中國海油集團(tuán)6月1日宣布，我國海上首個(gè)百萬噸級(jí)二氧化碳封存工程在南海東部海域正式投用，累計(jì)封存量將超150萬噸，相當(dāng)于植樹近1400萬棵。

China's first offshore million-tonne carbon storage project was put into operation on Thursday in the South China Sea, according to the China National Offshore Oil Corporation (CNOOC). The project is designed to store a total of more than 1.5 million tonnes of carbon dioxide (CO2), which is equivalent to planting nearly 14 million trees, according to the company.

【知識(shí)點(diǎn)】

“海上碳封存”，全稱為“海上二氧化碳地質(zhì)封存”，二氧化碳封存是減少大氣中二氧化碳濃度的有效方法之一。首先是要找到合適的存儲(chǔ)位置。位置選好后，就要通過鉆井建立一條往“碗”里輸二氧化碳的通道。最后海洋石油專家們創(chuàng)新性地為注氣管柱加裝了光纖監(jiān)測(cè)裝置，每隔一米就有一個(gè)監(jiān)測(cè)點(diǎn)，就像數(shù)千只敏銳的眼睛，在看不見摸不著的幾千米井下無死角觀察注氣管柱是否存在泄漏。二氧化碳注入地層后，大部分將被頂部的蓋層永久蓋住，同時(shí)一部分被地層孔隙捕獲，一部分慢慢溶解在地層水中，還有一部分與巖石和地層水反應(yīng)生成碳酸鹽礦物。

中國海域地殼穩(wěn)定性好、沉積盆地分布廣、地層厚度大、構(gòu)造地層圈閉多，具備封存二氧化碳的良好地質(zhì)條件，封存潛力達(dá)2.58萬億噸。6月1日，我國首個(gè)百萬噸級(jí)海上碳封存示范工程——恩平15-1油田碳封存示范工程在珠江口海域正式投用。這標(biāo)志著我國初步形成了海上二氧化碳注入、封存和監(jiān)測(cè)的全套鉆完井技術(shù)和裝備體系，填補(bǔ)了我國海上二氧化碳封存技術(shù)的空白。

A green and low-carbon economy and society are crucial to high-quality development. We must work faster to adjust and improve the industrial structure, the energy mix, and the composition of the transportation sector. We will implement a comprehensive conservation strategy, conserve resources of all types and use them efficiently, and move faster to put in place a system for recycling waste and used materials. Fiscal, taxation, financial, investment, and pricing policies and systems of standards will be improved to support green development. We will boost green and low-carbon industries and improve the system for market-based allocation of resources and environmental factors. We will accelerate the R&D, promotion, and application of advanced energy-saving and carbon emission reduction technologies, encourage green consumption, and promote green and low-carbon ways of production and life.

——2022年10月16日，習(xí)近平在中國共產(chǎn)黨第二十次全國代表大會(huì)上的報(bào)告

實(shí)現(xiàn)碳達(dá)峰碳中和是中國高質(zhì)量發(fā)展的內(nèi)在要求，也是中國對(duì)國際社會(huì)的莊嚴(yán)承諾。中國將踐信守諾、堅(jiān)定推進(jìn)，已發(fā)布《2030年前碳達(dá)峰行動(dòng)方案》，還將陸續(xù)發(fā)布能源、工業(yè)、建筑等領(lǐng)域具體實(shí)施方案。中國已建成全球規(guī)模最大的碳市場(chǎng)和清潔發(fā)電體系，可再生能源裝機(jī)容量超10億千瓦，1億千瓦大型風(fēng)電光伏基地已有序開工建設(shè)。

Achieving carbon peak and carbon neutrality are the intrinsic requirements of China's own high-quality development and a solemn pledge to the international community. China will honor its word and keep working toward its goal. We have unveiled an Action Plan for Carbon Dioxide Peaking Before 2030, to be followed by implementation plans for specific sectors such as energy, industry and construction. China now has the world's biggest carbon market and biggest clean power generation system: the installed capacity of renewable energy has exceeded one billion kilowatts, and the construction of wind and photovoltaic power stations with a total installed capacity of 100 million kilowatts is well under way.
