Brown Coal (lignite) is the lowest grade of coal. Lower density of carbon in the mix, and more impurities (pollutants) than bituminous coal or than anthracite.

That there is a renaissance of lignite is nothing short of amazing. It's like the tar sands being renamed oil sands.

Can the last politician to go out the revolving door please turn the lights off?

Nomad might tear his hairs out, but it appears there is a langage difference in terminology here, too. Lignite is the lowest grade of coal in all languages, but while it appears to be synonymous with brown coal in English, it is the youngest, shale-like form of Braunkohle in German -- and a separate, third grade in Hungarian...

Re: Brunsbüttel, Krümmel (German nuclear controver (4.00 / 2)
Interesting to compare languages by comparing the corresponding the grades and their heat content:

German:

wood: 17-20 MJ/kg
Lignit: 20-25 MJ/kg
'soft' Braunkohle: 25.1-26.8 MJ/kg
'hard' Braunkohle: -28500 kJ/kg
'flame' Steinkohle ( = stone coal): -32.85 MJ/kg
'gas flame' Steinkohle: -33.9 MJ/kg
'gas' Steinkohle: -35.0 MJ/kg
'fat' Steinkohle: -35.4 MJ/kg
'eating' Steinkohle: -35.4 MJ/kg
'lean' Steinkohle: -35.6 MJ/kg
anthracite: -36.0 MJ/kg

English:

lignite/brown coal: 10-20 MJ/kg
sub-bituminous coal: 20-28 MJ/kg (with most sold in the US near the lower limit)
bituminous coal: 24-35 MJ/kg
anthracite: 26-33(?) MJ/kg

Re: Brunsbüttel, Krümmel (German nuclear controver (4.00 / 2)
So apparently the main the difference is what brown coal refers to. While trawling Wikipedia for the English numbers, I also found that 'stone coal' in English is a less-used synonym for anthracite, "not to be confused with German Steinkohle"... (I'm seeing Nomad balding)

And yet (none / 1)
another reason why I don't want to work with coal.

I think that should be my next sig-line.

10-25 MJ/kg.

Let's see if I understand correctly: we are extracting from the earth something that potentially gives less energy than wood?

Well, tar sands are supposed to have the energy density of potatoes.

Peak oil is not an energy crisis. It is a liquid fuel crisis.

Hey, totally OT, but have you gotten my e-mails?  Our system is all berzerk at work and nothing's working properly.  Just want to know that you got them (and that I had the right address.)
