 D'un c\u00f4t\u00e9 la Grand-messe danoise avec des milliers de d\u00e9l\u00e9gu\u00e9s qui ne savent pas trop pourquoi ils sont l\u00e0, sinon pour faire nombre. Tout cela pour d\u00e9finir de vagues objectifs aux \u00e9ch\u00e9ances lointaines, sans grande ligne politique, sans choix strat\u00e9gique, sans plan d'action. D'un autre c\u00f4t\u00e9 le business quotidien qui continue, "as usual": Alstom vend une centrale au charbon de 600 MW \u00e0 la Slov\u00e9nie. "Ce contrat aura par ailleurs un fort impact local, en permettant de maintenir \u00e0 pleine capacit\u00e9 la production de la mine de charbon voisine (qui aurait \u00e9t\u00e9 autrement r\u00e9duite de moiti\u00e9)" affirme gaillardement le communiqu\u00e9 d'Alstom. L'\u00e9quipement install\u00e9 comportera "une chaudi\u00e8re \u00e0 tour \u00e0 passage unique, pr\u00e9sentant des param\u00e8tres de vapeur ultra-supercritiques." Tel finit le communiqu\u00e9. On aurait aim\u00e9 conna\u00eetre les rejets de CO2 de cette nouvelle tranche, son impact sur le monde. Ultra-supercritique, cela signifie des temp\u00e9ratures vers les 600\u00b0C et des rendements de l'ordre de 45%. Alors il faut s'attendre \u00e0 des rejets de CO2 vers les 900 kg\/MWh nous indique la thermodynamique (FIG.), peut \u00eatre moins (760 kg\/MWh) si l'on tient compte de la teneur en hydrog\u00e8ne du charbon (4%), mais allez-savoir? Le communiqu\u00e9 est muet sur la question. Alors, il ne reste plus qu'\u00e0 compter:<\/p>\n

600MW x 8760 heures x 80% de taux de charge x 0,76 T\/MWh = 3,2 milliards de tonnes de CO2 par an\u00b0<\/span><\/strong>. <\/p>\n

\u00b0(Valeur revue \u00e0 la suite de la remarque de Lucas et de la prise en compte de 4% d'hydrog\u00e8ne que j'assimile thermodynamiquement \u00e0 16% de m\u00e9thane et non pas \u00e0 5%. Mais la valeur r\u00e9elle<\/span> des \u00e9missions d'une centrale doit \u00eatre bien sup\u00e9rieure \u00e0 ce calcul th\u00e9orique si l'on tient compte des phases durant lesquelles la centrale ne fonctionne pas \u00e0 son r\u00e9gime optimal en raison de baisses de charges, d'arr\u00eats et de red\u00e9marrages)<\/em><\/p>\n

Vous me direz, 3,2 milliards de tonnes de CO2 cela ne fait m\u00eame pas un milli\u00e8me des \u00e9missions de l'Europe, alors personne n'y verra que du feu. M\u00eame pas les d\u00e9l\u00e9gu\u00e9s du GIEC \u00e0 Copenhague. Alors pourquoi tout ce foin?<\/p>\n

FIG. O\u00f9 il est montr\u00e9 qu'il vaut mieux br\u00fbler du gaz naturel avec des centrales \u00e0 cycle combin\u00e9 \u00e0 60% de rendement, plut\u00f4t que du charbon dans des centrales ultra-supercritiques \u00e0 45% de rendement. La courbe discontinue verte tient compte d'un gaz naturel contenant avant purification 20% de CO2<\/span><\/strong><\/p>\n
