Hydrogen Production using a Hybrid System Built with Renewable Energy Resources in Yenice
Abstract
Benefits of hybrid renewable energy; has a continuous power supply, has a better return on investment, is independent of the grid, has fewer operating hours of the diesel generator, requires less maintenance than a diesel generator system, and does not need frequent refueling, one-time initial capital required, protects from ever-increasing grid electricity tariffs. On the other hand, the demand for renewable energy sources such as wind, solar, hydrogen, biomass, and geothermal, which are the least harmful to nature and natural life, has increased due to the depletion of fossil fuels used in energy production and the greenhouse gases they have released to the environment. Thus, with the inclusion of renewable energy sources in the system, a rich structure in terms of energy diversity has emerged. An area that simulates a system consisting of renewable energy sources using HOMER Pro software and has an annual average electrical energy need of 3997104 kWh/day was selected. Solar radiation and wind data belonging to the region were taken from NASA Surface and used. The energy system of the area where the feasibility study was conducted consists of a generator, wind turbine, solar panel, hydrogen tank, electrifier inverter, and battery system. The energy produced by the resulting system will be used by 11.26 kg/day hydrogen load and 3997104 kWh/day electrical load. The economic evaluation criteria of the hybrid renewable energy system are the energy unit cost of energy production, the net present value (NPC), and the payback period; The environmental evaluation criteria were determined as the renewable energy rate and emission values evaluation criteria. When the renewable energy rate is at the lowest level, the most economical system is the Gen/PV/WT/Bat/300Htank/ H loaded hybrid system when emissions are not considered, while the Gen/PV/WT/Bat hybrid system has the lowest emissions without considering the cost. When the renewable energy rate is high, the most economical system has been the PV/WT/Bat hybrid system when emissions are not considered.
