HOW TO FILL THE VEHICLE WITH HYDROGEN
ROAD FILLING STATION – H2 PRODUCED BY ELETTROLYZER
In one or more 20’ container box (according to potential H2 capacity that we want ) the following components are installed
H2 GENERATION UNIT working by means of Electrolysis. This system (compared to Reforming, suitable only for big productions) can be started and stopped automatically in any moment, for several times without the need of particular proceduresi and without the assistance of an operator. It is surely the more simple and safe system and the more suitable to the productionof Hydrogen by means of Alternative Energies (wind and photovoltaic).
A PURIFICATION DEVICE acting as DRYER to make sure that Hydrogen is free from hunidity and Oxygen.
A COMPRESSOR to compress H2 up to 200/220 Bar(Pressures authorized nowadays in Italy). Higher pressures will be authorized in the future. We are waiting for the Norm that will allow 360 bar pressure.
SAFETY DEVICES that are controlling production, purification, compression and delivery.
A GROUP of containers (optional for smaller stations) for the storage of H2 ALLOWING THE CONTINUOUS PRODUCTION of H2 in the 24 hours , regardless vehicles filling time.. Such filling times are similar to the one needed to fill the cylinder of a CNG vehicle.
AGT Hydrogen INTRODUCES A RANGE OF STATIONS HAVING VARIOUS CAPACITIES’ ACCORDING TO THE NUMBER OF VEHICLES SUBJECTED TO BE FILLED WITH HYDROGEN AND HYDROMETHANE.
Please keep in mind that for the models MC4 – MN10 – MM20, in lack of storage, Fire Prevention Certificate may not be required.

DH60 ROAD HYDROGEN STATION type 60/200 (capacity 60 Nm3/h)

HH100 HYDROGEN ROAD STATION type 100/200 (capacity 100 Nm3/h)
With 100 Nm3/h in 24 hours 2400 Nm3 H2 can be produced, suitable for 80 filling to FIAT Multipla or 132 to FIAT Doblò or in case of ACNG+H2 (Hydromethane) to: 266 filling to FIAT Multipla, 444 to FIAT Doblò, 600 FIAT Panda, 480 Mercedes.
It would be antieconomical “, useless overall, to think to install from the beginning stations of big capacity in area where vehicles running with H2 and CNG+H2 mix “ARE STARTING “ to be on the road. We suggest therefore to “START” with SMALL CAPACITY” pumps (MM10 o MA20).
The small elettrolytic H2 stations are assembled on SKID or in container when the H2 request in the area is increasing, can be quickly replaced with larger models and then displaced in other zone where H2 propelled vehicles are starting to be on the road.
For cylinders charge , a H2 delivering column is used, having pistol very similar to the one used for CNG but obviously specific for Hydrogen. Also the timing needed to make a filling fare “il pieno” is similar to CNG ( 3÷4 minutes).
From the application of current Norms (Law Decree published on Official Gazette N°213 dated September 13th 2006) the Box for Hydrogen production can be installed in the existing Fuel Stations (or for small fleet in private spaces, judged suitable by VVF and ARPAT).
It would be appropriate that in very big towns, in order to avoid to the vehicles to run long distances to reach the outskirts of the town, the competent Authorities would allow the positioning of the H2 Station in strategical central points such as public gardens and green areas
Esemple: Sempione Park and former General Fruit Market in Milano; Eur and Olimpic area in Rome, Cascine Park in Firenze, etc..
POSITIONING OF THE ECOLOGICAL FILLING STATION
The Norms nowadays are making compulsory the positioning of Low Impact Fuel Delivery Stations (Methane, LPG,) to be placed on the outskirts of the towns obliging the environment-friendly driver to run for several kilometers from town center to reach the filling station.
Such norms could make sense years ago when danger risks with inflammable gas management was higher . LPG and CNG proved to be SAFE nowadays and therte is no more need to relegate Gas filling stations
in the outskirts
Even for H2 (who has energetic power 2/3 lower than CNG) it is necessary to overcome the idea of the “very dangerous” (named “Zeppelin effect”) and avoid toh ave H2 penalized by an excess of safety criteria (distances inside the station, positioning in the outskirts, ecc).
It is necessary to ease the filling to the category of drivers that are using vehicles mainly in the town that will hardly choose environment friendly cars if they are forced to go out-town to do an environment-friendly fuel filling.
We wish to remember hereby that from the year 1900 soon after 2° world war, that is before “methane-wide-use” , the so called “town gas” it was a mix of H2 and CO.
In this first phase of “adaptation” to H2 the following vehicles have been used : FIAT Multipla, Mercedes E, Mercedes B, FIAT Panda, FIAT Doblò.
Besides the vehicles charged with CNG that are designed toh ave on board cylinders for compressed gas, other that can be modified for H2 are the vans used in city centers (such as DHL, Mail Service etc.…). These vehicles today are all front wheel drive and therefore with loading plane very low; therefore cylinders can be positioned on the loading plane and the goods be loaded on a 2° plane . The volume loss it is about 0,5 m3 (25 cm of loading plane)
H2 FILLING STATION FOR SINGLE VEHICLE OR FOR SMALL FLEET
Beside the installation of proper Road Service Stations , AGT Hydrogen division is in a position to supplì systems allowing to fill single vehicles or small fleets.
Since usually 95% of cars is not on the roads during the night, it could be quite economical to fill-up hydrogen at running costs lower than diesel , without creating problems of electric energy supply. In fact electric energy producers are facing technical problems during the night to decrease the energy production (because electric energy generation system is very rigid )and therefore holiday and night supply is promoted by application of special discounts up to 50% to the users ( chemical industry, iron industry, ecc. )
Another solution is to use PHOTOVOLTAIC panels that nowadays have quotations 10 times lower compared to 10÷15 years ago.
It is possible to purchase a photovoltaic group of 1000 kW at a price of about 500.000 euro against 6÷8 milioni of 20 years ago.
