The world’s first molten salt battery is turned on in Denmark
the world’s first molten salt battery is now running it’s now an operation and it’s actually working incredibly well molten salt batteries are a new kind of battery that can potentially replace lithium batteries for energy storage hello my friends welcome to the channel I’m Sam Evans you’re watching the electric Viking it’s great to see you on this channel we have looked at different battery chemistries many different kinds of battery chemistries many different kinds of potential new batteries which can change the energy grid worldwide one of those is molten salt batteries the world’s first molten stal energy storage battery has been launched in Denmark and this facility will store excess renewable energy from solar in particular but also wind during Peak periods and release it when production dips of course the nighttime would be common Danish company Heim energy launched the world’s first energy storage project using molten hydroxide stalt to store green energy the project is called molten salt storage or Moss Ms and the energy storage facility has opened in Denmark saen Gade chairman of the Danish Parliament and Port esberg officially inaugurated the facility at a ceremony hosted by Semco Maritime a key challenge in adopting green energy is we need batteries to store it solar is incredibly cheap if it’s never been cheaper than what it is today it’s much much cheaper than coal for example but here’s the key issue storing that energy we make huge amounts of power during the key hours of the day right between say the hours of 10:00 a.m. in the morning and 300 p.m. in the afternoon but a lot of that energy just has to go to waste because there’s no way to store it well that’s changing now the output of massive massive batteries has grown over the past 12 months by around 300% worldwide but most of those batteries have been lithium there’s not many batteries that have been deployed worldwide that were not using lithium High Energy’s molten salt battery stores Surplus energy prod produced during Peak periods within molten hydroxide salt and the Moss is a giant super efficient battery that competes with lithium ion phosphate this new facility will store energy from renewable sources um like wind and solar but also potentially other renewable sources as well such as geothermal energy during High renewable energy generation periods Surplus electricity will be used to heat the hydroxide salt which turns into a molten State the molten salt held at extremely high temperatures stores huge amounts of energy and it can store that energy for a very long period of time according to ask Emil L sh Yensen CEO and co-founder of high energy future commercial Moss facilities can store Green electricity in molten hydroxide salt heated up to 700° C on a GW hour scale so these batteries can be massive as big as you want them to be by storing green electricity in molten hydroxide salt no lithium is obviously needed and these batteries could potentially be cheaper the energ drawers facilities create a reliable and sustainable reserve for the time when renewable energy generation is low and of course that is in particular at nighttime when renewable energy production drops Moss batteries come into play the stored heat in the molten salt is released this thermal energy can be efficiently converted into steam and that steam obviously propels a turbine which creates electricity molten hydroxide salt is remarkably heat resistant this trait allows it to store immense energy reserves with very minimal loss this stored energy presents a viable alternative to fossil fuels in power plants and even heavy Industries like manufacturing now the company believes that this battery it should be used worldwide it makes sense in their opinion and they think it’s a better option than lithium batteries we are setting the stage together they said not just towards 2030 but towards a CO2 neutral 2050 by proving that groundbreaking Technologies can change our world to towards a more sustainable future said the CEO of this battery company Moss technology holds a potential for decarbonizing numerous energy intensive Industries heat consumption comprises 50% of total energy usage globally while accounting for 40% of carbon emissions by offering a green alternative to traditional energy sources for heat generation Moss technology is possibly a a solution to having cheaper energy storage batteries and not only that but the potential for these batteries to last a very long time is also a part of the enormous benefit of these battery packs now apparently they believe they’ll last about twice as long as lithium even as a lithium ion phosphate batteries so even if it costs a little more to build out these new batteries the fact that they’ll last for so long potentially 30 or 40 years would mean this type of energy storage is a crucial part part of the global energy picture and absolutely could we see these molten storage batteries molten salt storage batteries become a thing in other countries around the world well I think we should it makes too much sense the fact we don’t need lithium it uses abundant materials like salt and the fact that this heat can be stored for long periods of time with such little energy loss it just makes too much sense guys what do you think is this a good idea let me know in the comments thanks for watching

Sand is another heat storage alternative.
So it's not really a battery since batteries store the energy in electrochemical form. This just turns excess electricity into heat, which is then converted back to electricity inefficiently (see Carnot's Law). The best efficiency to return the energy is 70%, which is not bad for heat storage but a waste of high quality electricity used to produce it.
Sounds fake
Turbines never have a better effiency than 47% (and thats top)….. so basically you lose more than 50%…. What am I missing, thats not efficient.
Work out the efficiency of turbines and generators to make that energy into electricity, then compare efficiency with a Actual Lithium battery.
This is The ELECTRIC Viking after all, otherwise maybe do an issue on home heat energy storage.
Is it better than just hot sand?
Yawn.. (at the scientists, not at you)
gotten further than this just chugging weed and talking to AI.
Molten glass is the future of this form of energy.
it can work in thermal condensers, as a storage medium, as a high temp application for many industries and can even birth a new industry of 3d printing glass houses with molten glass.
The reason we would want to do such a thing is it is completely possible to redesign houses so that they themselves are actually thermal energy collectors, transforming sunlight into heat and speeding it away in integral tubes in the walls made for turning a house into a heat pump. Foamglass interior walls act as incredible insulation to add to this and the entire thing can just be re melted and recycled later.
No excuse for nuclear reactors.
It seems that there would be a lot of inefficiency turning the electricity into heat and then the heat back into electricity. I'd like to know some numbers on that. It does have the advantage of how long the storage lasts. It also is using a dangerous and difficult substance, and looks as if it would be very high maintenance.
The Citroën Berlingo powered by Venturi works called the First Electric used a ZEBRA molten-sodium storage battery. Ford, decades ago, made an electric car that used molten salt battery but I can't find anything on the Internet about it now. I was aware of it at the time. After years of Ford's research bringing it closer to production, it ended up leaking and catching fire, which was sensationalized in the press, prompting Ford to drop the project. The ZEBRA ("Zeolite Battery Research Africa") battery was first invented in 1985, specifically developed for electric vehicle applications. Earlier versions were developed by Tokyo Electric Power Co. (TEPCO) and NGK Insulators Ltd. beginning work on them in 1983.
It is inefficient.

What they don’t tell you is the amount of energy required to keep the salt molten defeats the purpose of energy storage.
All talk and no real facts or info.
Molten salt is not new.
This is very inefficient. Even the best methods of converting steam into electricity are only 30% efficient.
The heat stored needs to be used directly as heat, not converted back into electricity.
For every 100 watts you put in, you will at most only get 30 watts out.
I cannot believe heating salt to very high temperatures, storing it then using it to produce steam to drive a turbine is not incredibly inefficient. Is this yet another BS story to fleece investors and EVangelists. If it's been used for decades, it is not a new technology and clearly is not the answer.
Update your knowledge on molten salt as an energy storage, Sam…since it is being used for decades now…just like pressure.
This is not a battery…. Batteries store electrons that move at the speed of light. Not heat that to heat water to turn a generator then move electrons.
Battery storage is instant response. So this is thermal storage not battery storage. The both work though.
Might be a good way to store heat, but not for storing electricity such as generated using photovoltaic solar panels or wind turbines.
I previously watched a video report about something similar along this line about some project in China.
But I don't know if it's the same kind of thing.
If it is, then Denmark isn't the only country doing this. And don't know if it's even the first country.
When I was a young kid almost 50 years ago, I was interested in electricity. My father gave me his equipment, and I experimented with salt, water and electrodes of different types. I put water in a glas, put lots of salt into the water to enable current flow, and used a copper wire on one end and aluminum foil from the kitchen on the other. My goal was to produce hydrogen, which worked, but I discovered that my setup actually stored electricity. I had unintenionally created a salt battery, which I used then to power a few things to see ho much energy I could store.
Not knowing about future EVs, I ended experiments after a few days and completely forgot to file a patent 😊, and went on to do more interesting things. I also had schoolwork to do, see, I was 9 years old at the time.
May I make the suggestion to please use consistent units throughout. It's great you did the math, but it would be really edifying if you could collect all the numbers on one screen and go over them step by step for a visual comparison. This issue is all about the numbers. It's impossibly unwieldy remembering comparisons of prior costs relative to each other, current relative costs, prior and current comparisons of costs for both types. Units of MW, KW and W; units of MW/h, W/h; monetary units of $ and cents, and two multipliers of 4x and 7x. Build vs. production costs. Plus the consideration of inflation. I've been scrubbing the video back and forth for half an hour trying to recreate your math to verify, and I give up.
check out AMBRI and their liquid metal battery using a salt. MIT professor donald sadoway has been at this for over 20 yrs. it produces electricity directly from molten salt . it's not heat storage but electricity storage.
Efficient? If you are converting stored thermal energy back to electricity then you hit the wall at about 40%. No different to burning coal or gas in that respect. That is nowhere near as good as electricity stored in a real battery. I think the term "battery" is misleading in this video. The overall idea of the projects is fine, just that I think this report is inaccurate.
For heating it should be ok, but for energy generated -> stored as melted salt -> recovered energy (as electricity) -> delivered energy; there are losses (what percentage?). The maintenance of the facility is also not cheap (I presume) and the personnel operating the facility needs to be paid as well.
Not new. Not a battery. Does not store electrical energy, it stores heat. To deliver electricity heat is used to generate steam to drive turbines/generators. Totally different to Lithium batteries.
If this is more energy efficient then green hydrogen, why is Australia still pushing green hydrogen as a future energy commodity (especially for manufacturing).
We should be perfecting and manufacturing these batteries.
Hi Viking! Glad to see you talk about thermal storage technology. It's far cheaper than batteries and we have been doing it for 17 years here in China. Beside electricity human being has great demands for heat like hot water for space heating, steam/hot oil/ hot air for manufacturing. Most of these heat can be provided through thermal storage system. For our system we use off-peak electricity or abandoned wind or solar energy to heat up MgO bricks up to 750 degree C, then use is to produce hot air/water/oil or steam. We have a lot of projects in China and if we are lucky we will have a project in Denmark this year.
Makes sense to use a mature technology in a rapidly evolving energy storage environment!
👍🏾
My first homemade batteries for LED’s were Simple Salt Water Electrolyte. Copper and Zinc Electrodes.
Pretty disappointing video. No numbers provided – just a lot of hype. Lithium batteries return more than 90% of the electricity used to change them. Molten salt would return < 50%. Relative cost of storage would also prove helpful
I have heard of molten salt power stations like the one in Morocco. https://en.wikipedia.org/wiki/Ouarzazate_Solar_Power_Station
Notice he says the same thing over and over again just to make the video long? watch the first 30 seconds and you know everything.
The ideas are not new and have been used in the past. But look at the infrastructure need to use the battery! You have to build a power station to use it! Just sounds like a huge overhead before you are able to get anything from it. Then spinning turbines up and down every day will create a lot work on the system it self. Also molten hydroxide salts are extremely dangerous to the environment and personal. They are so corrosive they eat through glass and a lot of metals. These are the reason it is not used much if anyone is .
This sounds very inefficient. As described, PV electricity produces heat, which is stored. The heat is used to produce steam for a conventional thermal power plant.
If the molten salt battery system was cheaper than lithium, it might be a good idea. However Sam states it is slightly more expensive.
Ancient astronaut theorists say this technology was already used by Anunaki…so, it's at least 12,000 years old.
Molten salt batteries is not a new invention. The Think EV used a molten salt battery called the Zebra battery back in 2007. It was kind of unpractical since the temperature had to be kept above 270 deg C, and the energy density was around 120 Wh/kg. At that time this was about the same level as lithium batteries and far better the lead acid. But it was not very successful.
It's not the first one, this technology has been around for a long time.
