Fraunhofer Lighthouse Project eOPT »Electricity as a Raw Material«

Electrochemical Processes for Fluctuating Energy and Raw Materials Systems

Overall Objective

Germany has decided to transform its energy supply in order to reduce harmful emissions: away from fossil fuels and radioactive materials and towards sustainable energy production from renewable sources. Energy, primarily in the form of electricity, is supplied over a decentralized distribution grid. The fluctuation in the price for electricity because of environmental factors presents a chance for electricity-intensive industries to choose the lower-cost electricity as their primary energy source. The aim of this project is to demonstrate this opportunity to the chemical sector.

In collaboration with other Fraunhofer institutes, electro-chemical processes are tested and modeled as an alternative to conventional chemical reactions, and subsequently, implemented and optimized by means of practical demonstrators. Specifically, the project focuses on the production of hydrogen peroxide as a green bleaching agent and the conversion of CO2 into valuable basic chemicals, both by means of electrochemical conversion processes.
