The heat storage technology accepts heat in any form as it stores it in high purity graphite. Due to the unique properties of high purity graphite, the heat when stored remains available for use for many days/weeks depending on the rate of energy extraction to the rate of energy replacement.

The storage blocks can accept energy from the grid, wind, wave or thermal systems and convert this electrical energy to heat energy to heat up the block.

The block once heated can then transfer the heat energy to a conventional steam raising system by the embedded heat exchangers. The direct contact method of heat transfer employed is very effective giving rise to one of the most efficient steam raises yet designed.

The steam energy can be used on its own as a boiler replacement or used in conjunction with conventional steam turbines and generators, to produce electricity. This electricity can be either consumed locally or sent to the grid.
