Chemical energy storage

The success of the turnaround in energy policy, in the course of which power generation from renewable energies in Germany is to be constantly expanded, depends on an extension of the power networks; however, new technologies are also required to store surplus energy. Thus energy storage systems insure a rapid balancing out of grid loads and make electrical energy available again at a later point in time. In addition to battery storage, chemical energy storage systems can also provide an effective solution.

Center for Energy Storage

Project duration: July 2012 – June 2019

development of processes for the production of liquid and solid chemical energy carriers with the assistance of electrical energy. It is true that there are already several promising ways of producing suitable energy carriers such as the power-to-gas technology.

Fraunhofer Lighthouse Project "Electricity as a Raw Material"

The energy transition in Germany is in full swing. Renewable energy sources contributed 24 percent of the 630 TWh of electrical power generated in 2013. Their proportion is estimated to climb to 80 percent by 2050, while at the same time greenhouse gas emissions are expected to fall to 80 percent of the comparative 1990 figures. The associated expansion of wind power and photovoltaics will result in a considerably increasing rise of power available from fluctuating energy sources. As an industrialized country, Germany is confronting the pressing question of whether and how the expected excess in the electrical grid can be coupled cost-effectively to energy-intensive manufacturing operations.
