Interview with Paolo Taddei
- What benefits will be gained from establishing a digital twin for the hydrogen storage system and how it is going to operate for Temperature and Pressure Swing regulation?
This is the digital twin preview:
It must be seen as an instrumnet for the design of the storage system and its optimization. DT will allow to test different ACs and MOF properties in a digital environment with fast response to identify best suitable ultraporous material properties. DT will aslo allow to change the initial conditions of pressure, temperature both of the tank and the hydrogen and the pressure ramp rate to simulate all possible conditions for better filling the tank.
- What strategies are used in the manufacturing of storage demonstrator (supplementary Fig. S5) to ensure maximum capacity of storage and efficient integration/storage of densified adsorbent media?
The tank will be made by WAAM in alluminium 5183, this material and manufacturing process has required a detailed FEM to ensure and verify material stress analysis in all part of the tank, bolts included. Ultraporous materials as ACs and MOF are specifically developed to ensure maximum adsorbtion @77K max 100bar.
- What parameters for the hydrogen storage control system are subject to monitoring at these tests and what ensures their proper performance? How will be assurance of components fatigue resistance achieved in this case?
The lab storage system will be equipped with control and monitoring instrumentation; parameters as temperature, pressure, mass flow will be monitored during filling and emptying processes as they give a measure of the storage capacity and performances.
Fatigue issue will be tested in lab for materials and main components; the lab storage system will not be effected by fatigue because of low rate of filling cycle during MAST3Rboost project.
- What are expected challenges in design the refueling interface and supporting components on or at each hydrogen refueling station, including materials of construction compatibility with storage system?
The envisage storage system will work @77K and max100bar that represents a middle way between pressurized hydrogen storage systems (up to 800bar) and cryogenic storage systems (20K); therefore the interface between the tank and the refueling station will benefit of these conditions.
