🌍 Review of recent process developments in the field of carbon dioxide (CO2) capture from power plants flue gases and the future perspectives. This comprehensive review presents recent developments in post-combustion carbon dioxide (CO2) capture technologies from power plant flue gases. The study evaluates three primary methods—Absorption, Membrane, and Adsorption (AMA) - based on CO2 recovery, energy efficiency, and cost. Advancements in process configurations, particularly the two-stage-hybrid setups, are highlighted as the optimal route for achieving high CO2 purity (≥95mol%) and recovery (≥97mol%). Although these configurations offer promising energy efficiency and cost savings, further techno-economic analyses are required to determine the best configuration for commercial viability. Researchers emphasizes the need for continued research to fine-tune these processes for large-scale deployment. 🌱 👉 Read more about these findings by Donald Obi, Samuel Onyekuru, & Anslem Orga in the study Review of recent process developments in the field of carbon dioxide (CO2) capture from power plants flue gases and the future perspectives at https://lnkd.in/d9htWdhY #GlobalWarming #GreenhouseGases #CO2 #CarbonCapture #ClimateChange #HybridProcessConfigurations Process diagram for CO2 capture by absorption (below).

The fuel cell system can provide electricity in the megawatt range and is suitable for both direct integration in new builds and as retrofits in existing ships. 𝗕𝘂𝘁 𝗵𝗼𝘄 𝗶𝘀 𝘁𝗵𝗲 𝘀𝘆𝘀𝘁𝗲𝗺 𝗰𝗼𝗻𝗳𝗶𝗴𝘂𝗿𝗮𝘁𝗶𝗼𝗻?  The methanol fuel cell system is based on high-temperature (HT) PEM technology combined with methanol-reforming which ensures a simple system design with high energy conversion, efficiency, and system power density, built upon the principle of: INPUT Methanol, water, and air are added to the system. REFORMER The reformer converts the methanol and water into a hydrogen-rich gas. FUEL CELLS Multiple HT PEM methanol fuel cell stacks are placed in 200 kW cabinets. Combining several cabinets in a modular configuration the system can provide an energy load in the megawatt range. Unique for the HT PEM fuel cells is the potential for waste heat utilisation where part of the waste heat from the fuel cells is used to drive the process of reforming methanol and thereby optimising the total system efficiency. Furthermore, waste heat can also be used for additional energy recovery. OUTPUT The output is: ✔ High-grade waste heat at +150°C ✔ High voltage DC ✔ Exhaust water ... additionally, our patented system allows for up tp 100% carbon capture for recycling or storage. #fuelcells #methanol #efuels #maritimedecarbonisation #greenshipping

Yesterday in class, I discussed the various methods of splitting water molecules to obtain green hydrogen. Water splitting, by the way, is a chemical process that involves breaking water into its components hydrogen and oxygen gases. Since this is a non-spontaneous process(ΔG > 0), it usually requires external energy to proceed. The energy could be electrical, solar, or thermal. This document is only an introduction to the topic. However, it also shows the basic chemistry behind each of them. #HydrogenEnergy #GreenHydrogen #CleanEnergy #SustainableEnergy #HydrogenEconomy

💧 𝗥𝗲𝗹𝗶𝗮𝗯𝗹𝗲 𝘀𝗲𝗻𝘀𝗼𝗿𝘀 𝗳𝗼𝗿 𝘀𝘂𝗰𝗰𝗲𝘀𝘀𝗳𝘂𝗹 𝗲𝗹𝗲𝗰𝘁𝗿𝗼𝗹𝘆𝘀𝗶𝘀 Electrolysers play a crucial role in the production of green #hydrogen. In this process, water is split into its individual components, hydrogen and oxygen, using electricity from renewable sources. ⚡ Reliable level and pressure readings are essential here. VEGA’s sensors provide this data – precise and coherent at all required points in the process.  No matter if the application is in an alkaline #electrolyser or in a PEM electrolyser, with aggressive potassium hydroxide or with simultaneous suitability for oxygen and hydrogen: VEGA’s #level and #pressure #sensors fulfil all the necessary prerequisites and ensure efficient regulation of the output. ✅ 💡 Level and pressure measurement in the alkaline electrolyser?

Institute of Energy Economics at the University of Cologne (#EWI) reveals how electrolyzers can ease grid pressure and support hydrogen ramp-up across Germany. Strategically placing electrolyzers can benefit the entire energy system, especially in regions like #Dithmarschen, northern Germany, and the #Rhineland. By 2040, many more regions will be well-suited for system-supporting electrolyzers due to increased hydrogen demand and expanded networks. This shift will enhance the flexibility and stability of the energy system, making it more sustainable and efficient. 🌍 𝐖𝐡𝐲 𝐈𝐭 𝐌𝐚𝐭𝐭𝐞𝐫𝐬: Electrolyzers using renewable energy can prevent grid bottlenecks, reduce system costs, and support the transition to a sustainable energy future. They play a crucial role in linking sectors and creating a more flexible energy system. Gabriel Clemens of E.ON Hydrogen says: "Electrolyzers at many different locations can make a significant contribution to the success of the energy transition.

Understanding Micro-Cracks in Photovoltaic Modules: The Hidden Threat 🌞 On sunny days, photovoltaic (PV) modules quietly convert sunlight into electricity, providing us with a continuous stream of clean energy. However, these seemingly robust components hide a secret: micro-cracks. Let's delve into this often-overlooked issue. Micro-cracks are tiny fractures within PV modules, much like hidden "internal injuries," that are not visible to the naked eye but can significantly impact performance. These cracks can result from mechanical stress during production, temperature fluctuations, or improper installation. Once micro-cracks form, the electrical performance of the module can drop dramatically, potentially leading to more severe failures. Strategies to Address Micro-Cracks: Purchase from Reliable Suppliers: Choose suppliers who use advanced non-destructive testing methods, such as infrared or ultrasonic testing, to detect and address micro-cracks early. Improve Installation Techniques: Ensure high installation standards to avoid excessive mechanical stress during the process. By being aware of these hidden vulnerabilities and taking proactive measures, we can ensure the longevity and efficiency of our photovoltaic systems.
