Harness the potential of long duration energy storage

Long duration storage requires cutting-edge technology. Our gravity energy storage systems combine advanced materials science and machine-vision software to autonomously coordinate balanced storage and dispatch of electricity for grid-scale applications.

Why Long Duration

Long duration energy solutions (LDES) – 4 to 12 hours – will be increasingly required to support energy shifting as variable renewable energy increases its share of the generation mix.

 

Why Energy Vault

Energy Vault’s gravity-based solutions combine time-tested energy storage principles, modern engineering, and cutting-edge materials science to deliver long-duration storage with no performance degradation.

As we develop and commission our gravity solutions globally, we continue to research, develop, and deploy multiple long duration solutions.

Why Energy Vault

Energy Vault’s gravity-based solutions combine time-tested energy storage principles, modern engineering, and cutting-edge materials science to deliver long-duration storage with no performance degradation.

Starting with the first large-scale gravity energy storage project globally, we continue to research, develop, and deploy multiple long duration solutions.

 

Components of your long duration solutions

01.
Long Duration

Offers breakthrough storage capability ranging from 2-18 hours of duration, with competitive economics and lifetime round-trip-efficiency of over 80%.

02.
Durability

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

03.
Supply Chain

Integrates local site materials for composite block construction and relies on standard industrial system components from predictable regional supply chains.

04.
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.

05.
Lifetime Service

Provides unique selection of operations, maintenance, and long-term service agreements over the 35-year technical lifetime of the system, allowing for service tailored to the changing needs of each client and project site.
