A recent study published in the journal Carbon Future discusses the potential of utilizing coke oven gas for hydrogen-driven calcium looping as a cost-effective solution for carbon capture. The research, led by Hao Yu from Guangzhou University, explores how this innovative method could help decarbonize hard-to-decarbonize sectors like steel and cement production by capturing CO2 emissions efficiently. By reversing the chemical process in cement production, calcium looping offers a way to reduce CO2 emissions significantly. The research also highlights the energy efficiency and profitability of using coke oven gas-sourced hydrogen over renewably-produced hydrogen for carbon capture. Additionally, the hydrogen-driven calcium looping process can generate synthetic methane for clean energy use, contributing to a potentially carbon-neutral cycle. This study emphasizes the importance of finding economically viable solutions for carbon capture in industrial processes to address climate change challenges effectively.
