Mineral carbonation using seawater for CO2 sequestration and utilization: A review

Mineral carbonation is an important technology for CO2 sequestration and utilization to address environmental issues arising from climate change. In recent years, seawater has been considered a promising candidate that has relatively alkaline properties, higher Ca2+ and Mg2+ content as well as lower cost than distilled water and chemical solvents. This review assesses the concept and mechanism of mineral carbonation using seawater. Several state-of-the-art technologies are pointed out. Natural seawater, desalination brine, and seawater-based wastewater are all assessed. Herein, the emerging research is highlighted, possible research trends are sug-gested, and constructive perspectives are discussed to allow the impact and development of mineral carbonation technology using seawater to be appropriately assessed.
