Project Title:

Development of a wind hydrogen system (20 kW)

Ref.No.: 33

Project Type and Category:

Hydrogen production

Project Duration:

1987 – 1991

Project Participants:

Herr Professor Sigurd Schulien, Projekt Wasserstofftechnik, FB Physikalische Technik, FH Wiesbaden,
AGAFE (Arbeitsgemeinschaft für angewandte Forschung und Entwicklung von Mitgliedern der FH Wiesbaden e.V.

Sponsor:

Hessen ministery for econony

Project Budget and
Funding:

1,5 Mio DM

Project Description and Objectives:

Since 1988, a small test installation is being opperated by the Fachhochschule Wiesbaden on the mountain Feldberg/ Taunus, Germany, and consists of a 20 kW wind energy converter (at wind velocities of 11 m/s), an alkaline pressurized electrolyzer of 20 kW (at 3 MPa, 50 cells at 125 V and 160 A), a pressurized gas storage in bottles (of 2.4 m3 volume) and of two hydrogen operated gas motor generators (8 kW and 4 kW) with external mixture formation built into one generator unit with individual fuel conditioning equipment for each engine. The overall primary energy efficiency of the system ""wind converter – electrolysis - combustion engine - electric generator"" is approximately 15%.
The wind energy converter is designed for stand alone operation and feeds its pulsating direct current in first place into the electrolyzer. Additionally the electricty is used for heating purposes in the staff shelters of the test installation. Also a battery is fed which provides electricity for the measuring and monitoring equipment in case wind is not available. An electronic power conditioning unit optimizes the electricity supply to the various consumers.

Technical Goals:

Goal of this project is to optimize the system 'wind energy converter/ electricity supply/ pressurized electrolyzer/ storage/ generator', as well as each component itself. The energy production costs calculated over a 10 year depreciation periode are estimated to be 1.6 DM/ kWhe.

Project Status
