CO2 released when burning fossil fuels leads to global warming
Turn carbon capture into stone and store underground!
- In Iceland, scientists turned carbon into stone by pumping a power plant’s carbon dioxide into underground basalt and mixed them with water. The process chemically solidified the carbon dioxide and changed the basalt and CO2 into a chalk like substance.
- The solidifying process takes 2 years, whereas it was originally assumed to take decades.
- The solidification resolves the risk that carbon stored underground as gas or slurry could accidentally be released into the atmosphere.
- Its currently unclear whether the process could work with many types of basalt or saltwater as opposed to freshwater
- Governments trying to meet CO2 cap commitments
- Power plants trying to limit CO2 due to regulations or cap and trade limits/incentives
- Citizens who benefit from avoiding the impacts of global warming
- Coastal cities/regions and other high risk localities that have to plan and pay for warming mitigation and adaption
First 3 steps for deployment:
- Additional studies of types of basalt and water required for the reaction (including testing factors that affect the duration of the reaction)
- Analysis of potential geographic locations and power plants that have the proper basalt formations and could make use of the technology
- Cost analysis and funding models to determine how much the technology will cost to use and which stakeholders should contribute to the costs
