“We can equip all types of electrolysers almost completely – from water treatment to the actual electrolysis and hydrogen quality

measurement at the outlet.” Jens Hundrieser, Regional Industry Manager

Key element for the industry of tomorrow Endress+Hauser is already focusing on the use of green hydrogen, for example for the production of e-ammonia or e-methanol, where it serves as a central raw material for the production of fertilizers and chemicals. In the steel industry, too, hydrogen is increasingly replacing coke in the blast furnace process, thereby avoiding CO₂ emissions. In refineries, it is used to remove sulfur from petroleum products and produce low-sulfur fuels. The combination of pioneering technology, comprehensive expertise and a focus on sustainability makes Endress+Hauser an indispensable partner in the transfor mation towards a climate-neutral industry. With a view to the increasing importance of hydrogen as a key element for the industry of tomorrow, the company is positioning itself as a driving force for a green, emission-free future.

distances. These compounds act like a sponge that absorbs hydrogen through chemical reactions and releases it again when required. The advantage of LOHC systems is that they can transport hydrogen safely and efficiently without requiring any special adaptation of the existing infra structure, such as tankers or pipelines. This makes them a practical and flexible solution for distributing hydrogen over long distances. However, there is one major challenge: High temperatures are generated during both the absorp tion (hydrogenation) and release (dehydrogenation) of hydrogen from LOHC. In order to control these processes safely and efficiently, several measuring points are required to monitor key parameters such as flow rate, level and temperature. Endress+Hauser offers a wide range of products, services and solutions, including Coriolis, thermal and vortex flowmeters, which help to optimize hydrogen based processes. Precise level gages also ensure reliable monitoring of the storage tanks. Sustainable hydrogen storage One particular advantage of hydrogen is its ability to make surplus renewable energy available in the long term: Surpluses from wind and solar energy can be stored in the form of hydrogen and converted back into electricity by reverse electrolysis when required. This makes hydrogen a promising building block for climate protection and the sustainable use of renewable energies. Another advantage is the versatile use of hydrogen in existing infrastructures. In gas turbines, it can be used either as a pure fuel or in blends with natural gas to gener ate clean energy. This option not only offers efficient inte gration of renewable energies but also makes a significant contribution to reducing CO₂ emissions. An outstanding example of this is the Long Ridge Energy (LRE) power plant in the USA, which is the first in the world to demonstrate the usability of admixed hydrogen in power plant operation. Thanks to process solutions from Endress+Hauser, it will be demonstrated that fire risks can be effectively controlled using reliable measurement technology. Salt caverns are a particularly safe solution with a high storage capacity for the long-term storage of hydrogen. These natural, stable cavities, which are created by flushing out salt domes, are ideal for storing large quantities of hydrogen. This means that surplus green hydrogen from renewable energy sources can be temporarily stored during periods of high production and retrieved when needed, for example for power generation or industrial use. Endress+Hauser also plays a key role in this area by developing a wide range of high-precision measurement technologies to make these storage processes efficient and safe.
