The Netherlands – Neste is entering into execution phase with its partners in the MultiPLHY consortium. The MultiPLHY project aims at installing, integrating and operating the world’s first high-temperature electrolyzer system in multi-megawatt-scale (~2.4 MW) at Nesteā€™s renewable products refinery in Rotterdam to demonstrate production of green hydrogen for the refinery’s processes.

The MultiPLHY project started in early 2020 and since then the conceptual design has been completed while detailed engineering is being finalized. In the next phase, Neste will proceed with the construction works. In addition to Neste and Sunfire, the MultiPLHY consortium partners include CEA, a French public research organization; Paul Wurth, an engineering company and technology provider; ENGIE, a global reference in low-carbon energy and services.

ā€˜As part of Nesteā€™s growth strategy we continue to focus on innovation, in which renewable hydrogen and Power-to-X are two of our key development areas. Demonstrating green hydrogen production at our Rotterdam refinery within the MultiPLHY project is one of the initiatives enabling us to further drive the development of new sustainable technologiesā€™, says Lars Peter Lindfors, Senior Vice President of Innovation at Neste.

High-temperature electrolyzer

Demonstrating the high-temperature electrolyzer technology is an important step forward in the field of Power-to-X. In the scope of the project, electrolysis company Sunfire will supply the multi-megawatt electrolyzer based on the innovative SOEC (solid oxide electrolysis cell) technology, operating at high temperatures of 850 Ā°C. Due to the utilization of heat, the high-temperature electrolyzer requires significantly less electricity to produce one kilogram of green hydrogen.
