Hydrogen Gas Flow Measurement: Rising Up to the Challenge

Over the past 5 decades, the demand for hydrogen has tripled, mostly due to refining and industrial uses. Hydrogen shows promise to decarbonize a range of sectors with recent technology advancements and policy initiatives. As such, instrumentation and control engineers in the process industries are being challenged more frequently for reliable and cost-effective measurement solutions. This workshop will provide both engineers and operators with an understanding of thermal flow technology and the benefits that allow for more accurate mass flow measurement of hydrogen and other gases.

Increasing demand for hydrogen is spurring the development of lower cost, energy efficient, and carbon-neutral production. While green hydrogen is the most desirable of the color spectrum, costs to produce hydrogen from renewable resources are higher than using natural gas.  Blue and grey hydrogen production remain the most common sources at this time.

Within the process Industries, a good portion of the hydrogen used in refineries, ammonia plants, methanol plants and steel mills is derived from fossil fuels. There is also a push to blend hydrogen with natural gas to increase the calorific value as a fuel source in the generation of electricity. These are industries in which accurate, reliable, and safe measurements are required.

Most applications do not require custody-transfer level accuracy, and the high total cost of ownership associated with that type of instrumentation. Flow meter technologies such as thermal can provide these measurements without breaking the bank with regard to initial purchase, installation, and maintenance costs. At the end of the workshop, engineers and operators will have a better understanding of thermal flow technology, where the technology is commonly used and pitfalls to avoid when it comes to instrument selection and application.

Key Takeaways

  • Review the growing hydrogen market and some of the impact it is having in the process industries.
