Most carbon capture projects around the world are anxious!

An analysis shows that the performance of several largest carbon capture and sealing (CCS) projects in the world is obviously not good -the carbon dioxide capture of some of these projects is only half of the promise.

CCS is deemed to be an important tool for climate change by institutions such as the Intergovernmental Climate Change of the United Nations. This technology will be strongly supported in the new climate bill promulgated by the US government, and other countries are also encouraging CCS, including Norway and Britain.

A report released on September 1 analyzes the performance of the 13 flagship CCS programs around the world, and it is found that carbon dioxide captured by most countries is far lower than expected.

The report states that ExxonMobil is located in the Labarge factory in Shutxi, Wyoming, USA, and its carbon capture performance is about 36%behind. The world's only large -scale power station with CCS technology -the "border dam" in Saskatchewan, Canada, the caught carbon is about 50%less than the carbon plan. Chevron is located in the Gorgon natural gas project in Western Australia. The first five years of capture is about 50%less than the plan.

The report also mentioned two failed projects, including the Kenper Coal CCS project in Mississippi, the project, which was delayed for a long time and eventually abandoned construction in 2017.

The Bruce Robertson of the Australian Energy Economic and Financial Analysis Institute (IEEFA) said: "Is CCS solve the method of climate? I would not say. Usually, it did not exert its expectations."

The technology of CCS can be traced back to the 1970s. In many cases, it is used to extract more oil from the reservoir instead of long -term capture of carbon dioxide to curb climate change. Robertson added that the performance of these plans was not because of lack of financial or engineering resources. In fact, the Gorgon project alone costs 3.1 billion Australian dollars.

From a more positive perspective, the report found that Norway's Sleipner and Snohvit CCS projects have achieved success, which is largely due to the unique business and regulatory environment of the country. Robertson admits that CCS may play a role in the heavy industry that is difficult to prevent carbon emissions in the future, such as cement manufacturing.

Stuart Haszeldine of the University of Edinburgh said that IEEFA's report is comprehensive, but claiming that CCS does not work "too simple". He said that one reason for the poor performance of the CCS project is not the technology itself, but the lack of market incentive mechanism for storing carbon dioxide and good supervision. Haszeldine said: "When the rules are correct, CCS does work."

A Chevron spokesman said: "This scale innovation is not without challenges, but technology is feasible." A spokesman for ExxonMobil said: "The carbon dioxide captured by the labarge factory is better than any other in the world than any other world. There are many factories. "
