Cogasification of biomass and coal is an alternative that increases the reliability of power plants while reducing CO 2 emissions [125]. Cogasification of biomass and coal has exhibited a synergistic effect, with many studies reporting that with higher amount of biomass the gasification reaction was promoted [125], [126], [127].
