Emerson introduces the TESCOM Anderson Greenwood Instrumentation H2 valve series for hydrogen applications up to 15,000 pounds per square inch (psi) (103.4 megapascals (MPa)). The new solution reliably isolates process pressures in high-pressure gas applications such as hydrogen refueling stations and tube trailers, reducing fugitive emissions and improving safety.
When hydrogen is transferred from the tank to the pump, it delivers pressures up to 15,000 psi (103.4 MPa). To protect personnel and prevent leaks, they must be effectively contained and isolated. The double block and bleed (DBB) valve's positive double block configuration provides two levels of positive shutoff to protect maintenance personnel from high pressure during instrument maintenance. The valve's modular design reduces the number of potential leak points, and enhanced sealing technology reduces the risk of fuel entering the environment through the valve stem.
Among the clean fuels produced from renewable sources, compressed hydrogen is used to power fuel cell electric vehicles (FCEVs). In 2021, 142 new hydrogen refueling stations were put into operation, the largest single-year increase, bringing the world to 685 hydrogen refueling stations in operation. In January 2022, Global Market Insights Inc. predicted that the FCEV market will exceed $15 billion by 2027. To meet this growing demand, hydrogen station original equipment manufacturers (OEMs) must source reliable, high-performance components to ensure overall equipment efficiency and station safety.
"Given the hydrogen pressures experienced in these applications, we must ensure that equipment can always operate safely and reliably. That's why we are committed to developing components specifically to help our customers efficiently store and accurately control compressed hydrogen." Emerson TESCOM Precision Fluids Rob Lindquist, Director of Global Marketing at Control.manual valves and double block and bleed valves in the H2 valve family support manual operation and feature a maintenance-free design that minimizes maintenance and downtime. With low operating torque and adjustment-free sealing technology, these manual valves reduce the cost of ownership of a compact solution.
For OEMs looking to minimize operator risk in a safe manner, the H2 valve family offers a wealth of safety features. Each valve has an intuitive QR code that allows operators to quickly understand valve specifications during maintenance and installation. The product also ensures that high pressure liquids or gases are not released during maintenance. These valves meet the ISO 19880-3 standard for hydrogenation.with the new 15,000psi (103.4MPa) product line, Emerson offers a comprehensive portfolio of TESCOM solutions for the safe and accurate operation of hydrogen refueling stations.
