Batteries for clean energy

the battery that will change the world

grid-scale storage systems for solar and wind energy

an evolution of the electric grid

Electricity demand worldwide is growing as populations and digital economies are increasing Massive growth in the renewable energy generation market is driving expected global energy storage market growth of 6x over the next several years. By optimizing the transmission, distribution and integration of generation assets, Ambri batteries meet the demand for large-scale, affordable energy storage.

Massive infrastructure investment is needed in the electricity grid worldwide. Renewable power generation and energy storage is a smarter, faster and less expensive infrastructure improvement choice. Storage will change how electric systems are engineered – building to average demand rather than peak.

Solutions for customers with high energy demands

Utilities, IPPs, and developers are looking for Ambri-based systems to provide consistent, responsive electrical power for transmission and distribution grid applications as well as behind-the-meter customers that demand reliable energy, such as large industrial sites,
hotels, hospitals, and datacenters.

Electricity on days without wind or sun

As the cost of renewables declines, an increasingly larger portion of electricity will be generated by intermittent resources. However, wind and solar power generators can’t produce electricity on days without wind and sun, limiting their level of effectiveness. Grid-scale energy storage systems act as a ‘buffer’, smoothing out power from wind and solar farms, enabling their broad-scale displacement of fossil fuel generators.

our process

Ambri’s Liquid Metal Battery™ technology solves the world’s biggest energy problems – fundamentally changing the way power grids operate by increasing the contribution from renewable resources and reducing the need to build traditional power plants. Ambri’s long duration energy storage solution is built for daily cycling – even in extreme, harsh environments. With a lifespan of 20+ years with minimal fade, Ambri systems are not only extremely reliable but also safe as Ambri systems do not produce or emit any gases and no possibility for thermal runaway.
