Woche der Umwelt

Federal President Frank-Walter Steinmeier and the Deutsche Bundesstiftung Umwelt (DBU) are hosting the Digital Week of the Environment. Under the motto “This is how the future works!”, exciting discussions and an attractive specialist program on important future issues are planned for June 10 and 11, 2021. Exhibitors from business and technology, research and science, and civil society will present their innovative solutions for the future online.

Fraunhofer IKTS was selected as one of the exhibitors by an expert jury appointed by the Federal President. Within the digital exhibitor portal, we present our research themed

“Hidden Champion” Ceramics - Storing Electricity and Filtering Water with Ceramics

High-performance ceramics is a “hidden champion” – inconspicuous but with amazing properties. The material group is used wherever metal and plastic reach their limits. Fraunhofer IKTS will present two applications at the Week of the Environment.

Efficient and sustainable – a battery made of ceramics

In the context of the energy transition, renewable energy sources such as photovoltaics or wind power are becoming increasingly important. To ensure that electricity is available even when the sun is not shining or the wind turbine is at a standstill, energy must be reliably stored.

Researchers at the Fraunhofer Institute for Ceramic Technologies and Systems IKTS, Europe's largest research facility for ceramics, have developed a ceramic sodium nickel chloride battery for this purpose that can not only be manufactured cost-effectively, but also consists entirely of non-critical, domestic raw materials. The ceramic battery can be used as a home storage system or as a sustainable, safe, and low-cost community storage system.

Circular industrial process through filtration – process water treatment

Water plays an important role in many production processes: e.g. as a solvent in synthesis, as a coolant or for washing. Careful use of this resource is essential – but water treatment and wastewater treatment are cost-intensive. For this reason, industry worldwide is being called upon to recycle water in its processes. This requires efficient separation technologies, in which polymer membranes are most commonly used. However, these reach their limits at high temperatures and under aggressive chemical conditions. This is where ceramics can show their advantages: the material has a high hardness and strength, is chemically resistant and insensitive to high temperatures. Fraunhofer IKTS, Europe's largest ceramics institute, develops ceramic filtration membranes and complete systems for treating industrial process wastewater.
