Benefits of High Elevation Change:
Increased Storage Capacity: A larger height difference allows for lifting the heavy object (usually concrete blocks) further. This translates to storing more gravitational potential energy, essentially increasing the system's total energy storage capacity.

Drawbacks of Needing High Elevation Change:
Limited Deployment Sites: Finding locations with significant and suitable elevation changes can be challenging. This might restrict where these systems can be built.

Alternative:
Focus on Mass and Modest Height: Even with a moderate height difference, a very massive object can store a substantial amount of energy. This approach allows for more flexibility in choosing deployment locations.

Conclusion:
While a high elevation change offers advantages, it's not essential. The key concept is maximizing the gravitational potential energy stored. This can be achieved through a combination of a massive object and a sufficient lifting height, even if the height itself isn't dramatic. This broader perspective opens doors for deploying gravity storage systems in a wider range of locations.
