“…The main principle of oxyfuel combustion is the burning of the fuel using pure oxygen instead of air, which allows for improved control over flame temperature and recycling of a portion of the flue gas back to the furnace. The advantage of the oxyfuel method is that it generates a highly concentrated CO 2 flue stream, which eases the post-separation process [50], and it only requires CO 2 in most combustion systems [51]. The optimal oxygen concentration for the oxyfuel process is approximately 97% oxygen purity [52].…”

Greenhouse gas emission into the atmosphere is considered the main reason for the rise in Earth’s mean surface temperature. According to the Paris Agreement, to prevent the rise of the global average surface temperature beyond two degrees Celsius, global CO2 emissions must be cut substantially. While a transition to a net-zero emission scenario is envisioned by mid-century, carbon capture, utilization, and storage (CCUS) will play a crucial role in mitigating ongoing greenhouse gas emissions. Injection of CO2 into geological formations is a major pathway to enable large-scale storage. Despite significant recent technological advancements, mass deployment of these technologies still faces several technical and non-technical difficulties. This paper provides an overview of technical milestones reached thus far in CO2 capture, utilization, geological storage, monitoring technologies, and non-technical aspects such as regulatory frameworks and related policies in the US and the rest of the world. This paper describes different injection methods to store CO2 in various subsurface formations, the use of foams and the resulting potential gains in CO2 storage capacity, the role of nanoparticles for foam stabilization, and ensuring long-term storage safety. This work also addresses several safety-related aspects of geological storage and subsurface monitoring technologies that may mitigate risks associated with long-term storage.

The separation of carbon dioxide (CO 2 ) from the flue gas is a challenging one in terms of the energy penalty. The development of a cryogenic or lowtemperature CO 2 separation method helps to overcome the energy penalty associated with CO 2 separation. In this study, a preliminary investigation is carried out in a theoretically modified Linde process which can be used for CO 2 separation from a gas mixture containing CO 2 and N 2 . A cryogenic cooling process is also studied for CO 2 separation of the same quality of the gas mixture. The compression work and cooling loads in each case are analyzed using Aspen Plus software. The effect of CO 2 volume in the mixture, compressor efficiency, and compressor discharge pressure on the energy consumption is studied for both the theoretically modified Linde and the cryogenic cooling processes, and the results are compared between them. The results indicated in the CO 2 separation by the cooling process are better than the modified Linde process. The energy penalty shows for 20% CO 2 composition of separation by the cooling process with the single-stage compression is lower by around 123.9% and 128.8% in terms of compression work and compressor cooling load, respectively, than those of the modified Linde process working in a single-stage compression. The separation by the cooling process refrigeration effect is 15.9% more than in the modified Linde process.

“…The environmental problems caused by fossil energy combustion have become one of the key factors restricting sustainable development. [1][2][3] Biomass is renewable and can be easily obtained from agricultural and forestry wastes. [4][5][6] Although there are large biomass reserves on the Earth, most of them burn directly to produce heat, wasting the natural gift.…”
