the numbers you cite, even though they come from the same Wikipedia page, are absolutely inconsistent. If the Germans announce their most recent power plants with efficiencies above 40%, it is because they have obtained them, which is probable with steam temperatures above 600°C.
As for the 0,3kWh/kg for pellets, I wondered if this was not the quantity of electricity needed to manufacture 1kg of pellets (grinding, granulation, etc.). But you have the source, I don't know how to verify it.
PS for Ahmed: du lignite, not for the lignite, which does not change anything in the PCI.
Absolutely ! This data is completely inconsistent: 90% of the energy produced is lost but the efficiency is very good...
. It's Wikipedia, anyone can contribute as long as there are links. Wikipedia is very good, you just have to sort it out and take certain things with a pinch of salt.
1 kg of coal/lignite producing 1 kWh of electricity is about the average for German power plants. The USA does better, on average there, it is 2 kWh for 1 kg of coal.
For Cordemais pellets, it is in the PDF published by EDF which takes stock of Ecocombust Phase 1. It gives the quantity of pellets consumed by Ecocombust Phase 1, then the quantity of electricity produced by this tonnage of pellets. . Just do a division. This is not good ?
N.B.: I come to Ahmed's aid by pointing out that there is hesitation about the gender of the word "lignite". Using the feminine is therefore not a mistake. A link about this:
