This work examines the viability of green
hydrogen production using solar energy and its incorporation into Sivas' public
transportation network in Türkiye. Being in the Central Anatolia region, Sivas receives
an average daily solar irradiance of 4.5 kWh/m²/day and daily sunshine for 7.2
hours, making it an appropriate place for solar energy systems. A 1 MWp solar
(PV) system has been simulated to generate approximately 1,191 MWh of
electricity annually. The electricity is used to power a proton exchange membrane
(PEM) electrolyzer to generate approximately 23.8 tons of hydrogen a year. The
hydrogen is sufficient to power approximately four fuel cell buses in the city.
Environmentally, this changeover from diesel to hydrogen fuel cell buses would
mean a reduction of about 359 tons of CO₂ emissions annually. Economically, the system capital cost has been
estimated to be €2.6 million, while €52,000 is an annual operational expense.
The LCOH has been found to be around €7.6/kg, and the payback period has been
calculated to be 13.6 years on the basis of revenue from the sale of hydrogen.
The proposed model can be a replicable template for medium-sized cities wanting
to deploy sustainable and low-carbon mobility systems.
