the latest technology is the the gasification of coal which
will produce syngas,consists primarily of hydrogen, carbon
monoxide,and has less than half the energy density of
natural gas .First this gas will drive the gas turbines and
then by heat exchanging method steam is generated and the
steam will drive the steam turbines later. This method
improves the thermal and overall efficiency of coal power
plants....and heat or energy waste can be avoided
