By 2010 or so, the company hopes to be producing ethanol commercially for 80 cents a gallon at wholesale. That could translate to anywhere from $1.10 to $1.50 at the pump, depending on a host of factors

Other approaches have theoretical restrictions that limit ethanol production to 60-100 gallons per dry ton of biomass. The ZeaChem technology will produce fifty percent more ethanol per ton of feed than the current best-in-class technology.
((60 * 1.1023) * 3.7854) * 150% = 375,5428 liter / 1000 kg
((100 * 1.1023) * 3.7854) * 150% = 625.9046 liter / 1000 kg
375-625 liter etanol per ton torr massa
det motsvarar 2201-3 669 kWh / ton torr massa, inte illa!
Som jmf innehåller 1000 kg bra pellets är ca 4800-5000 kWh
Undrar hur mkt energi processen kräver.
