Abstract

A method for ship ballasting includes receiving, at a carbon negative energy storage system, input comprising calcium oxide and water and reacting, within a reaction chamber of the carbon negative energy storage system, the calcium oxide and water to release energy and generate calcium hydroxide. The method includes directing, by the carbon negative energy storage system, the released energy to a requesting end user and providing, by the carbon negative energy storage system, the calcium hydroxide to a marine vessel ballasting system. The method includes releasing a mixture of the calcium hydroxide and ballast water from the marine vessel ballasting system into the ocean to sequester atmospheric CO2.

First claim

What is claimed is:

1. A method, comprising:
receiving, at a carbon negative energy storage system, input comprising calcium oxide and water;
reacting, within a reaction chamber of the carbon negative energy storage system, the calcium oxide and water to release energy and generate calcium hydroxide;
directing, by the carbon negative energy storage system, the released energy to a requesting end user;
providing, by the carbon negative energy storage system, the calcium hydroxide to a marine vessel ballasting system; and
releasing a mixture of the calcium hydroxide and ballast water from the marine vessel ballasting system into the ocean to sequester atmospheric CO 2 .

2. The method of claim 1 , wherein the input further comprises at least one of: calcium metal, magnesium oxide, and magnesium metal.

3. The method of claim 1 , wherein reacting the calcium oxide and water is performed on-shore.

4. The method of claim 1 , wherein reacting the calcium oxide and water is performed aboard a marine vessel.

5. The method of claim 1 , wherein the released energy directly provides power to the requesting end user through an electrochemical mechanism in the form of electric energy.

6. The method of claim 1 , wherein the released energy is thermal energy.

7. The method of claim 1 , wherein directing the released energy to the requesting end user comprises:
directing the released energy to a heat engine; and
directing the output of the heat engine to an electrical generator to facilitate propulsion or onboard electricity generation,
wherein the released energy is thermal energy.

8. The method of claim 1 , wherein releasing a mixture of the calcium hydroxide and ballast water from the marine vessel ballasting system into the ocean to sequester atmospheric CO 2 comprises:
controlling, by the carbon negative energy storage system and according to at least one of a target rate of release, a target volume of release, and a geographic location, the release of the calcium hydroxide.

9. A carbon negative ship ballasting system, comprising:
an energy recovery system configured to react input comprising calcium oxide and water to release energy and generate calcium hydroxide and direct the released energy to a requesting end user; and
a marine vessel, comprising:
one or more ballast tanks configured to receive the calcium hydroxide from the energy recovery system; and
a pumping system configured to pump ballast fluid containing the calcium hydroxide into and out of the one or more ballast tanks, wherein pumping ballast fluid containing the calcium hydroxide out of the ballast tank sequesters atmospheric CO 2 .

10. The system of claim 9 , wherein the pumping system further comprises a material dispensing system comprising one or more independently controlled modules that each release material into ocean water.

11. The system of claim 9 , the marine vessel further comprising:
a sensing system that detects one or more parameters selected from the group consisting of: a geographical parameter defining an area in ocean water, an ocean chemistry parameter, and a material parameter; and
a controller that controls the pumping system according to a target chemical concentration by:
modelling, based on the one or more parameters, a particular aspect of ocean chemistry;
determining, based on the one or more parameters, the modelled particular aspect of ocean chemistry, and the target chemical concentration, a first amount of material and a first rate at which the material is to be released from the ship into ocean water; and
generating a control instruction for the pumping system to release the first amount of the material at the first rate into ocean water.

12. The system of claim 9 , wherein the released energy directly provides power through an electrochemical mechanism in the form of electric energy.

13. The system of claim 9 , wherein the released energy is thermal energy.

14. The system of claim 9 , wherein directing the released energy to the requesting end user comprises:
directing the released energy to a heat engine; and
directing the output of the heat engine to an electrical generator to facilitate propulsion or onboard electricity generation,
wherein the released energy is thermal energy.

15. The system of claim 9 , wherein directing the released energy to facilitate propulsion or onboard electricity generation comprises directing the released energy to a turbine, and wherein the released energy is thermal energy.

16. The system of claim 9 , wherein dispensing the calcium hydroxide into the ocean to sequester atmospheric CO 2 comprises:
controlling, by the carbon negative energy generation system and according to at least one of a target rate of release, a target volume of release, and a geographic location, the release of the calcium hydroxide.

17. The system of claim 9 , further comprising:
two or more shipping standard compliant containers connected by piping, wherein a first container of the two or more containers contains seawater and a second container of the two or more containers contains calcium oxide, each of the two or more containers having a protective bladder lining manufactured according to a target protection parameter based on the calcium oxide; and
a mixing system that is connected to each of the two or more containers by piping; and
a controller that controls the mixing system by providing control signals to the mixing system to control the mixing of calcium oxide and ocean water by controlling the connection between the second container and the first container.

18. A computer-readable storage device storing instructions that when executed by one or more processors cause the one or more processors to perform operations comprising:
receiving, at a carbon negative energy storage system, input comprising calcium oxide and water;
reacting, within a reaction chamber of the carbon negative energy storage system, the calcium oxide and water to release energy and generate calcium hydroxide;
directing, by the carbon negative energy storage system, the released energy to a requesting end user;
providing, by the carbon negative energy storage system, the calcium hydroxide to a marine vessel ballasting system; and
releasing a mixture of the calcium hydroxide and ballast water from the marine vessel ballasting system into the ocean to sequester atmospheric CO 2 .

19. The computer-readable storage device of claim 18 , wherein releasing a mixture of the calcium hydroxide and ballast water from the marine vessel ballasting system into the ocean to sequester atmospheric CO 2 comprises:
controlling, by the carbon negative energy storage system and according to at least one of a target rate of release, a target volume of release, and a geographic location, the release of the calcium hydroxide.

20. The computer-readable storage device of claim 18 , wherein reacting the calcium oxide and water is performed on-shore.
