1 - 10 Days
Gravity Storage
Up to 100MW – 100MWhrs
Utilising Abergeldie’s expertise in constructing large blind bored shafts, a heavy mass is suspended in an enclosed shaft storing potential energy. When energy is needed to firm and stabilise electrical networks the mass is allowed to drop converting the potential energy of the suspended mass via a generator and delivering synchronised electrical energy to a network. When renewable energy is plentiful the mass is again lifted to its charge position ready for the next cycle.
Our largest energy storage system, providing hundreds of megawatts over many hours to days. This system uses the potential energy stored in a large reservoir at an elevated position. When energy is required water is released from the elevated storage via a turbine that produces electrical energy. When energy is plentiful, the process is reversed, and water is returned to the upper storage ready for the next cycle.
- Long-term high-power support for networks and micro grids.
- Provides grid stability and inertia over hours to days.
- No degradation in capacity / output over repeated charging / discharging cycles
- High cycle efficiency.
Hydraulic Storage
up to 100MW – 200MWhrs
Utilising Abergeldie’s expertise in constructing blind bored shafts, a large piston and cylinder is constructed underground. From its charged position, potential energy of the piston at the top of the shaft forces water through a turbine which is connected to a generator supporting the electrical network when renewable energy cannot meet system requirements. The system is tailored to suit the specific needs and can be adapted for fast discharge over a short time or longer durations.

The Missing Link to a Green Hydrogen Future
Abergeldie and ITP Thermal established Ardent Underground Pty Ltd to provide economical and safe underground hydrogen gas storage tanks. Economical hydrogen storage is the missing link in the carbon neutral future promised by the green hydrogen transition. Ardent Underground uses the Abergeldie blind boring methods to provide the missing link.
