Over 190 H 2 fueling stations around the world are already equipped with our technology. Linde Hydrogen FuelTech provides high-performance refueling concepts and technologies and is thus paving the way for end-to-end hydrogen infrastructures. Hydrogen is the key to a more environmentally friendly mobility ecosystem.
Another transportation option for hydrogen is to deliver it to the point of use in converted form, i.e. A cavern of this type is already operated by Linde on a commercial basis in Texas. Hydrogen-filled cavities can act as a backup for a pipeline network. The gas has to be purified and compressed before it can be injected into the cavern. For bulk storage of gaseous hydrogen, underground salt caverns are an option.
This guarantees extended storage windows combined with maximum safety.
We also offer our customers transportable LH 2 containers with active cooling. Different capacities are available, ranging from 3,000 liters to over 100,000 liters. The liquid hydrogen (LH 2) is efficiently stored in vacuum-insulated tanks which can be installed either vertically or horizontally. Cryogenic tanks can be provided to store the hydrogen if it is not going to be used directly. Several production facilities can feed H 2 into the network and it, in turn, can supply the gas to multiple customers at different locations. We supply this equipment as part of integrated offerings for our customers’ hydrogen projects.Ī pipeline network is probably the best option if multiple customers on an industrial site require hydrogen. In addition, we offer turbocompressors for hydrogen and LH 2 pumps. This process increases the density of the gas. They cool the volatile gas down to minus 253 degrees Celsius to create liquefied hydrogen (LH 2). Cryogenic plants are used to liquefy hydrogen so it can be transported and stored efficiently. These products may be called green ammonia or green methanol if green hydrogen is utilized as a feedstock. Linde can also offer synthesis plants for the production of ammonia (NH 3) or methanol (CH 3OH) converting the produced hydrogen and nitrogen, respectively syngas stream. Where needed, the captured CO 2 can be used for enhanced oil recovery (EOR) or fed into a purification or liquefaction plant to enable further use cases. The use of low-energy coil-wound heat exchangers makes this a particularly economical gas purification method. RECTISOL ® wash is a physical acid gas process for segregated removing sulfur and CO 2 from the synthesis gas at subzero temperatures. CO 2 can also be recovered from the flue gas of hydrogen plants by Post Combustion Capture (PCC). The PSA system can also be used to remove or recover carbon dioxide from process gas streams at synthesis gas plants. We have also developed an alternative hybrid process where we combine membrane and pressure swing adsorption (PSA) technologies for new-found levels of flexibility and efficiency in the production of H 2. Pressure swing adsorption plants are used to obtain H 2 from hydrogen-rich synthesis gases or refinery and petrochemical gases. We offer cryogenic processes (condensation or methane scrubbing) to separate these two gases post CO 2 removal. Steam reforming initially produces synthesis gas – a mixture of hydrogen and carbon monoxide and carbon dioxide. ITM Linde Electrolysis (ILE) joint venture, we are one of the world’s leading suppliers of PEM electrolyzer technologies (proton-exchange membranes), which means that our customers can rely on us for end-to-end, integrated green H 2 solutions. The electricity needed for this electrolysis process is generated exclusively from renewable sources. Green hydrogen (H 2) is obtained either by steam reforming, if bio-based feedstock is available, or by splitting water by electrolysis. If the carbon dioxide (CO 2) contained in this gas is removed in a downstream carbon capture process, the resulting hydrogen is called blue. This residue material is heated to a very high temperature with oxygen and steam to produce a raw synthesis gas. Gray hydrogen can also be produced through the Since fossil fuels are used in this production method, the end product is called gray hydrogen. This mixture of carbon monoxide and hydrogen is then further processed. In an initial step, feedstocks such as natural gas, LPG or naphtha are combined with steam to produce synthesis gas with the aid of a heterogeneous catalyst. Steam reforming is the main method used to produce hydrogen on an industrial scale today.
