## Summary

Claudio Spadacini, Founder and CEO of Energy Dome, explains how his company uses compressed CO2 to create a long-duration grid energy storage system called the 'CHU battery.' He details the thermodynamic cycle involving compression, thermal energy storage in water tanks, and expansion through a turbine, highlighting the system's 75% round-trip efficiency and 30+ year lifespan. Spadacini discusses Energy Dome's strategy of standardizing units to achieve economies of scale, reducing costs below lithium-ion batteries, and expanding into the US market.
