LTS-Flywheel for 12 hour energy storage

01.01.2010 - 30.06.2013

Research funding project

Flywheels are a sustainable solution for decentralized energy storage. They offer longer life cycles (over 25 years), no requirement for maintenance, and usage of harmless, easily available materials, compared with other storage technologies, as for example accumulators. Flywheels, available up to now, are designed for short term energy storage in the region of minutes. The technological challenge within this research project is the development of fundamentals for a technology leap - Long Term Storage flywheel. Aim is a significant increase in storage time (12 hours at 80% load efficiency). Additionally, high reliability and low system costs are defined as project aims. This LTS-flywheel shall allow decentralized storage of electrical energy, for instance pro-duced in in-house photovoltaic systems. Therefore, it is an essential contribution for developing the technological basis for the building of the future, especially the positive energy house.
