Batteries for clean energy

Menu

Reliable + safe

Ambri cells operate with no moving parts in a simple construction that is completely sealed. Systems are designed to provide a redundant system configuration.

After commissioning, the systems do not require heating or air conditioning. They are self-heated and self-regulated. Uniquely, Ambri batteries work best when used daily, unlike lithium-ion batteries that degrade faster with more use.

The batteries are free from the dangers plaguing other batteries, and are tolerant of short circuits, over-charge, and over-discharge. They are not susceptible to combustion (thermal runaway) or ignition from external fire sources. Made with low toxicity substances which are not subject to RoHs restrictions, Ambri cells are safe for transportation and usage worldwide.

Lower cost

The calcium and antimony electrodes in Ambri cells are less than one third the cost of the lithium, nickel, manganese and cobalt in the most common lithium-ion cells. Ambri cells are projected to be priced at less than lithium-ion cells for commercial deliveries starting in 2022.

Lowest system capital cost

Ambri-based systems do not need cooling, fire suppression or module and rack based battery management system equipment, as lithium-ion systems require. Due to minimal degradation, Ambri cells do not require additional energy capacity at the beginning of life or a mid-life augmentation in order to achieve 20 years of operating life. For these reasons, Ambri-based systems are projected to cost 30% – 50% below equivalent lithium-ion systems from 2022 – 2030 even after accounting for the aggressive cell price reductions that are forecast for the incumbent product.

Low operating cost

Ambri-based systems operate without the auxiliary electricity cost for cooling which is an enormous advantage in hot environments where most solar-plus-storage installations are located.

Available materials

The materials inside the system, calcium and antimony, are commonly available as commodities and sourced from multiple locations.

Each GWh of Ambri batteries requires less than 1% of current annual production of these anode and cathode materials.

No cobalt is used in Ambri batteries, a common ingredient in lithium-ion batteries.

Quickly implemented

Pre-fabricated for rapid deployment demands

On site installation of pre-fabricated Ambri-based systems are more rapidly deployed than today’s energy storage technologies that require on-site system assembly. This more closely aligns the installation of Ambri’s energy storage systems with the speed of solar installations.

100MW of solar power plus Ambri storage would be installed within six months. Conventional power plants require over five years.

Modular configuration

Scalable to meet demand for GWh-sized deployments

For GWh-sized deployments, Ambri-based 1-MWh systems are modular and scalable to meet demand.

Easily manufactured cells mean low-cost production plants in each major region.

Robust use with minimal fade

20+ years lifetime

Expect tens of thousands of cycles and decades of operation without the degradation experienced by other battery chemistries.

Not temperature sensitive

High performance no matter the outdoor temperature.

Ambri batteries operate at an internal temperature of 500˚ C which is not dependent on ambient temperature.

Warm climates? Ambri systems operate at maximum performance level no matter the temperature and require no power hungry air conditioning. And, if you need grid-level storage in the Arctic Region, the cold temperatures will have no effect. Ambri batteries are not explosive, combustive, or subject to thermal runaway.

Rapid response capability

Consumers expect electricity at all times without brownouts, blackouts or voltage spikes.

The system is able to provide fast response for frequency regulation applications, while also offering long-duration performance for reserve capacity markets.

Green

Ambri batteries are responsibly produced and their materials can be reused.

The units are made with commonly available and low toxicity materials that are easily recyclable.

Ambri-based systems, which shift energy from peak generation time-of-day to low generation periods, will enable large-scale solar and wind farms to replace coal, oil and natural gas peaker plants.
