Hydrogen also solves the problem of energy storage. The sun doesn’t shine at night, and the wind doesn’t always blow. But excess hydrogen can be converted into hydrogen and stored for years. Then, it can be used in fuel cells to generate electricity.
There are alternatives: ammonia (easier to store) and synthetic fuels (e-fuels). But hydrogen is the cleanest.
The key challenge is infrastructure. New pipelines, refueling stations, and engines are needed. But Germany, Japan, and Australia are already investing billions.
Science is also exploring biological approaches: hydrogen bacteria and algae. Perhaps the future lies in rooftop bioreactors.
But the key is systems thinking. Hydrogen won’t save the world on its own. It’s part of an ecosystem: renewable energy + batteries + hydrogen + energy efficiency.
Climate science is clear: we have 10-15 years to avoid catastrophe. Hydrogen is not a panacea. But it is one of the keys.
In conclusion, green hydrogen is not a technology. It is hope, transformed into molecules. And if humanity unites, we can make it a reality.
