Within our project we aim to use regenerative energy sources and carbon dioxide to produce bulk chemicals, e.g isobutanol. This system will be executed in Escherichia coli. An electricity source will be used to generate a current which reduces a mediator. The mediator is taken up by the bacteria where the mediator is oxidized. The energy of this reaction will be further utilized to bind atmospheric carbon dioxide. One of the resulting intermediates is pyruvate. In our project pyruvate will be used to produce isobutanol.

For the next weeks we aim to contact different firms and stakeholder who should help us to get insights in solving our problems.

• What:
• A biological production of bulk chemicals in three modules. Frist electricity is used for the growth. Secondly carbon dioxide is bound with supplied energy. The third module produces a product like isobutanol with an intermediate of the carbon fixation.
• Why:
• The project addresses several problems. A main problem is the transport and storage of electricity. We aim to convert excess of electricity into isobutanol. The second problem is an increasing amount of carbon dioxide which results in global warming. The target is to use this amount as a useful carbon source. Another problem is the depletion of crude oil which we engage by producing a part of biodiesel.
• Where:
• Energy producing sites: Wind engine, hydroelectric power stations, solar energy power stations, …
• While driving production: Cars, ships, space stations, …
• Product dependent sites: varnish producers, emollient producers, …
• Who:
• Many different stakeholders are engaged by this project. On the one hand there are all car drivers or electricity users. On the other hand there are industrial production site employees
• When:
• The system can be used whenever energy is available.
• How:
• The system can be settled next to wind parcs or mounted on the envelope of a space station
• A new construction plan has to be made for cars
