==SEQUESTRATION OF CARBON IN SUBTERRANEAN VOLUMES - A simplified explanation of the abstract==


This abstract first appeared for US patent application 17948835 titled 'SEQUESTRATION OF CARBON IN SUBTERRANEAN VOLUMES

==Simplified Explanation==

The method described in the patent application involves injecting an aqueous solution and a mixture of silicate nanoparticles suspended in an acidic solution with a pH of less than 4 into a subterranean zone to form a fluid-filled volume. Carbon dioxide is then injected into the volume, leading to the precipitation of carbonate minerals through the reaction of metal cations with bicarbonate formed from the carbon dioxide. The metal cations are produced from the decomposition of the silicate nanoparticles in the acidic solution.

* Injection of aqueous solution and silicate nanoparticles in an acidic solution with a pH of less than 4 into a subterranean zone
* Formation of a fluid-filled volume in the subterranean zone
* Injection of carbon dioxide into the volume
* Precipitation of carbonate minerals through the reaction of metal cations with bicarbonate formed from the carbon dioxide
* Production of metal cations from the decomposition of silicate nanoparticles in the acidic solution

== Potential Applications ==

### Carbon Sequestration Technology for Environmental Remediation

== Possible Prior Art ==
There are existing methods for carbon sequestration, such as injection into geological formations or ocean storage. However, the use of silicate nanoparticles in an acidic solution for enhanced mineral formation may be a novel approach.

=== Unanswered Questions ===

=== How scalable is this method for large-scale carbon sequestration projects? ===
The scalability of this method for large-scale carbon sequestration projects is not addressed in the patent application. Further research and testing would be needed to determine the feasibility of implementing this technology on a larger scale.

=== What are the potential environmental impacts of injecting silicate nanoparticles into subterranean zones? ===
The potential environmental impacts of injecting silicate nanoparticles into subterranean zones are not discussed in the patent application. Additional studies would be required to assess any potential risks or unintended consequences of this technology.


==Original Abstract Submitted==

A method for subsurface sequestration of carbon in a subterranean zone includes forming a fluid-filled volume in the subterranean zone by injecting an aqueous into the subterranean zone and injecting a mixture comprising silicate nanoparticles suspended in an acidic solution having a pH of less than 4. Carbon in the form of carbon dioxide is injected into the fluid-filled volume such that a least a portion of the carbon is sequestered by precipitation of carbonate minerals. At least a portion of the carbonate minerals are formed from reaction of metal cations with bicarbonate formed from the carbon dioxide, and least a portion of the metal cations are a product of decomposition of the silicate nanoparticles in the acidic solution.
