Catalyst and process development, CO2 and energy conversion

Due to geographically distributed availability of fluctuating regenerative energy and CO2, the development of small-scale, decentralized processes is of particular interest. The build-up of small-scale chemical plants is, however, frequently limited by economical boundary conditions.

The Fraunhofer IGB’s Straubing branch “Bio, Electro, and Chemocatalysis BioCat” develops catalysts and processes for the conversion of electric energy and CO2 in liquid energy carriers. Thereby, Fraunhofer IGB BioCat uses and combines the whole spectrum of catalysis (heterogeneous, homogeneous, bio-, and electrocatalysis).

A prominent, first-of-its-class example is a process which combines the CO2-based methanol synthesis with the methanol fermentation to isoprene, lactic acid, poly-hydroxy butyric acid and longer chain hydrocarbons (DE102016203889, WO2017153396). This process enables the cost-efficient further conversion of methanol to products with much higher market price compared to methanol. Therefore, this process has the potential to turn small-scale CO2 valorization into a profitable business.

In the frame of the EU project CELBICON, BioCat aims the combination of electrochemical synthesis of liquid C1-intermediates followed by C1-Fermentation to terpenes. The national project "eleMeMe" set the goal to use the methanol/CO2 system for decoupling the energy generation from consumption. In the EU project CO2EXIDE BioCat also develops processes for the synthesis of CO2-based bulk chemicals, addressing the ethylene, ethylene-oxide, and glycole value chain.

Electrolytic cell for the electrochemical production of hydrogen peroxide

The developed electrolytic cell is based on a technology using gas diffusion electrode. When an electric current flows, water is oxidized at the anode: protons are generated and the pH value decreases. At the same time, the oxygen contained in the air is reduced at the cathode, a gas diffusion electrode, which is also used for example in fuel cells. As a result, the protons are consumed and hydrogen peroxide is generated. The electrolytic cell is operating in continuous mode.

Modular designed systems incorporating these cells can be flexibly adjusted to the customer’s individual need for hydrogen peroxide. Due to an immediate availability without a pre-running start-up process and also a simple switch-off, this technology is suitable for operation with regeneratively generated, but fluctuating available current.

Sorptive heat storage

While generation of power and in several industrial processes large amounts of waste heat are surplus. Compact, adsorptive heat storage systems developed by Fraunhofer IGB can store heat energy, thereby bridging the gap between the time and location heat is available and when resp. where it is needed for heating and cooling applications. Here, heat energy is stored lossless by spatial separation of two components (e.g. zeolite and water vapor) and released during a physisorptive bond of both components when heat is required. The technology has the advantage that very high specific storage densities can be achieved and due to the storage principle no loss of sensible heat occurs during the storage period. Last but not least, the adsorptive heat storages can be operated as heat transformer in order to increase the stored heat temperature level and therefore make use of low temperature waste heat which cannot be utilized otherwise.

At the Energy Storage, a model of the process developed at the Fraunhofer IGB for heat storage by adsorption will be shown
