In the wave of global energy transition, islands and remote areas often face unique challenges, as these regions usually struggle to obtain stable traditional energy supplies. Relying on fossil fuel-based power generation not only incurs high costs but also negatively impacts the environment. As the global energy transition and carbon neutrality goals progress, hydrogen microgrids have become a key solution for stable green power supply. Due to the intermittency of solar and wind energy, it is difficult to provide consistent power solely through renewable sources. Thus, hydrogen microgrids have emerged, combining hydrogen fuel cell power generation, lithium battery short-term storage, and water electrolysis for long-term hydrogen storage. This system stores excess renewable energy as green hydrogen, which can then provide stable and clean electricity during peak times or when the grid is down. Compared to traditional diesel generators, hydrogen microgrids offer zero carbon emissions and can address the instability of renewable energy supply, ensuring stable power even during severe weather or power outages. This technology is especially effective in islands and remote areas, utilizing local renewable energy to achieve energy self-sufficiency, reducing dependence on external energy sources, and providing long-term storage capacity to ensure energy stability and support local economic and social development.
