SIAD Macchine Impianti (SIAD MI) has produced a hydrogen compressor for a large-scale, multi-megawatt, high-temperature electrolyzer. The contract was requested by Paul Wurth, an engineering company in Luxembourg. 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 Macchine Impianti 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 outstanding continuity of operation.

Once delivered, the hydrogen compressor will be an integral part of the renewable products refinery of NESTE. A green attitude shared by SIAD Macchine Impianti, which from this viewpoint, designs and builds tailor-made plants carefully constructed around the requirements of the customer. Because of this, SIAD MI is renowned on the market as a reliable partner for the supply of zero impact and high efficiency solutions.

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