Evonik and Siemens to use green electricity to produce chemicals from CO2

January 22, 2018 |

In Germany, Evonik and Siemens are planning to use electricity from renewable sources and bacteria to convert carbon dioxide (CO2) into specialty chemicals. The two companies are working on electrolysis and fermentation processes in a joint research project called Rheticus. The project was launched Jan. 18 and is due to run for two years. The first test plant is scheduled to go on stream by 2021 at the Evonik facility in Marl, Germany, which produces chemicals such as butanol and hexanol, both feedstocks for special plastics and food supplements, for example. The next stage could see a plant with a production capacity of up to 20,000 metric tons a year. There is also potential to manufacture other specialty chemicals or fuels. Some 20 scientists from the two companies are involved in the project.
