It is considered as a great accomplishment for china’s first carbon capture. Huaneng, the company running it, sells its carbon dioxide to beverage firms. This carbon dioxide is subsequently added into drinks for creating more bubbles.
Huaneng’s method to capture carbon is utilizing solvents to resolve the carbon dioxide emitted from coal combustion. This methodology can be applied to the most power stations, which are coal-fired. Excluding the expense on constructions, this technology enables the companies cover the operation cost by earning profit from sales to beverage supplier.
However, ascribed to high cost of the carbon capture and storage, this technology for globally reducing carbon dioxide emission is still restricted. China now is catching up for its late coming for carbon capture and storage and playing an important part. Facilities for carbon capture and storage are set up quickly, because of Olympics coming. Besides, Huaneng receives technical support from other countries but refuses the financial offer because researchers think the independence is crucial for further development of this project.
There are still some challenges countered during the project. The Solvent can be improved to prevent itself evaporating away when it is heated in order to release the carbon dioxide. Besides, when other power stations emit fuel gases which contain more impurities, the technology of this carbon capture and storage need to be modified. It is essential to join the post-combustion capture and integrated gasification combined cycle these two processing technology together. China has spent considerable money on it, but till now there is no this kind of facilities introduced in China.
Huaneng now is seeking for potential partner for future carbon storage, but no exact result is released. Due to large carbon dioxide emission, low-cost facilities and latest technology embraced, China is now expected to be the world leader in carbon capture and storage.

The use of articles
One of the most common grammar mistakes is the misuse of articles. Articles can be divided into two groups. One is definite article, the, and the other is indefinite, a and an. One type of mistake is using the wrong article. For instance, “I am the student”. The sentence is wrong because here student only refers to a general concept of job. Thus the correct one should be “I am a student”. Another type of mistake is misusing a and an. an is only used before vowel sounds. Take note that it is vowel sounds but not vowel letters. For instance, the two correct sentences should be “It is an unusual book” and “The aim of a university should be the advancement of learning”, though both articles are before letter u. The other one is omission of articles, or called zero article. Articles are not added before names of nationalities, sports and academic subjects. However, some phrases need articles. For example, when we talk about playing a specific musical instrument, the should be used before the noun.
Here is an exercise for article use.
Fill in the blanks with a, an, the or zero article.
