TransHyDE-Project Safe Infrastructure

Coordinated by RMA Rheinau – Project Duration 04/2021 – 03/2025 – Funding Code 03HY202A

Safely into the future with hydrogen transport and distribution grids

Can our existing natural gas grids and underground storage facilities be used for hydrogen in future? 11 research and industry partners in the TransHyDE-project Safe Infrastructure approach this question since April 2021. It is like a puzzle: many pieces are necessary and linked, but finally detailed analysis is required to provide valid answers.

By participating in the TransHyDE-project Safe Infrastructure, RMA is making a significant contibution to the energy transition. Developing hydrogen-compatible products for a trans-European hydrogen network is the key to success. This will ensure safe pipeline transport and distribution of hydrogen to end-users. In addition, accurate determination of hydrogen purity and quantity is essential to advance the hydrogen economy. At RMA, we are committed to doing our part.

The key project areas are

  • Developing guidelines and regulations for materials and underground storage units
  • Identifying hydrogen leaks early and safely
  • Measuring gas impurities reliably
  • Determine gas volumes accurately
  • Demonstrate in a field test the conversion of a natural gas to a hydrogen distribution grid


June 2023

RMA put the H2-Loop into operation. It is the first hydrogen test bench for the calibration of hydrogen gas meters world-wide.

September 2023

Germany’s first feed-in unit goes live. It was built by Thüga, Energie Südbayern and Energienetze Bayern. RMA delivered hydrogen-compatible compoments like rotary piston meters, house connections and service entrance boxes.
