Is Switzerland able to store energy?

The global challenge is not only to produce more energy from renewable sources, but also to be able to store it. With its hydroelectric power plants in the Alps and innovative projects, Switzerland is contributing to the search for solutions for the efficient, long-term storage of electricity.

Which energy storage system uses only air and water?

Uses only air and water with a service life of 20 years The innovative and sustainable energy storage system from Green-Y is based on patented compressed air technology, which stores electricity and also generates heat and cold in a single system. It uses air and water and has a service life of 20 years.

How does Switzerland contribute to the future of electricity storage?

With its hydroelectric power plants in the Alps and innovative projects, Switzerland is contributing to the search for solutions for the efficient, long-term storage of electricity. A journalist from Ticino resident in Bern, I write on scientific and social issues with reports, articles, interviews and analysis.

How does Swiss Energy Vault work?

The Swiss start-up Energy Vault follows the same principle as pumping and turbines. But instead of water, it uses concrete blocks. When there is a surplus of green electricity, these “bricks” are hoisted on top of each other to form a 120-metre tower. They are then “dropped” using gravity to generate electricity.

Are pumped-storage power stations a viable solution for energy transition?

One of the main challenges of the energy transition is to develop systems capable of storing excess energy and returning it when it is needed. Pumped-storage power stations are the most effective and economical solution.

What is a pumped-storage power station?

Pumped-storage power stations are the most effective and economical solution. They allow water to be pumped to a higher altitude when there is an excess energy, and to release generated electricity when there is a shortage. In Switzerland there are about 100 reservoirs for hydroelectric production, and about 15 of them have a pumping system.
