[edit] Emissions
In California, cogen plants are subject to permitting, to control their emissions of NOx and CO. There have been recent advances in very low NOX units.--Billymac00 01:42, 5 September 2007 (UTC)
[edit] Hatnote
I've redirected the hatnote to the disambiguation page. It's not doing any harm, but do we really need one? Most users entering "CHP" to find this article would arrive here via the disambiguation page, but not the other way round. --Old Moonraker (talk) 07:35, 30 December 2007 (UTC)
[edit] Efficiency
Aren't the efficiency numbers given a little misleading? It would be useful to see how the division between electricity and heat is for cogeneration. The amount of electricity that can be produced per input heat unit is reduced when the "waste heat" is used for space heating or anything other than dumping to the lowest temperature possible. Taken to the extreme, it would indicate that we should just burn gas for heating, it gives an efficiency of 98% after all. But, if the gas was instead burned in a combined cycle gas turbin to generate electricty at 60% efficiency, the electricity could be used to drive heat pumps for heating and give a 180% efficiency (if the heat pumps operate with a COP of 3). Is the total efficiency of cogeneration really better than a CCGT driving heat pumps for space heating?(Matthew.homola (talk) 17:54, 17 April 2008 (UTC))
