不可再生的一次能源的消耗导致其枯竭，这对人类的可持续发展正变得绝对至关重要。基于燃烧化石燃料的电力生产涉及有害排放。因此，需要额外消耗一次能源，以弥补对环境的影响。单位有用产品初级火用消耗量称为TEC（热生态成本）指数。本文提出了基于热生态成本的全生命周期评价的概念，并对一个集CO2捕集、输送和封存于一体的OFC（富氧燃烧）电厂进行了评价。的LC TEC的数学模型进行了评估，并利用波兰的条件下的例子。所获得的值的LC TEC的分析CCS（碳捕获和存储）系统（与90%的CO2减排）是约22%，高于波兰燃煤电厂（没有CCS）的平均值。关于LC TEC的敏感性分析的结果可以得出这样的结论，运行阶段占主导地位（超过99.5%），因此CCS系统的建设，维修和退役阶段可以忽略在进一步的研究有关的不可再生自然资源的枯竭。
The consumption of non-renewable primary energy resources results in their depletion, which is becoming absolutely crucial for the sustainable development of humankind. The production of electricity based on burning fossil fuels involves harmful emissions. Thus, the additional consumption of primary energy is required in order to make up for the environmental impact. The of that consumption of primary exergy per unit of useful products is called the index of TEC (thermoecological cost). When the whole life cycle is considered, we have to do with the LC TEC (life-cycle thermoecological cost).The paper presents the concept of a life cycle assessment based on the thermoecological cost implemented in an integrated OFC (oxy-fuel combustion) power plant with CO2capture, transport and storage. A mathematical model evaluating the LC TEC was applied and the example utilised Polish conditions.The obtained value of the LC TEC of the analyzed CCS (Carbon capture and storage) system (with 90% CO2emission reduction) is about 22% higher than the average value for polish coal-fired power plants (without CCS). The results of sensitivity analysis concerning LC TEC allow to conclude that the operation phase dominates (over 99.5%), thus the construction, repairs and decommissioning phases for CCS systems could be neglected in further studies concerning the depletion of non-renewable natural resources.
