Vattenfall took over HEW in 2000. So it was a Vattenfall problem at the time of the 2001 hydrogen incident already.

As a Swede I'm appalled at how two-faced Vattenfall is. At home it's all about hydroelectricity, renewable, yada yada. In reality there's increasing amounts of coal in the mix.

(Perhaps someone can explain why "brown coal" is worse than "coal"? Extraction methods?)

It's interesting to listen to the way this company uses the words "Europe" and "European" - in many ways it's similar to the way they are used in the USA when talking about early US history: old-fashioned, bad, unenlightened and certainly not our responsibility.

(Wikipedia links to an article here - in Swedish, sorry - that sadly I don't have time to translate right now.)

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.

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...

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

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)

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.)
