Abstract:

Carbon capture and storage technology(CCS)and its utilization are important for achieving near-zero CO2 emissions and carbon neutrality.However,the boost of cost and energy consumption of carbon capture will lower the energy efficiency of power systems.The innovation of low-energy carbon capture technology and development of carbon capture technology assisted by high-efficiency renewable energy are important ways to reduce the energy consumption in carbon capture and improve the energy efficiency of the system.The technologies of using renewable energy,waste heat and the combination of them to assist carbon capture are summarized.The status quo and problems of carbon capture technologies assisted by solar energy,wind energy,biomass energy,waste heat and multi-energy combination are analyzed and their development trends are foreseen.The review indicates that,with the innovation and development of renewable energy and waste heat utilization,the cost of CCS can be reduced and the energy efficiency of the system can be improved.Coupling the cooling,heating,powering and lighting by solar energy with chemical conversion in assisting CCS technology can explore the potential in solar energy efficient utilization.The key points of the carbon capture technology assisted by renewable energy,waste heat and combination of them focus on the process match,optimized cascade unitization of energy and the refining of comprehensive evaluation and index system.
