Concrete energy storage Switzerland

Can you store green energy in giant concrete blocks?

Finding green energy when the winds are calm and the skies are cloudy has been a challenge. Storing it in giant concrete blocks could be the answer. The Commercial Demonstration Unit lifts blocks weighing 35 tons each.

Where is a battery made out of concrete?

A couple of hours south of Zürich, Switzerland, in the Canton of Ticino, you’ll find a battery made out of concrete blocks. Energy Vault, the Swiss clean energy firm that built it, is about to go public via a SPAC merger with Novus Capital Corporation II. The sun doesn’t always shine, nor does the wind always blow.

Could concrete blocks be the most expensive part of a Energy Tower?

Concrete blocks could potentially be the most expensive component in an Energy Tower. Although concrete is cheaper than alternatives like lithium-ion batteries, Energy Vault would need a large quantity of concrete to construct hundreds of 35-metric-ton blocks. So Pedretti explored another solution.

Does concrete store more energy than water?

Concrete stores more energy than water when considering the energy required to lift an equal mass. This is because concrete is denser than water. Bill Gross, a long-time US entrepreneur, and Andrea Pedretti, a serial Swiss inventor, developed the Energy Vault system that utilizes this principle.
