Hydrogen (H2)

Clean Hydrogen for today's world

Hydrogen Production

Linde has been harnessing the power of hydrogen for over 100 years and is the global leader in the production, processing, storage, and distribution of hydrogen. Hydrogen is the most abundant element in nature. Even though it is the simplest molecule (consisting of two protons and two electrons held together by electrostatic forces) hydrogen is a powerful energy carrier. Today hydrogen is primarily manufactured industrially by conventional steam methane reformation (SMR) of hydrocarbons or partial oxidation of carbon-based energy sources. With the growth and availability of alternative, low carbon-based energy sources, in combination with low carbon production processes, industrial quantities of hydrogen can be produced with a low carbon intensity.

A Range of Hydrogen Carbon Intensity

Linde hydrogen - grey designationConventional steam methane reforming (SMR) where natural gas is separated into its components is a mature, efficient and reliable production resource. Carbon dioxide is emitted during the production process leading to a carbon footprint for the hydrogen produced. In the industry, hydrogen produced from natural gas or petroleum where the carbon dioxide emissions are not captured is referred to as grey hydrogen.

Linde  hydrogen - blue designationConverting natural gas into hydrogen and carbon dioxide through traditional SMR but in combination with carbon capture or sequestration provides the potential for lowering the CO2 emissions. When the carbon dioxide produced is captured and stored this results in hydrogen with lower carbon intensity and is identified as blue hydrogen.

Linde hydrogen - green designationWhen the energy for liquefaction of hydrogen uses power derived from renewable energy sources like wind turbines, solar panel arrays or hydro-electric facilities in combination with electrolysis, there is no emitted carbon dioxide from the electricity production. Electrolysis splits water into its components producing hydrogen and oxygen. Combined with low-carbon power, electrolysis can be used to produce hydrogen without any carbon emissions. This hydrogen is categorized on the color scale as green.

Energy & Decarbonization Applications

Hydrogen as part of the manufacturing process of tradition fuels helps make them more sustainable by reducing the atmospheric pollutants (SOX) associated with the use of those fuels. In fuel cells, hydrogen is the energy source. The cells are used for powering cars, buses, trucks, rail, ships and planes or stationary power needs via back-up power.

Hydrogen can be used to store energy. This is particularly attractive in supporting the variable nature of energy produced from wind and solar power. Excess renewable energy can be used to produce hydrogen which in turn can be stored in bulk quantities for use later or in different locations. The stored hydrogen can be distributed through various channels to be applied to a broad range of decarbonization applications - from reducing transportation fuel emissions to help lower the carbon footprint traditionally carbon intensive industries.

Hydrogen is used as a raw material for production of ammonia, methanol, hydrogen peroxide, polymers, and solvents. It is used to hydrogenate fats and oils, in the production of vitamins, chemical processes and other pharmaceutical products. Hydrogen is also used as an inert or reducing environment for treating metal, glass manufacturing, and welding.

Uses and Applications of Hydrogen Gas and Liquid Hydrogen by Industry


As a heat treating furnace atmosphere, hydrogen reacts with oxygen to produce a bright finish on steel parts. It also makes an excellent industrial quench gas because of its high heat transfer properties. When used as an alternate fuel, hydrogen plays a key role in reducing undesirable emissions.

Heat Treating
Parts Manufacturing


Our hydrogen is used to propel everything from land speed record-breaking vehicles, to fuel cell powered passenger cars, buses and forklifts.

Hydrogen for Fuel Cells


Hydrogen is essential in today’s refining industry for upgrading heavy crude oils into refined fuels, and helping to meet increasingly tight transportation fuel specifications.

Hydrogen Gas & Liquid Hydrogen (H2) Supply: Tanks, Cylinders, Containers, Pipelines & Plants


For smaller, more specialized applications, we offer hydrogen in high-pressure gas cylinders or liquid containers in a variety of sizes.

Bulk Delivery

If you require medium-range amounts of hydrogen, we offer bulk liquid deliveries that are made by truck and stored in hydrogen tanks located at your site. We also deliver hydrogen in high-pressure gas tube trailers to provide flexibility for supply pressure and flow rate.


The company maintains sophisticated hydrogen pipeline operations for large volume users in several key geographies with significant refining and chemical activity. We control and monitor each of our hydrogen pipelines to assure purity and to ensure that customers get the flow rate they want at the pressure they need.

On-Site Production

As your supply needs grow beyond bulk, We can provide small or large on-site hydrogen supply. We design, install, own, and operate every system, so you don't have to worry about maintenance. On-site plant sizes range from 9,000scfd (10 NCMH) to as as large as 135MMscfd (150,000 NCMH). Our plants, whether small or large can offer reliable supply that meets your exact specifications for purity, pressure and flow.
