尽管大气中的甲烷浓度远低于二氧化碳，但其温室效应更强，约占全球温室效应的30%。目前缺少有关去除大气甲烷来缓解气候变化的有效方法。增强生态系统的氧化能力以去除大气甲烷是一种绿色方案。本文提出了利用太阳能热气流发电站（SCPP）结合太阳能池来去除大气甲烷的创新概念。对于该系统，臭氧在太阳光的作用下，光解产生羟基自由基。另外，Fe(III)转化为Fe(II)过程中会释放的氯原子。二者协同降解大气中的甲烷。研究结果表明，单个200兆瓦的SCPP结合太阳能池的系统，每年可消除0.22万吨大气甲烷。在全球范围内建造5400个该系统，每年可去除11.9亿吨大气甲烷，从而实现本世纪温升不超过2°C的气候目标。该设备所需投资约为327万欧元。该提案似乎是缓解气候变暖影响的可行途径，但仍需开发深度模型评估其可行性。

The methane concentration in the atmosphere is far lower than that of carbon dioxide, but it is more potent, accounting for 30% of the global greenhouse effect. Although removing atmospheric methane would be an effective way to mitigate climate change, no practical methods have been identified. The enhancement of the oxidative capacity of ecosystems to remove atmospheric methane is a green approach. This paper presents the novel concept of utilizing a solar chimney power plant (SCPP) associated with a solar pond to remove atmospheric methane. In the proposed system, the production of both hydroxyl radicals from ozone photolysis and chlorine atoms from converting Fe (III) to Fe (II) under optimized conditions degrades the atmospheric methane. The results reveal that a 200 MW SCPP associated with a solar pond could eliminate 0.22 million tons of atmospheric methane per year. The construction of 5400 systems worldwide could remove 1.19 billion tons of atmospheric methane per year, achieving the climate goal of a temperature rise of less than 2°C this century. The devices require an investment of about 3.5748×10¹² EUR. Although the proposal seems a promising way to mitigate the effects of a warming climate, a comprehensive model must be developed to evaluate its feasibility.
