MULTIPLHY to demo first large-scale high-temperature electrolyzer system
In the Netherlands, a consortium with CEA, Neste, Paul Wurth Group, ENGIE, and Sunfire have announced a project-partnership to build and operate the world’s first multi-megawatt scale high-temperature electrolyzer for highly efficient hydrogen production. The MULTIPLHY project – “Multi-megawatt high-temperature electrolyzer to generate green hydrogen for the production of high-quality biofuels” has recently been launched at Neste’s renewable products refinery in Rotterdam.
Led by the French Alternative Energies and Atomic Energy Commission (Le Commissariat à l’énergie atomique et aux énergies alternatives – CEA), a public research organization, as project coordinator, the project involves renewable products specialist Neste, plant builder Paul Wurth Group, the energy utility ENGIE and the cleantech company Sunfire GmbH.
The consortium will install, integrate and operate the world’s first high-temperature electrolyzer (HTE) system in multi-megawatt-scale at Neste’s Rotterdam facility.
Neste is a global forerunner in renewable fuels with the ambition to become a global leader in renewable and circular solutions. Demonstrating green hydrogen production at our Rotterdam refinery enables us to drive the development of new sustainable technologies aiming at decreasing the carbon footprint of our customers, said Lars Peter Lindfors, SVP Innovation, Neste.
MULTIPLHY marks the first demonstration of an HTE in an industrial refining process with a nominal power input of 2.6 MW and a hydrogen production capacity of 60 kg/h reaching an electrical efficiency of up to 85 percent AC to LHV H2.
ENGIE is delighted to be part of MULTIPLHY to decarbonize Neste’s biorefinery. This is the world’s first multi-megawatt high-temperature electrolysis project to produce hydrogen. We will contribute our expertise and increase our knowledge to extend ENGIE’s renewable hydrogen-based solutions, and enable our customers’ zero-carbon journey, said Michèle Azalbert, CEO of ENGIE’s Hydrogen Business Unit.
By the end of 2024, the electrolyzer is expected to have been in operation for 16,000 hours or more, producing a total of around 960 tonnes of green hydrogen while avoiding approximately 8,000 tonnes of GHG emissions.
The project supports the most promising Carbon Direct Avoidance (CDA) approach by substituting “grey” hydrogen currently generated via steam-methane reforming (SMR) by certified green hydrogen.
Our involvement in the MULTIPLHY project is an important part of our strategy for the transformation of the industry towards Zero Carbon Emissions, especially as H2 is considered THE reducing agent of the future in the world of ironmaking, remarked Georges Rassel, CEO of Paul Wurth.
The project has received EUR 6.9 million in funding from the Fuel Cells and Hydrogen 2 Joint Undertaking (FCH2-JU) under grant agreement No 875123. The JU receives support from the EU’s Horizon 2020 research and innovation programme and France, Germany, Finland, Luxembourg.
