Pre-Normative Research on Gaseous Hydrogen Transfer

2nd Expert Networking Group meeting

Performance and profitability of CGH2 HRS can be improved by reducing pre-cooling requirements.

When filling a hydrogen tank the gas heats up. In reverse, when emptying a tank it cools down. This is especially relevant when fast-filling an FCEV and emptying a hydrogen trailer. Global regulations limit the temperature range for FCEV equipment from –40 to +85°C. Today, this is implemented by limiting the gas temperature and by pre-cooling the hydrogen to -40°C at the HRS. But the most extreme temperatures occur only in the gas, not in the tank wall. This may allow to reduce pre-cooling efforts.
The aim of HyTransfer is to recommend an improved gas transfer procedure for implementation in global regulations, codes and standards (RCS). Reduced pre-cooling requirements enable reduced HRS down-times and equipment costs as well as reduced energy demand.


To discuss several topics as CFD, pre-cooling, SAE requirements.
The goal of the Expert Networking Group is to shed strategic light on H2 mobility, standardization of filling requirements as well as on all the HyTransfer results. External factors and standardization trends must be considered throughout HyTransfer to adjust the research process and the formulation of the final recommendations.
