4 liter etanol per m3 naturgas, hur långt kan man köra på en m3 naturgas?
Spontant känns det inte lysande, det går ju åt en skvätt energi att producera majsen också.
Citat:
The facility will process 575,000t of corn to produce about 240 million litres (50 million gallons) of bioethanol per year. It will also produce about 175,000t of dried distillers grains with soluble (DDGS). DDGS is a rich protein feed for livestock and will partially replace the soy bean meal.
Citat:
A dry mill plant and power co-generation plant will be part of the facility. The co-generation plant will produce 15GWh of electricity which is about 40% of the total electricity requirement of the facility. The bioethanol plant will consume about 152,000m³ of natural gas per day.
240 miljon liter etanol ≈ 1409 GWh
152.000m³ naturgas = 1 687 200 kWh ≈ 1,7 Gwh
220 arbetsdagar/år * 1,7 Gwh = 374 Gwh
ca 400 GWh in och 1400 GWh ut
Man borde kunna göra de med biogas i stället, av drank kan man göra biogas. Eller använda restvärme från en biobränsle drivet värmekraftverk som Agretanol gör.
