Energy researchers have put into service an innovative thermal storage system that uses lime as the storage medium. The lime storage system is a further development of an initial prototype and can store energy more economically and efficiently. Thermochemical storage systems have the potential to save a considerable amount of energy, especially in industrial processes and households.

The battery is the heart of the electric car. Fraunhofer researchers have developed an energy storage device which is significantly more cost-effective over the entire life cycle in comparison with previous models. If one of the more than one hundred battery cells is defective, it can be replaced easily. Until now, the entire battery had to be replaced.

The transportation sector has the capacity to nearly halve its CO2 emissions by 2050 and, hence, to contribute far more than previously thought to mitigate greenhouse gas emissions. Realizing this would require further efficiency improvement and, especially, promotion of public transport in cities, alongside with a large-scale shift to electric cars.
