Sodium-ion batteries have several advantages over conventional batteries. They contain no critical raw materials such as lithium or cobalt - and could make stationary energy storage and electromobility much more cost-effective. There is still a lack of the necessary energy storage materials for production.
A research project by the ZSW in southern Germany is developing environmentally friendly energy storage systems for both urban transport and stationary applications.

A study by the University of Hohenheim has shown that agriculture benefits from shading the soil with solar systems, especially in dry regions. This is because less water evaporates, which the plants need.
Researchers not only want to further develop printable solar cells technologically. Rather, they want to provide solutions with them in order to implement different application variants.
The manufacturer of commercial storage batteries Tesvolt and the University of Magdeburg want to cooperate on scientific projects in the future. They want to research new approaches to energy storage and further develop battery technologies.

The structured facade elements collect solar heat and transfer it to the heat pump circuit. In this way, they can raise the flow temperature for heat pumps.
In a study, researchers from the IÖW and the HSK in Kehl examined agriphotovoltaics economically, ecologically and legally. There are still hurdles. But above all, the technology offers plenty of opportunities for farmers.
Instead of a toxic solvent, ZSW researchers in Germany have used a water-based chemical to produce cathodes with a high nickel content. The batteries produced with this chemical are not only more environmentally friendly, but also last longer.
To increase the efficiency of concentrating solar thermal power plants, researchers have found a solution to avoid heat loss. They also use a more compact design and a new heat transfer medium.
The Bi-Clever pilot project has now shown that the degree of self-sufficiency of solar system owners with e-cars can more than double through bidirectional charging. A stationary battery storage system actually increases the self-sufficiency to 59 per cent.
A gymnasium roof in Eppingen shows how a solar system can discreetly disappear into the building envelope. The BIPV system has 66 kilowatts and produces at least 90 per cent of the electricity generated by a conventional solar power system with uncoated glass.
