Carbon emissions from power plants constitute one of the largest environmental crises facing the modern world due to their slow dispersion and direct impact on climate change and natural ecosystems. Conversely, global demand for electrical energy is rising at an unprecedented rate, placing immense pressure on conventional fossil fuel resources. This scientific article aims to highlight the development of advanced chemical catalysts as an innovative engineering solution that combines effective gaseous emission treatment with high-efficiency carbon capture, directly contributing to supporting the sustainability of modern power plants. Since the beginning of industrial expansion, power generation facilities have become a primary source of chemical emissions across all sectors; however, the continuation of these emissions has turned into an environmental burden because carbon gases persist for long decades before dispersing naturally and biologically. With the growing global shift toward circular economies, the need arose to transform these emissions from a mere environmental burden into capturable and usable feedstocks, where the catalyzed chemical reaction linking combustion byproducts to capture media forms the bridge connecting emission management with clean electrical power generation. The process of carbon capture relies on developing catalysts and chemical materials with high porosity, involving a process of chemical separation and stabilization of carbon molecules in flue gases before their release into the atmosphere. The process begins by routing power plant emissions, cleaning them of solid impurities, and cooling them, after which these gases enter chemical absorption reactors containing precise catalysts at specified temperatures and pressures. Driven by the catalytic reaction, carbon molecules convert into bound compounds that are released at high concentration during catalyst regeneration to produce pure, capture-ready carbon gas for storage or conversion, alongside clean exhaust emissions. Not all chemical materials are equal in terms of capture efficiency and energy savings, as catalysts containing high proportions of metal-organic frameworks and nanostructured surfaces serve as the most effective options. Amine-based catalysts, porous nanomaterials, and active metal oxides stand out as top-performing media delivering high carbon capture and fixation yields reaching over eighty percent of input emission mass. Conversely, un-optimized conventional catalysts are typically excluded from this process, as they require excessively high thermal energy during regeneration, cause reactor corrosion, and yield harmful emissions. The captured and extracted carbon exhibits high physicochemical purity comparable to standard industrial gases, making it suitable for direct utilization across various chemical and industrial applications. This captured gas can be reacted in varying proportions with hydrogen or utilized directly after purification to produce liquid fuels and hydrocarbon materials to power generators. Furthermore, excess thermal energy generated during the chemical reaction process is harnessed directly for steam generation to drive turbines within the facility, achieving energy self-sufficiency for operational units. This strategy delivers integrated environmental and economic benefits; it reduces gaseous discharge volumes and lowers the carbon footprint associated with fossil fuel combustion and refining. It also provides a localized, cost-effective energy framework for industrial regions, thereby supporting the circular economy and creating new job opportunities in carbon capture and alternative energy plant management. Despite promising opportunities, several challenges hinder the commercial scaling of this technology, such as the high manufacturing cost of nanocatalysts and the requirement for emission purification from acidic impurities prior to entering sensitive reactors. Developing more efficient and low-cost chemical catalysts remains the decisive factor in making power plant carbon capture a commercially competitive option compared to traditional energy solutions in the coming decades.
