    The paper describes a combined cycle power plant with carbon capture installation in a post-combustion technology. Carbon dioxide is separated from flue gas by using a chemical absorption method with monoethanolamine (MEA) as a sorbent. Separated carbon dioxide is compressed in order to prepare for transportation to the storage place. This paper identifies the electric efficiencies and other characteristic parameters of power plants before and after implementation of CO2 capture installation, as well as the power plant efficiency drop, and the improvement of ecological characteristics related to the implementation of this installation. The implementation of the installation described herein is associated with the efficiency loss caused by the auxiliary power for additional installations. The CO2 separation installation is powered by heat energy required for reclaiming the sorbent. This energy is taken in the form of steam extracted from the steam cycle, thus reducing the steam turbine power output, while the CO2 compression installation is powered by electric energy.

    The paper presents technologies currently being developed for methanol production and its applications. Particular attention was paid to energy storage technology in the form of “renewable” methanol, which is produced from hydrogen generated from surplus energy from renewable energy sources and from captured CO2. The global methanol market was characterized, i.e. global demand, major producers and global demand for products made from methanol. The installation of methanol production and purification with stoichiometry as well as the methodology for assessing the efficiency of such an installation are also presented. The results of the analysis of such an installation were discussed in accordance with the methodology given.
