Leakage management system for pipeline monitoring
Hydrogen is critical to the energy transition as it is a clean, versatile fuel that can significantly reduce greenhouse gas emissions when produced with renewable energy. It serves as an important energy carrier that can store and transport energy from intermittent renewable sources such as solar and wind power.
The hydrogen value chain includes production, storage, distribution, and utilisation. Green hydrogen is mainly produced through electrolysis. The green hydrogen is stored as compressed gas, liquid hydrogen, or in chemical forms such as amoninia. Distribution methods include pipelines, trucks, rail, and shipping. Utilisation spans industrial processes, transportation (fuel cell vehicles), power generation (stationary and portable fuel cells), and residential/commercial heating and power.
Challenges
Process measurement technology that comes into contact with hydrogen must fulfil special requirements. As hydrogen is a small molecule that easily diffuses through materials, the devices must be particularly leak-proof and made of hydrogen-resistant materials to prevent leaks and embrittlement. Austenitic stainless steels or special plastics are often used. They must also be corrosion-resistant, especially in the presence of moist hydrogen.
As hydrogen is highly flammable, the devices must comply with explosion protection requirements (e.g. ATEX, IECEx). They must be able to withstand extreme pressures (up to 1000 bar) and temperatures without losing their function. The measuring devices must remain precise and stable and be calibrated in accordance with international standards. Safety precautions such as emergency shutdowns must be quickly taken to prevent additional risk for example in the event of leaks.
How can KROHNE provide support?
In hydrogen processing, advanced measurement solutions are critical for ensuring both safety and efficiency.

The ALTOSONIC V12 flowmeter, equipped with customised transducer technology, provides a robust and reliable option, offers a robust and reliable option that is resistant to hydrogen embrittlement even at elevated temperatures, making it ideal for hydrogen applications.
However, hydrogen presents unique challenges, such as the diffusion of atomic hydrogen through standard diaphragm seals on pressure transmitters, which can cause gas accumulation and degradation of the system. To address this, KROHNE has developed pressure transmitters with gold-plated diaphragms and ceramic measuring cells, significantly enhancing durability and performance in hydrogen environments.
Customised measurement solutions
KROHNE’s metering systems are deployed throughout the entire hydrogen value chain, from production and pipeline transport to industrial use and storage. Since hydrogen may contain impurities like H2O, O2, CO2, CO, or CH4 depending on its production method, KROHNE metering solutions also analyses the composition of the gas.
Leakage management system for pipeline monitoring
As hydrogen plays an increasingly pivotal role in the energy transition, safe and cost-effective transportation, particularly through pipelines, is vital. Given hydrogen's propensity for leaks and the risk of embrittlement, robust leak detection systems are essential for maintaining the integrity and safety of hydrogen infrastructure.
