Techno‐economic assessment on the fuel flexibility of a commercial scale combined cycle gas turbine integrated with a CO ₂ capture plant

Impact of Natural Gas Price Variations and Consumption Limitation on the Decarbonization of Sector-Coupled Energy Systems

“…2) MODELLING POWER SYSTEM ASSETS NG-fired, combined-cycle gas turbines (CCGTs) is the only conventional generation technology considered, further subdivided into two categories, without or with a co-located CC unit. The latter feature higher investment cost, as well as lower efficiency [43], [44] due to selfconsumption associated with CO2 emissions capture. More specifically, post-combustion CC technology is assumed, that demands auxiliary electricity and heat for its operation [45], covered through supplementary NG consumption, leading to a lower aggregate efficiency than equivalent non-CC units.…”

Estimation of the Amount of CO2 Chemically Absorbed in Real Time by Measuring the Electrical Conductivity Variation of Monoethanol-Amine Aqueous Solutions

“…Currently, the chemical CO 2 absorption process using alkanolamine-based solvents has been partially commercialized among the various CCUS technologies, and monoethanol-amine (MEA) aqueous solutionthe MEA concentration of which is approximately 30%is the most representative and widely used solvent due to its efficiency, economy, and fast reaction with CO 2 . − Nevertheless, a lot of research has still been conducted to address the low economies of the systems and overcome some remaining technological hurdles of the process. Additionally, some studies have also investigated the feasibility of the process via modeling and simulation. − Recently, however, many papers have focused on the performance of the hybrid solutions manufactured by blending MEA with other amines or additives to reduce the energy penalty of the system. − In addition, other works specifically report the reaction rate, physical and chemical properties of MEA solution under the various absorption conditions, as well as its thermodynamic values. , Prior studies have shown that the reaction mechanism of CO 2 absorption using MEA solution as the solvent is known to be based on two models: zwitterion and termolecular.…”

Nanoporous structured Sn‐MWCNT/Cu electrodes fabricated by electrodeposition–chemical dezincification for catalytic CO2 reduction

“…The rapid economic development and population growth are speeding up the consumption of fossil fuels for energy and emitting more CO 2 and other pollutants into atmosphere, which have been causing the fast exhaustion of unsustainable energy sources and environmental pollution at the same time 1,2 . To mitigate these energy and environmental issues, efforts in exploring clean and sustainable energy sources such as solar, wind, waterfall, sea‐wave, geothermal, etc., as well as the corresponding energy storage and conversion technologies, have become extensive in the last several decades 3,4 . Among the different technologies explored, CO 2 conversion to produce low‐carbon fuels and value‐added chemicals has received great attention recently 5,6 .…”
