Title:
METHOD FOR ELECTROLYSIS OF WATER TO PRODUCE HYDROGEN TAKING FLUCTUATING POWER INPUT AND APPARATUS FOR SAME
Document Type and Number:
WIPO Patent Application WO/2022/012697
Kind Code:
A1
Abstract:
A method for electrolysis of water to produce hydrogen taking a fluctuating power input and an apparatus for same, the method comprising: allocating a fluctuating input power into an electrolysis power and a thermal storage power; the electrolysis power being used to provide electrical energy for electrolysis of water to produce hydrogen; and the thermal storage power being converted into thermal energy to provide starting energy for electrolysis of water to produce hydrogen, in order to increase the cold start speed of electrolysis of water to produce hydrogen. The apparatus comprises: a power adjustment module, used to allocate the fluctuating power input into an electrolysis power and a thermal storage power; a hydrogen producing module, connected to the power adjustment module in order to use the allocated electrolysis power to perform electrolysis of water to produce hydrogen and oxygen; and a thermal storage module, connected to the power adjustment module in order to convert the allocated thermal storage power into thermal energy, the thermal energy being inputted into the hydrogen producing module in order to improve the cold start speed of electrolysis of water to produce hydrogen.
