H-TEC SYSTEMS has chosen AEG PS power package solution for the hydrogen production plant built at Haurup in Schleswig-Holstein by the renewable energy company “Energie des Nordens” (EdN).

The project was implemented to optimize local wind energy production. A lot of excess wind power is generated at this grid node. By implementing the electrolyzer, every kilowatt produced can be used instead of switching off the wind turbines. The newly developed system with a nominal output of one megawatt is to feed up to three million kilowatt hours from excess wind power as hydrogen annually into the gas network. The plant contributes to the supply of around 20,000 proWindgas customers of Greenpeace Energy, main shareholder of EdN. It is also supporting the stabilization of the grid. The renewable gas can be stored in the existing gas network and converted back into electricity in flexible gas-fired power plants anywhere in Germany, if required.

H-TEC SYSTEMS is equipping the plant with an ME 450/1400 PEM electrolyzer. The company supplies the high-tech electrolyzers of the project as a turnkey solution integrated into containers. These compact solutions can be implemented anywhere—directly at wind and solar parks, at filling stations, or in industrial plants.

To supply power to its modular and flexibly deployable electrolyzers H-TEC SYSTEMS chose Thyrobox DC 3 systems also for their flexibility and high efficiency.

The Thyrobox DC 3 was designed to provide good power factor and minimized harmonics even at part loads, which contribute to energy efficiency and limited distortions to the grid feeder, and finally reduce the overall cost of operations of such processes as electrolysis.

"H-TEC SYSTEMS containerized electrolysis process is very innovative and cost efficient," said Andreas Becker, Head of Grid & Storage business at AEG Power Solutions. "Our concept of flexible power supply modules matches closely this approach and we are very proud to be part of  the project at Haurup which is a very good example of how to optimize wind power generation through green hydrogen production."
