Abstract

A solution is provided for CO₂ and other green houses gas reduction at the Coal Fired Power Plants (CFPP). The methods and devices disclosed herein provide an inexpensive source of hydrogen and a hydrogen generating system powered by on-site excess heat generated at the CFPP without producing additional CO₂ emission.
