In the following summary, we provide a list of ten Chinese green hydrogen companies which are–in our view–with the most potentials to become the Chinese market leaders and the likely partners. Their energy strategy and recent green hydrogen moves are
In order to facilitate the integration of renewable energy sources into China's grid system, the present research assesses the practicability of hydrogen energy storage.
Hydrogen storage is a potential long-term strategy for grid stability because, despite its lower efficiency (50 %), it offers a greater energy density (120 MJ/kg) and can store energy for months. Table 3. Energy storage technology cost comparing. 5. Discussion
Comparison of hydrogen storage with other energy storage technologies. Hydrogen energy storage offers a practical way to address energy curtailment and enhance grid stability. The primary performance indicators for storage of hydrogen, lithium-ion batteries, and pumped hydro storage were previously detailed in Table 2.
By reducing the impact of renewable energy sources' unpredictability, improving frequency control, and supplying backup power in the event of supply deficiencies, hydrogen energy storage helps keep the grid stable. Energy curtailment is the practice of reducing or restricting the generation of power from renewable sources.
Converting extra energy into hydrogen at peak production times guarantees energy storage during low-output intervals . This capacity not only reduces energy waste but also improves grid stability, making hydrogen storage vital for China's energy transition and carbon neutrality objectives.
While there is an increasing demand for hydrogen energy storage (HES), there has been limited research on the viability of HES within important renewable energy zones in China .
