Abstract This study quantifies the levelized cost of hydrogen (LCOH) and life cycle carbon emissions (LCCE) four production systems via water electrolysis in 31 provinces regions China through optimization method, compares with coal, natural gas, industry by-products. The results show that grid-connected system electrolysis, which has low-carbon advantages only specific provinces, time-of-use electricity prices can improve its economic competitiveness. off-grid achieve near-zero emissions, although significant investment is brought by configuring larger capacities for energy storage tank. In 2045–2050, it will become most economical pathway to produce hydrogen, certain reduction incentives or subsidy may enable this happen 5–15 years earlier. Before then, by-products a good alternative development energy.

This publication explores current and prospective methods for hydrogen production purification, with a strong emphasis on membrane-based technologies purification separation. focus is justified by the ongoing shift towards renewable energy sources (RESs) in electricity generation, necessitating strategic changes to increase utilization, particularly automotive, heavy road, rail sectors, 2025–2030. The adoption of from RESs construction, energy, industrial sectors (e.g., process heat or fertilizer production) also under consideration, driving need innovative production, separation, methods. Historically, industrial-scale has been predominantly derived fossil fuels, but such as electrolysis, biological, thermal processes now offer alternatives varying efficiencies (0.06–80%) gas compositions. Therefore, selecting appropriate separation critical based specific usage requirements composition. Industrial-scale commonly employs pressure swing adsorption (PSA) technologies, capable achieving up 99.99% purity. Cryogenic distillation suitable applications needing 95% Membrane including polymer, metallic, electrolytic membranes, have traditionally limited moderate volumes pure are crucial critically evaluates potential membrane technology response anticipated rise demand RES-derived hydrogen, feedstocks.

There are various ways to reduce emissions harmful the environment, including carbon dioxide gas produced from different industries that depend on fossil fuels, which is considered a non-renewable energy sources will end one day. Recently, there has been strong focus finding alternative and renewable produce energy. One of these use hydrogen as resource for many applications, most important electricity generation. This study deals with mechanism production through electrolysis water, was represented by model cell, factors affecting amount such time, concentration, electrolyte type. Two catalysts (electrolyte type) were employed in this study, namely sodium hydroxide NaOH potassium KOH, they used order evaluate levels production. Experimental results showed catalyst better than hydroxide, due activity ion medium, plays an role dissolution process The best (140 ml) at 3 minutes, 4 amperes, 10 volts, concentration 5 g/L KOH. Faradaic efficiency both mediums. experimental highest Faraday 0.179% g/L.
