This article provides the dataset of working fluid parameters and performance characteristics for the oxy-fuel, supercritical CO2 cycle by the thermodynamic optimization procedure employed in the research article “Thermodynamic optimization and equipment development for a high efficient fossil fuel power plant with zero emissions” (Rogalev et al., 2019) [1]. The performance characteristics of the different air separation units, which were used for the investigation of an influence of the produced oxygen purity on power consumption, are presented. Moreover, the methodology for the evaluation of gross and net efficiency is described. The working fluid parameters and performance characteristics are subdivided into several tables differing from each other by the values of initial pressure.

Mixed ionic-electronic conducting (MIEC) membranes have gained growing interest recently for various promising environmental and energy applications, such as H 2 and O 2 production, CO 2 reduction, O 2 and H 2 separation, CO 2 separation, membrane reactors for production of chemicals, cathode development for solid oxide fuel cells, solar-driven evaporation and energy-saving regeneration as well as electrolyzer cells for powerto-X technologies. The purpose of this roadmap, written by international specialists in their fields, is to present a snapshot of the state-of-the-art, and provide opinions on the future challenges and opportunities in this complex multidisciplinary research field. As the fundamentals of using MIEC membranes for various applications become increasingly challenging tasks, particularly in view of the growing interdisciplinary nature of this field, a better understanding of the underlying physical and chemical processes is also crucial to enable the career advancement of the next generation of researchers. As an integrated and combined article, it is hoped that this roadmap, covering all these aspects, will be informative to support further progress in academics as well as in the industry-oriented research toward commercialization of MIEC membranes for different applications.

“…One of the simplest systems for recovery of liquid nitrogen exergy is direct expansion cycle (figure 2). Liquid nitrogen from cryogenic vessel is pumped (1)(2) to high pressure, then it is heated in HX1 (2-3) using ambient as a heat source. Then it is expanded in 2 stage expander (3-4 and 5-6) with reheating in HX2 (4-5).…”

“…In recent years also the use of oxygen in power generation is investigated. Oxy-combustion is one of promising technologies for reduction ofCO 2 emissions, in this technology pure oxygen is provided to boilers instead of air [1]. The most mature technology of oxygen production is cryogenic air separation.…”

Nitrogen is by-product from cryogenic air separation processes used for oxygen production for metallurgy and oxygen-enriched combustion purposes. If the gases are delivered from air separation unit (ASU) in liquid phase, liquid nitrogen (LN2) can be used as energy accumulator for stabilization of electrical grid system with large share of renewable energy sources. When the energy demand is high and not enough electricity is generated in power plants, energy accumulated in LN2 may be recovered in a cryogenic power cycle. In this research complete exergy analysis of liquid nitrogen direct expansion cycle and combined direct expansion/Brayton cycle was performed.
