@@MB-xe8bb Well, most of the heat is used to create steam that drive a turbine that in the end will generate electricity from the generated heat. Since the heat is created by Nuclear Decay there is no CO2 emitted as that is a byproduct of combustion. The cooling towers of a nuclear plant are there to radiate out the waste heat which is to keep the complete system from overheating. However this heat is not enough to cause any problems to the environment. The issue there is that CO2 is really good at holding heat. What we're essentially doing when we burn something and we crete CO2 is that we are making a large blanket around the earth where the solar rays have a harder time reflecting back into space because of CO2 and other greenhouse gasses. The heat is essentially getting trapped in the earth's atmosphere hence you get global warming. The more CO2 and other greenhouse gasses we pump into the atmosphere, the bigger the warming will be. That is why Nuclear energy is so nice because it doesn't emit any greenhouse gasses in the production process of electricity where almost all other forms of electricity production do emit those gasses because they usually burn something to get the energy.

To get heat machines to work you need temperature difference. when you use steem turbine you add superheated steem one side and you got 45C watter another side 45C is more than 35C that is used in heatpumps to heat houses. you have like 4x8x6m storage unit 1m wallsthat have heatpump pipes around it to get hot watter constantly and that seals leaks. for example you need 50 000kwh a year 40k of those are hot watter and heating 10k electricity. Maybe to use peltiere elements to generate electricity is even better. The heating element can be molten salt battery buried inside sand so that innefficiency of that battery heats the sand in summer and day and night electricity difference gives you benefit. In Estonia currently it is hudge like 30-50€ MWh lets say you have 100kwh molten salt battery then got 15% of that energy as a waste heat into your sand and you can sell your solar at peaks or be totally off grid.

You don't need two weeks of storage. Even on cloudy days you get 20% power from solar panels. So you just over provision them by a factor of 5. This is viable because of how cheap solar panels are. Now you only need 1 day of storage. You can improve this further with geographically diverse wind and solar.

Yes, pumped hydro is an existing technology that will probably end up being the best solution to energy storage. It's capital intensive and takes a while to come online, but nuclear takes more capital and much longer to permit, construct and bring online. The other problem with safe nuclear is that the electricity it generates is very expensive compared to the combination of solar / wind and pumped hydro. Small, modular reactors produce energy that costs even more because they don't have the efficiency of scale of a large nuclear plant. Some innovative pumped hydro solutions look very promising. The first is river pumped hydro where the only storage necessary is the upper reservoir as water is pumped from a river and then delivered back to it. This can also be done with large lakes and even seas and oceans where the extra few feet of head provided by tides can be taken advantage of. The river system would also work with existing hydroelectric facilities where the upper storage, the lake behind the hydroelectric dam, already exists. If two dams are located close enough on the same river the water can be pumped from the lake of the lower dam up to the lake of the higher dam. But yes, pumped hydro is an existing, robust, low-risk technology that will provide the majority of energy storage long before most of these wonderful new ideas can be implemented at scale. P.S. And there are a lot more possible pumped hydro sites than you may think (616,000).

The problem is that sites built for a gravity battery don't actually work that well (such as the crane system - stand alone or in repurposed mineshafts). Natural water reservoirs do work well, but are obviously not abundant. If you wanted to build out pumped hydro you'd need a location with a lot of hills that could be worked/processed. West Virginia would be a great location if you were to build pumped hydro in locations already wrecked by mining, especially in areas of mountain top clearing. And West Virginia already sports a lot of wind power projects...

There are mitigations to evaporation, but they're not always feasible, depending on the size of the reservoir. Many wind farms aren't even near large water sources anyway, or elevated land for a reservoir. Now, that's when the compressed CO2 turning the wind turbines is a good idea.

Water can be pumped from a lower reservoir to an upper reservoir by power from the grid or these other sources, then used to power a hydro power plant when sources like solar are not available. This is already use in the San Luis reservoir of the California Aqueduct where hydro-power is from the outlet powers pumps to fill the lake.

In the 1980's I worked in the oil industry optimizing controls for Claus sulfur recovery processes. More recently I've worked with ammonium phosphate fertilizer industry controls where sulfuric acid (98% concentration) is produced to convert phosphate ore (fish bones) to phosphoric acid. Based on my industrial scale experience on the subject, I think this idea deserves to be "stored" indefinitely. The real trick to using sulfur for energy storage will be to convert SO2 back to H2S efficiently... maybe with iron sulfate catalyst. But then, where do you get the excess hydrogen? I too am a strong proponent for nuclear. I have a bit of experience with several PWR reactors in the US (over 4GWe total capacity). The future for nuclear fission, fusion, and possibly hybrids, looks bright.

One US university paper presented a promising rechargeable battery. Aluminium, urea water solution and carbon. By weight half energy density, 2 V cell voltage, not burning, and coulomb efficiency was excellent, promising good durability..The most expensive part is aluminium. It's freezing at about -10C, so not useable in many cases, but even in Finland it would work fine underground..

Multispectoral glasses must rotate the polarisation before the light reaches the sunglasses.

I'm pretty sure a brimstone energy source is basically the plot of Doom.

There is no existing hydrogen (or sulfur) infrastructure, but there IS a giant natural gas / methane one (and power plants that can use it). Concentrated solar is now a silly endeavor when photovoltaics is constantly beating cost records - nothing will compete with PVs in cost. This is why making methane with Sabatier reaction using purely PV source as electricity (no expensive grid electricity + no begging to connect solar farm to it!) is the most promising and most versatile solution. In fact synthetic methane from co2 capture may actually be CHEAPER in "a few years" than drilling. If that happens capitalism may solve climate change.

I don't think you understand the utter gigantic volume of CO2 in our atmosphere and yet extremely low concentration...in order for that to work, you would need highly concentrated CO2 in the first place, that idea is plagued by the same problem as carbon capture. Which is that humans so far haven't invented a financially efficient way to capture and isolate CO2 from the atmosphere, something required to make your idea work. Not to mention the extra massive energy/power required to capture CO2 and then to the required to use for that method to convert the gas (it requires high heat). Your idea is something that can come AFTER carbon capture becomes viable, and not before. I don't understand why the world's gas stations (oil/gas states) are not investing trillions into carbon capture research, it's the only way to keep their business future proof. Imagine selling all the oil and gas you want while simultaneously being responsible for capturing all of it from the air with solar power (most of these states are deserts). I think they are just frankly stupid, uneducated idiots sitting on top of temporary gold. The big human flaw of looking and thinking only about what's in front of you and not about the tomorrow. The funny thing is that they will absolutely come to this conclusion eventually but it will either be too late and they will go back to being empty deserts or it will be too late for this planet.

Energy storage is not necessarily needed. You just need to have installed almost twice the wind power capacity but spread out to a region with the diamater of big high pressure zones.

Would like to see an analysis of the tech from Antora (resistive heating of carbon so it emits light, capturing of the light through a solar cell when extracting the energy).

I’d love to see a video on iron oxide batteries, which you briefly mentioned. My understanding is that they should theoretically be reasonably efficient and cheap, with the downside that they’re large and heavy. Which means they are terrible for portable uses, but seem ideal for grid-level storage.

The concept behind solar and wind energy isn't when the sun doesn't shine and the wind doesn't blow. Those times are already factored into production expectations much the same as energy loss and inefficiency is factored into other forms of energy production.

I would love to see a video on the most recent data from the "hope vs hopium" paper just released which has quite a lot of climate scientists talking. I think we'll need cloud seeding, and a lot sooner than anyone expected.

The efficiency of the latest compressed air storage units is now high enough and relatively low tech so units can be casually dropped in as-and-where required even down to a few wind turbines, or scaled up much larger. But I guess those aren't flashy enough to receive government funding or research grants.

Far better to focus on Renewable Fischer-Tropsch Synthesis and "artificial photosynthesis"...You get pure, liquid hydrocarbon fuels that can be used in existing and advanced (higher eta) internal combustion engines and stored-transported with existing infrastructure. Let's all remember too that the transition to renewable (eternal) energy may give us a higher cost per unit of energy but we also have enough potential to make improvements in efficiency sufficient to compensate higher unit costs by reducing the units of energy we need to do the same things.

Nuclear reactors can't match the intermittent demand because they can't regulate quickly enough. Therefore, for them to be efficient, you'd also need storage, at least for day to day coverage.

You got me Sabine 😂 i am on sulfur storage wagon now

The solar power cannot be used directly with this heat storage, but it may be used indirectly, can it not? It just so happens, that photovoltaic power comes at the same time as normal solar heat power that is used for that sulfur storage. So... even though your photovoltaic may be too weak to use by itself, but it can surely be used to strengthen the power of already existing thermal storage, right? Adding few electric heaters to the thermal energy collector is extremely cheap, they can be powered by those photovoltaic sources nearby and I'm sure that their power will be used efficiently that way.

Also check out other liquid-metal storage mechanisms. Also fluoride salts.

So, in the US, Lead-acid batteries (currently used to power the 12v system of pretty much every car on the road) are recycled at over a 90% rate, some think even higher, and 98% of the battery material can be used post recycling. Why are we not mandating that replacement batteries must be some other chemistry like Lithium Iron Phosphate, nickel-cadmium, sodium ion or some other type of rechargeable battery chemistry and use the recycled lead-acid batteries as stationary grid storage until those other battery chemistry's become more mature and ubiquitous?

Plenty of sulphur deposited around the rim of active volcanoes. Personally, I'd take my energy from the magma. Don't dig into the volcano itself, however, like they did on Hawaii, unless you want to upset Pele. Yes, they were using magma heat from the sides of Kilauea. What could go wrong?

If we insist on forcing the square peg through a round hole that is wind & solar, thermal storage will be a must (imo). Even a week to ten days of storage would be a game changer. As for making the system work with existing renewable facilities. Because of intermittency, renewable facilities are overbuilt by a pretty significant margin. If we were to use the same technology that is used to turn boxite into aluminum to heat the sulfer, the loss of efficiency would be acceptable do to the massive over production of electricity on day when the facility is running near full capacity. I have no idea why we're still chasing batteries for large-scale storage.
