secondary energy source

Page history last edited by Andrew Alder 2 years, 5 months ago

A secondary energy source is one that is derived from another source or sources. I would prefer to use the term derived energy source as more generally recognisable. It seems to mean the same thing, but secondary energy source is the normal term.

The main secondary or derived energy source is electricity.

There is much interest in hydrogen as a secondary energy source, and has been for many years. Replacement of other energy sources by hydrogen was once promoted as the hydrogen economy, and it still has a following. The term hydrogen economy was again popularised by the 2002 book The Hydrogen Economy: The Creation of the Worldwide Energy Web and the Redistribution of Power on Earth in 2002 by Jeremy Rifkin.

Converting electricity into hydrogen has particularly little to recommend it. There are better ways of storing and distributing electricity, and it's a lot more useful than hydrogen. We might call the hopes that electrically-generated hydrogen will somehow help to reduce the use of fossil fuels Hyprogen.
