Hydrogen based energy are gaining interest as a suitable alternative energy source for usage and many researches are currently being engaged towards realizing a lasting hydrogen economy. However, in order to achieve this, it is important to have a hydrogen generation process that can efficiently compete with that of fossil fuel. Presently, majority of the hydrogen is being produced by steam methane reforming, a process that utilizes fossil fuel and emits greenhouse gases. Recent developments utilize non-thermal plasmas for reforming gas and liquid compounds containing hydrogen. Plasma micro reactor has the capability to produce energetic species from steam at atmospheric pressure which through a series of reaction combine to form hydrogen and oxygen. This method can be a potentially advantageous and cleaner method of producing hydrogen. Dissociation of steam using dielectric barrier discharge (DBD) plasma reactor at atmospheric pressure have been considered and is being tested for its hydrogen production yield. Atmospheric pressure plasma was generated using high frequency and high voltage pulse power supply. The hydrogen conversion rate is defined as the ratio of the total gas that entered the plasma reactor and the hydrogen concentration obtained from the resulting gas after decomposition. Hydrogen production was found to be dependent on the saturated steam flow rate and applied voltage of power supply.
