What Is Hydrogen Energy?
Hydrogen is a clean-burning fuel that produces only water as a byproduct, making it an environmentally friendly alternative to fossil fuels. This article will explore the benefits and drawbacks of hydrogen power, its potential uses, and the challenges that need to be addressed before it can become a mainstream energy source.
Hydrogen Fuel Basics
Hydrogen is an energy carrier that can be used to store, move, and deliver energy produced from other sources. Today, hydrogen fuel can be produced through several methods. The most common methods today are natural gas reforming (a thermal process), and electrolysis. Other methods include solar-driven and biological processes.

Hydrogen
Når hydrogen reagerer og binder seg til andre atomer frigjøres energi. Energien til hydrogen ligger altså i denne tendensen til å reagere med andre atomer. Stort sett har hydrogen allerede bundet seg til et annet stoff i naturen, og det finnes derfor ikke fritt hydrogen på jorda eller i atmosfæren vi kan bruke til energiproduksjon.
