Why is hydrogen storage important in China?

According to the results, hydrogen storage is essential for China's transition to renewable energy sources and carbon neutrality targets despite efficiency issues. This is due to its large capacity and ability to store energy for extended periods of time. Fig. 2.

How does hydrogen energy storage compare with other energy storage technologies?

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.

Why is hydrogen a key energy storage technology?

The chart highlights hydrogen's essential function in enhancing other technologies to establish a stable and dependable renewable energy grid, particularly in extensive applications like China's energy transformation policy. Table 2. Comparison of hydrogen storage with other energy storage technologies.

Is hydrogen storage a long-term strategy for grid stability?

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

What are the benefits of hydrogen technology in China?

Hydrogen (120 MJ/kg) outperforms lithium-ion batteries (0.4 MJ/kg) for long-term energy storage. Hydrogen technology investments support grid resilience, economic growth, and long-term energy stability. China's goal to reach carbon neutrality by 2060 has driven significant investments in renewable energy.
