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.

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 Switzerland generate electricity?

Switzerland already generates most of the electricity it consumes from renewable energies (75%), mainly via hydroelectric power stations. In recent years there has been an increase in photovoltaics, and to a lesser extent in wind power. Solar panels are popping up all over the country, even in the most unthinkable places.

Will Switzerland become Europe's 'electricity battery'?

As the Alpine glaciers slowly melt away, Switzerland will have the opportunity to build new dams and artificial lakes in the mountains. This will increase energy storage capacity in the Alps, strengthening Switzerland’s role as Europe’s “electricity battery”.

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 Swiss power stations better than other countries?

Compared to other Alpine countries, such as Austria, Germany and Italy, Swiss power stations generally have larger water-retention basins and are therefore able to operate over longer periods, notes the Association of Swiss Electricity Companies.
