Unveiled a year ago, Mid Flow Twin technology is based on an innovative dual-nozzle architecture, enabling significantly reduce hydrogen refueling times while optimizing station installation and operating costs.
This next-generation solution aims to support the rise in hydrogen use, particularly for heavy vehicle fleets, while remaining suitable for light vehicles. It provides a concrete response to the challenges of large-scale deployment of hydrogen infrastructure in Europe.
Innovative Twin nozzle hydrogen refueling technology
Une intégration réussie au sein d’une borne de distribution RHeaDHy
As part of this strategic partnership, HRS has successfully integrated Mid Flow Twin components into a distribution terminal RHeaDHy, developed as part of the European project of the same name. This key milestone demonstrates the technological maturity of the system and marks a decisive step towards its industrialization.
The integrated next-generation components enable a high flow rate of 300 g/s at 700 bar, meeting the rapid refueling requirements of heavy-duty vehicles. The system is now ready to enter a new phase of testing and qualification.
New real-world testing campaign to launch soon
Following the success of this integration phase, HRS will soon launch a new series of qualification tests at its Champagnier test site (Isère). These tests will focus on both the components and their complete integration within the station, in order to continue the development program and prepare for the next stages of standardization.
A concrete response to the requirements of the European AFIR regulation
Thanks to its innovative architecture and high performance, Mid Flow Twin technology enables balancing speed of refueling, flexibility of use, and cost control, thereby directly meeting the objectives of the European AFIR (Alternative Fuels Infrastructure Regulation).
Following the testing phase, work will continue with a view to integrating the technology into international standards, a step expected in summer 2026, which is a prerequisite for the launch of industrial production.
A strategic partnership to accelerate the energy transition
The collaboration between HRS, Toyota Motor Europe and ENGIE Lab CRIGEN illustrates the ability of industry leaders to combine their expertise to develop high-performance, reliable, and economically viable hydrogen refueling solutions. It also confirms HRS's central role in designing modular, scalable, and high-performance hydrogen infrastructure tailored to current and future market needs.
