    Energy from Hydrogen

    Climate neutrality, sustainability and the reduction of CO2 emissions are now global trends. The decarbonization of the energy sector plays an important role in this context, as this sector contributes significantly to CO2 emissions. A promising strategy here is the use of renewable gases such as biogas or sustainably produced hydrogen gas, or that of admixtures of renewable gases with natural gas. Thanks to its versatility, hydrogen is a particularly promising candidate for supporting decarbonization efforts, with great potential for the future.

    Using hydrogen for energy storage and distribution requires some adaption of the existing gas infrastructure and close monitoring for safety and performance reasons. The required flexibility in the gas composition poses a major challenge to the industry if the infrastructure is to run optimally and efficiently. Sensirion’s sensor technology can handle this broad requirement and is thus an ideal solution for your future products.

    Choose Sensirion as your technology provider to ensure you are ready for an H2 future. Thanks to our broad sensor portfolio and technology know-how, we are your ideal partner for handling the complex developments in technology and regulations.


    Applications

    Gas Metering

    The microthermal measurement principle of the sensors ensures billing-grade consumption monitoring for 0 – 100% hydrogen content in natural gas. This allows for the most compact gas meters.

    Fuel Cells

    Higher energy efficiency and system longevity can both be achieved by fine-tuning the air/gas ratio through Sensirion flow sensors.

    Hydrogen Leak Detection

    To ensure safety and to comply with local regulations, the infrastructure and appliances must be monitored for leaks. Sensirion technology offers leak detection at relevant gas concentrations at minimal power, enabling battery-driven applications and remote monitoring. Thanks to the technology’s robust construction and long-term stability, operators no longer have to worry about leaks going undetected.

    Combustion Control for Appliances

    Our sensor technology offers the highest energy class for boilers and burners, regardless of the composition, by using an adaptive combustion control mechanism and measuring the gas/H2 blend.

    Energy Measurement

    As the gas composition in the grid becomes increasingly variable, industrial applications more than ever require information on the energy content of the gas they are operating on. Sensirion’s flow technology can provide information about the properties of the gas relevant to these applications, and can cope with biogas as well as H2 blends.

    Gas Analysis and Calibration Instruments

    The long-term reliability, high precision and durability of Sensirion’s products enable efficient instrument control and process optimization. Sensirion’s sensors have been used for the last 20 years to control hydrogen and technical gases in demanding applications such as gas chromatography and calibration/verification equipment.


    Specialist Article: The Microthermal Measurement Principle

    The Ideal Choice for Future-Proof Gas Meters Operating with Natural Gas/Hydrogen Mixtures

    Using hydrogen admixtures in particular is a novel practice, and its compatibility with the current gas infrastructure is not yet fully understood, nor has it been investigated in depth. Gas meters are an essential part of the gas infrastructure and are indispensable in reliably and fairly billing gas consumption for all gas customers.

    In this article, we will examine the metrological behavior of the microthermal measurement principle for gas meters operating with natural gas mixtures containing significant amounts of hydrogen. We will present measurement data, discuss measurement accuracy and operational safety, and explain why the compact size of microthermal gas meters can be maintained regardless of the hydrogen admixtures, which is a key advantage compared to other meter technologies.
