Switzerland storage energy technologies

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.

What is the future of electricity storage in Switzerland?

One important pillar of this strategy is the further development of electricity storage capacity in Switzerland. In the next years, three large-scale pumped hydro storage power plants will be connected to the grid. The first, the Limmern pumped storage plant (1 GW), should become operational in 2016.

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 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.

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.

Why is Switzerland taking part in battery 2030?

Switzerland is taking part in the European research initiative Battery 2030, which aims to improve the longevity and energy density of conventional lithium-ion batteries so that fewer rare metals are used. Stationary systems that can stockpile renewable energy are also set for massive expansion in the coming decades.
