Evonik and Siemens launch phase 2 of Rheticus: butanol, hexanol from CO2 and water using renewable electricity and bacteria

Green Car Congress

The goal is to develop an efficient and powerful test plant that will use carbon dioxide and water as well as electricity from renewable sources and bacteria to produce specialty chemicals. Evonik and Siemens are now combining these two, previously separate, plants in a test facility at Evonik’s site in Marl (Germany).

Mercedes-Benz Cars plants in Germany to be supplied with CO2-neutral energy from 2022

Green Car Congress

In Germany, all Mercedes-Benz plants will be supplied with CO 2 -neutral energy. From 2022, the production of our Mercedes-Benz plants in Germany will operate CO 2 -neutral. Thereby, we completely forego coal-based electricity and obtain our electrical energy from only renewable sources. The plant will start operating in 2019.

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.

Audi opens power-to-gas facility in Werlte/Emsland; e-gas from water, green electricity and CO2

Green Car Congress

The Audi e-gas plant, which can convert 6MW of input power, utilizes renewable electricity for electrolysis to produce oxygen and hydrogen. Because there is not yet a widespread hydrogen infrastructure, the hydrogen is reacted with CO 2 in a methanation unit to generate renewable synthetic methane, or Audi e-gas. Earlier post.).

Bauhaus Luftfahrt analysis finds solar thermochemical jet fuel production viable only if CO2 captured from renewable sources and not flue gases

Green Car Congress

A team from Bauhaus Luftfahrt in Germany has analyzed the climate impact and economic performance of solar thermochemical jet fuel production. The solar thermochemical fuel path is based on the high-temperature conversion of water and CO 2 into syngas (hydrogen and carbon monoxide) and oxygen mediated by ceria redox reactions.
