One of the most important issues of our day is climate change. Global warming is caused by rising atmospheric concentrations of carbon dioxide (CO2), which has dire effects on the world. Many tactics have been devised to counter this, and carbon capture technology is one of the most promising. This essay will define carbon capture, explain its operation, and offer data and examples from actual projects.
Carbon Capture: What Is It?
One way to lessen the quantity of CO2 emitted into the environment is by carbon capture, additionally referred to as carbon capture and storage (CCS). It is essential to the attempts to slow down climate change. With the use of this technology, CO2 emissions from industrial and power plant sources are prevented from entering the atmosphere. After being captured, the CO2 is either moved to storage facilities or put to other useful uses.
How is carbon capture carried out?
Three primary steps are involved in carbon capture:
- Capture: CO2 is now being held at the point of emission. The most popular techniques for this are oxyfuel combustion capture, pre-combustion, and post-combustion.
- Transport: The CO2 must be moved to a storage area once it has been captured. Usually, trucks, ships, pipelines, or even natural gas pipes are used for this.
- Storage: Deep underground geological formations such as saline aquifers or degradation of gas and oil reserves are used to inject the captured CO2. It is safely kept here, keeping it from escaping into space.
Real-World Information and Instances
- Norway’s Sleipner Project: One of the first initiatives involving carbon capture and storage is the Sleipner project. It started in 1996 and is still going strong today. During extraction, CO2 is captured by this natural gas facility and stored in a saline aquifer beneath the North Sea. It had held more than 16 million tons of CO2 by 2016.
- Boundary Dam (Canada): Located in Saskatchewan, Canada, the Boundary Dam power station is the first coal-fired power plant in the world to successfully incorporate carbon capture and storage. Since 2014, it has been collecting and storing CO2.
- Global Potential: By 2040, carbon capture and storage could help cut CO2 emissions worldwide by roughly 15%, in accordance with the International Energy Agency (IEA). It is therefore an essential tool in the fight against climate change.
- Use of Captured CO2: Captured CO2 can also be used in various industries. For instance, it’s used to carbonate soft drinks and can be utilized in enhanced oil recovery to extract more oil from existing wells.
To sum up, carbon capture technology is an essential instrument for reducing the effects of climate change. It is applicable to many different businesses and keeps CO2 emissions out of the atmosphere. Despite several difficulties, it has the potential to cut greenhouse gas emissions.
