Potential measurement of electricity supply

Abstract Hydrogen has a therapeutic effect in a wide range of diseases and its presence in medical centers is essential. Hydrogen can increase efficiency along with renewable energy systems (green hydrogen). Due to the importance of the above, in the present work for the first time, the feasibility of hydrogen production on a hospital scale using water electrolysis by wind, solar and biomass energies has been investigated. The aim of the present work is to supply renewable electricity to four hospital hydrogen generators of MD-H2 400 model. Technical-economic-environmental-energy analyses were performed by HOMER 2.81 software and the study site is Shahrekord, the capital of Chaharmahal and Bakhtiari province. The results showed that the lowest cost per kWh of electricity generated for a system disconnected from the grid with a value of $0.251 related to the system including 8 kW solar cell, 1 kW diesel generator, 9 batteries and 2 kW electric converter that the effect of temperature on performance solar cells is included. For this superior scenario, 154 kg of CO2 emissions is generated annually because 3% of the required electricity is supplied by a diesel generator. Another point that can be seen from the results is that not considering the temperature in the performance of solar cells in the study area causes some errors in the calculations and increases the levelized cost of energy parameter. This issue has not been considered in many past works and the current work in this field has an advantage.
