Question

How to generate hydrogen with sustainable energy? Is it possible to have a power system with zero emission?Explain

Answer 1

Most of the world's Hydrogen Production Result from Steam Methane Reforming. At high temperatures (700 – 1100 °C) and in the presence of a metal-based catalyst (nickel), steam reacts with methane to yield carbon monoxide and hydrogen.But it Is Not sustainable as it requires high amount of energy and Catalyst .

Other method is Electrolysis Of water

Electrolysis is a promising option for hydrogen production from renewable resources. Electrolysis is the process of using electricity to split water into hydrogen and oxygen. This reaction takes place in a unit called an electrolyzer whic can be small medium or large depending upon production

It is the most Sustainable method with zero green house emission as only electricity is required for producing Hydrogen gas But the paradox is that only 4% of world's Hydrogen Production takes place through this method as because most of the electricity is generated using technologies that result in greenhouse gas emissions and are energy intensive.

But if the electricity can be produced from renewable resource like Wind energy , solar , geothermal , ocean energy Electrolysis can be The most Viable and Sustainable Methods with zero emissions .

But for This a strong Will is required by world big democrats as well as common people to save our Planet earth form Global warming byl looking at sustainable energy sources like Hydrogen whic have high efficiency and are eco-friendly.
