摘要

可再生能源在追求低碳经济和气候中和中占有重要地位。此外，预计碳捕集、利用和封存（CCUS）技术将在整体经济脱碳中发挥重要作用。可再生能源和CCUS的整合对于未来能源和成本效益的能源系统具有诱人的潜力。沿着这条路线，钙环（CaL）是一种特别有吸引力的技术，可以提供具有热化学储能潜力的高能效。本研究对一个采用热化学储能的太阳能CaL发电厂进行了深入的技术、经济和环境分析，以产生100兆瓦的净电力。考虑到利用CO2和吸附剂储存能量的能力，在灵活的运行条件下对电厂进行了评估。评估表明，太阳能钙环工艺具有良好的技术经济性能：高净功率效率（约42.5%），较低的经济成本，如特定资本投资（约3400欧元/千瓦净功率），约76欧元/兆瓦时脱碳电力的平准化成本，非常有吸引力的低环境影响（通过详细的生命周期分析- LCA进行评估）。所研究的采用CO2和吸附剂储存能力的CaL电厂的灵活性对于最相关的技术、经济和环境性能指标的整体优化是非常有希望的。

Solar-based calcium looping power plant with thermo-chemical energy storage capability: A techno-economic and environmental (LCA) analysis

Renewable energy holds a significant place in the quest for low carbon economy and climate neutrality. Furthermore, the Carbon Capture, Utilization and Storage (CCUS) technologies are foreseen to have a significant role in overall economy decarbonization. The renewables and CCUS integration has an attractive potential for the future energy- and cost-efficient energy systems. Along this line, the Calcium Looping (CaL) is a particular attractive technology to deliver high energy efficiency with thermochemical energy storage potential. The present study performs an in-depth technical, economic and environmental analysis for a solar-based CaL plant with thermo-chemical energy storage to generate 100 MW net electricity. The power plant is assessed in flexible operational conditions in view of energy storage using CO₂ and sorbent storage capabilities. As evaluation shows, the solar calcium looping process has promising techno-economic performances: high net power efficiency (around 42.5 %), lower economic costs such as the specific capital investments (about 3400 €/kW net power), around 76 €/MWh levelized cost of decarbonized electricity and very attractive low environmental impact (evaluated through a detailed Life Cycle Analysis - LCA). The flexibility of investigated CaL power plant using CO₂ and sorbent storage capability is very promising for overall optimization of the most relevant technical, economic and environmental performance indexes.
