AMBRI : la batterie haute température Calcium Antimoine liquide

[energy_isere]

J'ai découvert ça grâce à un vidéo postée sur forum bulle immo.

http://www.bulle-immobiliere.org/forum/ ... 3#p2312153

La seconde vidéo parle quand même de la start up qui s'est montée sur cette affaire.
Le site http://www.ambri.com

Faut que je regarde ça.

Il y a tout juste deux ans Ambri à levé 50 millions de dollars, et Bill Gates et Total ont amené des ronds.

Le gars qui porte ça s'appelle Donald Sadoway

Feb 2017 ......
But it’s also a bizarrely simple concept, at least to an electrochemist. It turns out assembling a cell of a liquid metal battery cell is as easy as dropping a plug of metal, made up of two alloys of different densities, into a vessel and pouring some salt on top. When the cell is powered up, the two metals melt and divide into two layers automatically, like salad oil floating on vinegar. The molten salt forms a layer between them, conducting electrons back and forth.
.......

.......
The molten metal battery has long since moved out of the basement lab. In 2010, Sadoway started the battery company Ambri with several of his former students, then moved HQ into a manufacturing facility 30 miles west of Cambridge to the town of Marlborough. Now, Ambri employs about 40 people and is busy building prototype battery packs out of hundreds of the molten metal cells.

Sadoway says Ambri is less than a year away from deploying its first commercial models. All signs have been hopeful so far, he says. At the manufacturing facility, some test cells have been up and running for almost four years without showing any signs of wear and tear. Getting the assembled battery packs, each consisting of 432 individual cells, to work was trickier. But after ironing out some pesky issues with the heat seals, the battery packs can reach a self-sustaining operating temperature, hot enough to charge and discharge without any extra energy input. Now Ambri is in the middle of raising another round of funding, enough to reach market-ready production mode.

Et voilà deux articles qui tiennent la route sur la technologie.

https://www.wbur.org/bostonomix/2017/03 ... en-battery

L'intérieur de la batterie est à 900 degré Fahrenheit, soit 482 degré Celcius.
Chaud devant.

80 % de rendement.

Inside the box it's 900 degrees but outside it's cool to the touch. The system is about 80 percent efficient, but Giudice says very little energy is wasted.

"The inefficiency, that 20 percent of inefficiency, is actually given off as heat," Giudice says, "and that heat is held within the insulated box that holds the cells and that's sufficient to keep it at operating temperature, and you just charge and discharge to keep it at that state."

Et dans article plus récent de juillet 2018

......
Sadoway’s battery is liquid-based and remains in that state as it operates at temperatures ranging from 400°C to 700°C. The essential components include a high-density liquid metal (bismuth today) at the bottom of the cell, a molten salt atop that, and a low-density liquid metal (lithium) above the salt. The two liquid metal layers serve as electrodes, while the molten salt acts as an electrolyte. The difference between the metals gives rise to the battery’s voltage.

The 1,000-cubic-foot version of the battery can store about 1 MWh of energy—about 250 kW with a four-hour drain time in many cells that are each about the size of a pizza box. Sadoway says a smaller version of the battery, roughly the size of a refrigerator, could eventually be marketed for energy storage in single-family homes
.......

Les investisseurs :

........ During the first few years, Sadoway funded his basic research effort with backing from France-based Total Group and the US DOE’s Advanced Research Projects Agency-Energy. Eventually, however, he launched a private company, Ambri, Inc., using funding from a variety of private sources, including Total Group, Bill Gates, Khosla Ventures, and the Pritzker family.

Sujet à suivre pour voir comment ils arrivent (ou pas) à industrialiser.

Le Bismuth fond à 271 Degré celcius
Le Lithium à 180 Degré


C'est une techno impeccable pour le stockage stationnaire.

[energy_isere]

Le Bismuth ça vaut quand même 10 000 dollar la tonne.

https://www.metalbulletin.com/Article/3 ... urces.html

La fiche USGS sur le Bismuth donne une production mondiale de 14 000 tonnes, dont 11 000 viennent de Chine et 2000 du Laos.
Presque rien ailleurs.

Le Bismuth ne se trouve pas (tres rarement) sous forme de minerai, mais est plutôt co-produit avec le plomb et le Tungstène.
Les réserves de Bismuth...... Ne sont même pas chiffrées par l' USGS.

La Chine posséderait 75 % des réserves mondiales avec 240 000 tonnes.

Est ce que le Bismuth est vraiment un bon candidat ? C'est à se demander.

[Glycogène]

Je ne comprends pas pourquoi il n'utilise pas du plomb à la place du bismuth. On a du plomb à ne plus savoir qu'en faire.
Le bismuth est autant toxique que le plomb, et est aussi règlementé, donc ce n'est pas la raison.

A un moment donné ils ont essayé l'Antimoine, puis des alliages de Plomb et Antimoine.

Puis au Bismuth.

US utility to demonstrate liquid metal long-duration storage at solar test site
US utility Xcel Energy will test the use of Ambri’s energy storage technology at the Solar Technology Acceleration Center.

AUGUST 29, 2022 RYAN KENNEDY

Ambri, a developer of liquid-metal long-duration energy storage systems, has revealed plans to partner with Colorado electric utility Xcel Energy on a demonstration project. The project will demonstrate the ability of Ambri’s calcium-antimony liquid metal batteries to interact with renewable energy.

MRI Global’s Solar Technology Acceleration Center (SolarTAC) will be the host site for the demonstration project. The SolarTAC was established to test renewable energy technologies in real-world, grid-connected environments.

Ambri’s chemistry is being developed to meet the demands of large industrial energy customers, such as data centers. The company’s large-scale battery unit has 250 kW/1,000 kWh of capacity, DC efficiency of more than 80% under a wide set of use cases, a response time of less than 500 milliseconds, and voltages between 550 V to 1,150 V.

It is housed in a 10-foot shipping container. The system holds shelves of cells, thermal management systems, a weatherproof outer enclosure, and a battery management system for applications that require high energy capacity, frequent cycling, long lifetimes, and high efficiency.

Xcel Energy is the first utility in the United States to set a long-term goal of providing its customers with zero-carbon electricity. It aims to be net-zero across electricity, heating, and transportation by 2050. Ambri’s technology is designed to perform in a wide range of environments, potentially making it the right fit for Xcel to effectively store and dispatch power in harsh Colorado weather conditions.

The SolarTAC has been owned and operated by MRI Global since 2011. It will test Ambri’s technology for one year. In addition to solar and energy storage, the site is used to test microgrid capabilities at the edge of the electric distribution system.

In 2020, Ambri signed a deal with TerraScale, a clean infrastructure development company, to deliver 250 MWh of Ambri systems to TerraScale’s Energos Reno data center project. The site’s battery will be bolstered by a reported 500 MW of on-site renewable generation.
