DESALINATION OF SEA WATER FOR PRODUCTION OF GREEN HYDROGEN

Keywords: offshore wind power, hydrogen energy, electrolysis of water, desalination of sea water.

Abstract

The problem of development of offshore wind energy in Ukraine is the need to create an efficient system of fresh water supply for the production of green hydrogen by electrolytic method. The use of hydrogen technologies allows to optimize the operation of the wind power system and achieve greater economic efficiency of wind power equipment, as it ensures the continuity of the generating wind power plant.

Ukraine's participation in the European program "2x40 GW Green Hydrogen Initiative", according to which Ukraine envisages the installation of 10 GW of new capacities for the electrolytic production of green hydrogen, requires detailed development of appropriate marine wind farm infrastructure, especially seawater desalination systems to reduce logistics costs on its delivery.

The analysis of modern desalination methods is carried out and it is determined that the most acceptable method today is reverse osmosis, which has significant advantages: relatively low operating costs, simple and compact design. The operation of such a system can be easily automated, so they are controlled in a semi-automatic and automatic mode.

It is established that the operation of a 1 MW electrolytic cell together with a desalination system is provided by an offshore wind farm with a capacity of 2 MW. The calculated indicators presented in the paper are indicative and are recommended for use as preliminary initial data in the development of specific projects of different capacity, which will be specified taking into account all factors - characteristics of sea water, wind, electrolytic and desalination equipment to obtain green hydrogen, etc.

Large-scale production of electrolytic hydrogen using offshore wind energy will change the structure of Ukraine's fuel and energy complex by increasing wind energy, increasing the stability of wind power equipment, efficiency and reliability of electricity supply, and will have a positive impact on the environment.
