The economic analysis for hydrogen production cost towards electrolyzer technologies: Current and future competitiveness

Bowen Yang et al.

Summary: Hydrogen production through electrolysis technology has sparked extensive research in the field of clean energy acquisition. Mainstream electrolyzers, such as alkaline electrolyzer (ALK), anion exchange membrane electrolyzer (AEM), and proton exchange membrane electrolyzer (PEM), are compared in terms of their current and future hydrogen production costs. The characteristics of these technologies are described in terms of polarization curve parameters, as well as crucial materials like catalysts and membranes. A bottom-up hydrogen production cost prediction model is established, considering technical factors, manufacturing, and operating considerations. The model predicts that ALK will have a 23.85% and 51.59% lower hydrogen production cost compared to AEM and PEM technologies in the short term. However, with technological advancements, AEM and PEM are expected to have a 24% and 56.5% lower cost in the medium-term and long-term, respectively. The lifespan of electrolyzers greatly affects the cost of hydrogen production. Additionally, the cost reduction potential resulting from various technical factors is explored for future planning of the hydrogen economy.

Bifunctional oxovanadate doped cobalt carbonate for high-efficient overall water splitting in alkaline-anion-exchange-membrane water-electrolyzer

Abhishek Meena et al.

Summary: The self-supported oxovanadate-doped cobalt carbonate (VCoCOx@NF) on nickel foam (NF) is a high-performance catalyst for overall water splitting in alkaline-anionexchange-membrane-water-electrolyzer (AAEMWE). It shows excellent activity for both hydrogen and oxygen evolution reactions, reducing overpotentials and achieving overall water splitting at low cell voltages. The doping of V species enhances the HER and OER at the Co site, providing potential for large-scale hydrogen production utilizing V- and Co-based bimetallic oxide materials.

Effects of operation and shutdown parameters and electrode materials on the reverse current phenomenon in alkaline water analyzers

Ashraf Abdel Haleem et al.

Summary: This study experimentally and theoretically investigated the reverse current phenomenon that occurs after shutdown in alkaline water electrolyzers coupled with intermittent renewable energy sources. It was found that the potential of the electrodes on either side of the bipolar plate changes according to the amount of reverse charge flowing through the plate during shutdown. The study also uncovered the effects of operating parameters and electrode materials on the reverse current phenomenon. The findings have implications for adapting alkaline water electrolyzers to dynamic operation.

Design considerations for industrial water electrolyzer plants

Md Rizwan et al.

Summary: This work proposes a shared balance of plant and power supply design for industrial scale alkaline electrolyzer plant to reduce CAPEX and minimize OPEX losses during variable load operation. The study shows that the design of individual balance of plant per stack is optimal for high capacity operation, while shared balance and power supply can increase hydrogen production by 8-12% when operated with variable lye flowrate. Cooling duty in the lye circulation loop should be based on the cooling requirements of degraded electrolyzer stacks at the end of life.
