01 Stringent Environment Regulation Many countries have imposed severe emission restrictions for power plants in response to air pollution and climate change concerns. Oxyfuel combustion technology assists power plants in meeting these regulations by lowering nitrogen oxide (NOx) generation and allowing for more effective carbon capture. The Industrial Emissions Directive in the European Union establishes emission limits for pollutants from ample combustion facilities, thereby encouraging the use of technologies such as oxyfuel combustion.Furthermore, implementing carbon pricing mechanisms, such as carbon taxes or cap-and-trade systems, encourages industries to decrease their carbon footprint. With the possibility of carbon capture, oxyfuel combustion becomes an appealing choice for businesses seeking to control their carbon obligations. On August 1, 2023, 74 carbon pricing schemes were operating worldwide. Carbon taxes or emissions trading schemes (ETS) are two possible strategies. The World Bank's Carbon Pricing Dashboard highlights the global momentum in implementing carbon pricing policies, which create economic incentives for adopting low-carbon technologies.Additionally, several regions have established renewable energy portfolio standards, requiring a particular percentage of electricity generation from renewable sources. California's Renewables Portfolio Standard (RPS) was established in 2002, and by 2030, renewable energy must account for 60% of the state's electrical supply. The program increases the state's load-serving organizations' need for renewable energy from RPS-certified facilities. Oxyfuel combustion can be combined with renewable energy technologies to increase power generation sustainability. As the world's attention on environmental sustainability grows, the oxyfuel combustion technology market trend is poised to contribute to a lower-carbon future.
01 High Cost The most significant capital investment in implementing oxyfuel combustion technology is the installation of oxygen separation machines, which are required to create an oxygen-enriched environment for combustion. The expenditures connected with designing, developing, and building these devices can be significant. The oxyfuel combustion technique is costly and energy-intensive, raising the price of electricity generated by oxyfuel plants from USD 66.8 to USD 123.7 per MWh. Additionally, retrofitting existing industrial facilities to support oxyfuel combustion can be costly. This could include changes to combustion systems, flue gas handling infrastructure, and the installation of carbon capture equipment. The Petra Nova project in Texas, USA, is one of the world's most significant post-combustion carbon capture and storage sites. Completed in 2017, the project involved retrofitting an existing coal-fired power plant with oxyfuel combustion technology and a carbon capture system. The project's entire cost topped USD1 billion, which included considerable investments in equipment, infrastructure, and technology development. In addition to the initial capital investment, continuous operational and maintenance costs are involved with maintaining oxygen separation units, carbon capture facilities, and other components of the oxyfuel combustion system. Thunder Said Energy says oxyfuel combustion costs between 6 and 8 cents per kilowatt hour.
