Carbon emission reduction: the United States relies on CCS technology

in order to actively respond to climate change and ensure the leading position of clean energy in the world, the United States attaches great importance to the development of carbon dioxide capture and storage (CCS) technology, provides strong support for capture, storage, utilization and other links in CCS projects, and strives to promote the safety and feasibility study of carbon storage. The clean coal technology report recently released by the government points out that the United States will successfully achieve the development goal of CCS projects, and the wide promotion of CCS is just around the corner

make huge investments to ensure leading technology

according to the latest statistics of the International Energy Agency, the world will invest US $1.3 trillion and deploy 3400 CCS projects by 2050. CCS's share of emission reduction will reach 19%, becoming the single technology with the largest contribution to emission reduction. To ensure the leading position of the United States in CCS technology, at the beginning of this year, the United States established a CCS working group jointly responsible for the Department of energy and the environmental protection agency to vigorously develop carbon dioxide capture, compression, transportation and storage technologies. On August 12, the working group provided President Obama with the clean coal project development report, which pointed out that promoting the clean coal technology represented by CCS can fundamentally achieve the government's clean energy goals and provide a large number of employment opportunities. As it can play an important role in reducing greenhouse gas emissions, CCS can help the United States continue to use coal and other domestic abundant fossil energy, and help the United States maintain its global leadership in clean energy

this report, which gathered the opinions of 14 federal agencies and departments, as well as hundreds of stakeholders and CCS experts, shows that it is completely feasible for the United States to deploy CCS on a large scale in the future, and the existing technologies, laws, systems and other conditions will not become a fundamental obstacle to the development of CCS. The report emphasizes that the key to the development of CCS is to ensure the carbon trading price. A reasonable price will generate a huge market driving force for the recent CCS demonstration projects and ensure the economic benefits of the full deployment of CCS

in recent years, the U.S. government has made unprecedented investment in CCS. In 2008, the U.S. Department of energy invested nearly $500million to develop CCS technology, which increased to nearly $700million in 2009. The "American Recovery and Reinvestment Act" allocated $3.4 billion for CCS technology. The report of the CCS working group shows that so far, the Ministry of energy has approved nearly US $4billion of national funds for CCS demonstration projects, and has attracted more than US $700million of private investment. These investments will lay a solid foundation for the United States to achieve the goal of extensive deployment of advanced CCS projects within 10 years. According to the plan, 5 ~ 10 CCS commercial demonstration projects will be operated in the United States before 2016, and economically feasible CCS projects will be widely deployed in the United States in 2020

underground storage potential 3.5 trillion tons

the safety and reliability of underground storage of carbon dioxide have been controversial. The United States has conducted many years of research on the feasibility of underground storage, and has increased financial support. It has carried out detailed research on carbon storage under different conditions through a number of demonstration projects

on August 11, US Secretary of Energy Steven Chu announced that he would provide us $21.3 million within three years to fund 15 projects to develop underground carbon dioxide storage technology, aiming to store carbon dioxide safely and economically. These investments will support the development of CCS technology and infrastructure to ensure large-scale carbon dioxide storage in different geological formations. The 15 projects selected by the Ministry of energy will improve a series of key technologies, strive to solve problems including formation injection, storage capacity, plume migration, etc., study problems such as isolation and leakage prevention through rock cover and other mechanisms, and study the application effect of depleted oil and gas reservoirs, deep salt formations, non exploitable coal beds, oil and gas rich shale and basalt in carbon dioxide storage

the U.S. Department of energy believes that the underground storage of carbon dioxide has great potential. According to the carbon dioxide storage map of the United States and Canada released by the national energy technology laboratory, the underground storage potential of carbon dioxide alone has reached 3.5 trillion tons. Based on the annual emission of 3.2 billion tons of carbon dioxide, the strata of the United States and Canada can store 1100. This is because of the carbon dioxide emissions during the whole mold opening trip during the mold installation

Lisa Jackson, director of the US Environmental Protection Agency, said that the environmental protection agency is actively developing China's slightly backward carbon storage technology, reducing the uncertainty of early projects, and improving the laws and regulations to ensure the safe and effective use of the technology. She firmly believes that once CCS technology is mature, it will open up new fields for the United States in reducing greenhouse gas emissions and creating jobs

new approach to carbon reduction through reuse

Chu said that carbon dioxide capture and reuse can help effectively reduce carbon emissions in areas that are not suitable for long-term underground storage of carbon dioxide. It is an important part of CCS technology vigorously developed by the United States. In the future, a large number of power generation and other industrial projects using fossil fuels as energy sources will be equipped with this carbon dioxide capture and utilization technology to meet the requirements of carbon emission regulations

in July this year, the US Department of Energy announced that it would support six industrial carbon dioxide capture and conversion projects to convert industrial carbon dioxide emissions into products such as fuel, plastics, cement and fertilizer. These projects will receive US $106million from the American Recovery and Reinvestment Act and US $156million in private investment. In the six carbon dioxide capture and conversion projects, Alcoa uses enzyme catalysts to efficiently convert the carbon dioxide from smelting flue gas into soluble bicarbonate and carbonate, and then uses carbonate products as building fillers, such as soil conditioner and green fertilizer; Novomer will develop carbon dioxide production technology for polycarbonate plastics; Touchstone will test the algae planting technology, which can use the carbon dioxide emitted by coal to cultivate algae, which can then be converted into biofuels such as methane and other high value-added products; Phycal will use carbon dioxide to produce microalgae biomass fuel. How to do strength test with ceramics? Used for power generation or processing into alternative fuels such as jet fuel and biodiesel; Skyonic and Calera will use the carbonate produced by carbon dioxide to produce building materials, etc
