A comprehensive review of alkaline water electrolysis mathematical modeling

CO2 electrolysis system (CES), as a type of carbon capture, utilization, and storage, has significant potential for achieving carbon neutrality. By utilizing surplus renewable energy, CES can convert CO2 into valuable electrochemical products. This paper studies the advantages brought by the application of CES to the green economic operation of multi‐energy system. Firstly, a linear model based on the CES's operation data is developed to characterize its dynamic behaviour. In addition, a two‐stage stochastic programming model for the operation of CES within multi‐energy system is studied. Finally, a creative optimal‐operation‐based end‐of‐life net present value (OENPV) is proposed to assess the long‐term investment of CES. The results of the cases in different seasons and electrochemical products show that the application of CES not only brings significant carbon reduction to the multi‐energy system, but also alleviates the curtailment of renewable energy. Additionally, according to the OENPV analysis outcome, the production of formic acid gives the system the shortest return on investment, which is the fourth year of the 20‐year assessment cycle.

Photoelectrochemical (PEC) hydrogen production is an emerging technology that uses renewable solar light aimed to establish a sustainable carbon‐neutral society. The barriers to commercialization are low efficiency and high cost. To date, researchers have focused on materials and systems. However, recent studies have been conducted to utilize thermal effects in PEC hydrogen production. This Review provides a fresh perspective to utilize the thermal effects for PEC performance enhancement while delineating the underlying principles and equations associated with efficiency. The fundamentals of the thermal effect on the PEC system are summarized from various perspectives: kinetics, thermodynamics, and empirical equations. Based on this, materials are classified as plasmonic metals, quantum dot‐based semiconductors, and photothermal organic materials, which have an inherent response to photothermal irradiation. Finally, the economic viability and challenges of these strategies for PEC are explained, which can pave the way for the future progress in the field.

“…1,2 Currently, the main commercially available technologies for GH are alkaline water electrolysis (AWE) and polymer electrolyte membrane (PEM) electrolysis, but the former has enormous advantages in terms of scale-up because inexpensive 3d transition metal elements can be used as catalysts. 3,4 However, its energy conversion efficiency is strongly restricted by the anode reaction of the oxygen evolution reaction (OER), which is a sluggish process involving four proton-coupled electrontransfer steps. 5,6 In the last few decades, the materials used for driving the OER under alkaline conditions have made great progress; specically, nickel-iron (oxy)hydroxides (NiFeO x H y ) were considered the most promising catalysts because of their excellent acceleration of OER dynamics and strong stability.…”
