The construction industry is a major contributor of CO 2 emissions. Carbonation, involving the reaction with alkaline reactants, immobilizes into thermodynamically stable carbonates used in materials such as concrete and aggregates. utilization considered one most promising routes for carbon sequestration, $400 billion market opportunity potential to reduce annual emissions by up 3 Gt 2030. Thi...

CO2 geological utilization and storage is considered as an effective approach to deeply cut anthropogenic emissions. It vital enhance the amount of stored in subsurface, at same time ensure safe long-term subsurface without any leakage. Science engineering research modeling concepts, experimental approaches, safety assurance emerging technologies have driven advancement recent years. In order e...

Growing evidence indicates that the CO2 emissions from the combustion of fossil fuels are contributing to global climate change. One indispensable approach to controlling CO2 emissions to the atmosphere is carbon capture, utilization and sequestration (CCUS) from large point sources, such as coal power plants. Membrane technology has emerged as an important separation technology for CO2 capture...

Economical and efficient carbon capture, utilization, and sequestration technologies are a requirement for successful implementation of global action plans to reduce carbon emissions and to mitigate climate change. These technologies are also essential for longer-term use of fossil fuels while reducing the associated carbon footprint. We demonstrate an O2-assisted Al/CO2 electrochemical cell as...

Rising atmospheric CO2 and deliberate CO2 sequestration in the ocean change seawater carbonate chemistry in a similar way, lowering seawater pH, carbonate ion concentration and carbonate saturation state and increasing dissolved CO2 concentration. These changes affect marine plankton in various ways. On the organismal level, a moderate increase in CO2 facilitates photosynthetic carbon fixation ...
