Supercritical carbon dioxide cycle is expected to be applied as a novel power cycle in fields of fossil-fired power, concentrated solar power, and nuclear power due to its potential advantage of high efficiency. Material property is a key factor for cycle efficiency. Two proposals for fossil-fired power and concentrated solar power were designed based on the highest property of current ultra-supercritical power plant materials, and double-reheat operation conditions were set for recompression mode. The extreme efficiency of supercritical carbon dioxide cycle was analyzed. The results showed that the two sets of parameters both exhibited high efficiency characteristics and exceeded the efficiency level of the steam cycle power system. Based on the current available materials, supercritical carbon dioxide cycle may have satisfying application value.
