Between dreams and realities in Germany

[sicetaitsimple]

The same thing happened between 2012 and 2015, when the price of US imported coal was low.
Shortly after, the production of electricity in Europe from coal fell...

Okay, okay.... It was rather the result of a European directive which authorized, by way of derogation, end-of-life installations not to respect the emission thresholds set, subject to not operating for more than 20000 hours. between 01/01/2008 and 31/12/2015.
Indeed in 2016 it went down because all these facilities had been closed at the end of 2015 or before.

4. Without prejudice to Directives 96/61/EC and 96/62/EC, existing installations may not be required to comply with the emission limit values ​​referred to in paragraph 3, and they may not be included in the national scheme reduction in emissions, provided that the following conditions are met:
a) The operator of an existing installation undertakes, in a written declaration presented no later than 30 June 2004 to the competent authority, not to operate the installation for an operational period of more than 20000 hours from January 1, 2008, ending no later than December 31, 2015;

According to this article from PV magazine, Germany would have installed around 1000MW/month of PV since the beginning of the year.
The question is, if it continues like this, what will they be able to do with it in the next few years on sunny days in the middle of the day?
Once the export interconnection capacities are saturated, which does not yet seem to be the case, internal solutions must be found. Especially since some neighbors are not left out and will have less and less interest in importing German electricity at the same time, having to manage their own problems.

From more con to less con
* surpluses, you can have none by disconnecting the central...
* you can dissipate your kWh in Joule effect
* you can make e-fuels
* you can electrolyze water and have H2/O2

Technically, there are solutions, that's for sure.
You are also forgetting the controlled charging of electric vehicles or stationary batteries, which is also a way.
The concern is "how much does it cost?", since with a rather oversized sunscreen, the "problem to solve" is only present for a few hours a day for a few months a year.

I am not sure that stationary batteries respond to orders of magnitude (we are talking about GWh).

If the cars were connected, maybe... at 100 kW, it takes 10 cars to absorb 000 GW.

I wrote "one way", and certainly not "The Solution"!
Besides, 10.000 cars is not much. How many EVs will there be in Germany in 5 or 10 years?
Regarding stationary batteries, I was not necessarily talking about domestic batteries.
Attached is a "position paper" from the Dutch "RTE" targeting 9GW of batteries installed by 2030.

9 GWh it seems?

[sicetaitsimple]

9 GWh it seems?

No, "TenneT needs around 10GW of flexible storage in 2030"

It so happens that currently the batteries used on the networks globally have a capacity of approximately one hour at full discharge because their main role is to meet the demands for primary and possibly secondary frequency regulation while waiting for controllable power stations to take over. relay.
But that does not prejudge their future use.

[Remundo]

I just read your document and nowhere are there mentions of GWh.

Which makes me wary. If it is implicit, it is quite confusing nevertheless.

[sicetaitsimple]

If it is implicit, it is quite confusing nonetheless.

That it is confusing is beyond doubt. The development of the electric vehicle (certain, but at what pace?), individual battery storage (in my opinion much less probable quantitatively) and network-type storage solutions are still very vague. And insofar as until now the existing European infrastructures (power stations, network) manage to do the job, there is a priori no urgency to hurry.
But when Germany decides in mid-2022 to install more than 100GW of new PV by 2030, that changes the landscape a bit...Something will have to be done....
