Imports without guarantees are not competitive

Green hydrogen from Africa much more costly than previously assumed

To meet Europe’s demand for green hydrogen, governments and the private sector have high hopes for production in Africa. A study led by the Technical University of Munich (TUM) has now shown that the financing costs for production facilities in African countries would be much higher than previously assumed. Only 2 percent of around 10,000 investigated locations would be competitive for exports to Europe. This would require price and offtake guarantees from European governments.

Solar battery based on porous organic material

Sunlight in - power out, long after sunset

This material acts like a solar reservoir – storing energy and releasing it as electricity long after sunset. The captured solar energy can thus also be used to supply electricity in the dark. For the first time, it has been possible to combine solar harvesting and long-term energy storage in a single, metal-free molecular framework – effectively merging the functions of a solar cell and a battery into a single, lightweight, and sustainable system.

TUM researchers develop new material for solid-state batteries

World record for lithium-ion conductors

Solid-state batteries are considered a key technology for the future: they can store more energy and do not rely on flammable materials like current lithium-ion batteries. Researchers at TUM and TUMint.Energy Research have now taken a significant step towards improving solid-state batteries. They developed a new material made of lithium, antimony and scandium that conducts lithium ions more than 30% faster than any previously known material.

Energy laboratory for school classes

Renewable energies and technology you can touch

How do you get children and young people interested in renewable energies and the energy transition? A research group at the Technical University of Munich (TUM) has come up with a solution: a laboratory for sustainable energy systems. Here, schoolchildren can observe the energy consumption of household appliances in real time. In this way, the team aims to make technology and sustainable energy systems tangible.

Training neural networks more efficiently

New method significantly reduces AI energy consumption

The enormous computing resources needed to train neural networks for artificial intelligence (AI) result in massive power consumption. Researchers at the Technical University of Munich (TUM) have developed a method that is 100 times faster and therefore much more energy efficient. Instead of taking an iterative approach, the parameters are computed directly based on probabilities. The results so far are comparable in quality to existing iterative methods.

Why do plants transport energy so efficiently and quickly?

Quantum mechanics helps with photosynthesis

Photosynthesis - mainly carried out by plants - is based on a remarkably efficient energy conversion process. To generate chemical energy, sunlight must first be captured and transported further. This happens practically loss-free and extremely quickly. A new study by the Chair of Dynamic Spectroscopy at the Technical University of Munich (TUM) shows that quantum mechanical effects play a key role in this process. A team led by Erika Keil and Prof. Jürgen Hauer discovered this through measurements and simulations.

Investment in Germany's technological sovereignty

Battery start-up incubator launches at TUM

To strengthen Germany's technological sovereignty in the field of battery technologies, the Battery Start-up Incubator (BaStI) is being established at TUM. Funded with 3.3 million euros by the Federal Ministry of Education and Research (BMBF), BaStl, as an integral part of the TUM Venture Labs, will support and advise start-up applicants from all over Germany in the first phase. The aim is to accelerate the market entry of new battery technologies from research and thus reduce dependence on imports.

E-conversion Cluster of Excellence

Creative ideas for the energy transition

In the e-conversion Cluster of Excellence, experts are researching the mechanisms of energy conversion, providing crucial foundations for the energy transition. What are the research highlights? What is the secret to the cluster's success and why is Munich the perfect place to explore the renewable energies of the future? We take a look behind the scenes with Prof. Jennifer L.M. Rupp (TUM School of Natural Science) and Prof. Thomas Bein (Department of Chemistry, LMU Munich).

Strategic partnership on optoionics between TUM and Max Planck Society

World's first center for solar batteries

The world's first center for solar batteries and optoionic technologies is being established in Bavaria. The Technical University of Munich (TUM) and the Max Planck Society (MPG) have set the course for this with the support of the Bavarian Ministry of Economic Affairs. With the SolBat Center, a unique research ecosystem will be formed to research new types of energy storage systems and develop applications to use solar energy even more efficiently and flexibly.
