About Us

Chex was founded in 2018 by physicist Phd. Christian Romero at Universidad Técnica Federico Santa Maria in Chile.

While studying the limitations and advantages of Compressed Air Storage and Pumped Hydro Storage, we came up with a vision: to combine the best of both worlds in a more practical and sustainable manner. After much testing and tinkering, Compressed Hydro Energy Storage was born.

Our purpose was to make a system that combined the efficiency provided by water with the convenience of compressed-air.

By taking advantage of two of the most abundant elements in the planet, we developed a completely sustainable, easily-scalable and low-cost energy storage solution that does not leave any harmful chemical residues.
