Abstract
Various configurations of a power plant are described. The power plant is configured to supply power to a receiving electrical grid by the combustion of metal powder. The power plant is also configured absorb power by recovering the metal powder from the metal oxide produced by the combustion of the metal powder, with electricity from a source electrical grid.
Claims20
A power plant configured to operate in a first mode wherein it supplies power to a receiving electrical grid, and in a second mode wherein it absorbs power from a source electrical grid, wherein:
- in said first mode, the plant is configured to produce electricity using metal powder as fuel;
- in said second mode, the plant is configured to store energy by using the electricity from the source electrical grid to recover the metal powder from metal oxide;
- and
- the receiving electrical grid and the source electrical grid are the same electrical grid.
A method of storing and producing electricity, comprising the following steps:
- absorbing energy from a source electrical grid by using the electricity of the source electrical grid to recover metal powder from metal oxide;
- producing energy by using the recovered metal powder as fuel;
- and
- supplying the produced energy to a receiving electrical grid wherein the receiving electrical grid and the source electrical grid are the same electrical grid.
A system for storing and producing electricity by means of metal powder, comprising:
- a power production module connected to a receiving electrical grid, the power production module being configured to produce electricity and metal oxide by the combustion of metal powder, and to supply the produced electricity to the receiving electrical grid;
- and
- a metal powder production module connected to a source electrical grid, the metal powder production module being configured to absorb electricity by recovering the metal powder from the metal oxide with electricity from the source electrical grid,
- wherein the receiving electrical grid and the source electrical grid are the same electrical grid.
