Geoengineering Methods

Geoengineering Methods

From snatching carbon dioxide (CO2) out of the air like trees do, to launching giant mirrors into space, scientists are researching a wide variety of technologies to artificially slow global warming.

CO2 Injection

CO2 Injection

CO2 captured from coal-fired electric power plants may be injected for storage into porous layers of rock and sand deep underground.

CO2 Capture

CO2 Capture

In coal-burning power plants, CO2 can be captured for transport to storage sites.

CO2 Capture and Sequestration

CO2 Capture and Sequestration

CO2 may be separated from other gases at coal-fired electric power plants and transported by pipeline to suitable storage sites.

CO2 Storage Areas

CO2 Storage Areas

The United States has many areas, shown in pink, where geological formations are likely to be suitable for long-term carbon dioxide storage.
