The NEMESIS2+ project which received funding from the Fuel Cells and Hydrogen Joint Undertaking (FCH JU) has been successfully finished. The consortium was able to show stable direct steam reforming of diesel and biodiesel with the newly developed prototype unit. For more details please refer to the final project report. Thank you for your interest in the project!

Currently, large-scale methane steam reforming is the prevailing technology for hydrogen production. In the transition towards a sustainable hydrogen economy with a fully functional infrastructure, decentralized hydrogen production at refuelling stations will accelerate market introduction of hydrogen-powered vehicles. On-site hydrogen production at refuelling stations is economically reasonable especially in areas where hydrogen can not be cost effectively supplied by a central production plant. Such technology has not yet been developed to a commercially available product fulfilling the requirements of the market in terms of cost and efficiency.

The NEMESIS2+ hydrogen generation system consists of a desulphurization module for liquid feedstock (diesel/biodiesel) followed by a reformer module, where catalytic conversion is accomplished by steam reforming with subsequent water-gas-shift reaction. A pressure swing adsorption unit (PSA) will be used for hydrogen purification. The system is equipped with a dual-fuel burner which enables to run the burner on off-gas from the PSA as well as on liquid feedstock. The purified hydrogen can be compressed and stored in a tank before it is fed to the dispenser for refuelling cars.

Using liquid feedstock in combination with steam reforming technology allows for operating the system at high pressures of 12 bars resulting in significantly reduced system size and hydrogen production costs. With the envisaged process concept a system efficiency (LHV(H2) / LHV(fuel)) of higher than 70 % can be achieved. The expected production costs per kg H2 are expected to be lower than 4.00 € per kg of hydrogen.
