The idea of using air as an energy carrier is not new.

Heat is transferred to and from matter by the principal energy carriers.

Hydrogen is not an energy source, but rather an energy carrier.

Finally, urine can also be used as a basis to generate hydrogen (which is an energy carrier).

In this case, the carbon dioxide is given economic value as a component of energy carrier.

Both have in common that they are typically based on combustion of primary energy carriers.

They must be available to society to enable the production of energy carriers.

Electrolysis is an important new technology for the production of hydrogen to be used as an energy carrier.

Methanol is also a good energy carrier, being less volatile and easier to store than hydrogen.
