ORACLE - Outdoor Reliable Application using CLean Energy
The goal of the project is to demonstrate a fuel cell based utility vehicle for indoor and outdoor service operations. This is linked to the clear benefits accociated with the implementation of fuel cells. Customers will experience several benefits: extended operation cycle, improved flexibility, improved fuel economy, compact power module, improvement of working environment, communication of environmental and social values. The solution is a combination of better energy supply, improvement of the suction apparatus and improved power pack. ORACLE will demonstrate the technology and its feasibility based on market studies. Based on these findings a new commercial product development will be initiated by Nilfisk-Advance. The following work packages are included in the project: 1) Top level ''Nilfisk-Advance'' market/application analysis; 2) Focused ''Nilfisk-Egholm'' market analysis; 3) Overall electrical topology concept; 4) Suction equipment optimization; 5) Vehicle power interface; 6) MEA; 7) Power pack design and integration; 8) Fuel cell interface; 9) Power pack test; 10) Attachment equipment integration and development; 11) Suction attachment prototype integration; 12) Reporting and dissemination
The purpose of the Oracle project is to develop a demonstrator (the ORACLE machine) to verify the advantages of fuel cell technology on tool carriers used on outdoor cleaning applications. Environmental advantages must be reached in comparison to existing diesel based solutions, and an improved efficiency must be gained to reduce energy consumption.
Results gained through the project:
- Energy optimization of the fan by using a high efficiency fan, up to 44 %. Partly demon-strated on the Oracle machine.
- Energy optimization of the suction nozzle by using a built-in tank close to street level and ECO-mode, up to 75%. Only the ECO-mode1 demonstrated on the Oracle machine.
- Noise reduced from fan by using the “Bottle Principle”, up to 3 dB (A). Demonstrated on the Oracle machine.
- A mathematical model of the power consumers on the vehicle.
- A model to optimize the efficiency and operational stability of fuel cell modules.
- MEA (Membrane Electrode Assembly) successfully integrated in the SerEnergy stack de-sign. The performance and durability is now comparable with that of the BASF based MEA’s. The cost targets specified in the project and the Danish Roadmap for HTPEM are fulfilled.
- Develop a 5kW Fuel cell module, suitable for at vehicle. Ensuring robustness and price compatible.
- Optimizing robustness for long term durability and start/stop of the system, a part of this is MEA optimization.
- Implementing fuel cell control in embedded controller.
- Developing power electronics for fuel module.
- Demonstrator build and tested.
