Audi in new e-fuels project: synthetic diesel from water, air-captured CO2 and green electricity; “Blue Crude”

Green Car Congress

Audi’s latest e-fuels project is participation in a a pilot plant project in Dresden that produces diesel fuel from water, CO 2 and green electricity. The sunfire plant, which operates according to the “power-to-liquid” (PtL) principle, requires carbon dioxide, water and electricity as raw materials. PtL = Power-to-Liquids.

Synhelion starts construction of DAWN demo plant to produce solar fuels

Green Car Congress

The solar radiation is converted into high-temperature process heat of more than 1,000°C, then drives the thermochemical reaction to produce solar fuels. The reactor is fed with methane (CH 4 ) and carbon dioxide (CO 2 ) of biowaste origin from a local paper mill, as well as water (H 2 O).

California Energy Commission awards $5M to sugar beet ethanol biorefinery demo

Green Car Congress

The project is slated to use advanced enzyme and microbial techniques to convert 10,000 tons of sugar beets harvested throughout the year into 285,000 gallons of advanced biofuel ethanol. The water in the beets will be captured during processing and recycled so that little water will be used in the plant.
