Abstract
Abstract The Earth’s average surface temperature has risen by roughly 1.55°C since the pre-industrial era of 1850–1900, according to the World Meteorological Organization (WMO, 2024). Presently, the planet is facing a rapid phase of global warming primarily driven by human-induced carbon dioxide (CO₂) emissions, a major contributor to climate change and extreme weather phenomena. This research focuses on creating a cost-effective, small-scale prototype to capture CO₂ from stationary sources such as coal-fired power plants, cement manufacturing plants, and steel industries. The captured carbon is then converted into calcium carbonate (CaCO₃), a versatile compound with practical applications in construction, cement production, and as a filler in paper and plastic industries. The method relies on solvent-based absorption—an established post-combustion carbon capture method within the broader Carbon Capture, Utilization, and Storage (CCUS) paradigm. In addition to capture, the study explores long-term underground geological storage options such as saline aquifers and depleted gas fields, as well as utilization pathways that transform CO₂ into valuable industrial products. This integrated approach not only prevents CO₂ emissions from reaching the atmosphere but also promotes sustainable reuse and permanent containment. The proposed strategy has the potential to contribute significantly to climate mitigation efforts and help India advance toward its Net Zero Greenhouse Gas (GHG) emissions target by 2050.
