“…Oxy-fuel combustion technology involves the use of pure oxygen combined with recovered fuel gas to burn low-nitrogen fuel. Oxy-fuel combustion technique produces ultra-clean fuel, but it is more expensive to process because it requires fuel compression and dehydration equipment [36]. Consequently, due to high operational costs, large-scale initiatives can fail quickly, which is detrimental to climate change mitigation efforts.…”

Future carbon dioxide capture and storage (CCS) will be impacted by the new scenario in which the energy supply rapidly shifts from oil-based to natural gas-based means, but this shift also presents an opportunity to utilize natural gas hydrates (NGHs). This review discusses the present state of CCS research and development, the advantages of the various approaches, and the barriers to commercialization that exist today. It also provides an evaluation of certain practical small- and large-scale CCS applications. The high initial investment, as well as ongoing maintenance costs, plague today’s commercially accessible CO2 capture technologies, including absorption, adsorption, membranes, and cryogenic separation. Gas hydrate-based capture has the potential to become the dominant method for CO2 separation because of the high recovery rates and purity it provides. Hydrate-based technologies, including CO2 capture, CO2 separation, and transportation, can also be used to reduce greenhouse gas emissions and have excellent application potential. Despite this, the potential of technology based on gas hydrates to help reduce the effects of climate change in the future has received little attention. This study discusses cosmopolitan energy provision and environmental challenges and conversions, and the role of gas hydrates in the carbon cycle. This paper summarizes the state-of-the-art developments in hydrate-based reactors, thereby providing a perspective on the roles of NGHs in the future energy supply and climate change mitigation. In all these areas, we focus on identifying future CCS challenges and the technological development risk in gas hydrate-based systems, which should be highlighted in the next several decades.

“…Due to the high concentration of CO 2 in vented gas (up to 85%), there may be new opportunities for carbon dioxide capture and storage (CCS) in gas processing [72]. An analysis of industrial CO 2 stated that potential industrial CO 2 use was restricted, and CO 2 storage duration in industrial items was often quite short [73]. As a result, industrial CO 2 usage is unlikely to significantly reduce climate change.…”

The Kingdom of Saudi Arabia has been experiencing consistent growth in industrial processes and product use (IPPU). The IPPU’s emission has been following an increasing trend. This study investigated time-series and cross-sectional analyses of the IPPU sector. Petrochemical, iron and steel, and cement production are the leading source categories in the Kingdom. In recent years, aluminum, zinc, and titanium dioxide production industries were established. During the last ten years, a significant growth was observed in steel, ethylene, direct reduce iron (DRI), and cement production. The growth of this sector depends on many factors, including domestic and international demand, socioeconomic conditions, and the availability of feedstock. The emissions from IPPU without considering energy use was 78 million tons of CO2 equivalent (CO2eq) in 2020, and the cement industry was the highest emitter (35.5%), followed by petrochemical (32.3%) and iron and steel industries (16.8%). A scenario-based projection analysis was performed to estimate the range of emissions for the years up to 2050. The results show that the total emissions could reach between 199 and 426 million tons of CO2eq in 2050. The Kingdom has started initiatives that mainly focus on climate change adaptation and economic divergence with mitigation co-benefits. In general, the focus of such initiatives is the energy sector. However, the timely accomplishment of the Saudi Vision 2030 and Saudi Green Initiative will affect mitigation scenarios significantly, including in the IPPU sector. The mitigation opportunities for this sector include (i) energy efficiency, (ii) emissions efficiency, (iii) material efficiency, (iv) the re-use of materials and recycling of products, (v) intensive and longer use of products, and (vi) demand management. The results of this study will support the Kingdom in developing an appropriate climate change mitigation roadmap.

“…There have been many small-scale field experiments and over 25 years of studies of CO 2 ocean storage, but it has not yet been implemented or completely evaluated [93]. However, for this technology to be deployed widely, it should be costeffective, the environmental impacts must be considered, the techniques must be politically and legally feasible, and scientific certainty must be increased as to the effectiveness of the oceans to sequester CO 2 safely [94]. Figure 11 shows an illustration of some ocean storage strategies [93].…”

Circular Carbon Economy (CCE): A Way to Invest CO2 and Protect the Environment, a Review

et al. 2021

Increased levels of carbon dioxide have revolutionised the Earth; higher temperatures, melting icecaps, and flooding are now more prevalent. Fortunately, renewable energy mitigates this problem by making up 20% of human energy needs. However, from a “green environment” perspective, can carbon dioxide emissions in the atmosphere be reduced and eliminated? The carbon economic circle is an ideal solution to this problem, as it enables us to store, use, and remove carbon dioxide. This research introduces the circular carbon economy (CCE) and addresses its economic importance. Additionally, the paper discusses carbon capture and storage (CCS), and the utilisation of CO2. Furthermore, it explains current technologies and their future applications on environmental impact, CO2 capture, utilisation, and storage (CCUS). Various opinions on the best way to achieve zero carbon emissions and on CO2 applications and their economic impact are also discussed. The circular carbon economy can be achieved through a highly transparent global administration that is supportive of advanced technologies that contribute to the efficient utilisation of energy sources. This global administration must also provide facilities to modernise and develop factories and power stations, based on emission-reducing technologies. Monitoring emissions in countries through a global monitoring network system, based on actual field measurements, linked to a worldwide database allows all stakeholders to track the change in greenhouse gas emissions. The process of sequestering carbon dioxide in the ocean is affected by the support for technologies and industries that adopt the principle of carbon recycling in order to maintain the balance. This includes supporting initiatives that contribute to increasing vegetation cover and preserving oceans from pollutants, especially chemicals and radioactive pollutants, which will undoubtedly affect the process of sequestering carbon dioxide in the oceans, and this will contribute significantly to maintaining carbon dioxide at acceptable levels.
