CARBON CAPTURE AND STORAGE

Carbon capture and storage

Introduction

Fossil Fuels: Carbon Capture and Storage

Despite efforts to switch to clean energy, coal will be part of our future, at least in the coming decades. It's cheap, abundant and we know how to use it: in the short term, coal is the safest way to satisfy the appetite for electricity in the world today. But as the combustion of coal is a dirty business that pollutes the atmosphere with CO 2 and other compounds under investigation to find alternative systems.

Carbon dioxide (CO 2 ) Is one of the greenhouse gases that contributes further climate change caused by man and atmospheric concentrations CO 2 now have a level three times higher than levels preindustrial (in 1850). To avoid catastrophic climate change we need to keep average increase in global temperatures below 2C and stop further growth emissions of greenhouse gases within the next ten to 15 years, get reduced by half by mid-century. There is much speculation about the potential of carbon capture and storage (CCS) how technology can be a solution to mitigate climate change but this technology is still developing. Although the number of pilot projects is increasing 1 The CCS will not begin in earnest before 2020 and probably will not become commercially viable as an effective option to mitigate possible until 2030

The carbon dioxide (CO 2) is a greenhouse gas that occurs naturally in the atmosphere . Human activities like burning fossil fuels and other processes, significantly increasing its concentration in the atmosphere contributing to global warming.

The capture and storage of CO 2 (CAC) may limit atmospheric carbon emissions resulting from human activities. This technique involves capturing the CO 2 produced in power plants or industrial plants, and then stored for a long period of time, either in geological formations underground, in oceans or other materials. Not to be confused with carbon sequestration, which involves cutting the carbon in the atmosphere by natural processes of forest growth

One way to make coal a cleaner is through carbon capture and storage, or CCS for short English (Carbon Capture and Storage). Under this method, which can be applied in coal plants as in natural gas, CO 2 is captured before it escapes into the atmosphere, it becomes a liquid and injected deep under the ground.

The carbon capture and storage (CCS)

Practical

The CCS technology can be used with common fuels-coal and natural gas used in many parts of the world. In fact, the United States, Russia, China and India, four of the most energy-intensive countries in the world, have approximately 67% of coal reserves in the world.

Reduces CO 2

CCS technologies reduce CO 2 emissions to the atmosphere, but do not solve all environmental problems associated with coal combustion.

Works

The CCS has been tested and improved in various industrial operations worldwide.

Expensive

The coal-fired power plants adapted to CCS are not as efficient as normal. Build and operate these plants is also expensive, but the electricity generated by them can be cheaper than that produced by ...
