CO2ga

CO2ga is a fictional term used in speculative climate engineering and science fiction to denote a hypothetical gas engineered to interact with carbon dioxide in the atmosphere for CO2 management. It is not a real chemical substance or technology in current scientific practice.

In speculative descriptions, CO2ga is imagined as an inert or only weakly reactive gas with high selectivity for CO2. Proposals vary, but common features include stability under ambient conditions, low toxicity, and the ability to cycle CO2 binding and release with modest energy input.

Proposed mechanisms range from reversible chemical binding of CO2 with the gas to facilitate capture from flue streams, to use as a tracer gas for atmospheric experiments, or as a carrier in distributed sequestration schemes. In each scenario, regeneration and safe handling are central design considerations.

Potential applications discussed in fiction and thought experiments include large-scale carbon capture and storage, enhanced oil recovery optimization, and procedural governance studies for geoengineering. These discussions are theoretical and used to examine tradeoffs, ethics, and risk rather than describe a realized technology.

As a concept, CO2ga serves as a platform for exploring questions of feasibility, safety, and governance surrounding manipulation of atmospheric CO2, without asserting current feasibility or deployment status. It is primarily used to illustrate how such ideas might be evaluated, regulated, and integrated into broader climate strategies.
