According to this article”Carbon Catch and Storage area as a Strategy to Mitigate Climate Change”, local climate warming and greenhouse effect have become critical challenges for global environment. Climate modify is one of the most complex issues facing all of us today. It involves many science, economics, society, politics and ethical and moral questions which is a global problem, felt upon local scales, that will be around for decades and centuries to come. (nasa, no date). Especially in a few special domains, such as electrical power plants, chemical factories, exploration plants, a defieicency of carbon dioxide emission has become the concentrate of the peoples attention. Through the analysis of the geochemical cycle of carbon, it could be clearly regarded that carbon dioxide is changed and recycled in the natural cycle, which includes long-term and short-term techniques. In order to mitigate carbon dioxide exhausts, this article deeply discusses the techniques of carbon dioxide capture and separation and comprehensive evaluate the way of co2 storage. The first is the record and storage of co2, which involves different processes such as pre-combustion, post-combustion and oxyfuel combustion(Leung ain al., 2014). Pre-combustion get usually arises in coal or natural gas, and post-combustion carbon get (PCC) technology is a comparatively mature technology in power plant systems. Oxygen fuel burning is also employed in various power plants. In order to store carbon dioxide, the carbon dioxide is segregated after get. The main methods are consumption, adsorption and membrane separating. The commonly used solvent to get absorption is definitely the monoethanolamine (MEA). Adsorption usually are attached to the area of blotting during Co2 adsorption method. The last method to separate carbon is to use membrane adsorption with high carbon dioxide permeability and selectivity.
The separated carbon can be stored in physical and biological ways. Physical carbon safe-keeping methods and technologies generally store co2 in different geological structures, such as abandoned coal and oil reservoirs, deep-sea storage, and saline water supplies. Photosynthesis takes on a key part in the co2 cycle, therefore afforestation not simply stores carbon dioxide but as well increases the capacity to sequester it. Sea carbon sequestration is also a Giant container to storage the carbon basing on photosynthesis. At present, you will find pilot tests to test if this method is effective. Microalgae and cyanobacteria possess high carbon sequestration capacity also basing about photosynthesis, both these styles which cost too much.
In conclusion, every carbon capture and storage area method reveals promise pertaining to climate minimization, but there are many limitations, just like cost and immature technology and so on. Physical methods are relatively immaturity and play a small position in some sectors. Lack of authorities incentive device, high cost operation. Blue bacterias and algae are also becoming studied. Carbon sequestrationg are definitely the advantage methods in order to mitigate climate alter and reduce green house gases exhausts, although the limitations of technology now.

The purpose for choosing the text
I choose this information as my personal reading log, I think that the main reason is related to my major and the stressing environment during my hometown. My own undergraduate major is environmental engineering, therefore i want to know even more about the relevant knowledge of my own major. When I saw the topic, I believed that I will be very interested in this kind of topic. As for the environment of my hometown, I remember once i was a kid, my home town was almost all green mountain range and marine environments of characteristics, with gorgeous scenery and fresh air. Currently, people squander all the all-natural resources and create a large number of industries, power plants and the environment becomes worse. Daily, we can see the haze and could will no longer see the blue sky and white clouds as a child. Therefore , I think the planet problem is a very serious matter, it is associated with peoples living environment and global climate warming, I eagerly hope to have a dependable and effective method or perhaps technology to mitigate local climate problem. That is why I chose this article.
Indication and analysis of the author’s position
In this article, the authors are informing a large amount of references and seriously examined various imformation. By comparing the advantages and drawbacks of various co2 capture and storage methods, author have got clearly displayed the current successful method for excuse climate transform. The article is meant for those who are interesting in global climate alter issues plus the students who also are major in environment and the environmental scientists or professors plus some governmental employees.
The author is a Bachelor of Technology, specializing in chemical substance materials, and has some exploration in this area. Due to the fact that the article is dependent on collected research there are extremely little opinions in it. The authors present a balanced attitude in summary with the physical and biological strategies of carbon storage space, and respectively compare the huge benefits and disadvantages with the different strategies. This article is extremely convincing to me, although there are many limitations and technical immaturities in these strategies to mitigate weather change, these types of efforts are most aimed at mitigating global local climate change. It really is no doult that the co2 capture and storage is a valid way to mitigate climate modify. In my opinion if the government and relevant departments can pay focus on this part of research, inspire and invest in some technological institutions, I believe that it will have greater improvement in this regard.
Mention of the additional analysis (optional)
In the record of the ESTE Strategy Group, the UNs climate -panel has published the third part of its long-awaited report- upon strategies for minimization. The organization propose that we should minimize the problem of climate heating and require us to work with new technology, new energy sources, and change peoples behaviors to accomplish energy conservation. In the case of new energy, that generally identifies renewable energy, which includes wind, solar power, geothermal, hydroelectric or indivisible. But there are plenty of limitations to technologies. Nevertheless , fossil fuels continue to account for 80 percent of all strength. Faced with serious challenges, this article also says carbon sequestration capture technology, which can help reduce some of the pressure. Although CCS theoretically restrictions the amount of carbon that gets into the atmosphere, the amount of carbon does not decrease, but only in one kind. Therefore , power such as solar power is the key to solving this kind of challenge.
