December 21 (Renewables Now) - SGL Group, a German supplier of carbon-based products, has supplied components for a large-scale redox flow wind battery in Pfinztal, southwestern Germany.

The battery, described as currently the largest in Germany, is part of a research project, called RedoxWind, at the Fraunhofer Institute for Chemical Technologies (ICT). When completed it will be capable of storing 20 MWh of electricity. It will store wind generated power and supply it to the grid on demand.

SGL has provided carbon fiber felts and bipolar plates that act as positive and negative electrodes, the company said last week. By March 2018, it will deliver the last parts to customer J Schmalz GmbH, an automation firm which is in charge of assembling the redox flow stack.

The research project is aimed at demonstrating that the energy system is both economically viable and can provide reliable power, the company explained. The project is supported by the state of Baden-Wuerttemberg and the Federal Ministry of Education and Research with EUR 19 million (USD 22.5m).

According to information about the project by Fraunhofer ICT, the battery will be connected directly to the intermediate direct current (DC) circuit of a 2-MW wind turbine.
