can anyone of you tell me what is the industrial price for methane? (by industrial I mean using something like 0.3kg per second....)
`can you tell me a reference where I can find prices for the most common feedstock?
In the U.S. this will vary a lot, depending on the state. A good U.S. average price is 4 US$ per 1000 cubic feet of natural gas (essentially methane). This is for industrial consumers.
