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.

Where is there natural occurence of hydrogen on the earth? Nowhere! One can produce hydrogen from fossil gas occurence, but then the hydrogen is a fossil energy source like natural gas. One can produce hydrogen with electrolysis from water, but then is hydrogen is nothing else than a battery technology.

Batteries are charged by electric power. Batteries deliver electric power by discharging. But You never take out more electric power from a battery than previously stored. An essential quality criteria of a battery technology is how many percent of the stored energy can be recovered.

Huge loss chain with the hydrogen

electrolysis
liquefaction to -253 degrees Celsius
energy for the transport to the gas stations
energy for the preservation of the liquid state in the tanker
storage in the gas station with the power demand for the preservation of the liquid state
efficiency of the fuel cell

30% of the electric power for the electrolysis up to the power at the wheels is estimated very optimistically. To keep the hydrogen liyquid in the tnak is an other source of unbelievable losses: the vaporization

Hydrogen
	Where will hydrogen as a storage medium determine our energy future and where will the hydrogen technology fail by more suitable methods?

Hydrogen fuel cell vehicles
	Directory over all our reports and comments about the hydrogen fuel cell technology in the field of mobility

Hydrogen tank and infrastructure
	How is it possible to distribute hydrogen to an gas station net and to store in the vehicles tanks? How real is hydrogen technology for mobility?

The hype about hydrogen
	The author of our recommendet book Joseph J. Romm was advisor in the hydrogen and fuel-cells program during the term of office from President Clinton

2,359 kWh per liter of liquid hydrogen
	The tank is a main problem with the hydrogen. Hydrogen boils with -252,76 degrees Celsius and in a liter contains only 2359 Wh chemical energy.

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.

False investment hydrogen research for fuel cell cars
	If all the billions for the hydrogen research would have been invested for better a lithium battery technology, we would already have hybrid cars to go 80% by electric power.
