abstract

The present paper describes a model of wind energy conversion system (WECS) for hydrogen production by water electrolysis in the region of Hassi R'mel (South of Algeria), developed under Simulink environment, The amounts of hydrogen produced using a WECS were considered as a case study for the three different sites of Hassi R'mel, Telghemt, and Delaa located in the region of Hassi R'mel. The results showed that Telghemt and Hassi Delaa sites have significant wind potential with average wind speeds exceeding 9 m/s at 25 m height. The dominant hydrogen production is occurred for the site of Telghemt, approximately 49286 Nm3 during favorable month (April).

Conclusion

This study relates to hydrogen production from wind energy, it is important to mention that this work was conducted as part of work for estimating the hydrogen production from wind source in the region of Hassi R'mel. However, it can be considered as preliminary results to estimate the amount of hydrogen that can be generated from wind energy in this region. For this purpose, a model of wind energy conversion system for hydrogen production through electrolysis in the region of Hassi R'mel has been developed under Simulink environment. In order to estimate the amount of hydrogen produced, the full electric energy produced from wind energy is converted into hydrogen by electrolysis methods. An overview of the potentiality of hydrogen production from wind power in the region of Hassi R'mel (Algeria) has been given; an example of simulation was applied to three sites (Hassi R'mel, Telghemt, and Hassi Delaa) where the meteorological data are available. It can be noted that hydrogen production depends on the wind speed, its frequency distribution and the size of the wind turbine. The results showed that the hydrogen production using a wind energy conversion system with 330 kW rated power is reaching the range of 261362 Nm3 /year at 25 m above ground level. In order to improve the system efficiency, it is recommended to choose a suitable system for the exploitation of the energy available and a well windy site. To evaluate the hydrogen production from wind energy systems, it is important to make an accurate wind energy resource assessment. The predicted annual hydrogen flow rates are strongly affected by the climatic conditions of wind speed.
