COMPRESSED AIR STORAGE FOR INDUSTRIAL APPLICATIONS

COMPRESSED AIR STORAGE FOR INDUSTRIAL APPLICATIONS

CHALLENGE

Compressed air is an important tool of many manufacturing industries but produces high energy costs. During the compression of air heat is generated which often cannot be used. This leads to high energy losses.

INNOVATION

A novel storage system allows for the storage of compressed air at high pressure. The heat generated during the compression process can be recycled internally, resulting in a high storage efficiency (> 70%). The process can be carried out with simple compressors, expanders and heat exchangers. Due to the high pressure, the space requirement of the compressed-air storage is low.

Integrated into existing compressed air systems, companies can shift their power requirements for compressors to low electricity price times. For example, the compressed air storage can be loaded at night and unloaded during the day. As a result, energy costs can be saved by the reduction of electricity costs, the optimization of in-house electricity production or by avoiding grid charges. In addition, the compressed air storage can be used as a backup system in order to improve availability of compressed air. The invention enables large-scale energy storage at low cost and low system complexity. In con- junction with an energy management system, it is an effective tool for cost-optimized energy supply.

COMMERCIAL OPPORTUNITIES

  • Save electricity and money.
  • Secure availability of your compressed air supply.
  • Increase the flexibility of your compressed air system.
  • Applicable to other gases (e.g., hydrogen) for efficient high-pressure storage
