Energy Vault® - G-VAULT™️ - Gravity Energy Storage

G-VAULT™
Long lasting, long duration technology

G-VAULT™ is a family of gravity energy storage products that decouple power and energy while maintaining a high round-trip efficiency. The G-VAULT™ platform utilizes a mechanical process of lifting and lowering composite blocks or water to store and dispatch electrical energy. The result is a series of flexible, low-cost, 35-year (or more) infrastructure assets designed for large scale shifting of power delivery without any energy storage medium degradation.

Why G-VAULT™

Low Lifetime Cost

Minimize LCOS (Levelized Cost of Storage) with reliable infrastructure designed for minimum 35-year operation.

High Round-Trip Efficiency

Maximize the amount of usable energy with 80+% round-trip efficiency.

Flexible Duration

Adjust the ratio of your energy to power from 4- to 24-hour discharge at GW+ scale.

Safe

Rest easy, knowing there are no electrochemical reactions and zero need for fire protection.

No Degradation

Maintain a constant storage capacity over the life of the system regardless of annual throughput.

Grid-Scale Balancing

Developed for large-scale storage projects, with capability ranging up to 24 hours of duration and lifetime round-trip efficiency of over 80%.

Durability

Utilizes mobile mass composite block storage medium with no capacity degradation attributes of chemical storage or need for augmentation.

Sustainable Design

Circular approach to production, including the repurposing of recycled waste diverted from landfills.

Locally Sourced Materials & Labor

Geared toward community-based installations using local supply chains and labor.

Safety by Design

Introduces a paradigm shift in system safety, removing fire risk from thermal runaway events associated with chemical technologies, and enabling reliable operation in hot or humid environments.
