| Liquid tank for hydrogen
|

|
Linde shows a 120 litres liquid hydrogen tank in Hannover. 90 kg weight and up to 8 bar inside pressure to have not to blow off the evaporated hydrogen immediately.

This construction for a high pressure hydrogen tank is suitable for 700 bar. The biggest model has 32 liters of contents. 5.4% of the mass are stored hydrogen.

| Self discharge: 100% in 14 days
|
|
|
Another quality criterion for batteries is the self discharge. This determines how long a battery can be stored and how much power is necessary to hold the charge.
|
| Battery technology electrolysis and fuel cell
|
|
|
Hydrogen with electrolysis and fuel cell must be seen as a battery technology. Electric power is used with the electrolysis and is taken from the fuel cell.

Only 3.4 kgs of hydrogen instead of 4.6 kgs in liquid hydrogen tank. For it, however, no losses by vaporization. For opportunity drivers on short distances the better solution.

| Scooter: battery or hydrogen

|
|
|
Each of the 4 bottles has 2 litre volume and can be filled wiht 700 bar. This should give 30km range per bottle to a scooter. Exchange price 20.-EUR per bottle.

Only the frame with the hydrogen tank was to see in Hannover. Around this will be a built up a scooter with fuel cells. The hydrogen bottles are to be exchanged.

The 5 liters hydrogen bottle contains with 200 bar compressed 1 m³ hydrogen. This are 2.97 kWh of chemical energy or about 1.25 kWh electric power from the fuel cell.

Here built into an Opel Zafira. However, with 4.6 kgs about 400 kms of reach, for it hydrogen gets lost constantly by warming in the tank and the vaporization resulting from it.
