Abstract

A carbon capture system includes two carbon capture plates. A first carbon capture plate collects carbon dioxide from a flow of ambient air. A second carbon capture plate releases carbon dioxide upon application of heat from a heat exchanger. The heat is exhaust heat from a data center. The first carbon capture plate and the second carbon capture plate are rotatable between the capture and release positions. The carbon capture system uses the waste heat from a data center to collect and store atmospheric carbon dioxide, thereby reducing the concentration of atmospheric carbon dioxide.

First claim

What is claimed is:

1. A carbon capture system, comprising:
a housing including an inlet and an outlet;
a support structure located in the housing, the support structure including a first plate support and a second plate support, the support structure being rotatable to move the first plate support and the second plate support between a capture position and a release position, wherein the capture position is located between the inlet and the outlet;
a first carbon capture media connected to support structure at the first plate support;
a second carbon capture media connected to the support structure at the second plate support;
a heat exchanger, a hot side of the heat exchanger thermally connected to the support structure at the release position; and
a carbon collection system positioned to collect carbon released at the release position.

2. The carbon capture system of claim 1 , wherein the heat exchanger receives heat from a data center.

3. The carbon capture system of claim 1 , wherein the heat exchanger includes a heat source.

4. The carbon capture system of claim 1 , wherein the carbon collection system includes a carbon dioxide separator.

5. The carbon capture system of claim 1 , wherein the carbon capture system includes a compressor and carbon storage tank.

6. The carbon capture system of claim 1 , further comprising an outlet fan at the outlet, the outlet fan being rotatable to draw air from the inlet to the outlet.

7. The carbon capture system of claim 6 , further comprising an inlet fan at the inlet, the inlet fan being rotatable to push air from the inlet to the outlet.

8. The carbon capture system of claim 1 , wherein the capture position is located in a capture chamber and the release position is located in a release chamber.

9. The carbon capture system of claim 1 , further comprising a bypass between the capture position and the outlet.

10. The carbon capture system of claim 9 , further comprising a mixing chamber at the bypass, the heat exchanger extending into the mixing chamber.

11. A carbon capture system, comprising:
a housing including an inlet and an outlet;
a chamber in the housing, the chamber including:
a carbon capture module, including:
a capture position between the inlet and the outlet;
a release position;
a first carbon capture media;
a second carbon capture media;
a support structure supporting the first carbon capture media and the second carbon capture media, the support structure being rotatable to move the first carbon capture media and the second carbon capture media between the capture position and the release position;

a heat exchanger including a hot side and a cold side, the hot side being proximate to the release position;

a hot fluid line connected to a cooling system for a data center, the hot fluid line providing hot fluid to the hot side of the heat exchanger; and
a cold fluid line connected to the cold side of the heat exchanger and returning cold fluid to the cooling system.

12. The carbon capture system of claim 11 , wherein the hot side of the heat exchanger includes a quick-release connection to the hot fluid line.

13. The carbon capture system of claim 11 , wherein the cooling system is a liquid immersion cooling system.

14. The carbon capture system of claim 11 , further comprising a carbon storage mechanism in a release chamber at the release position.

15. The carbon capture system of claim 14 , wherein the carbon storage mechanism includes a re-use circuit between a carbon storage tank and one or more of the cooling system or an HVAC system.

16. A method for carbon capture, comprising:
flowing ambient air from an inlet in a housing of a carbon capture system, across a first carbon capture media located at a capture position in the housing, and out an outlet of the housing, the first carbon capture media absorbing carbon dioxide from the ambient air;
heating a second carbon capture media using exhaust heat from a data center cooling system, the second carbon capture media being located at a release position in the housing, the second carbon capture media releasing carbon dioxide into a release chamber;
capturing the carbon dioxide in the release chamber with a carbon storage mechanism; and
rotating the first carbon capture media from the capture position to the release position and the second carbon capture media from the release position to the capture position.

17. The method of claim 16 , wherein flowing the ambient air includes flowing the ambient air at a temperature of less than 35° C.

18. The method of claim 16 , wherein rotating the first carbon capture media and the second carbon capture media includes rotating 180°.

19. The method of claim 16 , wherein capturing the carbon dioxide includes compressing the carbon dioxide and storing the carbon dioxide in a carbon storage tank.

20. The method of claim 16 , further comprising training a machine learning model based on input from the carbon capture system.
