Compressed Air Energy Storage (CAES)

Demonstration Unit

Serving as a proof of concept (POC) - industrial pilot!

Nitrogen container
3 Phases of 400 Volt

Technological Principle

Proprietary technology can store any type of energy in “Hydraulic Batteries” (accumulators). First, the energy is converted into kinetic rotational energy which operates a hydraulic pump that stores the energy as pressurized oil. Upon demand, a managed release mechanism is discharging the pressurized oil into a hydraulic motor that is connected to a generator, releasing the energy as an electrical current.
