Augwind's Storage System - AirBattery - Brings the Storage World Breakthrough News

23 Dec 2020

Augwind (TASE: AUGN) announces the results of the tests performed in the proof of technological feasibility stage and assessment of the efficiency of the AirBattery system. The overall efficiency of the system in the context of commercial facilities with a capacity above five megawatts is expected to be in the range of approximately 75-81%, depending on the characteristics and the various requirements of each storage project, and the storage system components it comprises.

According to Or Yogev, CEO and Founder of Augwind, "The data presented by Augwind today is excellent news for the world of renewable energies in general and the world of energy storage in particular, both in comparison with lithium batteries and alternative storage solutions. Augwind's AirBattery system has an energy efficiency that is generally similar to the efficiency of pumped storage stations.

"Compared to a storage system based on lithium batteries, despite their higher initial efficiency, lithium batteries have an obvious disadvantage in that their efficiency and structural capacity fade over the years and necessitate replacement and upgrade for a new storage system every few years or cycles. In addition, lithium-ion systems contain chemical components, some of which are not recyclable, while Augwind's solution is designed for decades, while also being green, environmentally friendly, and based solely on water and air."

The advantages of the AirBattery system compared with existing systems:

  • It's green news: with compare to electro-chemical batteries that require complex supply chain, AirBattery is a first of its kind system, made from water and air. 
  • It's a storage system with decades-long life-span with compare to lithium batteries which require replacement and upgrading every few years. 
  • It's a safe underground storage system that does not require daily maintenance unlike lithium batteries, which require air conditioning systems and strict temperature control (for safety purposes). 
  • It provides uniform and fixed efficiency that does not fade compared with battery efficiency, that fades over the years and in consequence require replacement and upgrading with a new battery system. 
  • It's a multi-use system that allows for an unlimited number of cycles. 
  • It's a modular storage system, enablinga range of storage volumes from tens of megawatts per hour and through to hundreds of megawatts per hour without geographic dependency and at a competitive cost compared with lithium-ion technologies. 
  • Unlike lithium-ion systems that are inherently at risk of catching fire, the AirBattery system, which is made of air and water, is an underground system that is green and safe both in the operational aspect and in the security aspect (it's protected from rockets).

Dr. Yogev further added: "Augwind's AirBattery system, in addition to high efficiency, is breakthrough news as it provides a better solution vis-à-vis lithium battery solutions at almost every possible level. Our storage system, the first of its kind, is made of water, air and earth, which distinguishes it from other storage systems, some of which pollute. AirBattery can be used inexhaustibly without any degradation in performance over decades. Our additional significant advantage lies in our abilities to construct a modular storage system and create storage stations from tens of megawatts per hour and through to hundreds of megawatts per hour without any geographic dependence and at a low cost compared with lithium technologies.

"Any entrepreneurial company setting up solar farms must today address the huge environmental damage caused by using polluting storage systems that are dangerous to the environment compared with the tremendous advantage of AirBattery. A storage solution based on lithium batteries is an environmentally polluting system in the process of manufacturing the batteries, the use of metals that are not readily available, such as lithium, cobalt and nickel, and above all the inability to recycle the batteries at the end of their lifecycle.

"The efficiency data we announce today are based on a beta AirBattery system installed at Yakum at the beginning of the year, which has been tested over many months at all levels of its technology, applied in practice in compression processes using pumps, storage in AirX tanks, and discharge using water turbines. Each charge-discharge cycle was examined from end to end and tested for efficiency. The figures we present today are based on continuous measurements conducted over the past months."
