Abstract

The development of renewable energy and hydrogen is a vital strategy for achieving the goals of "carbon peak and carbon neutrality". With utilizing renewable energy for electro-hydrogen conversion and employing hydrogen storage

the electric-hydrogen coupling system is poised to play a pivotal role in the future energy framework

serving as one of the key drivers in the evolution of new power systems. This paper presents the concept and essential characteristics of the electric-hydrogen coupling systems

elucidating key technical aspects such as resource analysis

technology selection and optimization

and energy management in the construction of these systems facing industrial areas. It further examines the distinctive interaction features of the electric-hydrogen crucial subsystems (such as electrolyzer

fuel cell

hydrogen storage system

electric-hydrogen DC converter

and energy management)

and their critical roles in ensuring long-term safe and stable system operation. Finally

grounded in the current demands of the power grid and the technology level of key equipment

the paper forecasts the future development of electric-hydrogen coupling systems

offering practical insights and reference for the broader application and advancement of electric-hydrogen coupling technologies.
