there are some interesting non-lithium batteries, like gravity batteries

Looks like a computer simulation have any actually been built? I suspect efficiency would be incredibly low, but then again they do pump water back into hydro electric dams off peak so as better to handle peak demand so maybe.

They won't use photovoltaic deivices but use solar thermic generation which allows for energy to be stored (IIRC in the form of molten salt, but I forgot the details), so that you can generate electricity even at night. This was considered already several years ago but the project was dropped due to political risk (think e.g. of the turmoil in Libya etc.).

We have such a power plant in the Negev desert: 240 MW power and 4.5 hours of energy storage. Ivanpah in California has 380 MW power, and the one in Morocco is the largest in the world with 510 MW. 

 

For comparison, one nuclear reactor in the Russia-occupied ZAES power plant is 1000 MW, and there are 6 of them.

No, quite high, 80-90% efficiency complete cycle, which is similar to the best batteries.

There is a prototype in Switzerland and works as expected. They now want to lower costs by reusing mine shafts instead of spending money on towers.

The trick for profitability is to avoid building tall structures and to avoid frequent replacement of cables. All the rest is proven.

I think Europe should subsidize this, as it avoids importing lithium.

 

This should outlast lithium batteries, uses no rare materials, it's easy to scale up, works in small scale, can be optimized for output power or other metrics... it's really a good concept, although it might not be cheaper than lithium...

Hahah! Russians leave snake island!

Many commentators have been predicting in the past weeks that Russia's invasion was about to peak and within July/August they would be in deep trouble!

typical biased reporting. They forgot to mention that Russia claimed this being a show of goodwill to enable food exports. Whether that's true or not is another question, but it should be part of the story.

It is part of the story in other reputable news, but who believes anything that lying, murdering git says anyway? A sign of goodwill would be to retreat and end the disastrous war he started NOW.

If I lived in Oldenburg, Jurgen would be voted out of office.

Did he ask anyone if they supposed such measures or he just 'assumed' he knew best?

I have no problem if he asked the local population, but oh so many of these people just do what the hell they want.

 

"Storage levels in February were less than a third — in part the result of what many experts say was an intentional move by the Kremlin as it prepared for war."

And who exactly allowed the the gas storage facilities to be sold to the supplier of the gas, Gazprom?

Who made no regulations until this year about how full those storage facilities were, and then later had to nationalize them anyway to ensure this was the case?

 

Russia is going to screw Germany over energy. When the price of gas increase N times (x3 or x4), gas demand will drop like a rock. We will have a hard winter ahead.

Why. Ot simply approved Nordstream 2? Isn't it bizarre that Habeck is claiming that Putin refused to deliver gas, while the German regulator at the same time refuses to allow deliveries through an idling pipeline which Putin has offered to use for deliveries?

Could it be this forum has been targetted by Russian hackers?

 

Naw, even they couldn't fuck up this bad
