• Collaborative Biodiesel Tutorial

Ethanol production

Biobutanol production

Physiochemical

Thermochemical

Combustion

Gasification

• Hybrid hydrogen-carbon process (H₂CAR)

News:

• Diversified Energy Team wins Department of Defense Renewable Fuel Production Contract, via Biopact, 12 December 2007. The contract is for the development of a portable renewable fuel system based on a gasification technology developed by these companies. The technology will use the waste products of military installations as a feedstock.

Pyrolysis

Depolymerization

Technologies by feedstock

Algae/Algal biodiesel

• "Plankton to Provide Clean New Oil", 4 August 2006, InterPress Service, reported that the Spanish company Biofuel Systems SL (BFS) has developed a photo-bioreactor system to produce "massive amounts of biopetroleum from phytoplankton, in a limited space and at a very moderate cost" and "will be operational in late 2007". It quoted a researcher as saying that "a surface area of 52,000 square kilometres can yield 95 million barrels of biopetroleum per day, in other words an amount equivalent to the entire world production of crude oil at present, and at a considerably lower price."[1]

Biorefining

• Photo-biorefinery

Enzymes

Various important processes in bioethanol production depend on, or can be significantly accelerated by enzymes. Enzymes are for instances frequently utilisend in liquefaction processes complementary to mecanical liquefacion which may be achieved using (continuous) stirred tank reactors or jet cookers. Viscosity reduction is an improtant step before proceeding with starch breakdown (saccharification)in which the biomass fraction is hydrolysed to glucose. Following this step enzymes are also involved in the fermentation process.

Technologies by use

Automobiles

• Biodiesel
• Bioethanol
• Vegetable oil (VO) (Straight vegetable oil (SVO), Waste vegetable oil (WVO))
  • Frybrid - Manufacturers systems for "the conversion of diesel vehicles to use vegetable oil as a fuel."[2]

Village level technologies

The various types of technologies listed above are categorized by the type of reaction that is used to produce bioenergy or fuel. Most of these technologies are mostly being implemented at an industrial scale. However, an exciting area of bioenergy is its applications for addressing poverty and development at the local or village level.

• Multifunctional Platform - The Multifunctional Platform was originally developed through a UNIDO/IFAD regional project in Mali and Burkina Faso from 1994. The multifunctional platform is built around a simple diesel engine, which can also run off pure jatropha oil, that is used to power various tools, such as a cereal mill, husker, alternator, battery charger, pump, etc.

Resources

• UN Energy Matrix The Matrix is an information tool developed by the UN Secretariat, which aims to provide user-friendly information on practical experiences in implementation in the area of energy for sustainable development.
