Hydrogen refuelling stations

There exist two principle concepts for a filling station, the multibank system and the booster dispensing system. 

The multibank dispensing concept is similar to the one used in most natural-gas filling stations today (see Fig. 12.8). 

The filling procedure automatically follows three steps (for the example of a filling station for vehicle tanks with 35 MPa)  

Hydrogen flows from the low pressure bank to the vehicle tank until a pressure of about 10 to 15 MPa is reached in the vehicle tank (or the pressure in the low pressure bank is reduced to 16 MPa). In fill mode, the low and medium pressure banks are filled to the same pressure of the high pressure bank, to reduce the filling time and to make the maximum use of the storage vessels. 

Hydrogen flows from the medium pressure bank to the vehicle up to 20 to 25 MPa.

In the United States so many vehicles operate on hydrogen fuel cells (sec Box 12.1) that hydrogen refueling stations have opened in many cities, including Washington, DC.

An onboard hydrogen tank has several problems since hydrogen leaks easily, is hard to store and hard to compress and burns quickly. Overcoming all these concerns has been expensive but most of the major auto companies has solved these problems for the most part in their prototype fuel cell vehicles. Refueling tends to be difficult although there are now a number of hydrogen refueling stations in use around the world. 

Chapter 12 discusses and analyses the different options for hydrogen distribution -pipelines and trailers (including liquefaction) - from a technical and economic point of view, in the same way as the hydrogen production technologies in Chapter 10. Further, different hydrogen refuelling station concepts are described and the necessity for the development of codes and standards addressed. 

Figure 8.3 shows the global distribution of existing hydrogen refuelling stations. Black spots represent operational stations, grey spots, planned stations and white ones indicate expired stations.

This technology will allow for a very efficient transition from fossil fuels to hydrogen. If a driver runs out of hydrogen and there is no hydrogen refueling stations at hand, he/she can continue driving with gasoline.

The level of involvement of Spanish car industries is also increasing, as well as other industries as industrial gases, utilities and renewals. Spain participates actively in transport demonstrations with seven hydrogen buses running in Madrid and Barcelona, where there are two of the first hydrogen refuelling stations in Europe. 

Development and construction of an HFC urban bus for Madrid. The main objective is the demonstration of the technical and economic viability of an advanced fuel cell propulsion system combined with innovative vehicle concepts for public transport application. This work was done in combination with the ES Hj Hydrogen refuelling Station in Madrid.
