SIAD Macchine Impianti (SIAD MI) revealed it has produced a hydrogen compressor for a large-scale, multi-megawatt, high-temperature electrolyzer, contracted by Paul Wurth. The SIAD compressor will be integrated in the hydrogen processing unit, designed and manufactured by Paul Wurth in the frame of the MULTIPLHY project.

Apart from the compressor, the hydrogen processing unit involves a hydrogen dryer as a key element in order to deliver the adequate quality of hydrogen to the end user NESTE, in a reliable way.

The compressor developed by SIAD MI is suitable for automatically managing hydrogen at low pressures (0 to 33 bar). The main feature of the unit developed for the project concerns the oil-free compression of hydrogen, which comes from the electrolysis process mixed with varying percentages of water vapor.

In addition, the device has a compact layout with high accessibility. The selection of premium materials also means that it can offer high performance at very low temperatures (down to -25°C). The compressor is designed to follow the variable operation of the electrolyzer, providing continuity of operation.

Once delivered, the hydrogen compressor will be an integral part of the renewable products refinery of NESTE. 

The MULTIPLHY project has received funding from the Fuel Cells and Hydrogen 2 Joint Undertaking (FCH JU) under the Grant Agreement No 875123. FCH JU receives support from the European Union’s Horizon 2020 research and innovation program, Hydrogen Europe and Hydrogen Europe research.
