Hydrogen gas

Hydrogen, or H₂, is getting a lot of attention lately as governments in the U.S., Canada and Europe push to cut their greenhouse gas emissions. But what exactly is H₂, and is it really a clean power source? I specialize in researching and developing H₂ production techniques. Here are some key facts about this versatile chemical that could play a much larger role in our lives in the future. So, what is hydrogen? Hydrogen is the most abundant element in the universe, but because it’s so reactive, it isn’t found on its own in nature. Instead, it is typically bound to other atoms and molecules in water, natural gas, coal and even biological matter like plants and human bodies. Hydrogen can be isolated, however. And on its own, the H₂ molecule packs a heavy punch as a highly effective energy carrier. It is already used in industry to manufacture ammonia, methanol and steel and in refining crude oil. As a fuel, it can store energy and reduce emi...
