In January, the first of four years of the EU project ALRIGH2T will conclude, with the Technical University of Munich (TUM) represented by the Institute of Plant and Process Technology (APT). The project aims to develop and demonstrate two technologies for refueling aircraft with liquid hydrogen at airports in Milan and Paris. These technologies include direct refueling of an aircraft with liquid hydrogen and a tank-swapping system, where an empty tank is replaced with a filled one.
As part of ALRIGH2T, APT is collaborating with Linde plc to develop and model a direct refueling system based on a newly designed liquid hydrogen centrifugal pump. Within Work Package 3, such a pump will be developed and tested in a pilot facility. Additionally, a dynamic model for the filling and discharge processes of liquid hydrogen using the centrifugal pump is being developed to optimize the overall system.
APT is responsible for creating the direct refueling model. Over the past year, the focus has been on developing a dynamic model for liquid hydrogen pipelines and a model describing the filled tank system. These models will be further refined and validated with facility data in the coming year. Progress will also continue on the development and testing of the centrifugal pump.
