Abstract:Under the current background of carbon neutrality, mankind is moving forward on the road of “less carbon, use carbon and no carbon” to reduce CO₂ emission. As the most effective “carbon neutrality” technology strategy, CO₂ capture, utilization and storage technology (CCUS) has played an important role in promoting the net reduction of atmospheric CO₂. However, low efficiency and high energy consumption are issues preventing current CCUS technology from industrial large-scale application. In recent years, with the continuous development of renewable electricity, battery and energy storage technologies that couple CO₂ emission reduction and energy system have emerged. The CO₂ energy utilization technology offers a solution for efficient CO₂ emission reduction technology which is conductive to the periodic consumption of new energy. However, CO₂ is mainly used as an energy medium in this type of CO₂ energy utilization technology, and the external energy output does not stem from CO₂ itself. It is worth noting that the process of converting CO₂ to carbonate is a reaction with lowering the chemical potential, which means that CO₂ itself is also a potential energy source. The author of this article uses this thermodynamically favorable reaction to successfully develop CO₂ mineralized power generation technology which utilizes the energy contained in CO₂ itself for deep power generation. And in recent studies, the maximum power density of the CO₂ mineralization cell has been increased to 96.75 W/m².
