Abstract
There is provided a system for energy storage and CO2 capture. The system comprises CaO/CaCO3, a carbonator (1) adapted to react CaO with CO2 to produce CaCO3, at least one CaCO3 storage container (2) for receiving and storing the CaCO3 produced in the carbonator (1), wherein the CaCO3 storage container (2) is configured to be transportable such that the CaCO3 can be supplied to a geographical location (3) remote from the carbonator (1) for CO2 release.
Claims15
A system for energy storage and CO2 capture comprising:
- CaO,
- a carbonator adapted to react CaO with CO2 to produce CaCO3,
- at least one CaCO3 storage container for receiving and storing the CaCO3 produced in the carbonator,
- characterized in that the CaCO3 storage container is configured to be transportable such that the CaCO3 can be supplied to a geographical location remote from the carbonator for CO2 release
- the system further comprising
- a calciner located at a geographical location remote from the carbonator and adapted to heat the CaCO3 of the transportable CaCO3 storage container to a temperature where CO2 is released to produce CaO,
- at least one CaO storage container for receiving and storing the CaO produced in the calciner, and
- at least one storage for released CO2,
- wherein the carbonator and calciner are located at least 0.5 km apart, and
- wherein the CaCO3 storage container is configured to be transportable so that it can be connected to, pulled along by or loaded into some kind of transportation device.
7 more elements
A method for storing energy and capturing CO2 comprising the steps of:
- connecting a transportable CaCO3 storage container to a carbonator by connecting CaCO3 container input means of the CaCO3 storage container to carbonator CaCO3 output means of the carbonator,
- providing CO2 and CaO to the carbonator to capture CO2 and thereby producing CaCO3 and
- transferring the CaCO3 to the transportable CaCO3 storage container via said carbonator CaCO3 output means and CaCO3 container input means.
- transporting the transportable CaCO3 storage container to a remote geographical location, said transporting involving transporting the transportable CaCO3 storage container at least 0.5 km, said transporting further involving the CaCO3 storage container being connected to, pulled along by or loaded into some kind of transportation device,
- transferring the CaCO3 of the transportable CaCO3 storage container to a calciner, and
- supplying heat to the calciner to produce CO2 and CaO,
- transferring the CaO produced in step f to a transportable CaO storage container,
- transporting the CaO storage container to a carbonator for capturing CO2 and thereby producing CaCO3,
- storing the CO2 produced in step f.
