CCUS technology is a new development trend of Carbon Capture and Storage (CCS) technology, that is, Carbon dioxide emitted in the production process is purified and then put into the new production process, which can be recycled instead of simply stored.
Compared with CCS, it can recycle carbon dioxide, generate economic benefits, and be more practical.So, for this new type of energy, which can not only recycle, but also recycle carbon dioxide resources, to generate new economic benefits, why is the scale of development so limited?
I. High energy consumption
We know the conditions of the carbon dioxide is need burning, is currently the most widely industrial use energy supplies of coal, coal combustion produces ability, will release a large amount of carbon dioxide, but because of the main components of the coal is not only the C, there is also the composition such as O, S, N, makes carbon dioxide purification become one of the additional energy consumption process, many enterprises because of the trouble, The application of CCUS technology is abandoned.
2，High cost
CCUS technology is divided into two stages: carbon dioxide capture and carbon dioxide storage. The complex process leads to excessive investment in the early stage.
3. High uncertainty
Driven by the goal of "carbon neutrality", the technology has become a topic that must be understood in the industry. However, the lack of incentives from national policies and difficulties in industrial chain coordination make many enterprises unable to judge whether the technology is feasible, and no one wants to lose the money they have invested.
China's Agenda 21 Management Center and China Society for Sustainable Development have recently hosted two CCUS Young Scholars salons and China CCUS Demonstration Project Exchange seminars. In the long run, it's a shortage of talent. In the near term, it needs a big push from the relevant departments.
In 2011, the first version of the CCUS Technology Development Roadmap prepared by the Ministry of Science and Technology positioned CCUS as a "strategic reserve technology" for large-scale low-carbon use of fossil energy. However, CCUS technology is "indispensable" under the goal of "carbon neutrality". CCUS technology is highly recognized by the Climate Change Working Committee of the Institute for Sustainable Development. They believe that CCUS will play four important roles: 1. It is an important technology choice for remaining fossil energy net zero emissions under carbon neutrality; 2. It is an important competitive technical means for thermal power industry; 3. It is one of the few feasible technical solutions to achieve net zero emissions in industries that are difficult to reduce emissions, such as steel and cement; 4. It is the main source of green carbon for the future energy system and chemical process flow. At the same time, by 2060, some of the greenhouse gases that cannot be reduced need to be offset by carbon sinks and negative emission technologies. The negative emission technology coupled with CCUS and new energy is the technical guarantee to achieve carbon neutrality.
