Project Overview

---

 

The overall objective of the project is to develop an advanced water electrolysis supplied by renewable energy as the foremost technology for producing “green” hydrogen for fuel cell vehicles. The ability to follow rapidly an intermittent load makes this an ideal solution for grid balancing. To achieve large-scale application of PEM electrolysers, a significant reduction of capital costs is required together with a large increase of production rate and output pressure of hydrogen, while assuring high efficiency and safe operation. To address these challenges, a step-change in PEM electrolysis technology is necessary.
The NEPTUNE project will develop a set of breakthrough solutions at materials, stack and system levels to increase hydrogen pressure to 100 bar and current density to 4 A.cm^-2 for the base load, while keeping the nominal energy consumption.

Starting date: 1st February 2018 - Duration: 3 years
