Summary: This study investigates the diffusion and explosion characteristics of hydrogen after accidental leaks in hydrogen refuelling stations, focusing on the effects of plateau environment on combustible clouds. The results show that the presence of obstacles may lead to the formation of combustible clouds upstream of the leak hole. The low atmospheric pressure in plateau areas results in high hydrogen concentration and large combustible cloud size near the blast wall. The study also highlights the positive effect of the blast wall in preventing the spread of explosion flame.

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.
