High-temperature Electrolyzer to Demonstrate the Production of Renewable Hydrogen Started up at Neste’s Rotterdam Refinery
The pioneering MultiPLHY project demonstrating renewable hydrogen production has reached a key milestone: The consortium partners have successfully started up the world’s largest multi-megawatt high-temperature electrolyzer (HTE) in an industrial environment at Neste’s renewable products refinery in Rotterdam, the Netherlands. The pilot project demonstrates the viability of renewable hydrogen in reducing the use of fossil hydrogen in the refining industry. Replacing hydrogen produced from fossil raw materials with renewable hydrogen is one of the key means to lower greenhouse gas emissions in refining. As a next step in the demonstration project, a test program will validate the technology’s performance characteristics.
MultiPLHY is a demonstration project with consortium partners Neste, Sunfire, CEA, and ENGIE. The high-temperature electrolyzer is provided by the German electrolyzer manufacturer Sunfire and the hydrogen processing unit (HPU) by SMS group. Neste is responsible for the refinery integration and together with Sunfire oversees the operation of the unit. The research and technology organization CEA coordinates the project, and ENGIE is in charge of techno-economic assessment.
The electrolyzer integrated into Neste’s refinery processes is based on SOEC (Solid Oxide Electrolysis Cell) technology by Sunfire. The high-temperature electrolyzer (2,6 MW) consists of twelve electrolysis modules, operating at high temperatures of 850 °C to produce more than 60 kg/h of renewable hydrogen. Due to the utilization of heat, the high-temperature electrolyzer requires significantly less electricity to produce renewable hydrogen compared to other solutions on the market.
This project has received funding from the Fuel Cells and Hydrogen 2 Joint Undertaking (now Clean Hydrogen Partnership) under grant agreement No 875123. This Joint Undertaking receives support from the European Union’s Horizon 2020 research and innovation programme, Hydrogen Europe and Hydrogen Europe research.
