Abstract
Hydrogen is notable for its unique properties making it the most viable alternative fuel for electricity generation and engine power. This element is highly abundant and is being used in numerous applications industrially. But hydrogen can be an important source of fuel and with the proper knowledge of its different technologies, innovations for hydrogen fuel production can then be addressed. Steam reforming of natural gas is the widely used hydrogen production technology. But environmentally safe production had been a pressing issue. Hence, a shift to a cleaner and more sustainable primary energy source is very essential. This paper gives brief background of the different hydrogen production techniques using two primary energy resources as well as the developments, the gaps, and the further improvements needed to be made. Note however, that comprehensive R&D details should be sought in specialist papers for a more thorough background. The sustainability of hydrogen production technology lies from where it is produced, thus this paper also aims to highlight the hydrogen fuel production from biomass citing its developments and its potential for high hydrogen yield.
