Hydrogen fails at day/night balance

Hydrogen fails at the efficiency of the whole cycle from the electrolysis to the fuel cell at the day/night balance for solar electric power. Example with a sea water desalination system.






The hydrogen side of the caclulator is equipped with the dreams of hydrogen resarch, 85% elektrlolysis, 65% fuel cell and only 1000.-EUR pro kW fuel cell with 50000 hours usage time.

But even the optimistic dreams of hydrogen resarch fail against the new generation of lithium batteries at the total efficiency and the costs for more photovoltaic. Only the old opponent lead acid battery is here clearly beaten.

Lithium has the best expectations to solve our problems at our mobility and the day/night balancing of a photovoltaic oriented power supply.




  Lithium battery as electric power storage


Basic calculation models for lithium an electricity storage. The textbook to recognise early, at what applications is rentability already given, or is short before rentability.

OGRON new energy storage
A new dimension in application possibilities for lithium batteries promisses the company OGRON. First time are storage power plants mentioned as target market.


Storage crisis of renewable energy
The whole solar electric power and wind energy branch denies the storage crisis. The standard answers about the storage problem are easy to disprove.


Who sits in the glass house should not throw stones
In plain lack of knowledge about the storage problem, the say ''Atomic power highway'' or ''Atomic power refinement system'' about infrastructrue to store electric power.


Pump storage power plant
The storage demand for a bic scale enlargement of solar- and wind power is with pump sorage power plants not possible. New technology is indispensably necessary.


Lithium batteries vs Kaprun
How to compare lithium batteries with a pump storage power plant. What would it cost to built Kaprun new? How is the compare of costs?


Parameter for the storage of electric power
What are the cost criteria for an electric power storage? What are the costs to store electricity? Javascript calculator for the basic parameters to store electric power.


Sea water example
The sea water desalination is used as an example, how different electric power storage systems can influence the price for solar electricity.


Sea water desalination with solar power
So much sun, why are not all seawater desalination plants operated by solar electric power? The reason until now had been the parameters of electric power storage technology.


More important than photovoltaic for 1.-EUR Watt peak
Lithium batteries with extrem much load cycles in a price range around 300.-EUR per kWh capacity are more important for the price of solar electricity than photovoltaic for 1 EUR W peak.


The dream from hydrogen
In despair about the insufficiency of lead acid batteries as electric power storage, the dream from hydrogen and fuel cell started.


CAES costs
There are theories to make caverns in big salt layers for compressed air energy storages. This is to balance the wind energy. How expensive can a CAES be?
