"Compressed air is not a fuel, but a means of storing energy. It is not accurate to call it emissionless, as emissions will depend on how the air is compressed."
--> Fuel is any material that stores energy that can later be extracted to perform mechanical work in a controlled manner. ref=http://en.wikipedia.org/wiki/Fuel So, compressed air is definitly a fuel. As for not being emissionless; that's how you interpret it, I'm focusing on only the emissions during operation, not the emissions for the entire energy storage/use cycle. 91.182.254.115 03:49, 19 October 2011 (PDT)
- I'd be careful about relying on a very literal interpretation of some words in a Wikipedia article, where it goes against common usage. Are you aware of other sources talking about compressed air as a fuel? I might be wrong, but I don't think it's a regarded as a fuel.
- Not that I want to be too pedantic... but it's significant to distinguish between actual sources of energy (fossil fuel, biofuel...) and means of transporting/storing energy (compressed air, or battery power, or hydrogen made from solar or wind).
- "I'm focusing on only the emissions during operation" - fair enough, and it's a significant difference if there is some way of capturing CO2 at the point where the energy is produced (e.g. power station). Could you please clarify the use of "emissionless", either in the column header or in a footnote? Thanks. --Chriswaterguy 09:29, 12 March 2012 (PDT)
