Abstract

The invention provides a renewable energy hydrogen production and hydrogen storage system and its control method. The system includes a renewable energy power generation subsystem, a water electrolysis hydrogen production subsystem, a heat tracing subsystem and an organic hydrogen storage subsystem, wherein, The heat tracing subsystem is connected between the organic matter hydrogen storage subsystem and the water electrolysis hydrogen production subsystem, and part of the heat generated when the organic matter hydrogen storage subsystem generates hydrogenated organic matter is transferred to the water electrolysis hydrogen production subsystem through the heat tracing subsystem. Water electrolysis hydrogen production device heating. This scheme uses the heat generated when hydrogen reacts with organic matter to heat the water electrolysis hydrogen production device to ensure that the liquid in it will not freeze or crystallize in cold seasons. While ensuring the safety of the system, it can reduce the next startup time, thereby Improve the production efficiency of water electrolysis hydrogen production device. At the same time, part of the heat of the hydrogenated organic matter is used to heat the water electrolysis hydrogen production device, which reduces the amount of cooling water required for cooling the hydrogenated organic matter and improves the energy utilization rate of the system.

Description

technical field [0001] The invention belongs to the technical field of hydrogen production by renewable energy, and in particular relates to a hydrogen production and storage system and a control method thereof. Background technique [0002] In recent years, renewable and sustainable energy represented by photovoltaic power generation has developed rapidly, but the intermittent and unpredictability of renewable energy power generation has become a huge obstacle to realize large-scale integration into the main power grid. For renewable and sustainable energy systems, hydrogen is an excellent energy storage medium, which can convert solar energy with strong fluctuation characteristics into hydrogen energy, which is more convenient for storage and transportation. [0003] However, the current hydrogen production and storage systems do not take into account the renewable energy hydrogen production and storage systems, especially the comprehensive utilization of the heat in the s...
