Dans cet article, l’association Équilibre des énergies invite les pouvoirs publics à mettre en place une stratégie de développement à la hauteur des bénéfices que peuvent apporter les technologies de captage, stockage et valorisation du CO 2 — CCS / CCU en anglais (Carbon Capture and Storage / and Utilisation) — pour répondre aux enjeux climatiques. En effet, la sidérurgie, la chimie, la production de ciment, de produits pétroliers, de chaleur industrielle ou encore l’agroalimentaire sont autant de filières émettrices de CO 2 susceptible d’être capté pour être ensuite transporté, stocké et / ou valorisé, notamment dans des carburants de synthèse bas-carbone à destination des secteurs aérien et maritime.

L’article revient sur les oppositions publiques qui accompagnent la démonstration des techniques de captage, transport et stockage du CO2 (CTSC) en Europe. Le CTSC regroupe plusieurs techniques visant à séparer et capter le dioxyde de carbone de ses sources industrielles, à le transporter vers un lieu de stockage et à l’isoler de l’atmosphère sur le long terme. Dans un contexte où le changement climatique devient un enjeu reconnu, la stratégie d’un stockage visant à gérer les rejets de CO2 d’origine industrielle gagne en puissance. Durant la dernière décennie, la Commission européenne s’est engagée en partenariat avec des acteurs industriels dans une démarche de « démonstration » du CTSC articulée autour du développement de démonstrateurs sur site afin d’amener ces techniques à un stade commercial. L’article revient sur deux projets industriels abandonnés en 2010. L’analyse permet de saisir les relations entre politique transnationale et échelle locale. Elle révèle les limites d’un modèle de développement technologique qui reporte l’épreuve de la démonstration du CTSC au niveau européen sur les sites, tout en ignorant le potentiel de politisation de cette démonstration au niveau local.

Cet article examine le rôle essentiel de la Norvège dans le façonnement du paysage énergétique européen, dans le nouveau contexte des bouleversements géopolitiques provoqués par l’invasion de l’Ukraine par la Russie. Il présente une analyse approfondie des interconnexions énergétiques de la Norvège avec le nord de l’Europe, en mettant l’accent sur le contexte historique qui sous-tend leur importance. Alors que l’Europe cherche à réduire sa dépendance aux importations russes, les interconnexions de la Norvège et ses solides capacités d’approvisionnement sont devenues cruciales. L’essai explore le débat international et les controverses entourant les bénéfices énergétiques de la Norvège, en particulier dans le sillage de la guerre en Ukraine, tout en soulignant l’engagement du pays en faveur de la stabilité mondiale par le biais d’initiatives significatives d’aide étrangère, telles que le programme de soutien Nansen pour l’Ukraine. Enfin, l’essai se penche sur les défis énergétiques nationaux de la Norvège, en particulier la hausse des prix de l’électricité et les plans à long terme du pays en faveur des alternatives énergétiques soutenables, telles que le captage du carbone et les technologies de l’hydrogène. Tout au long de l’article, l’accent est mis sur la complexité de la position de la Norvège, qui navigue entre priorités nationales et responsabilités internationales, et illustre l’interaction complexe de la politique, de l’économie et de l’énergie dans le contexte unique de la Norvège, ainsi que son impact sur le paysage énergétique européen.

The rapid and steady increase in the concentration of CO2, the most abundant greenhouse gas in the atmosphere, leads to extreme weather and climate events. Due to the burning of fossil fuels (oil, coal and natural gas), the concentration of CO2 in the air has been increasing in recent decades by more than 2 ppm per year, and in the last year alone - by 3.29 ppm. To prevent the "worst" scenarios of climate change, immediate and significant reductions in CO2 emissions through carbon management are needed. Aim. Analysis of the current state of research and prospects for the use of carbonic anhydrase in environmental decarbonization programs. Results. Carbonic anhydrase (CA) is an enzyme that accelerates the exchange of CO2 and HCO3 in solution by a factor of 104 to 106. To date, 7 types of CAs have been identified in different organisms. CA is required to provide a rapid supply of CO2 and HCO3 for various metabolic pathways in the body, explaining its multiple independent origins during evolution. Enzymes isolated from bacteria and mammalian tissues have been tested in CO2 sequestration projects using carbonic anhydrase (CA). The most studied is one of the isoforms of human KAz - hCAII - the most active natural enzyme. Its drawbacks have been instability over time, high sensitivity to temperature, low tolerance to contaminants such as sulphur compounds and the impossibility of reuse. Molecular modelling and enzyme immobilisation methods were used to overcome these limitations. Immobilisation was shown to provide greater thermal and storage stability and increased reusability. Conclusions. Capturing carbon dioxide using carbonic anhydrase (CA) is one of the most cost-effective methods to mitigate global warming, the development of which requires significant efforts to improve the stability and thermal stability of CAs.

Porous carbon materials derived from sugars have been prepared by a new method using silica aerogel as a template. The silica aerogels were prepared by the reaction of tetramethyl orthosilicate (TMOS) and formic acid in the presence of sugar (d‐fructose, d‐glucose, or sucrose). Prepared silica aerogels containing sugar were carbonized under inert atmosphere followed by the removal of silicate with KOH solution to obtain the porous carbon materials. Prepared porous carbons with smaller amount of TMOS show higher surface areas (up to 312.2 m2/g) than the carbons prepared sugars themselves without using TMOS (108.7–277.3 m2/g). However, the surface areas of porous carbons decreased dramatically at the weight ratios of TMOS/sugar over 0.25. By increasing the surface areas of porous carbons, CO2 adsorption capacities of porous carbon materials increased up to 3.73 mmol/g.

Porous carbon materials with tunable porosities and functionalities represent an important class of CO2 sorbents. The development of porous carbons from various types of biomass is a sustainable, economic and environmentally friendly strategy. Wood is a biodegradable, renewable, sustainable, naturally abundant and carbon-rich raw material. Given these advantages, the use of wood-based resources for the synthesis of functional porous carbons has attracted great interests. In this mini-review, we present the recent developments regarding sustainable porous carbons derived from wood-based biopolymers (cellulose, hemicelluloses and lignin) and their application in CO2 capture.

Carbon dioxide CO2 is a component of air that is responsible for the growing global warning and greenhouse gases emissions. The energy sector is one of the main sources of CO2 emissions in the world and especially in Ukraine. Carbon capture, utilization and storage (CCUS) is a group of technologies that play a significant role along with renewable energy sources, bioenergy and hydrogen to reduce CO2 emissions and to achieve international climate goals. Nowadays there are thirty-five commercial CCUS facilities under operation around the world with a CO2 capture capacity up to 45 million tons annually. Tougher climate targets and increased investment provide new incentives for CCUS technologies to be applied more widely. CCUS are applications in which CO2 is captured from anthropogenic sources (power generation and industrial processes) and stored in deep geological formations without entering atmosphere or used in various products using technologies without chemical modification or with conversion. The article discusses the use of various technologies of CO2 capture (post-combustion capture, pre-combustion capture and oxy-combustion capture), CO2 separation methods and their application in the global energy transition to reduce the carbon capacity of energy systems. Technical and economic indicators of CO2 capture at different efficiencies for coal and gas power plants are given. Technologies of transportation and storage of captured carbon dioxide and their economic indicators are considered. The directions for the alternative uses of captured CO2, among which the main ones are the production of synthetic fuels, various chemicals and building materials, are also presented and described in the paper. The possibility of utilization captured СО2 in the production of synthetic fuel in combination with Power-to-Gas technologies was studied. Keywords: greenhouse gases emissions, fossil fuels, СО2 capture technologies, capture efficiency, synthetic fuel

Carbon dioxide (CO2), a major greenhouse gas, capture has recently become a crucial technological solution to reduce atmospheric emissions from fossil fuel burning. Thereafter, many efforts have been put forwarded to reduce the burden on climate change by capturing and separating CO2, especially from larger power plants and from the air through the utilization of different technologies (e.g., membrane, absorption, microbial, cryogenic, chemical looping, and so on). Those technologies have often suffered from high operating costs and huge energy consumption. On the right side, physical process, such as adsorption, is a cost-effective process, which has been widely used to adsorb different contaminants, including CO2. Henceforth, this review covered the overall efficacies of CO2 adsorption from air at 196 K to 343 K and different pressures by the carbon-based materials (CBMs). Subsequently, we also addressed the associated challenges and future opportunities for CBMs. According to this review, the efficacies of various CBMs for CO2 adsorption have followed the order of carbon nanomaterials (i.e., graphene, graphene oxides, carbon nanotubes, and their composites) < mesoporous -microporous or hierarchical porous carbons < biochar and activated biochar < activated carbons.

Anthropogenic CO2 emissions rapidly increased during the post-industrial revolution causing global warming issues. In order to reduce the CO2 concentration in the atmosphere Carbon Capture and Sequestration will play a key transition role to transform into clean energy by utilizing the existing oil and gas infrastructure and subsurface data. The technology comes with certain challenges, amongst them, one of the real threats is the stored CO2 leakage back into the atmosphere and at shallower surfaces. This work talks about the understanding of geomechanical risks involved in the CCS process and probable ideas to mitigate the risks. CO2 injection leads to an increase in the pressure within the pores which eventually results in a change of stress and strain conditions within the reservoir. With a proper understanding of the reservoir and with a realistic field dataset a controlled injection can avoid a formation leading to geomechanical failures. Often field data are insufficient, in such a scenario this works talks about the preventive measures that can be adopted to avoid early mentioned calamity

Abstract Activated carbons (ACs) prepared from common nettle (Urtica Dioica L.) were studied in terms of carbon dioxide adsorption. ACs were prepared by KOH chemical activation in a nitrogen atmosphere at temperatures (ranging from 500 to 850°C). The pore structure and the surface characterization of the ACs were specified based on adsorption-desorption isotherms of nitrogen measured at –196°C and carbon dioxide at 0°C. The specific surface area was calculated according to the BET equation. The pore volume was estimated using the DFT method. The highest values of the specific surface area (SSA) showed activated carbons produced at higher carbonization temperatures. All samples revealed presence of micropores and mesopores with a diameter range of 0.3–10 nm. The highest value of the CO2 adsorption, 4.22 mmol/g, was found for the material activated at 700°C.

Nowadays one of the biggest challenges for carbon materials is their use in CO2 capture and their use as electrocatalysts in the oxygen reduction reaction (ORR). In both cases, it is necessary to dope the carbon with nitrogen species. Conventional methods to prepare nitrogen doped carbons such as melamine carbonization or NH3 treatment generate nitrogen doped carbons with insufficient nitrogen content. In the present research, a series of activated carbons derived from MOFs (ZIF-8, ZIF-67) are presented. Activated carbons have been prepared in a single step, by pyrolysis of the MOF in an inert atmosphere, between 600 and 1000 °C. The carbons have a nitrogen content up to 20 at.% and a surface area up to 1000 m2/g. The presence of this nitrogen as pyridine or pyrrolic groups, and as quaternary nitrogen are responsible for the great adsorption capacity of CO2, especially the first two. The presence of Zn and Co generates very different carbonaceous structures. Zn generates a greater porosity development, which makes the doped carbons ideal for CO2 capture. Co generates more graphitized doped carbons, which make them suitable for their use in electrochemistry.

Major fossil fuel consumption associated with CO2 emission and socioeconomic instability has received much concern within the global community regarding the long-term sustainability and security of these commodities. The capture, sequestration, and conversion of CO2 emissions from flue gas are now becoming familiar worldwide. Nanostructured carbonaceous materials with designed functionality have been extensively used in some key CO2 exploitation processes and techniques, because of their excellent electrical conductivity, chemical/mechanical stability, adjustable chemical compositions, and abundant active sites. This review focuses on a variety of carbonaceous materials, like graphene, carbon nanotubes, amorphous porous carbons and carbon hybrid composites, which have been demonstrated promising in CO2 capture/separation and conversion (electrocatalysis and photocatalysis) to produce value-added chemicals and fuels. Along with the discussion and concerning synthesis strategies, characterization and conversion and capture/separation techniques employed, we further elaborate the structure-performance relationships in terms of elucidating active sites, reaction mechanisms and kinetics improvement. Finally, challenges and future perspectives of these carbon-based materials for CO2 applications using well-structured carbons are remarked in detail.

Low-cost activated carbons were prepared from waste polyurethane foam by physical activation with CO2 for the first time and chemical activation with Ca(OH)2, NaOH, or KOH. The activation conditions were optimized to produce microporous carbons with high CO2 adsorption capacity and CO2/N2 selectivity. The sample prepared by physical activation showed CO2/N2 selectivity of up to 24, much higher than that of chemical activation. This is mainly due to the narrower microporosity and the rich N content produced during the physical activation process. However, physical activation samples showed inferior textural properties compared to chemical activation samples and led to a lower CO2 uptake of 3.37 mmol·g−1 at 273 K. Porous carbons obtained by chemical activation showed a high CO2 uptake of 5.85 mmol·g−1 at 273 K, comparable to the optimum activated carbon materials prepared from other wastes. This is mainly attributed to large volumes of ultra-micropores (<1 nm) up to 0.212 cm3·g−1 and a high surface area of 1360 m2·g−1. Furthermore, in consideration of the presence of fewer contaminants, lower weight losses of physical activation samples, and the excellent recyclability of both physical- and chemical-activated samples, the waste polyurethane foam-based carbon materials exhibited potential application prospects in CO2 capture.

The demand for energy has increased tremendously around the whole world due to rapid urbanization and booming industrialization. Energy is the major key to achieving an improved social life, but energy production and utilization processes are the main contributors to environmental pollution and greenhouse gas emissions. Mitigation of the energy crisis and reduction in pollution (water and air) difficulties are the leading research topics nowadays. Carbonaceous materials offer some of the best solutions to minimize these problems in an easy and effective way. It is also advantageous that the sources of carbon-based materials are economical, the synthesis processes are comfortable, and the applications are environmentally friendly. Among carbonaceous materials, activated carbons, graphene, and carbon nanotubes have shown outstanding performance in mitigating the energy crisis and environmental pollution. These three carbonaceous materials exhibit unique adsorption properties for energy storage, water purification, and gas cleansing due to their outstanding electrical conductivity, large specific surface areas, and strong mechanical strength. This paper reviews the synthesis methods for activated carbons, carbon nanotubes, and graphene and their significant applications in energy storage, water treatment, and carbon dioxide gas capture to improve environmental sustainability.

The design and synthesis of porous carbons for CO2 adsorption have attracted tremendous interest owing to the ever-soaring concerns regarding climate change and global warming. Herein, for the first time, nitrogen-rich porous carbon was prepared with chemical activation (KOH) of commercial melamine formaldehyde resin (MF) in a single step. It has been shown that the porosity parameters of the as-prepared carbons were successfully tuned by controlling the activating temperature and adjusting the amount of KOH. Thus, as-prepared N-rich porous carbon shows a large surface area of 1658 m2/g and a high N content of 16.07 wt%. Benefiting from the unique physical and textural features, the optimal sample depicted a CO2 uptake of up to 4.95 and 3.30 mmol/g at 0 and 25 °C under 1 bar of pressure. More importantly, as-prepared adsorbents show great CO2 selectivity over N2 and outstanding recyclability, which was prominently important for CO2 capture from the flue gases in practical application. An in-depth analysis illustrated that the synergetic effect of textural properties and surface nitrogen decoration mainly determined the CO2 capture performance. However, the textural properties of carbons play a more important role than surface functionalities in deciding CO2 uptake. In view of cost-effective synthesis, outstanding textural activity, and the high adsorption capacity together with good selectivity, this advanced approach becomes valid and convenient in fabricating a unique highly efficient N-rich carbon adsorbent for CO2 uptake and separation from flue gases.

Its relatively low cost and high surface area makes activated carbon an ideal adsorbent candidate for H2S removal. However, physical adsorption of H2S is not very effective; therefore, methods to facilitate reactive H2S oxidation on carbons are of interest. The performance of H2S removal of non-impregnated, impregnated, and doped activated carbon in low-temperature syngas was evaluated in fixed-bed breakthrough tests. The importance of oxygen content and relative humidity was established for reactive H2S removal. Impregnates especially improved the adsorption rate compared to non-impregnated carbons. Non-impregnated carbons could however retain a high capture capacity with sufficient contact time. In a relative performance test, the best performance was achieved by doped activated carbon, 320 mg g−1. Ammonia in syngas was found to significantly improve the adsorption rate of non-impregnated activated carbon. A small quantity of ammonia was consumed by the carbon bed, suggesting that ammonia is a reactant. Finally, to validate ammonia-enhanced desulfurization, bench-scale experiments were performed in biomass-based gasification syngas. The results show that when the ammonia concentration in syngas was in the tens of ppm range, 40–160 ppm H2S oxidation proceeded rapidly. Ammonia-enhanced oxidation allows utilization of cheaper non-impregnated activated carbons by in situ improvement of the adsorption kinetics. Ammonia enhancement is therefore established as a viable method for achieving high-capacity H2S removal with unmodified activated carbons.

The design of novel porous solid sorbents for carbon dioxide capture is critical in developing carbon capture and storage technology (CCS). We have synthesized a series of nitrogen-rich porous organic polymers (POPs) from crosslinking melamine and pyrrole monomers. The final polymer’s nitrogen content was tuned by varying the melamine ratio compared to pyrrole. The resulting polymers were then pyrolyzed at 700 °C and 900 °C to produce high surface area nitrogen-doped porous carbons (NPCs) with different N/C ratios. The resulting NPCs showed good BET surface areas reaching 900 m2 g−1. Owing to the nitrogen-enriched skeleton and the micropore nature of the prepared NPCs, they exhibited CO2 uptake capacities as high as 60 cm3 g−1 at 273 K and 1 bar with significant CO2/N2 selectivity. The materials showed excellent and stable performance over five adsorption/desorption cycles in the dynamic separation of the ternary mixture of N2/CO2/H2O. The method developed in this work and the synthesized NPCs’ performance towards CO2 capture highlight the unique properties of POPs as precursors for synthesizing nitrogen-doped porous carbons with a high nitrogen content and high yield.

Human-generated carbon emissions are the leading cause of climate change. There is a global commitment to reduce carbon emissions, in an effort to limit climate change effects. Many climate change solutions involve the mitigation of carbon emissions, mitigation alone is not enough. Carbon Dioxide (CO2) can live in the atmosphere for over 100 years. If we were to switch to 100% renewable energies, we would still damage the planet with the stagnant CO2 from the 1920’s. To combat climate change, we need a solution that can remove this carbon. One such solution is carbon capture, one of our best weapons in tackling climate change. The replacement of fossil fuel energy will not happen in the next few years, maybe not even for decades. Therefore, carbon capture is a promising ‘bridge’ technology, while we reach a sustainable level of green energy production. Carbon capture technology development has largely focused on singular processes (typically absorption, adsorption and membranes) capturing carbon from industrial exhaust systems. Recently, studies have delved into the idea of combining two or more of these technologies into one more efficient system and employing them in the industrial exhaust systems but also capturing carbon from the atmosphere. This project aims to develop a hybrid membrane and adsorption unit to capture carbon directly from the atmosphere. The aim is to provide the technology necessary to remove carbon from the atmosphere more effectively and cheaper than earlier technologies.

Net zero is an endeavour that will impact every corner of the world. We need global communication and collaboration. To move fast, the transition must become more efficient and spread the best solutions far and wide. For difficult to decarbonise industries, collaboration is essential. The other essential ingredient is policy. The UK banned diesel and petrol car sales from 2030. This is driving electric vehicle manufacturing and supply chains. The EU banned single-use plastics from 2021. Consequently, Coca Cola Europe announced 100% of their bottles would be based on recycled plastic. Norway introduced a carbon tax in 1991 to encourage research into low-carbon solutions. It became the first country to geologically sequester CO2 and the first to do it from an LNG facility. Ten years after the tax was introduced, Norway’s carbon emissions had dropped by 14%. Policies influence emissions. They drive not only environmental outcomes but also sustainable growth and the ability to future-proof their economies. In 2007 and 2012, the UK announced funding for a commercial-scale carbon capture and storage project, both times the programs were aborted. A third attempt, this time focussing on decarbonising four industrial clusters by 2030, was announced in 2018 along with the first ‘net-zero’ carbon cluster by 2040, with the support of a number of UK policies it is expected to progress to construction. This paper discusses the journey from policy through partnerships to the development of Carbon Capture and Hydrogen Clusters in the UK and looks at lessons learnt for Australia.
