About Phaedrus

The project aims at developing HRS infrastructure with a modular dispensing capacity in the range of 50-200 kg per day. If higher capacities are needed, several modules can be combined. Higher capacities, e.g. 1,000 kg/day, would theoretically improve the OPEX as the CAPEX cost in relation to the capacity would be lower. However the project targets the early HRS network roll-out from 2015 onwards to 2020. During this period number of FCEV’s will be low and most likely not enough to support larger HRS’s. Also the reduced CAPEX investments on smaller HRS’s will enable building of more HRS’s in the introduction regions for the same investments as one large HRS.

The concept system will be based upon:

  1. An electrolyser producing high pressure hydrogen (up to 20 MPa) that is compact, efficient and capable of a production volume 200 kg/day;
  2. An electrochemical hydrogen compression system consisting of parallel units for reliable, safe and efficient compression up to 100 MPa at a peak production of 10 to 50 kg/hr. depending on system configuration;
  3. Storage tanks at low (10-20 MPa), or medium (50 MPa) and high pressure (100 MPa);
  4. A dispensing system equipped with a pre-cooling unit, with a capacity of 5 kg/3 min.

The concept system will enable a small footprint, low CAPEX and OPEX refuelling system, complying with the relevant standards: SAE J2601 and SAE J2799.
