​The shift to a low-carbon EU economy raises the challenge of integrating renewable energy (RES) and cutting the CO2 emissions of energy intensive industries (EII). In this context, hydrogen produced from RES will contribute to decarbonize those industries, as feedstock/fuel/energy storage. MULTIPLHY thus aims to install, integrate and operate the world's first high-temperature electrolyser (HTE) system in multi-megawatt-scale (~2.4 MW), at a biofuels refinery in Rotterdam (NL) to produce hydrogen (≥ 60 kg/h) for the refinery's processes.

MULTIPLHY offers the unique opportunity to demonstrate the technological and industrial leadership of the EU in Solid Oxide Electrolyser Cell (SOEC) technology. With its rated electrical connection of ~3.5 MWel,AC,BOL, electrical rated nominal power of  ~2.6 MWel,AC and a hydrogen production rate ≥ 670 Nm³/h. This leads to GHG emission reductions of ~8,000 tonnes during the planned minimum HTE operation time (16,000 h). MULTIPLHY's electrical efficiency (85 %el,LHV) will be at least 20 % higher than efficiencies of low temperature electrolysers, enabling the cutting of operational costs and the reduction of the connected load at the refinery and hence the impact on the local power grid.
