A Review Based on Low- and High-Stream Global Carbon Capture and Storage (CCS) Technology and Implementation Strategy

Limits to Paris compatibility of CO2 capture and utilization

The current landscape of Carbon Capture and Storage (CCS) technologies is rapidly evolving, moving towards more cost-effective solutions to address the economic challenges associated with energy transition. Greenhouse gas emissions pose a significant threat to millions of people, as the global temperature continues to rise. Despite the close link between emissions and industrialization, many companies are actively engaged in developing high-performance, affordable CCS systems to reduce their carbon footprint without compromising their financial stability. As of early 2021, there were 24 operational commercial CCS and carbon capture and utilization (CCU) facilities worldwide, with the capacity to capture approximately 0.04 billion metric tons per annum (Gtpa) of CO2 emissions from energy and industrial processes. These facilities include natural gas processing plants, a coal power plant, chemical plants, hydrogen production facilities, and iron and steel plants. While some plants have ceased operations, 30 more are in various stages of development. Additionally, there are 16 small-scale pilot and demonstration plants currently in operation, with 19 in development and 24 already completed and closed. If all 30 commercial plants under development are completed, the capture capacity would increase to about 0.1 Gtpa. Notably, there are three operational commercial plants utilizing bioenergy with CCS (BECCS), with seven more in development. The current capture capacity of operational BECCS plants is relatively low, at 1.13 million metric tons per annum (Mtpa), but it could rise to 9.7 Mtpa if all the plants in development become operational. Furthermore, there are nine smaller-scale BECCS pilot and demonstration plants active, with six completed and four in various stages of development.2 There are several ways to capture CO2 and stabilize it under atmospheric conditions but the most studied systems commercially available are based on the formation of carbamate between CO2 and an amine in post combustion capture systems. First, the CCS systems can be divided in two main technological approaches, depending on the target application of such technology. There are direct air capture and industrially derived capture. Direct air capture, being the most ambitious and technological challenging approach, still requires plenty of work to deliver commercially scalable and economically viable solutions, as it accounts only for the 1% of total CCS technologies available. Currently, there are two plants using Direct air carbon capture and storage (DACCS), with one under development, in addition to 15 pilot and demonstration plants either in operation or in development; however, collectively, their capture capacities are quite limited. Capture technologies are at different levels of technological readiness (TRL), with some at TRL 1. Industrially derived capture is the most used one and can be further divided in three different technologies: Pre-Combustion Capture, Post-Combustion Capture and Oxy-fuel combustion capture. Post-combustion carbon dioxide (CO2) capture is mainly relevant to traditional natural gas and pulverized coal-fired (PC) power generation. In a typical PC power plant, fuel undergoes combustion with air in a boiler to produce steam, which then drives a turbine to generate electricity. The resulting boiler exhaust, or flue gas, primarily consists of nitrogen (N2) and CO2. The separation of CO2 from this flue gas stream poses significant challenges for several reasons: CO2 is present at a dilute concentration (typically 13 to 15 volume percent for PC power plants and 3 to 4 percent for natural gas-fired plants) and at low pressure (slightly above atmospheric), necessitating the treatment of a large volume of gas; trace impurities such as particulate matter, sulfur dioxide (SO2), and nitrogen oxides (NOx) in the flue gas can impair sorbents and reduce the efficiency of certain CO2 capture processes; CO2 is captured at low pressure, and compressing it from atmospheric to pipeline pressure (about 2,000 pounds per square inch absolute [psia]) will result in a substantial auxiliary power load on the overall power plant system.3

This research work investigates the feasibility and efficiency of implementing Carbon Capture and Storage (CCS) Technologies in Downstream Equipment such as in refining and processing, distribution and marketing, petrochemical production and retail sales as ways to mitigate greenhouse gas emissions. Considering the world is in urgent need to cut the emissions of greenhouse gases in order to deal with the challenge of climate change. Most mitigations have targeted carbon dioxide (CO₂), because it is the major agent in global warming. The research focuses on three primary CCS techniques: post-combustion capture, pre-combustion capture, and oxy-fuel combustion. These technologies are unique because they stand out as the only technologies that permit the continued use of fossil fuel powered sources while reducing the amount of CO₂ from these sources. Post-combustion method is best suited for retrofitting existing power plants, its challenges of energy and operation costs would be addressed if there is advancement in chemistry solvent, process efficiency and integration with renewable sources. Pre-combustion method Capture CO2 with 90% efficiency and produces hydrogen as a clean fuel, its viable for new-build plants. Oxy-fuel combustion simplifies CO₂ capture by producing a pure CO₂ stream, also ideal for newly installed facilities. This research also discovered CCS applications in enhancing oil recovery, industries decarbonization, and limiting emissions in sectors necessary for CCS. High costs, infrastructure requirements, and regulatory needs, are few challenges. Each technology fits different need, but their economic viability would be to balance the cost, efficiency and suitability to existing or new installed facilities

Low-carbon production of iron and steel: Technology options, economic assessment, and policy

Carbon capture and storage (CCS) facilities coupled to coal-fired power plants provide a climate change mitigation strategy that potentially permits the continued use of coal whilst reducing the carbon dioxide emissions. However, the still-high cost of CCS is one of the major obstacles, especially for developing countries. In this paper, we will assess techno-economic aspect of various carbon capture and storage technology in coal-fired power plants, including pre-combustion capture, post-combustion capture, oxy-combustion capture, as well as carbon storage. For various coal-fired power plants, integrated gasification combined cycle with pre-combustion capture has the highest potential to capture carbon dioxide with the lowest energy penalties and capital & operational costs, post-combustion capture can be retrofitted at relatively low cost to existing pulverized coal power plants and allows the combustion process to be kept relatively unchanged, and oxy-combustion capture is relatively immature at present. Although CCS has been accepted as clean development mechanism (CDM) project activities under the Kyoto Protocol, current carbon trading mechanism is inadequate to strongly promote investments on CCS facilities coupled to coal-fired power plants.

Carbon dioxide (CO2) is a major anthropogenic greenhouse gas. The atmospheric concentration of CO2 has increased from 280 ppm, in the mid-1800s, to about 407 ppm in 2017. Due to the global warming and climate change effect there have been worldwide efforts to control CO2 emission. Pre-combustion capture, post-combustion capture, oxy-fuel combustion, and chemical looping combustion are the technological options currently under consideration for capturing CO2 from combustion and gasification facilities. Carbon capture and storage (CCS) has been accepted as a primary option to mitigate anthropogenic CO2 emissions. There are few large-scale CCS facilities in operation at present: (i) Petra Nova Carbon Capture, Texas, USA; (ii) SaskPower Boundary Dam- CCS; (iii) Kemper County Energy Facility (IGCC + CCS); and (iv) Callide – Oxy-fuel combustion and carbon storage demonstration plant. Furthermore, there have been some emerging small-scale PCC projects, most of which use ammonia or proprietary amines as a solvent.

Carbon dioxide (CO2) is one of the most important greenhouse gases (GHG). The most dominant source of anthropogenic CO2 contributing to the rise in atmospheric concentration since the industrial revolution is the combustion of fossil fuels. These emissions are expected to result in global climate change with potentially severe consequences for ecosystems and mankind. In this context, these emissions should be restrained in order to mitigate climate change. Carbon Capture and Storage (CCS) is a technological concept to reduce the atmospheric emissions of CO2 that result from various industrial processes, in particular from the use of fossil fuels (mainly coal and natural gas) in power generation and from combustion and process related emissions in industrial sectors. The Intergovernmental Panel on Climate Change (IPCC) regards CCS as “an option in the portfolio of mitigation actions” to combat climate change (IPCC 2005). However, the deployment of CO2 capture at power plants and large industrial sources may influence local and transboundary air pollution, i.e. the emission of key atmospheric emissions such as SO2, NOX, NH3, Volatile Organic Compounds (VOC), and Particulate Matter (PM2.5 and PM10). Both positive as negative impacts on overall air quality when applying CCS are being suggested in the literature. The scientific base supporting both viewpoints is rapidly advancing. The potential interaction between CO2 capture and air quality targets is crucial as countries are currently developing GHG mitigation action plans. External and unwanted trade-offs regarding air quality as well as co-benefits when implementing CCS should be known before rolling out this technology on a large scale. The goal of this chapter is to provide an overview of the existing scientific base and provide insights into ongoing and needed scientific endeavours aimed at expanding the science base. The chapter outline is as follows. We first discuss the basics of CO2 capture, transport and storage in section 2. In section 3, we discuss the change in the direct emission profile of key atmospheric pollutants when equipping power plants with CO2 capture. Section 4 expands on atmospheric emissions in the life cycle of CCS concepts. We provide insights in section 5 into how air quality policy and GHG reduction policy may interact in the Netherlands and the European Union. Section 6 focuses on atmospheric emissions from post-combustion CO2

Qatar is the biggest exporter of liquefied natural gas, LNG, in the world and is a main oil-producing member of The Organization of Petroleum Exporting Countries, OPEC. A fossil fuel-based industry emerged around the ports of Ras Laffan and Mesaieed, Qatar's industrial cities, perusing industrial diversity and maximising the huge fossil fuel reserves that serve as the primary feedstock for the industrial sector. LNG, crude oil, and petroleum products has given Qatar a per capita GDP that ranks among the highest in the world with the lowest unemployment. This also has given Qatar a per capita CO2 emissions among the highest in the world. A recent report from The World Health Organisation, stated that the capital of Qatar, Doha, is one of the world's most polluted cities and its air ranked the 12th highest average levels of small and fine particles which are particularly dangerous to health [1]. The people and wise leadership of Qatar recognizes the significance of the problem and made environmental develop...

Carbon dioxide (CO2) emitted into the atmosphere by fossil fuel combustion is the most significant greenhouse gas contributing to climate change. Use of coal alone accounts for 43% of global CO2 emission in 2010. As the most abundant, the most reliable and cheap energy source, coal will continue to play a significant role in the world’s economy and improving people’s standard of living in particular in the developing countries. With the strong demand for coal, there is no doubt that the CO2 emissions will continue to rise. On May 9, 2013, the daily mean concentration of carbon dioxide in the atmosphere of Mauna Loa, Hawaii, surpassed 400 ppm for the first time since measurements began in 1958. The rate of increase is ca 2.1 ppm per year during the last 10 years. Without significant reduction of CO2 emissions, it is unlikely to limit the long-term concentration of greenhouse gasses to 450 ppm CO2 by 2050. Carbon capture and storage (CCS) is a process CO2 is separated from large point sources, including fossil fuel power plants, and transported to a disposal site, normally an underground geological formation, for permanent storage. It is generally agreed that CCS is the only technology available to make deep cuts in greenhouse gas emissions while still using fossil fuels and much of today’s energy infrastructure. According to the International Energy Agency (IEA), CCS will account for 19% of total emissions reduction if the global CO2 emissions are halved by 2050. However, looking back, there has been great uncertainty surrounding the commercial implementation of CCS technologies. Despite the fact that all the necessary components of CCS process are commercially available, the question about the large scale CO2 storage remains. The progress towards the commercial deployment of CCS technologies is slow. A number of factors contribute to a slow progress of CCS development. Firstly, the CCS projects are very costly. Most studies estimate that CCS will add more than 50% to the cost of electricity from coal. The costs for the first commercial CCS plants will be much higher than the following projects. No one wants to take the risk to be the first one. Secondly, CCS depends on the political polices to drive it. There is no a legally binding agreement on the emissions reduction applied to all countries and there is no market for CCS. Last but not the least, CCS depends on the government support. In an unfavourably financial environment, the R & D spending is expected to decline. Recently Australian government has announced a budget cut of $500 million over three years to its national CCS flagship program, almost one third of the total funding from the federal government. The Australia’s opposition party has even pledged to abolish the carbon tax if elected in September 2013. So, what is the future for CCS? It is a difficult question to answer. A critical issue is who is going to pay for the development of CCS. It should be pointed out that the majority of the upcoming projects use captured CO2 for enhanced oil recovery. The reason for that is EOR can facilitate the development of CCS by improving the financial viability of the CCS, building the infrastructure required for CCS, and developing capability along the supply chain. An increase in EOR projects reflexes the importance of CO2 utilisation. Carbon Capture, Utilisation and Storage (CCUS) is gaining increased attention in particular in USA and China. It is unlikely for the developing counties to deploy the CCS technologies with financial support from the government alone. In these countries the priorities are to sustain the economic growth and improve people’s living standard. To move CCS forward, it is important to realise the challenges facing the CCS development and make appropriate adjustment based on the political and economic realities. Considering that the funding on the development of CCS is limited, the international R & D program needs to be well coordinated and have the right focus and the right scale to avoid unproductive overlap between demonstration projects and ensure that limited resources are spent wisely to achieve the highest benefits. As a researcher working on CO2 capture, I am glad to

The highly urbanized area around Los Angeles is dotted with oil fields and refineries. Oil wells perch in yards, parking lots, even schools. The Wilmington oil field, which stretches beneath much of the land between Los Angeles and its port, as well as for miles off the coast, supplies numerous local refineries that in recent years have shut down repeatedly during power outages. Restarting the facilities often causes clouds of odorous and potentially hazardous gas to be released. After a 3 October 2007 shutdown, for example, a ConocoPhillips refinery released a cloud of “yellow, metallic dust” containing what company representatives called “a mixture of iron, copper, nickel, aluminum, carbon, and other elements,” according to the local DailyBreeze.com news service.

Carbon dioxide (CO2) is an important material in many industries but is also representing more than 80% of greenhouse gases (GHGs). Anthropogenic carbon dioxide accumulates in the atmosphere through burning fossil fuels (coal, oil, and natural gas) in power plants and energy production facilities, and solid waste, trees, and other biological materials. It is also the result of certain chemical reactions in different industry (e.g., cement and steel industries). Carbon capture and storage (CCS), among other options, is an essential technology for the cost-effective mitigation of anthropogenic CO2 emissions and could contribute approximately 20% to CO2 emission reductions by 2050, as recommended by International Energy Agency (IEA). Although CCS has enormous potential in numerous industries and petroleum refineries due their large CO2 emissions, a significant impediment to its utilization on a large scale remains both operating and capital costs. It is possible to reduce the costs of CCS for the cases where industrial processes generate pure or rich CO2 gas streams, but they are still an obstacle to its implementation. Therefore, significant interest was dedicated to the development of improved sorbents with increased CO2 capacity and/or reduced heat of regeneration. However, recent results show that phase equilibria, transport properties (e.g., viscosity, diffusion coefficients, etc.) and other thermophysical properties (e.g., heat capacity, density, etc.) could have a significant effect on the price of the carbon. In this context, we focused our research on the phase behavior of physical solvents for carbon dioxide capture. We studied the phase behavior of carbon dioxide and different classes of organic substances, to illustrate the functional group effect on the solvent ability to dissolve CO2. In this chapter, we explain the role of phase equilibria in carbon capture and storage. We describe an experimental setup to measure phase equilibria at high-pressures and working procedures for both phase equilibria and critical points. As experiments are usually expensive and very time consuming, we present briefly basic modeling of phase behavior using cubic equations of state. Phase diagrams for binary systems at high-pressures and their construction are explained. Several examples of phase behavior of carbon dioxide + different classes of organic substances binary systems at high-pressures with potential role in CCS are shown. Predictions of the global phase diagrams with different models are compared with experimental literature data.
