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.

  • Why are in sunny countries Diesel generators working?
  • Why do new cars not drive with electricity from renewable energy?
  • Why do new trucks not drive with electricity from renewable energy?
  • Why do ships not drive with electricity from renewable energy?
For all questions is a single answer, the storage crisis of renewable energy. Electricity from sun and wind has to be consumed immediately or stored. Is there no storage, renewable energy remains a niche product.

  The grid as storage

When You ask employees from companies doing solar and wind energy, You will hear "We have the power grid as storage". How does this work? When the sun shines or the wind blows, we switch off caloric power plants. Very nice, we have at a honest extension of renewable energy in Germany 80 GW wind energy and 160 GW solar energy in in the foreseeable future. That would be theoretical 45% of electricity. Theoretical, because what happens at a sunny and windy day? 240 GW are feed in the power grid. How to switch off 240 GW caloric power plants, when only 90 GW are on?

  Storage power plants

The fan of sun and wind brought so in embarrassment means. "We have storage power plants". A famouse example for this is Kaprun. 130 MW for pumping up the water., so for 150 GW we need only 1154 times Kaprun. Yes, but Kaprun has 330 MW power production, lets increase the pumping to 600 MW. Great, now we need only 250 times Kaprun!

Where to built 250 times Kaprun? To illustrate the problem, here the fight between more water power and landscape protectors.

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.

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.

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.

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?
