Radically scalable energy storage using underground gravity batteries

Terrament is building cheap, long-duration energy storage using underground gravity batteries. Our patent-pending design beats the competition by maximizing both height and weight:

First, we achieve 10 times more height than above-ground solutions by digging a mile deep into bedrock.

Second, we achieve maximum density by designing each module to support its own weight.

Terrament is poised to lead this incredible market opportunity expected to top a trillion dollars globally by 2050.
