South Africa hopes that every coal-fired power plant will have carbon capture systems
Thread Content
According to foreign media reports, South African officials recently said that they want carbon capture devices to be installed mandatorily in all coal-fired power plants and gasification facilities. This move is part of the global efforts to address climate change and build a low-carbon economy. South Africa is one of the major greenhouse gas emitters, with about 90% of its electricity coming from coal. The Environment Minister said that CCS (carbon capture plants) must be installed mandatorily in all new power plants from now on. There are currently no commercially operational CCS power plants in the world; only a dozen or so countries, such as the United States, the United Kingdom, Canada, and Norway, have committed to testing this technology on a commercial scale. These model power plants are expected to begin operating as early as 2012-2014. The official said that power plants without carbon capture devices will not be approved, and Africa’s rapidly growing economy will result in greenhouse gas emissions of 550 million tons by 2020. In other places, they will change the situation dominated by coal, but they will still rely on it, albeit clean coal. It is reported that harmful greenhouse gas emissions have raised Earth’s temperature, causing disasters for thousands of people who face famine, floods, and diseases, primarily in developing countries. CCS technology can capture and store harmful gases emitted by coal-fired power plants. The official said that South Africa needs to develop a low-carbon economy to enhance its global competitiveness, and diversify its energy sources such as nuclear energy and new renewable energies in order to alleviate the country’s electricity shortages. He said that investing 1% in mitigating GDP can save more than 5% of GDP. The official also said that South Africa needs to significantly raise carbon taxes by 2050, but given the country’s poor starting point, promoting a low-carbon economy would mean mass unemployment.
What is carbon capture? ? ? ;P ;P Do you know about the law of conservation of energy? Without C being converted to CO2, where does the energy come from? ? ? These are just the opinions of some idiots and amateurs; those of us with a degree in chemical engineering shouldn’t get involved in this nonsense
To be precise, it should be called carbon dioxide capture and storage (CCS, CO2 Capture & Storage or CO2 Capture & Sequestration). If such emission reduction requirements are indeed implemented in the future, it will mean a complete transformation of the thermal power generation industry. Upstairs, let’s discuss issues in a more calm manner, and try to understand more about the technical terms used. There is a reasonable side to every topic that the industry is paying attention to; it can be discussed, but it shouldn’t be dismissed outright, right?
In China’s coal chemical industry, CCS is currently only being implemented by Shenhua. This project is a collaboration with West Virginia University and the Lawrence Livermore National Laboratory in the United States; it is aimed at capturing and storing CO2 from Shenhua’s Ordos coal-to-oil plant. Construction is expected to begin next year, with the goal of purifying the CO2 produced by the plant to over 95% purity before injecting it underground through pipelines. However, CNPC has already begun using CO2 to improve oil recovery rates, namely EOR, near Liaoning. CNCG has also begun to use CO2 to enhance coalbed methane abroad.
