TECHNICAL AND ECONOMIC MODEL OF AN AUTONOMOUS COMPLEX FOR PRODUCTION OF «GREEN» HYDROGEN AND ITS TESTING ON THE EXAMPLE OF MONGOLIA AND JAPAN

Abstract

The relevance. The paper presents a technical and economic model of a liquefied hydrogen production complex supplied only by renewable energy. The model compares technical and economic indicators of «green» liquefied hydrogen production in different locations subject to their climate, technical and economic conditions. The unique characteristic of the proposed model is that it considers the main technological processes for hydrogen production, conversion and storage, taking into account the annual hourly profile of possible renewable energy generation and shipping schedule of liquefied hydrogen as a commercial output. Employing the model will be relevant at the stage of pre-feasibility studies devoted to the creation of hydrogen energy productions in regions with high renewable energy potentials and remote from power infrastructure and allow enhancing reasonableness of estimations when taking investment decisions. The main aim: to develop a technical and economic model of such a complex and to test it by estimating the levelized cost of «green» liquid hydrogen for selected locations in Mongolia and Japan. Object: the autonomous complex for production of «green» hydrogen. Methods. The model is based on an optimization problem that determines the level and structure of costs born to produce liquefied hydrogen using solar and wind energy. Results. For verification of the model the comparative estimations for production of 10000 tonnes per year of the liquefied «green» hydrogen were calculated. The costs for locations in Mongolia (east coast of Lake Hubsugul) and Japan (coastal areas of Yamagata Prefecture) amount to $10,8 per kg and $13,4 per kg, respectively.
