“…Alkaline water electrolysis has been standard for many decades in the production of hydrogen for industrial purposes using hydroelectricity, although the commercial availability of PEM electrolysers with input powers exceeding 1 MW is breaking that monopoly. Recent surveys [6][7][8][9] of the available technologies for large scale electricity storage to mitigate problems arising from high wind power penetration into electricity grids have identified large scale alkaline electrolysis as one of the main options for storing wind energy. Compatibility with fuel cells is important for renewable energy systems and filling stations for fuel-cell vehicles, since these involve proton exchange membrane (PEM) fuel cells that may be poisoned by impurity levels above a few parts per million (ppm) in the hydrogen stream.…”

An enhanced one-dimensional model has been developed for an alkaline electrolyser cell for hydrogen production, based on linked modular mathematical models in Simulink ® .Where possible, the model parameters were derived on a physical basis and related to the materials of construction and the configuration of its components. This means that the model can be applied to many alkaline electrolyser cells, whereas existing semi-empirical models were generally developed for a specific cell. In addition to predicting the overall equilibrium electrolyser cell performance, the model is a powerful tool for understanding the contributions to cell voltage from the various internal components. It is thus useful as a guide to researchers aiming for improved performance through modified geometry and enhanced electrode materials. The model performed very well when compared to published models tested against the same sets of experimental data.

“…The reason to minimise the demand of each station is to minimise the final size (hence the capital costs) of each station. The electrolyser characteristics identified in [29] will be used in the optimisation process. The electricity demand of each station will be determined by the optimisation algorithm, and then the demand of each individual electrolyser making up a station will be determined by a local controller at each filling station.…”

“…The novelty of this work is in the strategy and algorithm used to size, place and control electrolysis hydrogen production stations within a distribution network so as to increase wind power capacity and network asset utilisation. The actual characteristics of pressurised alkaline electrolysers, detailed in [29], are used for the first time to design a realistic control strategy to run them in the power system and find their impact on the electric network. The effectiveness of the proposed strategy is investigated through modelling using MATLAB software.…”

Hydrogen could become a significant fuel in the future especially within the transportation sector. Alkaline electrolysers supplied with power from renewable energy sources could be utilised to provide carbon free hydrogen for future hydrogen filling stations supplying Hydrogen Fuel Cell Vehicles (HFCV), or Internal Combustion Engines (ICEs) modified to burn hydrogen. However, there is a need to develop and use appropriate strategies such that the technology delivers greater economic and environmental benefits.

Hydrogen Production from Ethanol Reforming by a Microwave Discharge Using Air as a Working Gas

et al. 2021

Hydrogen production from ethanol reforming using microwave plasmas has great potential. In this study, a microwave plasma torch is used as a plasma source. Air is used as a discharge gas to generate the plasma. Ethanol and air are mixed and injected directly into the plasma reaction zone in a vortex flow. The effects of the oxygen-to-ethanol molar ratio (O 2 /Et), ethanol flow rate, and absorbed microwave power on the reforming results are investigated. When the O 2 /Et exceeds 0.9, ethanol is completely converted. The hydrogen selectivity is the largest when the O 2 /Et is 1.1, which is about 66.5%. The maximum hydrogen production rate is 2.19 mol(H 2 )/mol(C 2 H 5 OH). The best carrier gas residence time is 0.64–0.81 s. An appropriate increase in the ethanol flow rate can improve the ethanol conversion rate and energy efficiency while reducing the hydrogen selectivity and hydrogen yield, so the ethanol flow rate should not exceed 42.1 mL/min. The cost of hydrogen production is minimum [$3.66/kg(H 2 )] when the ethanol flow rate is 42.1 mL/min. The positive effect of the absorbed microwave power on the reforming reaction is significant, but too much microwave power also reduces energy efficiency. The optimum experimental conditions are an O 2 /Et of 0.9, an ethanol flow rate of 42.1 mL/min, and an absorbed microwave power of 700 W. The maximum energy yield is 861.91 NL(H 2 )/kWh at an absorbed microwave power of 700 W. The main reforming products are H 2 , CO, CO 2 , CH 4 , C 2 H 2 , C 2 H 4 , C 2 H 6 , C 3 H 6 , C 3 H 8 , C 4 H 10 n, and C 4 H 10 i. The content of C2 or higher hydrocarbons is considerably low. Almost no deposited carbon is generated in the experiment, which means that the design of the reforming system is effective in suppressing carbon deposition.
