Analysis of solar industrial heat supply

Abstract

The future of Ukraine is only impossible without integration into the European community, including in the fight against climate change. It is possible to make the production of thermal energy more environmentally friendly thanks to the introduction of solar technologies. Solar thermal technologies are necessary for the decarbonization of the industrial sector. Information from open sources on the state and prospects for the development of solar industrial heat supply systems in the world has been analyzed. Analysis of the development of solar heat and steam production for industry in the world has shown that the solar thermal energy market is currently in an early stage of development, but it is actively developing and many projects will be commissioned in the near future. Specific investment costs and economy of solar industrial heat supply systems of various capacities are determined. The average weighted cost of thermal energy for the life cycle is used as a criterion of economy in world practice. Specific investment costs for installing solar systems are significantly reduced when their thermal power is increased. Approximate dependences of average specific investment costs on thermal power were obtained. The specific investment costs of installation and the number of hours of operation significant impact on the average cost of solar heat and steam production for industry. Approximate dependences of the average cost of heat on thermal power at different discount rates and at different power on discount rates were obtained. In Ukraine, it is possible to organize the supply of industry with heat and hot water from the use of solar technologies in a short period of time. A promising direction is the use of solar heat supply systems in combination with other thermal energy sources.
