MultiPHLY: first multi-megawatt high-temperature electrolysis unit

By ENGIE - 23 November 2021 - 10:00

Intended to cover the needs of the NESTE biorefinery in Rotterdam, the MultiPLHY project will allow renewable hydrogen production to replace "grey" hydrogen.


A unique demonstrator... 

Having completed the design and detailed engineering stages, the MultiPLHY consortium partners - ENGIE, Neste, Sunfire, CEA and Paul Wurth - are now entering the execution phase and are preparing to start construction for commissioning in 2022. Based on the innovative SOEC (solid oxide electrolysis cell) technology, the high-temperature electrolyser operating at 850°C represents a world first in terms of production on a megawatt scale.


... Decarbonising the refining industry

The technology implemented at the Neste facility in Rotterdam will allow limited use of electrical energy to produce green hydrogen and will reduce the refinery's carbon footprint by approximately 8,000 tonnes by 2024. 
The MultiPLHY project has been supported by the European Union's Horizon 2020 research and innovation programme, Hydrogen Europe and Hydrogen Europe research, and demonstrates the ability of green hydrogen to decarbonise the refining industry.
