The CO2 capturing technologies as applied to FCC flue gas in order to reduce GHG (green house gases) were evaluated and compared in this review. Although the CCS (carbon capture and storage) idea has been proposed for more than 30 years, there has been little commercial success of CCS projects. The largest issue is where to store the massive amount of captured pure CO2 every year. Therefore, the review will focus on the efficient use of power or heat to reduce CO2 emission and how to recycle the use of produced CO2 before it is emitted to the atmosphere rather than being captured and stored. The scenarios with oxyfiring, microalgae-cofiring or biogas burning to treat FCC flue gas are introduced and discussed.

Carbon capture and storage (CCS) constitutes an extremely important technology that is constantly being improved to minimize the amounts of carbon dioxide (CO2) entering the atmosphere. According to the Global CCS Institute, there are more than 320 worldwide CCS projects at different phases of progress. However, current CCS processes are accompanied with a large energy and efficiency penalty. This paper models and simulates a post-combustion carbon capture system, that uses absorption as a method of separation, in Aspen Plus V7.2. Moreover, the CAPE-OPEN Simulated Annealing (SA) Capability is implemented to minimize the energy consumed by this system, and allow coal-fired power plants to use similar carbon capture systems without losing 20 to 40 % of the plant's output.

Transport Phase

Carbon (dioxide) capture and storage (ccs) is one of the solutions for decarbonising society whereby CO2 is captured, transported, and injected into geological formations. It can be transported to offshore locations through pipelines or ships. Which method provides for a better deal for investors depends to an extent on the financial risk associated with these two methods, which in turn is linked with exposure to liability. This paper compares the potential liability arising from the carriage of CO2 by ships and by pipelines in the uk offshore context. The two modes of transport are governed by significantly different regimes, even though they concern the same material. It is argued that the transport of CO2 by ships and by pipelines poses similar risks and therefore they should have a similar liability regime. This would afford pipeline operators the economic advantages available to shipowners and incentivise investment in the transport phase of ccs.

Change Mitigation

The latest technologies for climate change mitigation are carbon capture and storage (CCS). Some countries are developing CCS projects, and they are currently at different stages of deployment. Despite the signing of international agreements on climate change mitigation, Russia’s efforts to develop and implement CCS technologies are quite limited. Therefore, it is vital that people are aware of the importance of carbon dioxide capture, utilization, and storage. The purpose of this article is to produce guidelines and toolkits to form a system of measures aimed at raising awareness of the Russian society on carbon dioxide capture and storage technologies. The paper discusses the key findings of several recent studies on the topic, e.g., a study focusing on the level of environmental consciousness among St. Petersburg students; a content analysis of the Russian school textbooks; a study of environmental groups in Russian social media; and an experimental study on creating eco-comics and posters as educational tools for promoting environmental awareness. A multi-level system of educational activities is proposed, including events for preschoolers, schoolchildren, students, and adults.

Considering the interaction between climate and energy policies, this paper analyzes the activities of Carbon Capture and Storage in the Brazilian context of public choices. The methodology of the work consists of normative and bibliographical revision, using the qualitative and deductive methods. The hypothesis of this research corroborates the thesis that the governance of Carbon Dioxide Capture and Storage activities in Brazil is found in the already existing configuration proposed for public policies directed to climate and energy changes in the country.

Climate change poses a serious threat to the development of the current and future generations. Therefore, Carbon Dioxide Capture, Transportation, Utilization and Storage (CCUS) has emerged as an essential tool to mitigate such impacts of global warming along with other  initiatives and strategic decisions such as energy transition and conservation, sustainable practices amongst others. This article is focused on the  CCUS practices and more specifically the peculiarities of CCUS vis-à-vis the standardization rules at the International Organization for  Standardization (ISO). The main question this article aims to address is to determine if CCUS should have its own standing technical committee (TC)  or if it should be somehow related to the existing Carbon Capture and Storage (CCS) technical committee.

Terrain Features

In the carbon capture and storage (CCS) infrastructure, the risk of a high-pressure buried pipeline rupture possibly leads to catastrophic accidents due to the release of tremendous amounts of carbon dioxide (CO2). Therefore, a comprehensive understanding of the effects of CO2 dispersion pattern after release from CCS facilities is essential to allow the appropriate safety precautions to be taken. Due to variations in topography above the pipeline, the pattern of CO2 dispersion tends to be affected by the real terrain features, such as trees and hills. However, in most previous studies, the dynamic impact of trees on the wind field was often approximated to linear treatment or even ignored. In this article, a computational fluid dynamics (CFD) model was proposed to predict CO2 dispersion over shrubbery areas. The shrubs were regarded as a kind of porous media, and the model was validated against the results from experiment. It was found that shrubbery affected the flow field near the ground, enhancing the lateral dispersion of CO2. Compared with that of the shrub-free terrain, the coverage area of the three shrub terrains at 60 s increased by 8.1 times, 6.7 times, and 9.1 times, respectively. The influence of shrub height and porosity on CO2 dispersion is nonlinear. This research provides reliable data for the risk assessment of CCS.

Escherichia coli is gram-negative bacterium that is a workhorse for biotechnology. The organism naturally performs a mixed-acid fermentation under anaerobic conditions where it synthesises formate hydrogenlyase (FHL-1). The physiological role of the enzyme is the disproportionation of formate in to H 2 and CO 2 . However, the enzyme has been observed to catalyse hydrogenation of CO 2 given the correct conditions, and so has possibilities in bio-based carbon capture and storage if it can be harnessed as a hydrogen-dependent CO 2 -reductase (HDCR). In this study, an E. coli host strain was engineered for the continuous production of formic acid from H 2 and CO 2 during bacterial growth in a pressurised batch bioreactor. Incorporation of tungsten, in place of molybdenum, in FHL-1 helped to impose a degree of catalytic bias on the enzyme. This work demonstrates that it is possible to couple cell growth to simultaneous, unidirectional formate production from carbon dioxide and develops a process for growth under pressurised gases. IMPORTANCE Greenhouse gas emissions, including waste carbon dioxide, are contributing to global climate change. A basket of solutions is needed to steadily reduce emissions, and one approach is bio-based carbon capture and storage. Here we present out latest work on harnessing a novel biological solution for carbon capture. The Escherichia coli formate hydrogenlyase (FHL-1) was engineered to be constitutively expressed. Anaerobic growth under pressurised H 2 and CO 2 gases was established and aqueous formic acid was produced as a result. Incorporation of tungsten in to the enzyme in place of molybdenum proved useful in poising FHL-1 as a hydrogen-dependent CO 2 reductase (HDCR).
