Researchers develop a new candidate for a cleaner, greener and renewable diesel fuel (PhysOrg.com) — A class of chemical compounds best known today for fragrance and flavor may one day provide the clean, green and renewable fuel with which truck and auto drivers fill their tanks. Researchers at the U.S. Department of Energy’s Joint BioEnergy Institute (JBEI) have engineered Escherichia coli (E. coli) bacteria to generate significant quantities of methyl ketone compounds from glucose. In subsequent tests, these methyl ketones yielded high cetane numbers – a diesel fuel rating comparable to the octane number for gasoline – making them strong candidates for the production of advanced biofuels

UConn reactor uses more efficient process to make biodiesel fuel

Deep inside the University of Connecticut’s chemical engineering building in Storrs, Professor Richard Parnas and a team of students quietly monitor a murky brown emulsion bubbling inside an enormous 6-inch diameter glass tube like doctors carefully observing a patient undergoing surgery.

Parnas’ patented biodiesel reactor is unique in both its simplicity and efficiency. In conventional biodiesel production, vegetable oil is converted into biodiesel fuel and glycerol, a byproduct of the conversion process. Then, the glycerol must be mechanically separated from the diesel fuel, as part of a two-step process. Parnas’ reactor is different in that it uses gravity, heat, and natural chemical reactions to make the biodiesel and separate the glycerol in one step.

UC Davis News & Information :: More, Better Biodiesel
Yields of biodiesel from oilseed crops such as safflower could be increased by up to 24 percent using a new process developed by chemists at UC Davis. The method converts both plant oils and carbohydrates into biodiesel in a single process, and should also improve the performance characteristics of biodiesel, especially in cold weather.

Solazyme | Technology
Solazyme’s renewable oil production technology allows us to do in a matter of days what it took nature millions of years to do. Our unique, indirect photosynthesis bioproduction process uses microalgae to convert biomass directly into oil and other biomaterials, a process that can be performed in standard commercial fermentation facilities cleanly, quickly, and at low cost and large scale. Our renewable oil and bioproducts technology has manufactured thousands of gallons of oil and hundreds of tons of biomaterials that are tailored not only for biofuel production, but also as replacements for fossil petroleum and plant oils and compounds in a diverse range of products from oleochemicals to cosmetics and foods

The CODA is the outcome of the only Brown-RISD joint studio, Out of Gas! The objective of the studio, was to design and build an alternative commuter vehicle that runs on biodiesel fuel for use in Providence, RI, and readily adaptable for use in Kisumu, Kenya. The students were a mix of Brown engineers and RISD industrial designers, split into interdisciplinary teams. (via CODA Alternative Vehicle | Better x Design)
