About NEPTUNE
The NEPTUNE project addresses challenges associated with reducing capital costs, and increasing production rates and output pressures of water electrolysis that will be required to achieve large-scale application of PEM electrolysers.
The NEPTUNE project will develop a set of breakthrough solutions at material, stack and system levels to increase hydrogen pressure to 100 bar and current density to 4 A/cm2 for the base load, while keeping the nominal energy consumption less than 50 kWh/kg H2. The novel solutions will be validated by demonstrating a robust and rapid-response electrolyser of 48 kW nominal capacity with a production rate of 23 kg H2/day.
