Hydrogen energy is a clean and efficient energy source that could be crucial for energy transitions in Eastern Asia and the MENA region. Researchers reviewed different technologies for producing, storing, and using hydrogen. They found that solid polymer electrolyte electrolysis and solid material storage are promising methods for hydrogen production and storage. They also suggest promoting technologies like hydrogen fuel cells and natural gas-hydrogen mixtures for use. By combining various technologies, renewable energy hydrogen production can become more cost-effective and easier to transport. Overall, hydrogen energy has great potential for creating integrated energy service parks in the future.
