IMI supplies 4 MW electrolyser to API SARPOM refinery

IMI is supplying a 4 MW PEM electrolyser to the SARPOM Refinery in Trecate, Novara, Italy, operated by IP Gruppo API. The renewable hydrogen produced will replace a portion of the non-renewable hydrogen currently used in refining processes.

The investment forms part of API’s Green Hydrogen Production Plant project. Funded by the Piedmont Region through the Piano Nazionale di Ripresa e Resilienza (National Recovery and Resilience Plan), this initiative aims to produce green hydrogen using energy generated by two photovoltaic fields located within the refinery. These fields will deliver an estimated annual production of more than 8,500 MWh of renewable energy.

Hydrogen will be produced by a 4 MW PEM electrolyser designed and built by IMI, which will be installed in a decommissioned area of the refinery previously used for hydrocarbon storage. This area will be revitalised, aligning with regional funding guidelines. The estimated annual production is at least 167 metric tons of renewable hydrogen.

Factory testing was completed in December 2024, and the final assembly of the electrolyser is already underway, with delivery and commissioning planned for the first half of 2025.

Giuseppe Buscemi, EMEA President of Process Automation at IMI, said: “This project showcases the power and versatility of our PEM electrolysers. We are pushing decarbonisation forward within heavy industry, and our work with API sets a great precedent as one of Italy’s first 4 MW PEM hydrogen electrolysers.”
