Proposals should address the following:

• Design and operate an innovative compression system to fill trailers for a daily capacity in the range of several tons/day in a certain geography;
• Deploy safety concepts to operate safely the filling centres, on road transportation and the HRS at high pressure inlet;
• Demonstrate the economy of scale due to the high pressure at the filling centre (increase of trailer payload) and at the HRS (reduced compression need), and reduced tube trailers rotations logistic pressure by increasing the trailer payload and improving the HRS capacity due to the high-pressure inlet. The project should include a techno-economic assessment of the concept of the filling centre (lessons learned, costs that can be optimised, impact on the final price at the nozzle, different possible configurations. modularity etc.);
• Demonstrate a complete logistic scheme with a distribution radius at relevant scale (minimum several tens of km);
• The demonstration of the filling centres and HRS interoperability (among the commercial actors aiming to participate).

In addition:

• Due the high-pressure operation a special attention should be paid to the safety measures around filling, connecting and driving phase;
• The management of the gas purity in accordance with latest ISO specifications should be demonstrated in order to secure the right operation of hydrogen vehicles;
• As this demonstration is combining 3 different items (filling centres / high pressure trailers / HRS) the mechanical and digital interfaces should be demonstrated properly and fully mastered through an overall quality system;
• In order to improve the GH2 logistic costs, the project should use the latest available technologies available on the market or under development. In particular, it should include innovative components and subsystems developed in the frame of previous EU funded projects for both infrastructure (innovative compression solutions, filling protocols) and trailers;
• The filling centre should demonstrate the distribution capability to two HRSs minimum;
• The filling centre should fill trailers at high pressure (to be defined in the range of 500 to 700 bar) with a hydrogen payload in the range of 1,000 to 1,500 tonnes.
