Understanding Hydrogen:
Hydrogen is produced through several methods, the most common being steam methane reforming, partial oxidation of hydrocarbons, and electrolysis of water.
Steam methane reforming involves reacting natural gas with high-temperature steam to produce hydrogen along with carbon monoxide and a small amount of carbon dioxide. This method accounts for the majority of hydrogen produced in the United States.
Partial oxidation of hydrocarbons uses high temperatures without combustion to produce hydrogen from natural gas or other light hydrocarbons. This method emits less carbon dioxide but is less efficient than steam reforming.
Electrolysis uses electricity to split water into hydrogen and oxygen. This method offers the possibility of emission-free hydrogen production if renewable energy sources are used.

Industrial Applications of Hydrogen:
Hydrogen has a wide range of industrial applications across multiple sectors including manufacturing, chemical processing, automotive, aerospace, and more. This versatility stems from hydrogen's unique chemical properties that make it useful as a fuel, a feedstock, an energy carrier, and a reducing agent.
Some of the major industrial uses of hydrogen are:
Manufacturing & Metal Fabrication:
Hydrogen plays a key role in many manufacturing and metal fabrication processes. One of the most common uses is in welding and cutting stainless steel. The gas is often mixed with argon in a 75/25 hydrogen/argon ratio. This gas mixture provides a hotter flame compared to pure argon, allowing for faster welding speeds. The hydrogen also helps remove oxides and impurities from the metal during welding. This prevents oxidation and produces smooth, high-quality welds.
Stainless steel fabricators?rely on hydrogen/argon mixes for automated and robotic welding applications. The fast welding speeds enabled by hydrogen help improve manufacturing efficiency. Hydrogen is also utilized for plasma arc cutting of stainless steel. It produces precise cuts while minimizing slag and oxidation. The high-pressure hydrogen supplied by Westair is ideal for feeding these welding and cutting processes consistently.?
With proper precautions, compressed hydrogen can be safely handled and plumbed into production environments. Westair partners with metal fabricators to ensure a steady supply of hydrogen tailored to their specific needs.
Chemical Processing:
Hydrogen plays a crucial role in multiple chemical processing applications. One major use is in oil refining, where hydrogen is used to convert heavy hydrocarbons into lighter and more valuable products like gasoline and diesel. The process, called hydrocracking, uses a catalyst along with high temperature and pressure to crack large hydrocarbon molecules into smaller ones in the presence of hydrogen.
Hydrogen is also essential in the production of common industrial acids like sulfuric acid (H2SO4) and hydrochloric acid (HCl). Sulfuric acid, one of the most widely used chemicals worldwide, is produced by the contact process which involves reacting sulfur dioxide (SO2) with oxygen in the presence of a vanadium catalyst to form sulfur trioxide (SO3). The sulfur trioxide then reacts with water to produce sulfuric acid. Hydrogen plays a key role in the intermediate steps, ensuring high purity and yield of the end product.
Similarly, in the production of hydrochloric acid, hydrogen is reacted with chlorine gas to generate the Hydrogen chloride (HCl) gas which is then dissolved in water to produce hydrochloric acid. Precise control of the hydrogen flow allows manufacturers to produce hydrochloric acid at the desired concentrations.
Overall, hydrogen enables more efficient and higher purity production of these two vitally important industrial acids. Chemical companies rely heavily on a consistent supply of high-quality hydrogen to meet their processing needs.
Automotive:
Hydrogen is an ideal alternative energy source for the automotive industry due to its potential for lower emissions compared to fossil fuels. When used in fuel cells, the chemical energy of hydrogen is converted into electrical energy to power electric motors in vehicles. This electrochemical reaction between hydrogen and oxygen produces only water and heat as byproducts, eliminating harmful tailpipe emissions of greenhouse gases and air pollutants.
Automakers have invested significantly in developing and commercializing hydrogen fuel cell vehicles, with models already on the market from Toyota, Honda, and Hyundai. As fuel cell technology continues advancing, hydrogen is poised to play an integral role in sustainable transportation by reducing dependence on gasoline and diesel. With higher energy density by weight than batteries, hydrogen provides an extended vehicle range comparable to conventional cars, while only emitting water vapor.
The growth of hydrogen fueling infrastructure will be critical to support the more widespread adoption of fuel-cell electric vehicles. Companies like Westair can assist by providing a reliable supply of hydrogen to fueling stations across regions. Overall, hydrogen enables the automotive industry to work towards a future of clean, efficient vehicles with zero harmful emissions.

Aerospace & Defense:
Hydrogen plays an integral role in the aerospace and defense industries. Its unique properties make it ideal for use in rocket propulsion as well as manufacturing jet engines and gas turbines.
When it comes to rocket propulsion, hydrogen is one of the most common and powerful rocket fuels. When combusted with liquid oxygen, the resulting water vapor provides substantial thrust to propel rockets into space. Hydrogen fuel has been used in the upper stages of space launch vehicles dating back to the 1950s. Today, hydrogen remains an essential propellant for rockets carrying payloads into orbit and beyond. Compared to hydrocarbon fuels, hydrogen provides superior performance, resulting in more payload capacity per launch.
Hydrogen also has applications in manufacturing turbines and jet engines within the aerospace industry. The turbines used in jet engines operate at extremely high temperatures. Hydrogen is used to manufacture those turbine blades in a process called powder bed fusion. This 3D printing method uses lasers to selectively melt metal powder layer by layer to build complex geometries. Hydrogen maintains an inert atmosphere during the build process, resulting in smooth surfaces and material properties better suited for high-temperature engine applications.
Overall, hydrogen enables advanced propulsion systems and manufacturing techniques that are critical to the aerospace and defense sectors. Its unique combustion and manufacturing properties make hydrogen an irreplaceable resource for powering rockets and fabricating advanced turbine components.
Primary Materials:
Glass manufacturing is one of the most crucial applications for hydrogen gas. The production of glass requires extremely high temperatures, frequently over 1500°C. Hydrogen plays a vital role as a reducing agent in this process.
When natural gas or other fossil fuel-derived compounds are used in glass production, impurities can be introduced. This results in glass that is tinted or lacks clarity and brilliance. Hydrogen, on the other hand, provides a clean, colorless fuel that enables the production of high-quality glass with exceptional purity and transparency.
By bubbling hydrogen through the molten glass mixture, it removes oxygen bubbles that would otherwise cause imperfections. The hydrogen reacts with the oxygen to form water vapor that escapes the molten glass. This is critical for manufacturing optical glass used in precision lenses, windows, and displays.
In addition, the combustion of pure hydrogen as a fuel source produces water vapor as the only byproduct. This is a significant advantage over other hydrocarbon fuels that generate carbon dioxide and other greenhouse gases. The use of hydrogen minimizes the environmental impact of glass production.
With its unique properties as a reducing agent and clean-burning fuel, hydrogen has become indispensable for glass manufacturers seeking to optimize quality and efficiency. Westair provides a steady supply of pressurized hydrogen gas to meet the needs of glass production facilities across various industries.
Analytical Chemistry:
Hydrogen plays an important role in analytical chemistry as a carrier gas in gas chromatography. Gas chromatography is a common laboratory technique used to separate and analyze compounds in a mixture. It relies on a flow of inert gas called carrier gas to transport the sample through a column coated with a stationary phase.
Hydrogen is one of the most commonly used carrier gases because of its low molecular weight and lack of reactivity. When used as the mobile phase in gas chromatography, hydrogen provides efficient separations and narrow, symmetric peaks. This allows for better resolution and sensitivity in detecting sample components.
The benefits of using hydrogen carrier gas include:
