Mantel’s Post

🌍 [ENG] The recourse to CO2 capture as a feasible solution must not depend solely on technological development to increase the absorption capacity. Another crucial aspect is the storage of CO2 captured from the air or the sea.  📌 And if there has been growing interest on the front in recent years – with some progress, albeit limited, you can see Climeworks’ latest DAC plants – the second front has a slower rate of innovation.  💡 A group of researchers from the University of Austin, Texas, focused on precisely how to make the processes that allow the storage of captured CO2 more efficient. 👉 They developed a system six times faster than current ones, reliable in terms of durability, and without recourse to chemical solvents.  💧 The most widespread method today is the injection of CO2 in a gas-like state into geological deposits. Typically, the choice falls on deposits exhausted from gas and oil.  🔎 However, it also applies to those in danger of depletion, with the pumping of CO2 that allows the extraction of additional amounts of hydrocarbons.  🔋 This model has many margins of uncertainty, both in terms of the speed at which the CO2 captured can be stored and the actual duration of the storage. ⬇️ Link in the first comment #RinnovabiliNET #environmnent #greeneconomy #solar #eolic #energy #greenenergy #solarenergy #windenergy #sustainable #sustainablity #sustainabledevelopment

Post 2: Challenges in carbon capture through absorption In this blog, I will try to create a background by which you will be able to relate past achievements with present scenario related to carbon capture. I understand that lot of my audience do not come from a background in process plant or hydrocarbons, so, I will try to keep things simple. Over a series of articles, my goal is to help you to understand various developments happening in the #carboncapture arena. Continuing from the previous article, here I will discuss about the advantages, disadvantages and challenges faced by #carbondioxide capture using liquid solutions. Advantages of using liquid solutions for carbon removal: · #Economiesofscale: Large volume treatment · #Reusability: The liquid solution can be regenerated and used again and again in a closed loop. · Maturity: These technologies have been for a while and quite reliable. Disadvantages of using liquid solutions for carbon removal: · #Energy intensive: Major sink of energy is during regeneration of the absorbent solution · #Capital intensive, high OPEX and long payback period · Corrosive and hazardous nature of MDEA, DEA and MEA solutions Challenges of using liquid solutions for carbon removal: · Energy sources: The energy for regeneration has to come from renewable sources, otherwise it will defeat the whole purpose of installing a carbon capture plant. · End use: The captured CO2 has to be utilized in some way. Lot of #research is going on to put this CO2 to some good use. We can not do much about the disadvantages, but we can surely mitigate the challenges. In the next article, I will discuss about what is being done to address those challenges.

#Carboncapture offers imminent decarbonisation to many industries and is also deemed to be a crucial part of our #netzero ambitions according to the International Energy Agency (IEA). However, there are mixed reactions for the use of carbon capture, notably in the #hydrogen industry as carbon capture can be used for:   🏭#Bluehydrogen, which could be considered as a tool used by emission heavy industries to sustain polluting activities ⛽#efuels where #CO2 is used as a feedstock to decarbonise the transport sector     Currently there are three main methods for carbon capture from point sources namely  ⚗Post combustion  🔥Oxy-fuel  🧪Pre combustion    and one to capture CO2 from the atmosphere  💨#DirectAirCapture (DAC)    Even though the industry is not at scale, there are 30 projects in operation, 11 under construction and 153 in development according to the Global CCS Institute with the Northern Lights JV project emerging as a hot prospect providing an open-source infrastructure for CO2 transport and storage with  ⌛COD of 2024  🛢Capacity of 1.5 million tons  ��sourcing from #cement plants and #wastetoenergy plants currently There arises the question of which source qualifies as "#greenCO2" with the #EU categorizing CO2 sources into   🏭Point source from industries such as cement 🏭Point source from combustion of fuels for electricity generation  💨Direct air carbon capture (DAC)  🍃#BiogenicCO2 capture from the combustion, decomposition, or processing of biologically based materials or from a geological resource ⛽ CO2 released during the combustion of #renewablefuel with industrial and electrical point sources (🏭) not allowed for use in e-fuels production beyond 2041.

📖 An Overview of Direct Air Capture Systems and Components📖 📍Direct air capture (DAC) is a technology that uses chemical or physical processes to extract carbon dioxide (CO2) directly from the ambient air. 📍The main components of a DAC system are the air contactor, the CO2 desorber, and the CO2 compressor. 📍The air contactor is the device that exposes the air to a liquid solvent or a solid sorbent that can selectively bind with CO2 molecules. 📍The solvent or sorbent is typically circulated through a network of thin plates, tubes, or fibers that increase the surface area for mass transfer. 📍The solvent or sorbent can be based on various chemicals, such as amines, carbonates, hydroxides, or metal-organic frameworks. 📍The CO2 desorber is the device that releases the CO2 from the solvent or sorbent by applying heat or pressure. 📍The heat or pressure breaks the chemical bonds between the CO2 and the solvent or sorbent, resulting in a concentrated stream of CO2 and a regenerated solvent or sorbent. 📍The heat or pressure can be supplied by various sources, such as electricity, natural gas, and biomass, solar thermal or waste heat. 📍The CO2 compressor is the device that compresses the CO2 stream to a suitable pressure for storage or utilization. 📍The compression process requires energy and may involve multiple stages of cooling and drying. 📍The compressed CO2 can be transported by pipelines, trucks, ships, to a storage site or a utilization facility. 📍The overall performance and cost of a DAC system depend on several factors, such as the capture efficiency, the energy consumption, the material consumption, the capital expenditure, and the operating expenditure. 📍According to the International Energy Agency (IEA), the current levelized cost of DAC ranges from $200 to $600 per tonne of CO2 captured. 📍According to the same source, this cost could be reduced by technological innovation, economies of scale, policy support, and market incentives. #netzero #decarbonisation #carboncapture #energy

Pre-Combustion Carbon Capture Today, we’ll explore pre-combustion carbon capture which separates the CO2 before combustion occurs. Pre-combustion carbon capture has different names depending on the industry, such as Blue Hydrogen and gasification with carbon capture. ⚙ How it works:  Fuel is processed to remove carbon before combustion and recover hydrogen, which does not emit CO2 when combusted. The process is typically carried out at high pressure and has relatively high CO2 concentrations, 10-40% CO2. ♻ Applications: Pre-combustion carbon capture can decarbonize industries that use, or could use, hydrogen as a feedstock or fuel. These include power plants (e.g Integrated Gasification Combined Cycles), steel mills (e.g. Direct Reduction), and other pathway's that involve hydrogen as an energy carrier (e.g. Synthetic Fuels). 💡 Opportunities: Pre-combustion carbon capture offers potential cost and energy efficiency advantages over post-combustion methods because separating CO2 from hydrogen in a pre-combustion environment is inherently easier than separating CO2 from nitrogen post-combustion. Many capture technologies, including Mantel's, can be applied to both pre- and post- combustion. ⚠ Challenges: Pre-combustion systems are not easily retrofitted into existing facilities, and new constructions come with high capital costs. In addition, it is easier to transport and store carbon containing fuels than hydrogen which should be considered when deciding where to separate CO2 in the system. #precombustion #CCUS #carboncapture #industry #energy

Carbon dioxide capture and storage (CCS) involves separating CO2 from emission sources, transporting it, and storing it to prevent its release into the atmosphere. The three main capture technologies are postcombustion capture, integrated gasification combined cycle, and oxyfuel, but they come with higher generation costs and energy penalties. Current research aims to reduce costs across these technologies. Realistically, CCS is most feasible for large point-source emitters like power stations and natural gas plants, coupled with geological storage. Carbonlocked Technologies Incorporated can play a crucial role in this technology by offering innovative solutions to store captured CO2 safely and cost-effectively for centuries. By employing advanced geological storage techniques and ensuring long-term isolation from the atmosphere, Carbonlocked can provide a reliable and environmentally sound solution for CCS projects. Additionally, Carbonlocked's expertise in minimizing energy penalties and optimizing capture processes can further enhance the efficiency and affordability of CCS implementations, making them more attractive for widespread adoption. #carbon #capture #CO2 #Environmental
