About TerraStor

The problem we're solving:

The energy transition cannot happen without cheap and effective energy storage. Renewable energy is intermittent by nature. As renewable penetration grows past ~25% on any particular grid, this intermittency creates a major challenge for grid operations, which must constantly balance electricity supply with demand. Energy storage is therefore needed to absorb the intermittent supply of renewable energy and dispatch it to the grid reliably, enabling a full energy transition.

Our solution:

TerraStor’s ACAES plants provide very large-scale storage solutions to the grid that are responsive, flexible, and very cost effective. Their plants offer long to very long duration (8-24+ hours) storage to meet a variety of grid needs in balancing renewable energy supply.

Our differentiator:

TerraStor's plants are larger in scale and longer in storage duration than competing technologies.

Their solution is mechanically simple and utilizes abundant features of nature (air and geology) to offer the most economic grid-scale storage solution, particularly for long-duration storage.

Their solution is commercial-ready, leveraging existing technologies from the oil and gas and power industries.

The construction and operation of our plants do not depend on supply-constrained raw materials or significant land use.

Our biggest achievement:

They have developed a process design with a high round-trip storage efficiency. This design is based on currently available powertrain technology and modern cavern engineering techniques.

They have identified, through extensive geologic research and analysis, a list of developable sites for their technology.
