This document discusses how to reduce carbon dioxide (CO2) emissions and help the environment by capturing and storing CO2 from flue gas emissions. Additionally, the researchers suggest converting CO2 into methane, a useful gas that can reduce pollution and promote sustainability. The main goal is to combine carbon capture and storage (CCS) with methane production to make the technology more practical and sustainable. This approach provides benefits like reducing CO2 emissions, increasing energy security, and creating renewable energy—all aimed at combating climate change and ensuring a better future for generations to come.
