One of the renewable energy technologies that has been widely explored internationally is that of CSP Plants (Concentrated Solar Power). In these plants the concentration of solar radiation is used to generate heat and, with this thermal energy, to generate electricity and thermal use in cogeneration. However, the lack of continuity of solar radiation and the high cost of electricity produced by CSP plants, are two significant barriers that compromise further commercial deployment. There are many factors that can contribute to achieving the required cost reduction, while the application of the cost-benefit ratio of thermal energy hybridization systems is still the key point to overcome the discontinuity of solar radiation, because these systems will allow the production of electricity when solar radiation is not available. The best dispatch of the plant, that is, the capacity of the CSP plant to meet the profile of electricity demand, would thus be achieved. In CSP technology plants, the block where thermal energy is converted into electrical energy, the so-called Power Block, adds a system that converts thermal energy into mechanical energy for the subsequent generation of electrical energy, with heat cogeneration, and Solinova has developed a Hybrid Power Block for CSP plants. Steam or gas turbines are commonly used as thermal energy conversion equipment, but the project that Solinova has developed is focused on applications for agribusiness and small and medium agribusiness, and we have opted for the use of a steam engine as a converter equipment. thermal energy in mechanics. Steam turbines, or gas turbines, are more expensive to maintain and much more specialized than steam engines, and can be done by less qualified personnel who have experience with explosion engines. Steam turbines require an amount and quality of steam that can only be achieved with appropriate equipment for the production of enormous amounts of steam at high pressure and temperature, once again requiring specialized and expensive labor, with work requirements in boilers and furnaces complying with pressure vessel safety standards and their respective certifications. Designed to receive steam at a pressure of 20 bar, the engine operates more efficiently, the steam generator integrates with variations in solar radiation and the result is an extremely versatile set for applications in agribusinesses that use heat and electricity in production processes such as dairy, slaughterhouses, slaughterhouses, drying of grains and herbs, leaves, and seeds, oil processing, livestock, poultry etc., which can be coupled with water treatment systems, desalination, effluent treatment and a wide range applications.
