Periodic Reporting for period 1 - COSMHYC XL (COmbined hybrid Solution of Metal HYdride and mechanical Compressors for eXtra Large scale hydrogen refuelling stations)
Reporting period: 2019-01-01 to 2020-06-30
Significant achievements were reached during the first phase of the project:
- Economic analysis confirms that the flexible hybrid system proposed by the consortium is well adapted for large applications and allows for a whole range of configurations (e.g. different input pressures depending on the hydrogen supply).
- Metal hydrides with required performance were successfully developed. The impact of different possible pollutants on the metal hydride compressor is being analysed.
- New thermal integration concepts were developed and tested in order to increase the performance of the new metal hydride compressor. Development activities are also on-going on the mechanical compressor to allow its use for both Light Duty Vehicles and Heavy Duty Vehicles applications.
- Modelling and draft designs were performed for the large-scale oriented system integration. The work currently focus is on the effiency optimization thanks to innovative thermodynamic concepts.
The consortium partners are currently focussing on the integration of both technologies, which will be tested in a comprehensive way in the second phase of the project, based on joint test protocols.
Also the performances and flow rates of the mechanical compressor will be significantly improved. COSMHYC has already enabled significant improvements of life-time, efficiency and flow rate, aiming at capacities of 120kg/h thanks to innovative system integration concepts. The ambition is to scale up-capacity while maintaining the same time the lifetime and efficiency levels achieved in previous projects, incl. COSMHYC. The new concept will also enable significant noise reductions..
The joint efforts on two compression technologies and on integrating them in a modular and flexible compression solution will allow flow rates will have a significant positive impact on the future costs of refuelling stations. Thanks to the hydride solution, the electricity consumption of the COSMHYC XL hybrid compressor will lower electricity consumption and to strongly reduce CAPEX: a reduction of 50% is expected compared to the current CAPEX of non-mechanical compressors.
