Production Storage and Transport Usage

 

For many years, hydrogen technologies have been an integral part of the process industry, especially in areas such as refineries, methanol, and ammonia production, where natural gas and coal primarily serve as the base materials for hydrogen production. With the increasing focus on a low-carbon future, the generation of hydrogen from renewable sources, for example through electrolysis using electricity from solar and wind energy, is gaining importance. This “green” hydrogen production is crucial for the desired decarbonization of the global economy and promises to play a key role in the energy supply of the future.

Throughout the hydrogen value chain – from generation through processing and distribution to storage – the equipment and materials used must meet extreme requirements. They are exposed to temperatures up to -253 °C, pressures up to 700 bar and beyond, as well as specific challenges such as hydrogen migration, which can cause material fatigue and cracking in metals. In addition, handling hydrogen requires special safety measures and materials that can withstand diffusion and the reactive properties of hydrogen. Therefore, the development and implementation of technologies for the safe and efficient handling of hydrogen are crucial for the successful integration of hydrogen as an energy carrier in a wide range of industrial applications.

 

  • Hydrogen-induced embrittlement – Continuous exposure to hydrogen can lead to the phenomenon of hydrogen-induced embrittlement in certain materials. In this process, hydrogen penetrates the microstructure of materials, causing a reduction in mechanical strength and ultimately structural failure. To prevent such negative effects, the selection of materials that come into direct contact with hydrogen is of crucial importance. Typically, the use of austenitic steels such as 316L or 316Ti is recommended. In addition, specialized alloys such as Hastelloy C276, Inconel 718, or 2.4711 (Elgiloy®) offer high resistance against hydrogen embrittlement. Beyond material selection, it is important to follow specific guidelines and best practices in the design and maintenance of hydrogen applications to ensure the integrity and longevity of the components used.
  • Hydrogen permeation – Hydrogen, the lightest element in the periodic table, consists of the second smallest atoms after helium. When in contact with metal surfaces, hydrogen molecules require only a small amount of energy to be split into individual atoms and eventually converted into protons (H+-ions). These protons can then penetrate metal and alloy structures, leading over time to changes in the signal of the measuring sensor. The degree of this effect increases with the energy introduced into the process by higher temperatures or pressures. To minimize the penetration of hydrogen through metal and thus a change in sensor signal, a gold coating provides an effective solution. Gold forms an efficient barrier against hydrogen permeation, with a significantly lower permeation rate compared to common industrial materials such as stainless steel 316L. This protective layer helps ensure the long-term stability and accuracy of sensors in hydrogen-rich environments by significantly reducing the interaction between hydrogen ions and the interior of the sensor. Thus, the reliability and lifespan of measuring instruments in demanding applications, especially at high temperatures and pressures, can be significantly improved.
  • Leaks in hydrogen systems – Hydrogen can form explosive mixtures with air at concentrations as low as 4 mole percent in the air. Therefore, it is critical to avoid or greatly limit leaks in systems that work with hydrogen. An effective ventilation system is essential for the safe operation of hydrogen applications to minimize potential risks. For this reason, metallic seals are often chosen in hydrogen environments, as they offer higher tightness and resistance to the specific properties of hydrogen. Moreover, it is important that the leak rate within the measuring components is kept as low as possible to further increase safety and effectively prevent the unintended release of hydrogen. Modern measuring devices and systems are therefore designed to meet the specific requirements of hydrogen applications, including the use of materials and technologies that minimize leakage rates.
  • Challenges in hydrogen storage – Storing hydrogen poses various challenges in measurement and handling depending on its state of aggregation. In gaseous form, hydrogen is stored at pressures up to 700 bar, requiring the use of pressure sensors that allow measurements up to 1,050 bar to accommodate temperature fluctuations and safety requirements. This is particularly important for use at hydrogen refueling stations. In its liquid form, hydrogen is kept at extremely low temperatures of -253 °C or below. Therefore, solutions for temperature monitoring must not only be capable of precisely measuring these extreme conditions but also not impair the effectiveness of tank insulation. Additionally, the materials and technologies used must be able to withstand harsh environmental conditions without losing accuracy or reliability. It is crucial that the measuring instruments are robust enough to ensure long-term stability and functionality under these extreme conditions, which is a key prerequisite for the safe and efficient use of hydrogen as an energy source.

 

➜ Hydrogen Production

 

Electrolysis

The production of green hydrogen, a key component of the energy transition, typically starts with the process of water electrolysis. In this technology, water molecules (H2O) are split into hydrogen (H2) and oxygen (O2) by the use of electricity derived from renewable sources such as solar energy, wind power, or hydropower.

Currently, three main types of electrolysis processes dominate the market:

  • Alkaline electrolyzers use an aqueous solution of potassium hydroxide as the electrolyte to catalyze the splitting of water molecules.
  • Proton exchange membrane electrolyzers (PEM) use a special polymer electrolyte membrane that allows for high efficiency in hydrogen production.
  • “Solid Oxide Electrolyser Cell” technology (SOEC) relies on the electrochemical decomposition of steam into its components at high temperatures of up to 850 °C.

Each of these electrolysis techniques poses specific operational requirements, especially in terms of process pressure, temperature, and the medium used. To master these challenges, we offer a comprehensive range of measurement solutions for pressure, temperature, flow, and level. These instruments are crucial for the efficient and safe operation of the electrolyzers and thus contribute to the optimization of hydrogen production. In addition, they support the maintenance and monitoring of the facilities to ensure their longevity and reliability, which in turn contributes to cost efficiency and strengthens the green hydrogen economy.

Conventional H2 Production

The vast majority of hydrogen produced worldwide is still obtained through traditional, so-called “gray” technologies. These include processes such as:

  • Steam Methane Reforming (SMR),
  • Autothermal Reforming (ATR), and
  • Partial Oxidation (POX) or gasification processes.

These processes, which occur at high temperatures of at least 750 °C and pressures above 40 bar, challenge the process equipment and measurement technology, as they are very energy-intensive.

In an effort to reduce their CO2 footprint and achieve so-called “blue” hydrogen production, facilities integrate additional process stages for CO2 capture and storage (CCS) as well as for CO2 utilization (CCU). These measures can bind CO2 for later use, preventing direct emissions into the atmosphere and thus contributing to a more environmentally friendly production.

To support these developments, robust and precise measurement technologies are required that can withstand the extreme conditions of hydrogen production while enabling efficient and safe monitoring of the processes. Advances in measurement technology, especially in pressure and temperature measurement as well as in gas analytics, play a crucial role in optimizing these processes and contribute to the realization of a more sustainable hydrogen economy.

➜ Hydrogen Storage and Transport

 

Storage and Transport

If hydrogen is not produced directly at the point of use, its storage and distribution require special processes. Transport can be carried out via pipeline networks or, more commonly, in transport containers of various sizes and types. The pressure levels for storage vary significantly, from about 20 bar in liquid hydrogen tanks to extremely high pressures of 700 to 1,000 bar in high-pressure gas containers. In particular, liquefied hydrogen (LH2), stored at a temperature of -253 °C, is gaining importance due to its high energy density. This extremely low temperature leads to additional technical requirements and challenges.

Depending on whether the hydrogen is transported in gaseous form or as a cryogenic liquid, adapted measuring technologies are required. For gaseous hydrogen, robust pressure measuring devices are needed that can reliably monitor the high pressures. For handling cryogenic hydrogen, on the other hand, special cryogenic measuring instruments are required that can withstand both the extremely low temperatures and the pressure conditions. These measuring solutions must work precisely and reliably to ensure safe handling during transport and storage, taking into account the specific physical properties of hydrogen.

Compression

Compression technologies are central to the efficiency of hydrogen infrastructure and utilization. Compressors are indispensable for hydrogen vehicle refueling stations as they compress the gas to the necessary high-pressure levels to ensure optimal energy density in the vehicle tanks. Membrane compressors, in particular, are used because they prevent contamination of the hydrogen with oil, which is essential for the fuel’s purity.

In addition to pure compression, precise monitoring and control of operating parameters are crucial for the safety and efficiency of the process. Temperature, pressure, and level measurements are critical at various points in the compressor. Continuous measurement methods and switching systems are also used to ensure smooth and safe operation.

Monitoring the pressure progression not only allows for optimization of the compressor’s performance but also for early detection of maintenance needs and minimization of downtime. In addition, temperature monitoring systems protect against overheating, while level sensors provide continuous monitoring of the medium to enable efficient and safe compression. The integration of advanced sensors and intelligent monitoring technologies thus increases the efficiency, safety, and reliability in the operation of hydrogen compressors.

Hydrogen Fuel Stations

Hydrogen fuel stations are essential for the promotion of hydrogen mobility. They enable the refueling of vehicles with hydrogen as a fuel and typically consist of various components:

  • A hydrogen supply that includes a low-pressure storage, usually up to 250 bar. The stored hydrogen can be in either gaseous or liquid state.
  • A compression area, where the hydrogen is compressed into medium and high-pressure storage up to 900 bar, to achieve the required density for vehicle fuel supply.
  • A cooling unit is required, as the hydrogen must be cooled to temperatures of about -40 °C before it can be safely filled into the vehicle tank, to ensure optimal density and maximize the efficiency of the refueling process.
  • A dispensing pump, specifically designed for the high-pressure refueling process of hydrogen, enabling fast and safe refueling.

During the refueling process, careful monitoring of temperature and pressure at various points of the system is essential to ensure safety and efficiency. Furthermore, all components and processes must meet the strict requirements of explosion protection to minimize risks in handling the highly flammable hydrogen gas. Therefore, the implementation of reliable monitoring systems and safety measures is crucial to create and maintain a safe infrastructure for hydrogen mobility.

➜ Use of Hydrogen

 

Stationary Fuel Cells

The use of complex stationary fuel cell systems for a variety of applications is steadily growing. These systems are increasingly serving as emergency power supplies, as an alternative to conventional diesel generators, and are being used in the energy supply of public facilities and private homes. Particularly interesting are these systems in combination with renewable energy sources such as solar and wind power, which serve as local suppliers of green energy. The excess hydrogen produced can be compressed and stored for later use, ensuring an efficient and sustainable energy supply.

Similar to electrolyzers that split water into hydrogen and oxygen, not all sensors and measuring devices in these systems come into direct contact with hydrogen. It is essential to also carefully monitor and regulate supporting systems such as water circuits or air circulation to guarantee the optimal performance and safety of the fuel cells. This monitoring involves measuring temperature, pressure, and flow in various parts of the system to ensure efficient and trouble-free operation and to ensure the longevity of the components.

Mobile Fuel Cells

On the path to a more environmentally friendly mobility with reduced CO2 emissions, hydrogen is increasingly seen as a promising alternative, especially in the field of commercial vehicles. This includes trucks, buses, vehicles for municipal services, forklifts, and trains. The refueling of these vehicles typically occurs at a pressure of 350 bar, with a trend towards a standard of 700 bar, which is already being used in passenger cars. This development reflects the efforts to achieve a higher energy density in the tank in order to extend the range of the vehicles and shorten refueling times, which is crucial for wider acceptance and use of hydrogen as fuel.
