Augwind is currently developing a storage system that should operate in the energy storage market for the electricity sector. The development of this system is based on Augwind's existing storage system, combined with a unique technology for converting energy stored in compressed air into high-efficiency electrical energy.
Our energy storage system is designed for medium size economies, and will overcome the difficulties of the existing energy storage systems in the market, bearing low costs and high utilization. When completed successfully, the system will serve as an alternative to batteries and other means of energy storage that are currently on the market.
Augwind's storage system, as completed, will provide optimal storage volume for solar farms and wind farms, at much lower prices then the market offers today, with no significant wear and tear and using minimal land area and no harmful environmental impacts.
HIGH CONVERSION RATE
Augwind aims to utilize its unit’s ability to contain large volumes of compressed air to convert the stored air back to energy more efficiently than any other solution.
Augwinds units are able to store immense amounts of air pressure due to the units specially designed ability to harness geo-mechanical forces underground.
Augwind aims to be the most cost-efficient solution on the market by offering both high conversion rates, and low installation costs.
Augwind is currently in the final stages of a pilot program for an energy storage system in the Arava desert, Israel.
The pilot project is designed to demonstrate Augwind’s AirBattery energy storage technology in a small commercial scale.
The program is a cooperative effort alongside the Israeli Ministry of energy and a major Israeli renewable energy company.
This method stores energy in the form of gravitational potential energy of water, pumped from a lower elevation reservoir to a higher elevation. Implementation capability of this technology is directly associated with appropriate topographic location and involves high construction costs and is therefore justified for storage volumes of hundreds of megawatts per hour. Therefore, in most cases this technology is not suitable to the storage demands.
Today, the leading solutions in this field is mainly lithium-ion batteries. These systems are limited to medium-small volumes (up to 100 megawatts), they have high costs and are consumable after relatively few cycles. The systems also include chemicals with adverse environmental effects such as lead, lithium, nickel and cadmium, and require the use of cooling and safety support systems as well as constant monitoring of the battery.
KINETIC ELECTRO-MECHANICAL ENERGY
Kinetic energy is stored in flywheels by cylinders or rotating discs, whose speed decreases as energy flows.The cost of storage (per Kw / h) is relatively high, and there is a permanent and significant loss of energy which rises proportionally to the storage time needed (up to 25% of the total energy per day).
A Behind the Scenes Take on Lithium-ion Battery Prices
This is counter to one of the big trends over the last 30 years whereby automakers divested their supply chain arms. Removing misconceptions around lithium-ion batteries is becoming more important than ever.
Review of energy storage and transportation of energy
Energy storage and transportation are essential keys to make sure the continuity of energy to the customer. Electric power generation is changing dramatically across the world due to the environmental effects of Greenhouse gases (GHG) produced by fossil fuels.
Renewables 2019: Market analysis and forecast from 2019 to 2024
"Renewables are already the world's second largest source of electricity, but their deployment still needs to accelerate if we are to achieve long-term climate, air quality and energy access goals"

Compressed Air Energy Storage (CAES) Systems
Currently, the energy storage is dominated by banks of batteries, but other forms of energy storage are beginning to appear alongside them. CAES is one of them.
