High Pressure Hydrogen All Electrochemical Decentralized RefUeling Station
To develop and validate a new concept for 700 Bar hydrogen retail refuelling stations by showing the applicability of electrochemical hydrogen compression technology in combination with a PEM electrolyser, storage units and a dispensing system.
Achievements to date
After 2.5 months, the basic functionality of all system components has been proven. The work on modelling and system design has started.
Phaedrus will deliver a new 700 bar retail refuelling technology which is characterized by low CAPEX/OPEX cost, standardized interfaces, high accuracy and compliancy with SAE J2601, SAE J2799 and ISO 20100
Within the project, a new concept and new technologies for a hydrogen retail refuelling systems are developed. The higher outlet pressure available from the electrolyser as well as improved efficiency and compression ratio ability of the electrochemical compressor will result in an optimization of compression and storage systems with respect to cost, efficiency and capacity.
The station concept is flexible and scalable and is therefore perfectly suited for early vehicle deployment volumes and subsequent growth. Also, the cooling and refuelling subsystems are optimised as part of an overall system optimisation.
For the system optimisation, well-to wheel studies including thermodynamic balances are applied using simulation methods for technical/economic analyses, assessments and layouts for components and control and energy management. The simulation will serve in addition to the assessment of the potential of electrochemical compressors by studying a broader spectrum of system configurations, conducting benchmark studies and considering future R&D advancements.
The project is scheduled to last 3 years and can be regarded as phase one of a two-step development. In the first phase, technology will be developed and validated on a 5 kg/day scale. A complete Hydrogen Refuelling System design is made for 200 kg/day capacity. Subsequently, in phase two, the technology will be demonstrated in a scalable 200 kg/day Hydrogen Refuelling System.
