Liquid metal battery manufacturer Ambri will deploy its first 300-kWh utility pilot system during the first quarter of 2024, a key step towards commercialization, the startup said last week.
Last year, liquid-metal battery maker Ambri set out to raise a $300 million Series F funding round. The money would have fueled its ambitious manufacturing plans, and made good on contracts it had signed for a 140,000 square foot facility in Milford, Massachusetts. and are on par with lithium-ion in installed cost per kilowatt-hour.

From ESS News. Ambri has confirmed the closing of the sale of its assets in accordance with Section 363 of the Bankruptcy Code to a consortium of its lenders, as it prepares to take fresh steps toward commercialization of its long-duration storage technology.
Ambri, a spinout from MIT''s labs, was founded in 2010 and has developed its high temperature battery as a potential low cost, long-duration energy storage resource. It raised US$144 million in an investment round last year, at the same time securing a supply deal for antimony, a key ingredient of its battery''s cathode.
Ambri, the MIT-spinoff commercialising a liquid metal battery for stationary storage applications, looks set for a fresh start. The Massachusetts-headquartered company said earlier this week (31 July) that the sale of its assets has been closed, bought by a consortium of Ambri''s existing lenders, which has also contributed additional capital.
Ambri''s battery technology provides a low-cost, long-duration energy storage resource based on abundant materials and is designed to be safe from the risk of thermal runaway, the company says. It uses anodes of liquid
Ambri, a company known for its patented liquid metal battery technology, has signed its first agreement with a utility provider, Xcel Energy, to bring its technology to the grid. The collaboration will involve a 12-month joint
It claims zero operating cost and maintenance need, and a virtually unlimited lifecycle regardless of charging pattern. Ambri''s battery is comprised of a liquid calcium alloy anode, a molten salt electrolyte and a cathode comprised of solid particles of antimony, which allow for a unique set of operating characteristics that mean it
The contract will see Ambri supply a battery system to serve a 300-megawatt, 1200-megawatt-hour, combined wind, and solar power generation site in the Eastern Cape. In Aug 2022, Ambri announced that it''s been selected by Xcel Energy to build its diverse portfolio of clean, cost-effective, and dispatchable resources to fulfill its
Ambri''s long-duration systems, which are based on its patented technology, are designed to break through the cost, longevity and safety barriers associated with lithium-ion batteries—enabling a critically necessary energy storage solution as increasing amounts of renewable energy are integrated into the grid.
Furthermore, Ambri-based systems do not require the extensive cooling, fire suppression or explosion prevention equipment as lithium-ion systems require. For these reasons, long duration Ambri-based battery systems are a fraction of the cost of lithium-ion when comparing 20-year, long duration systems.
Ambri''s battery components include liquid calcium alloy anodes, molten salt electrolyte and solid particles of antinomy in the cathode. Sadoway said he began developing it as a low-cost technology using widely available raw materials as a possible solution to climate crisis mitigation, as the professor accepted an inventor''s award in June.

Ambri''s cells use a patented calcium-antimony which are claimed to have an expected 20 year lifetime and go to full depth of discharge with "negligible degradation at significantly lower cost than other battery chemistries", an NEC press release said.
Ambri said its liquid metal battery system utilizes commonly available, commercial-grade raw materials including calcium, the 5th most abundant element in Earth''s crust. This makes their platform...
Ambri claims its liquid-metal battery can break through the asserted " cost, longevity and safety barriers" its press release attributes to lithium-ion batteries, the industry''s dominant technology. When Ambri was founded, the lithium-ion price point to beat was around $ 1, 000 per kilowatt-hour.

Their battery has the potential to cost significantly less than existing batteries. By decoupling power supply and power demand, the liquid metal battery will be a major enabler of the widespread use of sustainable energy sources and the development of more efficient power systems. Battery Startup Ambri Hits Ch. 11 With Lender Sale Plans
Ambri, a US technology startup with a novel liquid metal battery that it claims can be suitable for long-duration energy storage applications, has netted a US$144 million investment and signed a deal with a key materials supplier.
Ambri is scaling an advanced long duration energy storage technology that will lower the cost of shifting renewable energy to times of high demand. Ambri Liquid Metal batteries provide: Lower CapEx and OpEx than lithium-ion batteries while not posing any fire risk
Ambri, a grid-scale liquid metal battery company based in Massachusetts, is privately held. Some of Ambri''s claimed benefits are that its batteries and systems are low-cost and have a

Ambri was set up in 2010 and more than a decade later, its energy storage solution has obtained the UL 1973 certification allowing it to be used for stationary as well as motive auxiliary power applications. Ambri’s projected energy storage cost hovers around $200 per kWh, which is almost fifty percent lower than lithium-ion storage.
Ambri Liquid Metal battery technology fundamentally changes the way electric grids operate by increasing the contribution from renewable sources – enabling grid-scale solar and wind farms to replace coal, oil and natural gas peaker plants.
Ambri systems are particularly suited for high-usage applications, such as shifting energy from daytime solar generation to evening and morning peak load times. The batteries are designed to last for durations ranging from 4 to 24 hours. The company is securing customers for large-scale projects with commercial operation dates in 2023 and beyond.
Ambri battery cells are highly tolerant of over-charging or over-discharging, and are not subject to thermal runaway, electrolyte decomposition, or electrolyte off-gassing, each of which could lead to significant safety events with other cell chemistries. Ambri batteries are responsibly produced and their materials can be reused.
Ambri said its liquid metal battery system utilizes commonly available, commercial-grade raw materials including calcium, the 5th most abundant element in Earth's crust. This makes their platform far less expensive to produce than traditional lithium ion systems.
“Our firm has been focused on emerging technologies that provide sustainability solutions now, and Ambri’s one-of-a-kind batteries fit the bill,” said Mark Comora, President of Fortistar.
The European energy storage market is booming with Germany leading residential adoption (+58% YoY) thanks to €500/kWh subsidies. Italy's new tax credits drive 5.2GWh commercial deployments, while UK grid-scale projects exceed 8GWh with 2-hour duration systems. Key selection criteria: German-certified safety (VDE-AR-E 2510), 10+ year warranties, and VPP readiness. Top-performing products include Sonnen's hybrid inverters (98% efficiency) and BYD's Blade Battery (12,000 cycles @80% DoD). For snowy regions like Scandinavia, consider Huawei's -30°C compatible systems. France mandates carbon footprint declarations - Sungrow's ISO-14067 certified solutions gain preference.
For European homeowners, 5-10kWh systems with 3-phase compatibility are ideal. Top picks: 1) Tesla Powerwall 3 (13.5kWh, 97% round-trip efficiency) for smart home integration; 2) LG Chem RESU Prime for compact urban installations; 3) SMA Sunny Boy Storage for retrofit projects. Critical features: EU-made battery cells (exempt from CBAM tariffs), dynamic tariff optimization (like Octopus Energy integration), and fire-safe LiFePO4 chemistry. Southern Europe demands 85%+ depth of discharge capability, while Nordic markets require -25°C operation. Always verify CEI 0-21 compliance for Italian grid connection and EnWG certification for German feed-in.
