“…The simulation analysis of argon‐water vapor plasmolysis is carried out by combining the water vapor plasmolysis reaction model and argon reactions 14,40‐43 . Rehman et al 14 model is the basis model of this DBD simulation study; additionally, same initial conditions are assumed like electron temperature (T e ) of 3 eV. Moreover, the electron density in range of 1 × 10 18 ‐1 × 10 20 m −3 has been used in DBD plasma 44 .…”

A simultaneous investigation of simulation and experimental analysis of hydrogen production from argon‐water vapor mixture as a function in DBD plasma applied voltage were studied. The H2 concentration results of two Ar‐H2O simulation kinetics models were compared with the experimental results. The simulation analysis was implemented for Ar‐H2O models with and without the dissociative attachment reaction (H−). The effects of argon flow rate, input water vapor temperature, and water vapor flow rate on the H2 concentration from the Ar‐H2O mixture were investigated. Furthermore, the effect of argon addition and reactor temperature on the hydrogen production from water vapor plasmolysis was performed. It was found that the hydrogen concentration was enhanced with the argon gas flow rate and plasma voltage increase. Moreover, the H2 concentration results of the water vapor simulation model selecting the dissociative attachment reaction (H−) were nearly the same as that obtained from the experimental results. Also, it was observed that the energy efficiency was enhanced with the plasma input power increased. Moreover, the comparison showed that the hydrogen concentration of argon gas addition was lower than that obtained from water vapor plasmolysis at PTR heating temperature of 90°C.

The Role of Synthetic Fuels for a Carbon Neutral Economy

Fossil fuels depletion and increasing environmental impacts arising from their use call for seeking growing supplies from renewable and nuclear primary energy sources. However, it is necessary to simultaneously attend to both the electrical power needs and the specificities of the transport and industrial sector requirements. A major question posed by the shift away from traditional fossil fuels towards renewable energy sources lies in matching the power demand with the daily and seasonal oscillation and the intermittency of these natural energy fluxes. Huge energy storage requirements become necessary or otherwise the decline of the power factor of both the renewable and conventional generation would mean loss of resources. On the other hand, liquid and gaseous fuels, for which there is vast storage and distribution capacity available, appear essential to supply the transport sector for a very long time ahead, besides their domestic and industrial roles. Within this context, the present assessment suggests that proven technologies and sound tested principles are available to develop an integrated energy system, relying on synthetic fuels. These would incorporate carbon capture and utilization in a closed carbon cycle, progressively relying mostly on solar and/or nuclear primary sources, providing both electric power and gaseous/liquid hydrocarbon fuels, having ample storage capacity, and able to timely satisfy all forms of energy demand. The principles and means are already available to develop a carbon-neutral synthetic fuel economy.

“…Consider first a kinetic model of hydrogen production by plasmolysis of water vapour in an atmospheric pressure, dielectric barrier discharge (DBD), micro-channel reactor (Rehman et al 2012). The starting reactants comprise an amount of water vapour slightly above boiling point and electrons at varying energy levels between 3 − 5eV and densities, typical of non-thermal plasmas.…”

Pulsed power applied to electrolysis offers a potential method for efficient hydrogen production which has not been comprehensively studied to date. Pulsed and plasma electrolysis are introduced and previous research assessed. Electrolysis use in potential space or aerospace applications is substantially weight and volume sensitive. Pulsed plasma electrolysis is able to far exceed the Faradaic limit on electrolysis at very high surface current densities presenting the opportunity to reduce electrode mass and volume. Pulse generation technology is introduced and challenges inherent in application to electrolysis outlined.
