaii’s potential liquid biofuel waste production (mil gal/yr)||97|
|Hawaii’s current cost of kWh for biofuel generated||40¢/kWh||Hawaii’s potential ethanol production from energy crops||1,202|
