Carbon capturing
This document provides an overview of carbon capture and storage (CCS) systems. It discusses the need to reduce CO2 emissions to mitigate climate change. CCS systems aim to capture over 80% of CO2 emissions from power plants and industrial facilities, transport it via pipelines or ships, and store it underground in geological formations or in the deep ocean. The document describes different capture methods including pre-combustion, post-combustion, and oxyfuel combustion. It also discusses transportation and storage options as well as some real-world CCS project sites. While CCS could significantly reduce emissions, the technology is currently very expensive and poses risks if CO2 leaks from storage locations. More research is still needed to improve C
CARBON CAPTURE AND STORAGE
Carbon capture and storage (CCS) is a technology that captures up to 90% of carbon dioxide emissions from fossil fuel power plants and industrial facilities before they enter the atmosphere. It consists of three parts: capturing CO2 through pre-combustion, post-combustion, or oxy-fuel combustion; transporting the captured CO2 via pipelines or ships; and storing the CO2 deep underground in porous rock formations. There are currently four commercial-scale CCS plants operating globally. While CCS could reduce CO2 emissions by 80-90% compared to plants without it, it also increases energy costs and requires significant energy to capture and compress the CO2.

Carbon Capture and Storage
January 2024. Carbon Capture is the process of capturing Carbon Dioxide gas (CO2) produced by industrial processes, preventing its release into the atmosphere.
The primary goal of carbon capture is to reduce carbon emissions, because carbon dioxide is the primary Greenhouse Gas (GHG) contributing to climate change.
Carbon Capture, Utilization, and Storage (CCUS), also known as (CCS), refers to a suite of technologies that perform carbon capture.
CCUS involves four stages: capture, transport, storage, and use.
CCUS technologies include Enhanced Oil Recovery (EOR), carbon sequestration, Direct Air Capture (DAC), and carbon absorption by Ammonia.
Policy wise, growing recognition of CCUS role in meeting net zero goals is translating into increased policy support for CCUS deployment. The Intergovernmental Panel on Climate Change (IPCC) have outlined an important role for CCUS to reach net zero emissions by 2050, directly supporting Sustainable Development Goal SDG13: Take urgent action to combat climate change and its impacts.
In this slideshow, you will learn about the definition, technologies, benefits, challenges, UN policy, and global statistics of carbon capture. Discover how CCUS technologies can reduce global carbon emissions by up to 90% to accelerate the clean energy transition and meet net zero emission goals by 2050.

Achieving the target set during COP21 will require the deployment of a diverse portfolio of solutions, including fuel switching, improvements in energy efficiency, increasing use of nuclear and renewable power, as well as carbon capture and storage (CCS).
It is in the context of CCS that carbon capture and utilisation (CCU), or conversion (CCC), is often mentioned. Once we have captured and purified the CO2, it is sometimes argued that we should aim to convert the CO2 to useful products such as fuels or plastics, or otherwise use the CO2 in processes such as enhanced oil recovery (CO2-EOR). This is broadly referred to as CCU.
In this webinar, Niall Mac Dowell, Senior Lecturer (Associate Professor) in the Centre for Process Systems Engineering and the Centre for Environmental Policy at Imperial College London, presented about the scale of the challenge associated with climate change mitigation and contextualise the value which CO2 conversion and utilisation options can provide.ย
Carbon Capture And Storage
Carbon capture and storage aims to prevent CO2 emissions from large stationary sources like power plants from entering the atmosphere. It involves capturing about 90% of CO2 emissions, compressing and transporting it, then permanently storing it underground. CO2 can be stored in deep saline formations or depleted oil and gas fields, where it becomes trapped between rock grains and in the pores of reservoir rocks. Several CCS projects have already stored millions of tons of CO2 underground for decades. While CCS could help slow the rise of atmospheric CO2, it is still a relatively new technology that requires further development and legal/regulatory frameworks to become widely implemented.
Carbon capture and storage
This document discusses carbon capture and storage (CCS) technologies. It describes different carbon capture methods such as pre-combustion, post-combustion, and cryogenic capture. Post-combustion requires large volumes of solvent and can produce toxic byproducts. Pre-combustion has high construction costs and decreased flexibility. The captured carbon is then transported via pipelines and stored geologically. However, CCS projects face economic challenges like a lack of market incentives and need for large storage volumes. While CCS could enable a transition away from fossil fuels, the technology has yet to be widely implemented due to these technical and economic difficulties.
CCUS-2021 FactBook.pdf
The document provides an overview of carbon capture, utilization and storage (CCUS) technologies and development. It summarizes that CCUS involves capturing carbon dioxide emissions from large industrial sources, transporting it, and storing it underground or utilizing it. The document notes that while CCUS development is important for achieving climate goals, current progress is not on track to meet targets. It also summarizes that CCUS could help decarbonize hard-to-abate sectors and that fuel transformation and cement production are projected to be the fastest growing adopters of CCUS. However, the document states that CCUS development faces challenges from unfavorable economics, challenges in scaling up, regulatory gaps, and lack of public support.

CO2 Separation - A Proposal
This document discusses various methods for capturing carbon dioxide (CO2) from industrial processes and power plant flue gases. It describes both established and developing absorption-based techniques using liquid solvents such as amines, ionic liquids, and hyperbranched polymers. While amine scrubbing is a mature process, opportunities exist to improve solvent capacity and reduce regeneration energy needs through new solvent formulations and process designs. Developing technologies like facilitated transport membranes and task-specific ionic liquids also aim to enhance CO2 capture efficiency. Fundamental research on reaction mechanisms and new candidate materials continues to inform the design of more effective and economical CO2 capture systems.
Methanol synthesis from industrial CO2 sources
Kishan Kasundra presented on methanol synthesis from industrial CO2 sources. Two case studies were analyzed: direct CO2 to methanol (d-CTM) and synthesis gas to methanol (sg-CTM). The d-CTM process consumed more utilities and CO2 per ton of methanol but emitted slightly more CO2. The sg-CTM process optimized methanol production at high hydrogen-carbon ratios and was less resource intensive. Both achieved high methanol yields but differed in raw material use and carbon emissions. The presentation concluded the sg-CTM route may be preferable due to lower resource use and carbon emissions per ton of methanol produced.

Biomass can be converted into energy through direct combustion, gasification, or biochemical processes. Direct combustion involves burning biomass to produce heat, while gasification converts it into a combustible gas mixture through incomplete combustion. Biochemical processes use bacteria and microorganisms to produce fuels like methane from raw biomass through fermentation or anaerobic digestion. Anaerobic digestion of wet biomass produces biogas, which is around 55-65% methane, through decomposition by anaerobic bacteria.

Carbon-di-oxide into fuel
Nanotechnology allows for the conversion of carbon dioxide into usable fuel. Carbon dioxide levels in the atmosphere are rising at 2.2 parts per million per year and are projected to exceed 400 parts per million in 2016. Nanoporous membranes and metal organic frameworks can be used to capture carbon dioxide through thermodynamic potentials and porous crystalline structures, respectively. The captured carbon dioxide can then be converted into methane fuel using nanosized catalysts at low temperatures and pressures or through titania nanotubes and a co-catalyst using sunlight.

Advanced Biofuels Feedstocks Conference
Carbon dioxide (CO2) is both a friend and foe as the greatest greenhouse gas by volume. However, downstream products that utilize CO2 as a feedstock can make it less of a foe by converting it into useful materials like plastics, fuels, chemicals and building materials. Applying and converting CO2 into products like plastics is of great interest as it can replace 50% of the petroleum-based content in some plastics and represents an important carbon reduction scheme. Beyond direct utilization, CO2 applications in enhanced oil recovery, concrete curing, algae cultivation and other industrial processes also provide environmentally friendly uses and net greenhouse gas reductions.
Hydrogen Economy -H2 production.pdf
Hydrogen can be produced through various methods such as steam reforming of natural gas, gasification of biomass/coal, and electrolysis of water. Steam reforming involves a reaction of methane and steam over a nickel catalyst to produce hydrogen and carbon monoxide. Gasification converts carbon sources through partial oxidation to produce syngas. Electrolysis uses electricity to split water into hydrogen and oxygen through redox reactions. Hydrogen has the highest energy density by mass of common fuels and can help enable a green energy economy when produced from renewable resources.
Reverse combustion (1)
Reverse combustion is a proposed process that could help reduce increasing CO2 levels in the atmosphere by reversing the combustion reaction. It involves collecting CO2 from power plant flue gases, combining it with water and a catalyst like bicarbonate solution using renewable energy as heat. This would cause the CO2 and water to undergo a reaction producing hydrocarbons like fuels. While challenging due to the high energy needs, reverse combustion could help address global warming by reusing CO2 emissions rather than adding more to the atmosphere.
Hydrogen fuel & its sustainable development
1. Hydrogen is a colorless, odorless gas that is highly flammable and can be produced through various methods such as electrolysis of water, thermochemical processes using heat, and from fossil fuels.
2. Hydrogen has advantages over fossil fuels as a fuel as it produces no carbon dioxide emissions and has additional potential uses, but current production methods from natural gas produce emissions. Sustainable production could come from renewable resources and water.
3. Key challenges to developing a hydrogen economy include reducing the costs of production, storage, fuel cells, and building out hydrogen infrastructure for delivery and distribution. Countries are working to address these challenges through research and development.
Hydrogen
Hydrogen has many potential industrial applications but faces challenges in production, storage, and safety. It is primarily produced through steam methane reforming, which accounts for 48% of global hydrogen. Other methods include electrolysis and gasification of fossil fuels or biomass. Hydrogen is used in various industrial processes but storage remains an issue due to its low density. Further development is needed to establish hydrogen as a sustainable energy carrier.

Alternative Fuel:CO2
as we all know the bad effect of co2 on our environment,we created a negative image of CO2 but researchers are view CO2 as the source of fuel.
Using Carbondi-oxide as Fuel
This document discusses several methods for utilizing carbon dioxide as a fuel source. It describes processes for capturing carbon dioxide from the atmosphere or industrial sources and storing it underground or in oceans. It also discusses using extremophile bacteria that can convert carbon dioxide into organic compounds at high temperatures, as well as converting carbon dioxide into methanol or other hydrocarbon fuels through photocatalysis using sunlight. The goal is to reduce carbon dioxide levels in the atmosphere by converting it into usable fuels that only release the amount of carbon dioxide used to produce them.
What is 1 tonne Carbon Dioxide? (CO2e) carbon footprint and embodied carbon
This document discusses perspectives on a single tonne of carbon dioxide equivalent (CO2e) emissions. It provides context on CO2e and sustainable development. It then examines what can be produced with 1 tonne of CO2e emissions from different perspectives: transport (distances traveled by various modes), food (amounts of various foods, drinks), and materials (amounts of various materials). The document emphasizes that reducing embodied carbon through design and material choices does not necessarily increase costs. It promotes using influence in design, specification, purchasing, and disposal to reduce CO2e emissions.
Co2 removal through solvent and membrane
1) Carbon dioxide separation from fossil fuel combustion gases is important for reducing greenhouse gas emissions. Amine-based chemical absorption is the most common existing method, using solvents like monoethanolamine (MEA) to capture CO2.
2) However, MEA absorption requires high energy costs for solvent regeneration. New solvents are being developed to improve the efficiency and reduce costs of CO2 capture from power plant flue gases.
3) Key challenges include the low pressure of flue gases, oxygen and sulfur oxide content, and solvent degradation. Integrating capture with power plants could utilize low-grade waste heat to reduce energy costs.

Chemical Looping Combustion
Chemical Looping Combustion (CLC) is a combustion technology that inherently captures carbon dioxide. It involves circulating an oxygen carrier between two reactors, oxidizing the carrier in one reactor using air and then combusting the fuel with the reduced carrier in the other reactor. This produces a flue gas stream with only CO2 and H2O, avoiding the need for costly separation of CO2. CLC has advantages over other CO2 capture methods like post-combustion capture in that it has no efficiency penalty and near-zero emissions. Research is ongoing to improve oxygen carriers and reactor designs to optimize the efficiency and stability of CLC systems.
Need of co2 capture new
This document summarizes a technical seminar presentation on oxygen carriers used in chemical looping combustion. Chemical looping combustion is a process for carbon dioxide capture that uses metal oxides as oxygen carriers in two interconnected fluidized bed reactors - an air reactor and a fuel reactor. In the fuel reactor, gaseous fuel reacts with the metal oxide to produce carbon dioxide, water and heat. The reduced metal oxide is then reoxidized in the air reactor. Nickel, copper, iron and manganese are common oxygen carriers that must be stable, fluidizable, resistant to agglomeration and mechanically durable. The selection of oxygen carrier is a key aspect, with nickel oxide and iron oxide being favorable but having different properties and reactivities

- 3. Fire Suppression What is CO2 โข CO2 is naturally Occuring Gas โข Ozone depletion potential โข Global warming potential โข CO2 is colourless and odourless โข CO2 is stored as a liquid in a cylinder
- 4. How does CO2 work โข CO2 is discharged directly on to the surface and displaces the oxygen. โข CO2 reduces the oxygen level to below that which can support combustion โข CO2 creates a cooling effect on the fire and surrounding areas โข The minimum CO2 fire extinguishing concentration of 34%
- 5. Fire Extinguisher โข CO2 is suitable for surface & deep seated class โAโ fires โข CO2 is suitable for flammable liquids & gas applications โข CO2 is suitable for live electrical equipment applications
- 6. Conversion to Plastics โข It's clear that there's too much carbon dioxide in Earth's atmosphere, heavily contributing to a warming planet โข Plastic itself isn't the most environmentally friendly of materials, but not only would it mean that CO2 gets converted into something useful, it could also reduce the need to produce plastics out of fossil fuels, giving us a better chance of hitting targets for limiting climate change. โข The new approach is to convert carbon dioxide into ethylene the raw material used to make the most commonly used plastic, polyethylene.
- 7. Plastics โข The researchers used a technique involving X- ray spectroscopy and computer modelling techniques analyzing matter with electromagnetic radiation to identify their key catalyst. โข The catalyst is necessary to power a carbon dioxide reduction reaction, While many metals can act as catalysts, we already know that copper is the only one that can produce ethylene. โข Now the research work is going out that how to control the reaction so that ethylene production was maximized, while waste products such as methane were kept to a minimum.
- 8. Fuel Recovery HYDROCARBON FUEL FROM CO2 THROUGH PHOTOCATALYSIS โข Direct conversion of CO2 and water into hydrocarbon fuels using sunlight โข The CO2 is collected and passed through a photo catalytic sieve; in the sieve the CO2 is exposed to sunlight and with the addition of water it is converted back into a hydrocarbon fuel. โข the photo catalytic reduction of CO2 with H2 and or H2O is done with nitrogen doped titania as catalyst
- 9. Photo reduction of CO2
- 10. CONVERSION OF CO2 INTO METHANOL โข methanol (CH30H) can be turned into a form of bio-diesel fuel and burned in engines. โข This technique uses a thermal process to coat copper oxide (CuO) nanowires with another form of copper oxide (Cu2O) and submerging them in a solution rich in carbon dioxide
- 11. โข The CuO-Cu2O hybrid nano rod arrays are then subjected to sunlight to make a chemical reaction and produce liquid methanol. โข The experiments generate methanol with 95percent efficiency
- 12. Food / Products โข Carbon dioxide is a food additive used as a acidity regulator in the food industry โข Carbon dioxide is used to produce carbonated soft drinks and soda water โข The carbonation in beer and sparkling wine came about through natural fermentation, but many manufacturers carbonate these drinks with carbon dioxide recovered from the fermentation process โข Carbon dioxide in the form of dry ice is often used in the wine making process to cool down bunches of grapes quickly
- 13. โข Co2 is widely used in food processing industries. โข In food packaging industries it is used to extend the shelf life of salads,fresh meat and poultry โข Carbon dioxide also inhibits bacteria growth and lowers the pH of preserved food.
