NASDAQ: LIN

Process gases, including hydrogen, helium, carbon dioxide, carbon monoxide, specialty gases and acetylene are produced by other production methods.

Hydrogen is produced from several different feedstocks using a range of technologies. Today, carbon intensity is used to designate and differentiate between the production processes and the respective feedstocks used to produce the molecule. The majority of conventional hydrogen currently produced by Linde is derived from natural gas or methane, using steam methane reformation (SMR) or auto-thermal reforming (ATR) technology. Linde has a range of technologies to produce low-carbon hydrogen from fossil feedstocks, or renewable hydrogen from renewable energy (non-fossil feedstock). Both products are considered sources of clean energy. Low-carbon (blue) hydrogen is produced primarily from methane, by capturing carbon emissions from a hydrogen production plant and sequestering them subsurface for the long term. Renewable (green) hydrogen is produced by electrolysis using renewable energy and water as feedstock. Other sources of low-carbon hydrogen are existing chemical and petrochemical processes, out of which Linde recovers hydrogen for subsequent treatment and cleaning to achieve ultra-high purity levels.

Carbon monoxide can be produced by either SMR or ATR of natural gas or other feedstock such as naphtha, a by-product in the petrochemical industry. Most carbon dioxide comes as an industrial by-product, that is sourced from chemical plants, refineries and other processes or is recovered from natural carbon dioxide sources. Raw carbon dioxide is processed and purified in Linde’s plants to produce commercial and food-grade carbon dioxide. Helium is sourced from certain helium-rich natural gas streams in the United States, with additional supplies being acquired from outside the United States. Acetylene is primarily sourced as a chemical by-product, but may also be produced from calcium carbide and water.

Industrial Gases Distribution

There are three basic distribution methods for industrial gases: (i) on-site or tonnage; (ii) merchant or bulk liquid; and (iii) packaged or cylinder gases. These distribution methods are often integrated, with products from all three supply modes coming from the same plant. The method of supply is generally determined by the lowest cost means of meeting the customer’s needs, depending upon factors such as volume requirements, purity, pattern of usage, and the form in which the product is used (as a gas or as a cryogenic liquid).

On-site. Customers that require the largest volumes of product (typically oxygen, nitrogen and hydrogen) and that have a relatively constant demand pattern are supplied by cryogenic and process gas on-site plants. Linde constructs plants on or adjacent to these customers’ sites and supplies the product directly to customers by pipeline. On-site product supply contracts generally are total requirement contracts with terms typically ranging from 10-20 years and containing minimum purchase requirements and price escalation provisions. Many of the cryogenic on-site plants also produce liquid products for the merchant market. Therefore, plants are typically not dedicated to a single customer. Air separation technologies also allow on-site delivery to customers with smaller volume requirements.

Merchant. The merchant business is generally associated with distributable liquid oxygen, nitrogen, argon, hydrogen, helium and carbon dioxide. The deliveries generally are made from Linde’s plants by tanker trucks to storage containers at the customer's site which are usually owned and maintained by Linde and leased to the customer. Due to distribution cost, merchant oxygen and nitrogen generally have a relatively small distribution radius from the plants at which they are produced. Merchant argon, hydrogen and helium can be shipped much longer distances. The customer agreements used in the merchant business are usually three to seven-year requirement contracts.

Packaged Gases. Customers requiring small volumes are supplied products in metal containers called cylinders, under medium to high pressure. Packaged gases include atmospheric gases, hydrogen, helium, carbon dioxide, acetylene and related products. Linde also produces and distributes in cylinders a wide range of specialty gases and mixtures. Cylinders may be delivered to the customer’s site or picked up by the customer at a packaging facility or retail store. Packaged gases are generally sold under one to three-year supply contracts and through purchase orders.

Engineering

Linde’s Engineering business has a global presence, with its focus on market segments such as air separation, hydrogen, synthesis, olefin and natural gas plants. The company utilizes its process engineering expertise in the planning, design and construction of efficient plants for the production and processing of gases. Engineering uses sustainable technologies to help customers avoid, capture and utilize carbon dioxide emissions. Its technology portfolio covers the entire value chain for production, liquefaction, storage, distribution and application of hydrogen which supports the transition to clean energy. Its digital services and solutions increase plant efficiency and performance.

Linde's plants are used in a wide variety of fields: in the petrochemical and chemical industries, in refineries and fertilizer plants, to recover air gases, to produce synthesis gases, to treat natural gas and to produce noble gases. The Engineering business either supplies plant components directly to the customer or to the industrial gas business of Linde which operates the plants under long-term gases supply contracts.

Inventories – Linde carries inventories of merchant and cylinder gases and hardgoods to supply products to its customers on a reasonable delivery schedule. On-site plants and pipeline complexes have limited inventory. Inventory obsolescence is not material to Linde’s business.

Customers – Linde is not dependent upon a single customer or a few customers.

International – Linde is a global enterprise with approximately 64% of its 2025 sales outside of the United States. The company also has majority or wholly owned subsidiaries that operate in approximately 50 European, Middle Eastern and African countries (including Germany, the United Kingdom (U.K.), France, Sweden, and the Republic of South Africa); approximately 15 Asian and South Pacific countries (including China, Australia, India and South Korea); and approximately 20 countries in North and South America (including the U.S., Canada, Mexico and Brazil).

The company also has equity method investments operating in Asia, Europe, and the Middle East.

Linde’s non-U.S. business is subject to risks customarily encountered in non-U.S. operations, including fluctuations in foreign currency exchange rates, import and export controls, and other economic, political and regulatory policies of local governments. Also, see
