Chocolate that harnesses the full potential of the cocoa fruit

Researchers at ETH Zurich have teamed up with the food industry to produce a whole-fruit variety of chocolate. This helps increase the value creation of cocoa farming – and is healthier.

Using solar energy to generate heat at high temperatures

Instead of burning coal or oil to produce cement or steel, in the future solar energy could be used for this purpose. Researchers at ETH Zurich have developed a thermal trap that can absorb concentrated sunlight and deliver heat at over thousand degrees Celsius.

Mosaic grassland landscapes are the most beneficial

Like forests, grassland provides numerous ecological, economic and social benefits. Researchers have investigated ways to maintain and improve these benefits in the Swiss canton of Solothurn.

ETH Zurich spin-offs develop high performance batteries

The electrification of many areas of life is leading to an increased demand for high-performance batteries. Two ETH spin-offs are making waves in this field: while BTRY develops high-performance solid-state batteries, 8inks is working on a new standard for production.

The energy transition will require popular supports

To achieve a decarbonized world, clean energy sources will have to be widely adopted – yet there’s a range of obstacles in the way. A number of EPFL researchers are studying these obstacles and mapping out strategies for getting past them. Here’s a look at some of their findings.

Strengthening Swiss hydropower with science

Researchers at ETH Zurich led by Robert Boes are developing specific solutions to optimise electricity production from Swiss hydropower plants. This will ensure that hydropower remains the backbone of Switzerland’s electricity supply in the future.
