Polymer electrolyte membrane water electrolyzers (PEMWE) are currently restricted to an operating temperature range between 50 to 80 °C. This review shows that elevated temperature (ET) above 90 °C can be advantageous with respect to i) reduced cell voltages, ii) a reduction of catalyst loading or possibly the employment of less noble electrocatalysts, and iii) a greater potential for waste heat utilization when the electrolyzer is operated in exothermal mode (when the cell voltage is higher than the thermoneutral voltage). Together with presenting an overview of the materials and components utilized in elevated temperature PEMWE under liquid and steam operation, this article summarizes the experimental and modeling performances reported to date, highlights the challenges ahead, and suggests aspects, which will need to be considered to improve the performance at elevated temperature. Key points, which arise from this work are the extensive need of re‐assessing the material selection both for the cell components and also at a system level, the effects and optimization of working with steam operation, and in the long run, the need for techno‐economic analyses to ultimately assess whether efficiency gains will truly translate to a cost‐effective technology alternative.

This study presents the first work that investigates a preliminary design generating hydrogen from the wastewater of coal utility boilers via an integrated photovoltaic (PV)−electrolysis system. Connecting solar panels, which generates electricity, to an electrolyzer to split water molecules to hydrogen and oxygen is an attractive method to generate hydrogen. A numerical model is developed for the integrated PV solar panels and polymer electrolyte membrane (PEM) electrolyzer. Parallel solar panels and series PEM electrolyzer cells are considered in the present work to reach the optimum arrangement. The essential losses including the activation and ohmic overpotentials and the required energy for rotary equipment (compressors and pumps) are considered in the model. The effect of the working temperature, solar irradiation, and charge transfer coefficient on the efficiency of the system is investigated. The calculated efficiency of the PEM electrolyzer and PV solar panels is in the range of 60−62.5% and 18−20%, respectively. The efficiency of the integrated PV electrolyzer increases as solar irradiation increases. Of particular interest is the potential application of the present design in Texas, which generates 1.43 × 10 4 Nm 3 /year of green hydrogen for $4.67/kg H 2 by only scaling up by 11. This model provides valuable insights for the large-scale hydrogen generation from power plants' wastewater via the coupled solar energy and electrolysis system.

Different hydrogen production scenarios need to be compared in regard to multiple, and often distinct aspects. It is well known that hydrogen production technologies based on environmentally-friendly renewable energy sources have higher values of the economic indicators than methods based on fossil fuels. Therefore, how should this decision criterion (environmental) prevail over the other types of decision criteria (technical and economic) to make a scenario where hydrogen production only uses renewable energy sources the most attractive option for a decision-maker? This article presents the results of a multi-variant comparative analysis of scenarios to annually produce one million tons of pure hydrogen (99.999%) via electrolysis in Poland. The compared variants were found to differ in terms of electricity sources feeding the electrolyzers. The research demonstrated that the scenario where hydrogen production uses energy from photovoltaics only becomes the best option for the environmental criterion weighting value at 61%. Taking the aging effect of photovoltaic installation (PV) panels and electrolyzers after 10 years of operation into account, the limit value of the environmental criterion rises to 63%. The carried out analyses may serve as the basis for the creation of systems supporting the development of clean and green hydrogen production technologies.
