To reduce climate change and carbonization of the atmosphere, today it is proposed to switch to green energy and use hydrogen as an energy source. When hydrogen burns, water forms, and carbon oxides are not released. Methods for processing solid, liquid, and gaseous fuels, as well as water electrolysis, are proposed for hydrogen production. The ele...
In this paper, the effect of rotating magnetic fields on hydrogen generation from water electrolysis is analyzed, aiming to provide a research reference for hydrogen production and improving hydrogen production efficiency. The electrolytic environment is formed by alkaline solutions and special electrolytic cells. The two electrolytic cells are con...
Polymer electrolyte membrane (PEM)-based electrochemical methanol reformation has gained interest as a practical way to produce hydrogen than water electrolysis due to its low operating voltages. Development of alternative PEM for this application is of considerable interest in order to reduce the cost as well as increase the system efficiency. Pre...

This is the ReadMe file of a SuperPro Designer example that analyzes the production of green hydrogen via bioconversion pathways and water electrolysis. The bioconversion process utilizes 18 metric tons (MT) per hour of wheat straw as feedstock which is converted into fermentable sugars via thermochemical and enzymatic hydrolysis. Biohydrogen is produced using a combination of sequential dark and photo fermentation and the product is purified using pressure swing adsorption. The process generates 1.1 MT/hour of purified biohydrogen. The electrolytic process utilizes 10 MT/hour of municipal water, which is converted into ultrapure water and then electrolyzed to produce 1.1 MT/hour of purified hydrogen. This example also includes a model for hydrogen liquefaction. The analysis results for all three processes include material and energy balances, equipment sizing, capital, and operating cost estimation. The results indicate that significant government subsidies are necessary for the financial viability of such investments considering the current technologies and market dynamics.
