Abstract

This paper addresses the inherent energy potential of hydrogen generated as a byproduct in a sodium chlorate production plant, emphasizing the existence of a significant surplus that is released into the atmosphere. Different technological options aimed at efficiently utilizing this surplus hydrogen are presented and discussed, covering areas such as energy storage, sustainable mobility, as well as Power-to-Gas and Power-to-Liquid technologies. With the objective of elucidating the potential economic and social impact of each approach, while taking into account the regional peculiarities inherent to the manufacturing plant. The results obtained indicate that the integration of hydrogen as a clean energy source can optimize operational efficiency and reduce the carbon footprint associated with sodium chlorate production. Consequently, this leads to increased energy autonomy for the facility and contributes to the principles of environmental sustainability. The study emphasizes the potential of hydrogen as a valuable and sustainable resource, promoting benefits for both the industrial sector and the environment. It is important to note that the production process generates a significant amount of waste, with an estimated annual volume of 750 tons. This highlights the need to implement efficient waste management practices and avoid unnecessary waste of this crucial energy carrier. By minimizing waste and maximizing the utilization of hydrogen, we can further enhance the economic and environmental benefits associated with its production and utilization.
