Investigation of thermal processes in hydrogen-oxygen steam generators of kilowatt power class

Abstract

THE PURPOSE. To analyze the current state and prospects for the hydrogen energy development. To consider the possibility of implementing a project aimed at producing hydrogen on the territory of the Republic of Crimea. To choose a suitable location for the facility construction. To provide for the use of renewable sources to supply consumers of the facility with electricity. To study the existing methods of obtaining hydrogen in order to select the suitable one for use on the territory of the Republic of Crimea. To calculate the amount of electricity generated by the selected source and consumed by the elements of the hydrogen production system. To determine the cost of the project and its payback period. METHODS. The method of calculating the amount of electricity generated by the source, as well as the method for determining the cost of project implementation and payback based on data from open sources were used to achieve the set goals. In this work, a simulation of a facility consisting from an electricity source – a solar power plant with an installed capacity of 110 MW, a hydrogen production system – an electrolyser with a capacity of 50 MW, a seawater desalination system – a reverse osmosis unit with a capacity of 600 tons of water per day was performed. Various types of electrolysers were analyzed. RESULTS. The balance of energy generated and consumed by the elements of the hydrogen production system was determined. The capital costs of implementation and the annual operating costs of the project were calculated. CONCLUSHION. The recoupment of such a project, according to preliminary estimates, will be from seven to eight years with a capital investment of about five billion rubles.
