Abstract

Today, hydrogen production largely comes from fossil fuels, which leads to various environmental problems, primarily global warming. Different energy sources are used for hydrogen production. The hydrogen production potential of a thermochemical cycle hydrogen production unit using vanadium chloride (V-Cl) was investigated by integrating a hybrid reactor. Additionally, the rate of hydrogen production in the hydrogen production facility integrated into the reactor was examined. The vanadium-chloride (V-Cl) thermochemical cycle was preferred as a method for hydrogen production. The approximate hydrogen production rate at the beginning and end of the 48-month operation period of the plant was calculated as ~14.95 kg/s and ~21.07kg/s. Furthermore, the total hydrogen production from the hydrogen generation plant integrated into the hybrid reactor during its 48-month operation period has been calculated as 2.53 x 10⁶ tons. As a result, it seems that the hybrid reactor and vanadium chloride (V-Cl) thermochemical cycle are preferable for hydrogen production.
