Hydrogen energy storage is a promising way to store energy because it's cheap, holds a lot of energy, and doesn't pollute. In China, the hydrogen energy industry is growing with government support. Scientists are improving how we make hydrogen from water through electrolysis, a process that uses electricity to split water into hydrogen and oxygen. They are working on making the materials that help with this process more efficient and cost-effective. This research aims to develop better ways to produce hydrogen from water, making it more accessible and efficient in the future.
