The use of heat from the CO2 compression system for production of system heat

The study presents the concept and computations of the CO2 compression for the purposes of transport and underground storage of the gas. Cooling between individual stages is needed to reduce the power needed for CO2 compression. Heat obtained from the cooling process can be used to provide heat to the municipal heat power systems. A design of a heat accumulator for storage of excess heat was proposed in order to improve heat supply safety. The solution proposed in the study allows for heating condensing power units using waste heat from the CO2 cooling process.
