The Efficient Electricity Storage Device with Hydrogen using DC Link and its Design Method

Abstract

The design method of hydrogen electricity storage system is presented. The various electricity storage requirements are classified to 3 steps, according to the amount of renewable energy introduction. The hydrogen electricity storage system is the most cost effective in the step 3, where renewable energy is introduced as a main power source. Then DC link wind power and alkaline electrolysis hydrogen production cooperating system design and its control system with small battery to suppress the renewable energy output fluctuations is presented.
