Unugyada shidaalka ee haydarojiinta waxay isticmaali karaan noocyo badan oo shidaal iyo quudin ah
Tobanaan waddan ayaa ballanqaaday inay gaaraan yoolalka qiiqa eber tobanaan sano ee soo socda. Haydarojiin ayaa looga baahan yahay inay gaaraan yoolalkan qoto dheer ee kaarboonaynta. Waxaa lagu qiyaasaa in 30% qiiqa CO2 ee la xiriira tamarta ay adag tahay in la dhimo iyadoo la adeegsanayo korontada oo keliya, taasoo siinaysa fursad weyn oo ay ku heli karaan haydarojiin.
