Three weeks is not enough to seasonally move spring surplus to summer demand.

Those places with more hydro power than people will always have a surplus, the question to ask is could they do it without hydro power?

Porsche Says Its Synthetic Fuel Could Make Gas-Powered Engines as Clean as EVs
"The fuel is less complex than traditional gas—eight to 10 components compared to 30 to 40—allowing it to burn cleaner, with fewer particulates and NOx. Because of this, the total carbon footprint of the vehicle will be equal to that of an EV. "
One of the interesting attributes of power to liquid fuel, is that the process of creating
your own hydrocarbon from hydrogen and carbon, makes only exact chains,
so all the fuel is premium high octane.
I am guessing that Porsche's e-fuel is something made from natural gas, but
still very low emissions. Actual power to liquid fuel, would have net zero emissions.

I think electric drives are great, I am not sure the energy for those drives will be carried in batteries,
short of a massive improvement in energy density.

Why do you have to move spring surplus to summer demand? That solar panel and concentrated solar power produce the most during sumer time. While it power stations that risking breaking down during hut summer days then the demand is the highest. There climate change will make those heat waves a lot more common.

Intense Summer Heatwaves Rattle World’s Power Plants

Scorching temperatures during the summer of 2018 forced a swathe of power plants across the world to reduce power or shut down temporarily, owing to warmer-than-usual temperatures of cooling water and other general heat-related issues.

Spring has lots of days with plenty of sunshine, but no need for cooling, during those time surplus power, beyond demand
will be generated as solar coverage increases. The excess will have to be dealt with, in any case, it might as well be stored
for some later use, rather than be disposed of as heat.

You are not an owner ether, you drive a hybrid, that could run on gasoline.
The pure battery electrics have some serious limitations, but battery density is at the top of the list.
Imagine if the energy were carried as hydrogen in that new powerpaste, and fed into a fuel cell?
or regular gasoline with an onboard steam reformer?

1.4 million Plug-in vehicles. That includes plug-in hybrids. These hybrids give the owner a taste of driving on all-electric. My next car (or maybe a pickup) will be all-electric. Anything that can drive over 100 miles without a recharge is more than enough energy density for me. Most of the less-expensive less-battery electric vehicles are now getting 200 miles. If one wants more battery power, they can get over 300 miles. Personally, I wouldn't want the added weight. All the advantages of EVs, ar outweigh any concern of range.

1. I can power with renewables. Once the renewables pay for themselves (average of 7 years). It's free fuel for life! If somebody told you, for your gas vehicle, that if you pay up front for 7 years worth of gasoline, your gas will be free for the rest of your life, would you do it?
2. Much lower maintenance.
3. Much more efficient, with regenerative braking.
4. Superior torque, which gets you places quicker. Less time behind the wheel, and more time to do what you want to do.
5. No time waiting at gas stations. More time to do what you want to do.
6. Quieter, smoother ride.

Let me fix that statement for you, That includes plug-in hybrids. These hybrids give the owner a taste of driving on all-electric, without the risk!
I agree that electrics are a much better drive system, but think that batteries may not be the best way to carry the energy.

Risk? With a gas-guzzler, you plan your driving, and fill up with gas accordingly. No different with electric. One difference, every day you get home, you plug it in. Depending on the programming in the vehicle's computer, it can charge immediately, or wait til midnight. In other words, whenever you leave the home, you have your 200-mile capacity of charge.

Except with a hybrid you are limited to that 200 miles, are you?
It is one thing to talk about living within the limitations of a battery electric,
and likely another thing to actually do it.

I'm assuming you omitted the word "not" in the first sentence. A 200 mile limitation is not a "risk". One plans accordingly. Personally, I can count on ONE FINGER, the number of times per year that I travel over 200 miles.

The infrastructure, and charge times need improve a lot, before it will be equal to a fuel vehicle.

So is owning a fossil fuel cars. Think for example the massive cost and risk of being dependent on fuel from the very unstainable Middle East. There you both have had costly wars like the two Iraq wars as well as oil crisis with spiking oil prices.

Also the massive risk from climate change that fossil fuel cars contributes to.
