Scientists at the Forschungszentrum Jülich and the University of Münster have developed a solid-state battery that is very light and durable. It has barely lost any capacity in laboratory tests.

The solid-state battery uses an anode made of lithium, which is separated from the electrolytes by polymer film. It is still in the test phase.

Solid-state batteries have great potential. Because solid state batteries (more…)

DLR wants to turn coal-fired power plants into huge batteries. Salt storage tanks should be heated with surplus electricity. This heat can be used to generate electricity in times of low wind and sunshine.

The salt storages are pink. The cooling towers are needed for continued operation, as well as the turbine house in front of the left cooling tower.

In many companies or private households air conditioners are standard equipment to produce heat or cold. But many coolants damage the climate. And energy efficiency is not far off. Now, engineers at the University (more…)

During plant photosynthesis, mini-reactors transform CO2 and water into bioenergy with light. Collectors capture the photons and feed them to the respective reactor. A new solar technology uses the construction principle to increase the yield.

You can see a large number of sunflowers.

The solar cells constructed on the model of plant photosynthesis achieved an efficiency of more than 40% in tests.

In Hamburg, the first heat flow storage has been completed, which stores surplus electricity in the form of heat. This solution is significantly cheaper than a large battery.

Nuclear powered mini-batteries are small, maintenance-free and long-lasting. Russian researchers have now discovered how they can significantly increase the transit time without releasing dangerous gamma rays. The atomic batteries could be used in cardiac pacemakers.

The nickel-63 isotope, which is a candidate for the nuclear battery, decomposes into harmless beta radiation without generating harmful gamma rays. Therefore, it is from the perspective of researchers suitable for use in medicine. Source: Panthermedia.net/anankkml

The German -spanische Unternehmen Siemens Gamesa has developed the world’s most powerful wind turbine. With ten megawatts, the SG 10.0-193 DD, the prosaic name of the predecessor model, exceeds by 25%. It is (more…)

Scottish scientists are checking the principle of compressed air storage. They are convinced that porous rock strata in the seafloor would be suitable as long-term energy stores.

Coast off Britain

Under the North Sea are rock strata that could probably absorb compressed air.

Surplus electricity could heat storage tanks of liquid metal. This energy can be used to bridge bottlenecks in energy supply. Even natural gas can be used emission-free with liquid metal technology.
