Innovative Technologies for geo-Energy Storage Systems (geo-ESS)

About Us

CleanTech Geomechanics Inc (CTG) is a Canadian company developing innovative technologies for geo-Energy Storage Systems (geo-ESS).

CTG developed the concept of Cased-Wellbore Compressed Air Storage (CWCAS) for renewable energy storage. CWCAS is an advanced Compressed Air Energy Storage (CAES) process; and is a high-pressure, low-volume CAES process. CWCAS geo-ESS enhances the versatility and application of this energy storage approach.

CWCAS Advantages

  • Versatile energy storage that is easily scalable, site independent and cost-effective.
  • CWCAS can rapidly increase the amount of reliable renewable energy in electricity supply systems.
  • Storage of off-peak, excess, or irregular power from renewable energy sources - to reduce congestion and curtailment.
  • Designed for grid, off-grid and behind-the-meter applications.
  • CWCAS is not site-specific; it can be utilized anywhere, including near existing transmission infrastructure.
  • CWCAS Integrates easily with solar and wind farms.
  • Low environmental footprint compared to other energy storage technologies, such as batteries and pumped hydro storage. 
  • CWCAS is safe and has a long life-cycle (20 – 25 years).
  • Mobilization, installation, and commissioning times of a CWCAS facility are relatively short and cost-effective.
  • CWCAS geo-ESS is a viable alternative to large-scale battery ESS.
