Renewable hydrogen is a relatively new technological development. Traditionally, most of the world’s hydrogen has been derived from fossil fuels, such as coal or natural gas. Traditional production methods, such as steam reforming (where natural gas is treated with steam in the presence of a cat...
Hydrogen is a clean alternative to methane and is the most abundant chemical element, estimated to contribute 75% of the mass of the universe. Find out why hydrogen is important as a future clean energy source to fuel our homes and businesses.
COP26 brought together countries from around the world to discuss the next steps in a global response to climate change. At the 2021 conference in Glasgow, a new-old energy source dominated discussions of cleaner energy and decarbonization: hydrogen. To find out if hydrogen is one of the “...
Safety criteria for the storage of liquid hydrogen, liquefied natural gas (LNG) and gasoline are compiled and presented. Gasoline is believed to be the easiest and perhaps the safest fuel to store because of its lower volatility and narrower flammable and detonable limits. It is concluded that ...
Hydrogen is the first element on the periodic table. It is a very light gas with unique properties. Hydrogen has a low density and is colorless, odorless, and tasteless. It is highly flammable and can react explosively with oxygen. Hydrogen has many important uses. It is used as a fuel ...
