Compressed air energy storage

Compressed air energy storage (CAES) is a way to store energy generated at one time for use at another time using compressed air. At utility scale, energy generated during periods of low energy demand (off-peak) can be released to meet higher demand (peak load) periods.

The foundation aims to contribute to Japan’s international efforts on the environment, sharing project collaborations as well as promoting Japan’s rich conservation knowledge and experience in developing nations.

  • A Novel Solid Oxide Electrolysis Cell with Improved Efficiency and Durability

    Type: 
    Product
    Technology:

    Northwestern researchers have developed the ability to store large-scale electrical energy for renewable energy sources such as wind and solar. Established energy storage technologies such as hydroelectric water pumping and underground compressed air storage are limited to specific geographic sites and most batteries and ultracapacitors have limited energy storage capacities and times.

  • Industrial wastewater treatment

    Type: 
    Product

    Emefcy’s EBR for industrial wastewater treatment is based on three components new to biological wastewater treatment: - Anodes (in anaerobic conditions): Where the bacterial oxidation of the organic matter occurs - Cathodes (which are exposed to air): Where the corresponding reduction reaction takes place - An electrical circuit that includes the external load connecting the anodes to the cathodes. A biofilm naturally develops on the anode oxidizing the organic matter into carbon dioxide.

  • Compressed Air Energy Storage (CAES)

    Type: 
    Product
    Objective:

    Compressing air is a way to store energy, and combining this with a generator yields a way of storing electricity. Systems have been in use in applications such as starting large engines or in the propulsion of mine locomotives. At a larger scale, the technology is used to shift the energy demand for smaller and larger electricity grids, providing storage. Air heats up when compressed, and cools down when decompressed, generating a natural barrier for efficiency. To counter this, some installations use an external source of heat, like natural gas. Efficiencies up to 45% are attainable.
