Biodiesel (none / 0)

Rapeseed

total area: 4.5 Mha
yield : 1100l/ha
4.5 x 1100 = 5 Gl biodiesel

Sunflower

total area: 2.2 Mha
yield: 1000l/ha
2.2 x 1000 = 2.2 Gl biodiesel

Total biodiesel from crops: 7.2 Gl

Re: Biodiesel (none / 0)

Rapeseed is given at 100% self-sufficiency, meaning all oil production is used within the EU, no surplus.

Sunflower seed has 109% self-sufficiency.

Not much room for an increase without greatly increasing area. Replacing what?

But al large fraction of the oil could be recycled. Double bang for the buck.

Re: Biodiesel (none / 0)

According to my calculation above, diesel consumption was about 170 Gl per year. 7.2 Gl is 4% of 177 Gl. Biodiesel by itself won't be able to attain the 5.75% share even if all the oil is recycled. [How about olive oil? In Portugal, Spain, Italy and Greece a lot of it is used for cooking and could be recycled]

Re: Biodiesel (none / 0)

7.2 Gl is the total current production, not the share available for biodiesel. Some of current production must go into biodiesel, but it's marginal. To get to 5.75% biodiesel, there would have to be very considerable increase in area. At some other crop's expense.
