Research on Global Carbon Dioxide Utilization: Current Status and Future Prospects

The utilization of carbon dioxide CO <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</inf> is a significant technology choice for carbon capture and storage (CCS) technology, which aims to reduce carbon emissions while utilizing CO <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</inf> as a resource. In recent years, CO <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</inf> utilization has received widespread attention from academia and industry at home and abroad, but its development is still in its infancy. In this case, we provide an overview of the current state of technological development and challenges in CO <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</inf> utilization. First, the advantages and main technical routes of CO <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</inf> utilization are reviewed. Then, domestic and international advanced cases are analyzed. Finally, challenges in promoting CO <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</inf> utilization are summarized and some suggestions are given accordingly. This review could shed some light on the goal of achieving carbon neutrality.
