N2 - Hydrogen (H
2
) is considered as a clean source of energy and energy carrier for various applications due to its high energy density. H
2
can be used in various applications such as; electricity generation, in H
2
Fuel Cell electric vehicle, in processing and manufacturing industries
and most promisingly in energy transportation applications. This leads
to increase in demand of H
2
around the globe. Naturally, H
2
exists with different hydrocarbons such as; methane (CH
4
), propane (C
3
H
8
), ethane (C
2
H
6
) and currently significant part of H
2
production comes from coal and natural gas. The current system uses gasification to generate H
2
and emits carbon dioxide (CO
2
), nitrogen oxide (NOx) and other toxic gases to the environment.
Besides, most of the electricity is currently produced from coal fired
plants which also contribute to greenhouse gas emissions and
environmental pollution. This paper presents a coal gasification model
in terms of increased H
2
production and emission reduction. This increased H
2
can be used in distributed power generation applications. In order to
do that the operational conditions of gasification have been
investigated including; temperature and gasifying medium. The results
showed that, with rising temperature H
2
production increases from 1.78E-11 kg/hr to 2.21 kg/hr at 2,000°C while CO
2
emission dropped from 8,364.11 kg/hr to 8,027.21 kg/hr. Furthermore, the steam and air agent is found favourable for higher H
2
production and reduction in CO
2
emission. As found, H
2
production increases up to 734.13 kg/hr and CO
2
emission declines to 7,210.64 kg/hr. Therefore, the temperature and
steam and air agent can significantly improve the coal gasification
performance.
