Good news about the thermal storage projects, thanks! 👍

Call me suspicious, but I would love to see the feasibility study for that water storage system. For example, I make the capacity of that underground pool 60 GWh not 90 GWh, and that is before losses.

Can't they heat the air with mirrors to concentrate the sunlight, rather than with resistive electric heating?

Thank you for the commentary. This is good news. A basically simple principle. Have you covered the MIT Concrete battery? Massive concrete structtures could serve double duty.

Dave I haven't watch this yet just wanted to suggest a content idea. I would like more on how the developing world is leapfrogging centralised fossil fuels energy (like they are doing with cell phone coverage which is enables the next step). I've seen a lot of small scale ideas that will give individuals and households clean safe energy. Electric taxi bikes, home solar+battery no cost up front with micro payments, electric scooter batteries powering small businesses and homes during daily grid outages. They are skipping large scale infrastructure, this seems to be a tsunami of small decentralised and democratised energy generation that most in the west have no clue what's happening. I'd like people to just have a think about this.

Thanks for pointing out that we here in America are way behind the times when it comes to our units of measurement. Someday we will catch up. Meantime, keep up your fine work of informing us of the latest climate and energy news. 🎉😊

Kind of like geothermal, but requiring the energy be first input. Hey, whatever works

You have clearly done as much research on MMT as Warren Buffet has done on Bitcoin. You do not grasp even the core concepts of MMT. That’s your choice, but shame on you for adding to the social media noise instead of actually doing real research and making a real contribution to the discussion.

The weakest link will be the self-serving politicians

Those wind turbines have become completely market driven here in Finland. Many small --- and i mean small -- counties get a bunch of their communal revenue from building turbines and selling thhe electricity to locals or neighbouring counties.They are economically self-sustaining and don't need government subsidies.

I lived opposite an industrial plant for a few years, which had to go to enormous lengths for cooling processes. On the other hand, I vaguely remember hearing about the Netherlands, where industrial waste heat was used to keep bridges and roads free of ice in winter. Why aren't local authorities and all industries consistently thinking about different models of mutual co-operation? Tax relief could be granted to companies as payment models. Creating the infrastructure would be a municipal task, i.e. tax-financed, and the subsequent savings would then benefit the citizens, who would have to provide the tax revenue. Of course, depending on the projects that were created, street heating would not be the first priority - rather, for example, energy generation by converting waste heat into electricity, or water heating for heating and hot water in neighbourhoods directly adjacent to the respective industrial plants (including smaller ones ...) in order to eliminate long transport routes. Just a thought ...

From a technical perspective, the efficiency of systems like these appears to be a great advantage. My concern is economic - we need to make sure that natural monopolies like these are run as a not-for-profit public good with complete transparency and without subjecting captive customers to pocket-picking profit-taking. It’s fine to issue government bonds to finance them, but repayment to investors must be limited in time and amount. These projects cannot be allowed to be infected with ‘privatization’ (when users have no fair market alternatives, that’s profiteering). I hope both the engineering and economic challenges can be worked out.

Interessting concepts. They show us what can Happen If people use there brain. In the end they will proof the change is possible.

I don't understand why people are not moving to the more energy efficient underground buildings. Building on the surface is the most wasteful aspect of this civilization.

water batteries, sand batteries and all the other forms of storing electricity but i don't see them here.

Brilliant. Keep it simple

Ridiculous !

I live in the UK in Essex (Basildon) and our estate (1973 build) was designed by a Scandinavian architect and we have a central estate heating system where the water and heating is run by a system that uses high pressure steam. In the recent years its changed from gas and oil to create the steam. I think the idea is great, but using oil or gas has its problems, our heating the last 2 winters has been expensive, the council bid for the current fuel at a price that was massively affected by the situation in Russia, so this system would suit our estate I'm sure.

kzbin.info/www/bejne/gKrOdWuLgNumbNksi=oZhPu1rE71ZibHah. This is a distributed energy storage system in Canada

Well done, as always. We rarely thank or pay homage to KZbin for providing a platform that allows the greatest cross-fertilization of ideas in human history. Take a bow, KZbin!

"For those of you who still use the wrong calibration system". Brilliant

Oppenheimer I have Almost Less things to say against you when you Go Basics than when you try your Best and Fail Successfully... [ Could be Improved...wanna Hang? I beat you than your Sister... Imagine Thinking about the Perfect LaRoche Cream with her...]

Short and sweet. Costs per Watt would be good even if very approximate? Thank you Dave and your super Patrons

90Gwh battery. Bet that still wouldn't get a Tesla from London to Manchester without stopping to recharge.

It's not like these are bad ideas, It's just that they are not very helpful. Your not going to get people ripping down infrastructure and redoing housing to implement this so it's pretty much stuck with new builds. That's not going to make a hill of beans difference in the time frame needed. But A-Ok with this. Makes good sense in the long term.

So be an American is being a wrong-un...😮

Couldn’t more industry use these kinds of storage with their own waste heat to save money on their own plant’s needs then? Hmmm

Does sand have that kind of thermal capacity? Guess it must! Cheap enough, although sand isn't as ubiquitous as it used to be... Add this to geothermal, and it sounds great....

I see a lot of press about the failure of electric cars and how auto manufactures are planning to sell internal combustion engines for far longer than we thought. evidently cheap exports from China are having a dramatic effect all over the world. Can you please take a close look at what is going on?

For 2 fukin years I was commenting on every blog, KZbin channel to build sand batteries like Finland does! HALLELUJAH! 👍👍💪

90 gigawatts? That's probably enough for my space heaters and steam pumps. ;*[}

Thanks for the new video! It's nice to see Polar Night making progress. Maybe Finland can be an example for the rest of us. District heating makes so much sense, it's just the efficiency you get from scaling things up.

Always happy to see your videos

The subtitles are trolling Finns ngl

Dave, Have you seen Kensa's quite sensible scheme for using a low temp district heating system? Essentially this uses a low temperature distribution system which doesn't need insulation or fancy pipes to distribute water at a very modest temperature around an urban network. Each house then has what amounts to a ground-source heat pump to boost the temperature to what is needed to heat that particular home. The heat pumps work with a very high COP, seeing as the temperature rise is very modest. The individual home owners retain control of their heating. What's not to like?

I'm a bit skeptical concerning energy transition. All we've been doing so far has been aditionning every energy sources for forever increasing energy consumption. Still a great news though. Thanks for sharing.

The north Europeans seem so innovative. As an environmentally conscious german I'm enve

In Minnesota I lived in a place with district heating and cooling and it was great. It was included in the rent which made for a nice cool summer. Would recommend.

Finland is awesome.

Taking very low entropy electrical energy and converting it into high entropy low temperature heated water is wasteful. For building heating it is fine but all the buildings need to be connected with pipes which cannot be done for spread out cities. It cannot economically reconverted to low entropy electrical energy without very low (like 30% or less) efficiency.

It’s bad form to insult your audience members who aren’t communists.

I think it should be possible to pull heat off buildings and roads.

It's still frosty! This spring has been crazy cold (Finland). Great tech too, sand batteries

Thanks

Keep posting positive news, when possible!

In the end, it is money. Forget politics. The only things that happen, happen because of money. Politicians can jump into the ocean. If it is more profitable, that's what will happen

Fahrenheit the "wrong calibration system" Haha. I love it. The temperature in Latin I call it.

If memory serves me right Vantaa isn't exactly a small town either. Not even by Finish standards. How very Finish to just go ahead showing how things can be done whilst others dillydalling still around.🤷‍♂🤘🤘 As for Bristol, 10 or so years ago, a couple of 60's high rises down the road from Temple Meads were all modernised inclusive of a local district heating network being put in place. I worked at the time for a company installing a 1 MW biomass boiler in one of the high rises.

Can't help wondering the heat loss during the transmission to homes from the storage. How do they manage to insulate these pipes. What is the % of loss? I am sure it is connected to the distance too.
