Abstract
This article presents the concept of renewable methanol production in the gas turbine cycle. As part of the work, an analysis was performed, including the impact of changing the parameters in the methanol reactor on the obtained values of power, yield and efficiency of the reactor, and chemical conversion. The aim of this research was to investigate the possibility of integrating the system for the production of renewable methanol and additional production of electricity in the system. The efficiency of the chemical conversion process and the efficiency of the methanol reactor increases with increasing pressure and decreasing temperature. The highest efficiency values, respectively η = 0.4388 and ηR = 0.3649, are obtained for parameters in the reactor equal to 160 °C and 14 MPa. The amount of heat exchanged in all exchangers reached the highest value for 14 MPa and 160 °C and amounted to Q˙ = 2.28 kW. Additionally, it has been calculated that if an additional exchanger is used before the expander (heating the medium to 560 °C), the expander’s power will cover the compressor’s electricity demand.

Summary
Methanol currently plays a very important role in the chemical industry and is a promising energy fuel, mainly produced from fossil fuels. CRGT power plants can be an interesting low-carbon technology for the use obtained methanol flow rate enables the supply of a small (several kW) gas turbine of renewable methanol, enabling efficient of surplus renewable energy, andofthen equipped with a methanol reforming sectionstorage in order to increase the efficiency the inproducing electricity with low CO2 emissions. If 10% of the energy produced is used by the electrolysis process to produce hydrogen ternally fired gas turbine (EFGT), a fuel cell (MCFC), an Organic Rankine Cycle (ORC), used in the synthesis of methanol, the overall energy efficiency is 41% In this case, the methanesystem and/or methanol production, and a proton exchange membrane electrolyser uses 1012 tonnes/year of CO2 to produce 393 tons of methanol per year. The proposed installation for the methanol production is shown in Figu initial phase,for carbon dioxide is compressed to an appropriate pressure,
