“carbon Capture And Storage: Mitigating Emissions From Gas-powered Plants”

“carbon Capture And Storage: Mitigating Emissions From Gas-powered Plants” – All of the emission pathways in the IPCC’s Special Report on Global Warming will require removing large amounts of CO2 from the atmosphere through carbon sequestration to achieve zero emissions. Carbon capture, use and storage (CCUS) is the process of capturing carbon dioxide (CO2) emissions from fossil energy production and industrial processes for storage deep underground or for reuse.

Countries need to implement zero-carbon and negative-carbon technologies to capture 90 Gt of CO2 by 2050 to meet the goals of the Paris Climate Agreement and implement the 2030 Agenda for Sustainable Development.

Fossil fuels are likely to continue to play an important role in the short to medium term. Today, about 80% of the energy distribution in the region is based on fossil fuels. Many countries across the region benefit from fossil fuel energy. Coal, oil and gas remain vital to their energy security and economic well-being.

Science Speaks: Carbon Capture

Carbon neutrality will therefore require the rapid deployment of carbon capture, use and storage (CCUS) technologies to bridge the gap until innovative next-generation technologies with low, zero or negative carbon emissions are commercialized.

Five UN regional commissions are joining forces to find solutions to climate change and on 24 September 2021 participated in the High Level Dialogue (HLD) on Energy to discuss the importance of carbon sequestration in achieving carbon neutrality and the 2030 Agenda for Sustainable Development.

Carbon capture and storage, key to mitigating climate change: more than 60% of electricity in 56 Member States is produced from fossil fuels, so CCS is essential to meet climate targets. Scott Foster, Sustainable Energy Director L’AEGFI Commodities 2015 Special Issue (page 16) Carbon Capture and Storage [CCS]: A promising technology to reduce CO2 emissions from power plants and industrial processes:

Carbon capture and storage (CCS) is a rapidly developing technology that has gained attention as a potential solution for reducing greenhouse gas emissions, especially carbon dioxide (CO2), from power plants and industrial processes. CCS involves capturing CO2 emissions from these sources and storing them underground or elsewhere to prevent them from escaping into the atmosphere. This article provides an overview of CCS, including its principles, technologies, and potential benefits and challenges. The hypothesis is that CCS can significantly contribute to global efforts to mitigate climate change by reducing CO2 emissions from major point sources, and that it can be a viable and necessary technology to achieve carbon neutrality in certain industries.

Co2 Capture & Storage

Climate change caused by anthropogenic emissions of greenhouse gases, mainly CO2, has become one of the most pressing global challenges. Power plants and industrial processes are the main sources of CO2 emissions, accounting for a significant proportion of global greenhouse gas emissions. In recent years, CCS has emerged as a promising technology for reducing these emissions by capturing CO2 from these sources and storing it underground or elsewhere, preventing it from escaping into the atmosphere.

CCS involves three main steps: capture, transport and storage. The capture phase involves capturing CO2 emissions from power plants or industrial processes before they are released into the atmosphere. There are three main methods of CO2 capture: post-combustion, pre-combustion and oxy-combustion. Post-combustion capture involves the capture of CO2 from flue gases after burning fossil fuels. Pre-combustion capture involves converting the fossil fuel into a mixture of hydrogen and carbon monoxide gas and then separating the CO2 from that gas mixture. Oxyfuel combustion involves the combustion of fossil fuels in an oxygen-rich environment, resulting in flue gases consisting primarily of CO2 and water vapor, facilitating the capture of CO2.

Once captured, the CO2 must be transported to a suitable storage location. This may include pipelines, ships or other methods of transportation depending on the distance between the receiving site and the storage site. Finally, the CO2 is injected into suitable geological formations, such as deep saline aquifers, depleted oil and gas reservoirs, or unextractable coal seams, where it is safely stored underground, preventing it from escaping into the atmosphere.

There are also emerging technologies for direct air capture (DAC), which involve capturing CO2 directly from ambient air. DAC can remove CO2 emissions from the atmosphere, not only from point sources, and could be used in conjunction with CCS to achieve negative emissions.

Numerous studies and research* have highlighted the potential benefits of CCS as a viable option for reducing CO2 emissions and mitigating climate change. One of the significant advantages of CCS is its ability to significantly reduce CO2 emissions from major point sources such as coal-fired power plants and energy-intensive industrial processes. According to the International Energy Agency (IEA), CCS could help reduce global CO2 emissions by around 15% by 2050.

CCS can also ensure the continued use of fossil fuels, which are still the main source of energy for many countries, while reducing their carbon footprint. It can be retrofitted to existing power plants, making it a viable option for reducing emissions from existing infrastructure. In addition, CCS has the potential to create new economic opportunities, including job creation, infrastructure investment and the development of new technologies.

In addition, CCS can play a critical role in decarbonizing hard-to-emission industries such as cement, steel and chemicals, where other low-carbon alternatives are limited or expensive. These industries are responsible for a significant portion of global CO2 emissions and are considered difficult to decarbonize due to their dependence on fossil fuels and high-temperature industrial processes. CCS has the potential to capture CO2 emissions from these industries and help achieve significant emissions reductions, contributing to global efforts to mitigate climate change.

In addition, CCS can also improve the environmental performance of other industries, such as natural gas processing and bioenergy production, by capturing CO2 emissions from these processes and preventing their release into the atmosphere. This can help these industries move to more sustainable practices and reduce their carbon footprint.

Ccs Explained: Storage

There is also evidence that CCS can help improve air quality by capturing other pollutants, such as sulfur dioxide, nitrogen oxides and particulate matter, which are harmful to human health and the environment, along with CO2. By reducing these pollutants, CCS can contribute to improving air quality and human well-being.

Despite its potential benefits, CCS also faces a number of challenges and considerations that need to be addressed in order to be successfully implemented on a large scale. One of the main challenges is the cost associated with implementing CCS, including capture, transport and storage processes. CCS can be capital intensive and can increase the cost of electricity and industrial production. However, the cost of CCS has decreased over the years, and efforts are ongoing to further reduce costs through technological advances and economies of scale.

Another challenge is identifying and characterizing suitable storage sites. Suitable geological formations for CO2 storage must be identified, assessed and monitored to ensure their long-term integrity and prevent CO2 leakage. Public acceptance and regulatory frameworks are also important factors to consider, as they can affect the deployment of CCS projects.

In addition, there are concerns about the potential environmental impacts of CCS, such as the energy required for the capture process, the potential leakage of CO2 from storage sites, and the long-term monitoring and liability associated with stored CO2. These concerns need to be carefully addressed through comprehensive environmental assessments and appropriate regulations to ensure the safety and sustainability of CCS implementation.

Carbon Capture, Use And Storage (ccus)

CCS is a promising technology that can significantly contribute to global efforts to mitigate climate change by capturing CO2 emissions from power plants and industrial processes and storing them underground or elsewhere. This can ensure the continued use of fossil fuels while reducing their carbon footprint, and can play a vital role in decarbonising hard-to-emission industries. However, there are some challenges and considerations that need to be addressed, including cost, identification of the storage site, public acceptance, and environmental impact.

Based on evidence from reliable publicly available sources, CCS has shown promise as a viable and necessary technology for achieving carbon neutrality in certain sectors and mitigating climate change. Continued research, development and implementation of CCS, as well as appropriate regulation and public engagement, can help realize its full potential, contributing to global efforts to address climate change and transition to a low-carbon economy.
