<h3>Hydrogen Production Technologies Overview</h3>

Hydrogen Production Technologies Overview

main source of hydrogen production is based on the fossil fuels. It can be pre-sented as a commercial mature technology which it can be applied at low costs and get high efficiencies [90]. The hydrogen production especially using the steam reforming process of methane can get the efficiency range of (65% - 75%).

<h3>Membrane-Based Electrolysis for Hydrogen Production: A Review</h3>

Membrane-Based Electrolysis for Hydrogen Production: A Review

Gray hydrogen refers to the hydrogen synthesized via the steam methane reforming (SMR) method, as well as the residual hydrogen from chemical processes in chlor-alkali plants. Blue hydrogen refers to a gray hydrogen that has undergone a postproduction step called carbon capture and utilization (CCU) process [ 25 , 35 , 36 ].

<h3>Production of hydrogen - U.S. Energy Information </h3>

Jan 21, 2022 · Steam-methane reforming currently accounts for nearly all commercially produced hydrogen in the United States. Commercial hydrogen producers and petroleum refineries use steam-methane reforming to separate hydrogen atoms from carbon atoms in methane (CH 4 ). In steam-methane reforming, high-temperature steam (1,300°F to 1,800°F) under 3–25 bar pressure (1 bar = 14.5 pounds per square inch) reacts with methane in the presence of a catalyst to produce hydrogen, carbon monoxide, and a

Steam-Methane Reforming. Most hydrogen produced today in the United States is made via steam-methane reforming, a mature production process in which high-temperature steam (700°C–1,000°C) is used to produce hydrogen from a methane source, such as natural gas. In steam-methane reforming, methane reacts with steam under 3–25 bar pressure (1 bar = 14.5 psi) in the presence of a catalyst to produce hydrogen, carbon monoxide, and a relatively small amount of carbon dioxide.
