The Future of CO2 Capture and Storage
2 min read
Capturing and storing CO2 help reduce greenhouse gas emissions. In addition to sufficiency, and the development of renewable energies, they offer solutions to combat . This educational video explains how these rapidly evolving technologies work.
The Future of CO2 Capture and Storage
Capturing and storing CO2 helps reduce greenhouse gas emissions and thus slow down global warming.
The CO2 can then be used in several ways:
- Utilization without conversion
Example: beverage carbonation. - Utilization through reaction with another chemical compound
Example: polycarbonates and polymethanes. - Biological utilization through
Example: microalgae cultivation for biofuels.
Capture of CO2
CO2 emissions in plants and factories are caused by the combustion of fossil fuels. There are currently 3 methods to isolate from the rest of the flue gas:
– Post-combustion – Pre-combustion – Oxy-combustion
Some require a lot of energy and are very expensive. Other methods must therefore be developed.
Storage of CO2
The CO2 is compressed into a liquid state. It is transported via pipeline, truck or ship then stored in 1 of 3 ways:
- natural reservoir
- artificial reservoir
- into an oil field
These can also be costly and storage capacity can be low.
Challenges of CO2
Develop and improve capture, transportation, storage and utilization methods in the hope of increasing the amount of CO2 treated from 30 million metric tons per year in 2017 to 10 billion in 2050.
Summary:
- Capturing and storing CO2 is one way of combating global warming.
- Several capture, transportation, storage and utilization methods already exist.
- Challenges: improve these methods, identify new ones and, above all, step up development to treat an increasing amount of CO2
