Decarbonizing power generation is accomplished through coupling renewable energy with long term energy storage, primarily through the use of a hydrogen electricity coupling system. This paper considers the effectiveness in mitigation of carbon emissions, power quality enhancement and balancing supply demand variability of such systems. Smoothing of energy availability over time is achieved when we store hydrogen, and the initial carbon emissions decrease when we install it. Power quality metrics such as voltage stability, harmonic distortion, and reactive power management are acceptable in the system and the system is technically viable. The findings reveal a potential of mid-century carbon neutral goals are revealed by hydrogen as a reliable energy vector. Basically, the study gives a hydrogen-electricity coupling model that integrates wind, solar, biomass, and other renewable energy sources, hydrogen production, storage, and grid power delivery as one operational structure. The simulations conducted on MATLAB/Simulink showed with good quality and fast response that the system possessed stable power quality and performed energy conversion efficiently with whatever the variable renewable input conditions were.
