Title: What makes Micro CHP green?
Post by: allegrif on December 03, 2015, 03:32:32 PM
If the system explicitly burns methane and releases CO2 as part of its core process, why do people say it's green? Aren't those the very two gases we're looking to avoid releasing into the atmosphere?

Burning methane is good, because co2 is less harmful, and you're getting energy from it. Also MicroCHP systems are more efficient and generate more energy for the amount of fuel burned.

But where does the methane come from? If we're essentially farming methane to use in this process - methane that normally would be trapped and dormant somewhere - then we're releasing excess greenhouse gases in the form of CO2 aren't we?
