Hydrogen is obtained from a variety of sources. It almost always needs one or more stages of purification before further processing. Pressure swing adsorption (PSA), for example, is a demanding process in which Linde is deemed an expert the world over, offering systems with capacities up to 400,000 Nm³/h and purities of over 99.999 vol. %.
To store hydrogen with the highest possible density and therefore the greatest efficiency, it must be cooled and liquefied. The liquid hydrogen is stored in an insulated tank for further distribution. Capacities of Linde Kryotechnik hydrogen liquefiers range from 150 l/h to more than 20,000 l/h.
Linde has more than forty years’ experience in building hydrogen liquefaction plants.
Linde through Linde Kryotechnik is the world’s leading manufacturer of cryogenic equipment with expertise in the planning, design and construction of hydrogen liquefiers as well as refrigerators.
