SIAD develops hydrogen compressor for high-temperature electrolyzer

SIAD Macchine Impianti (SIAD MI) has produced a hydrogen compressor for a large-scale, multi-megawatt, high-temperature electrolyzer, which is to 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 the delivery of hydrogen of adequate quality to the end user Neste.

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 outstanding continuity of operation.

The MULTIPLHY project aims at installing, integrating, and operating the world’s first high-temperature electrolyzer system on a multi-megawatt-scale (~2.4 MW) at Neste’s renewable products refinery in Rotterdam to demonstrate production of green hydrogen for the refinery’s processes.
