SWAP Air Vessels System

SWAP’s Innovative Vessels System

SWAP has developed a sophisticated vessels system. Our giant air banks (hundredths of m^3) consists of integration of small volumes. Normally, CAES systems capture the compressed air in one large volume (such as caverns, mines, large vessels), this method limits the ability to control the air pressure, temperature, and flow rate in high pressures. SWAP’s vessels system occupied with unique cooling system which cools the air enabling more efficient compression. Our vessels can be installed above ground and below ground.

SWAP’s Air Battery

SWAP’s solution is disrupting the Energy Storage Systems Market. The company’s approach is uniquely designed for this purpose – technologically and business-wise. SWAP developed a storage system that operates in the energy storage market for the electricity sector. The development of this system is based on SWAP’s existing pilot storage system in the south of Israel, combined with unique technology for converting energy stored in compressed air – water into electrical energy.

SWAP offers an innovative energy storage solution which is compressing air using water pump in “liquid pistons” technology. Our energy storage system is designed for medium size scale and will overcome the difficulties of the existing energy storage systems in the market, bearing low costs and high utilisation. When completed successfully, the system will serve as an alternative to batteries and other means of energy storage that are currently on the market.

SWAP’s storage system, as completed, will provide an optimal storage volume for solar and wind farms, at much lower prices than the market offers today.

SWAP product is using air pressure to store and generate power.

The system consists of several water and air tanks connected through feed pipes to hydro power turbine. 

The liquid pistons are displacing water and air against the force produced by the pressurized air and water tanks through the cylinders, thus provides means for energy storage.


Globally, consumers and manufacturers of electricity are looking for alternatives to cheaper and more available energy. The list of consumers include manufacturing plants, office buildings, research centres, server farms, charging stations for electric vehicles, transmission and distribution networks, and power stations from intermittent sources such as PV and wind farms. Currently, electricity produced by renewable sources is significantly cheaper than conventional gas-fired sources. The ability to store this natural source of energy can gain substantial economic benefits from efficient energy storage system while reducing the environmental damage. 

The energy storage device has been developed by a modular approach, to expand the borders of the relevant target audience as much as possible along the timeline. Therefore, the device has a range of possible uses and capabilities to carry out the necessary compatibility adjustments according to need, to suit all facets of the industry, including private entities, businesses, institutions, municipalities and governmental bodies.

With SWAP’s technology, $/kwh expenses are less expensive than SWAP’s main competitors – batteries.

The energy storage system is fed both by natural and renewable resources, such as sun and wind. Additionally, by storing energy at low-peaks, SWAP exploits energy that otherwise could have been wasted.

SWAP’s storage principle can be developed in a wide range of power demands ranging from tens of KWs to several MWs (designed for medium size scale). Each module can provide a range of power outputs and storage durations. This allows flexibility for customers and not to purchase an exact power need as they have to do with batteries. In addition, customers can easily obtain additional storage hours in a modular plug-and-play manner.

SWAP tackles the challenges of global utility companies and creates substantial, direct and immediate value for the industry, the economy and the environment.
