Metan: Skryt\u00fd zdroj energie<\/h2>\n\n

Metan, siln\u00fd sklen\u00edkov\u00fd plyn, se \u010dasto uvol\u0148uje jako vedlej\u0161\u00ed produkt p\u0159i t\u011b\u017eb\u011b uhl\u00ed.

Pokrok v technologi\u00edch, jako jsou nanop\u00f3ry zeolity, v\u0161ak umo\u017e\u0148uje odfiltrovat ne\u010distoty a extrahovat metan i z velmi z\u0159ed\u011bn\u00fdch zdroj\u016f.<\/p>\n\n

Tento projekt zachycuje metan z ventila\u010dn\u00edch syst\u00e9m\u016f a vyu\u017e\u00edv\u00e1 ho k v\u00fdrob\u011b elekt\u0159iny, kter\u00e1 je pot\u00e9 dod\u00e1v\u00e1na do m\u00edstn\u00ed elektrick\u00e9 s\u00edt\u011b. Projekt Elk Creek demonstruje potenci\u00e1l metanu jako obnoviteln\u00e9ho zdroje energie a inspiroval podobn\u00e9 projekty po cel\u00e9m sv\u011bt\u011b.<\/p>\n\n

Nap\u0159\u00edklad kalifornsk\u00fd program typu cap-and-trade odm\u011b\u0148uje spole\u010dnosti za sni\u017eov\u00e1n\u00ed emis\u00ed sklen\u00edkov\u00fdch plyn\u016f, v\u010detn\u011b emis\u00ed metanu. Krom\u011b toho Agentura pro ochranu \u017eivotn\u00edho prost\u0159ed\u00ed identifikovala slibn\u00e9 uheln\u00e9 doly pro projekty zachycov\u00e1n\u00ed a p\u0159em\u011bny metanu.<\/p>\n\n
