All of these. Coal gas is a mixture of many calorific gases such as hydrogen, methane and volatile hydrocarbon. Water gas is a mixture of carbon monoxide and hydrogen and liquid hydrogen is liquid state of element hydrogen which is

Hydrogen is a naturally occurring gas, and it is the most abundant substance in the universe. (The word in Greek means "water former" because hydrogen creates water when burned.) Clean hydrogen is hydrogen produced with very low or zero carbon emissions. The term also refers to derivative products of hydrogen, including

Hydrogen can be used for energy storage. Hydrogen storage is an important technology to enable hydrogen use across the U.S. economy. Hydrogen may be stored as a: Gas—Hydrogen can be stored as a gas in large volumes in natural geological formations—salt caverns, lined hard rock caverns, depleted oil and natural gas fields,

Hydrogen is a clean alternative to methane, also known as natural gas. It''s the most abundant chemical element, estimated to contribute 75% of the mass of the universe. Here on earth, vast numbers of hydrogen atoms are contained in water, plants, animals and, of course, humans. But while it''s present in nearly all molecules in living

So we generate some renewable electricity, we use that to make hydrogen which has a process of efficiency of about 80%. We might lose 20% of the energy that we''d had as electricity in making hydrogen. We then have to transport that hydrogen which takes some energy and then we have to burn that hydrogen in a boiler to heat water to
