www.ted.com What's the key to using alternative energy, like solar and wind? Storage -- so we can have power on tap even when the sun's not out and the wind's not blowing. In this accessible, inspiring talk, Donald Sadoway takes to the blackboard to show us the future of large-scale batteries that store renewable energy. As he says: "We need to think about the problem differently. We need to think big. We need to think cheap."

I have been following this video for more than 5 years now. It is a total of 8 years since this Ted talk. Where are the batteries? A press release and a fancy website does not count.

Reviewed many low CO2 emission motivated startup efforts in the last 10-20 years in battery, fission, and fusion. Pretty much all dead end with each eating $50M+ investment. In hindsight, the low CO2 mission statement is actually source of the problem. Repeatedly causing people to make wrong decisions instead of all the capitalism actions required to keep operation moving forward (like getting customers sooner rather than later). No-little sales results in limping on science grants and philanthropy before closing doors and stopping iterative refinement on technology. In reality, the biggest CO2 reduction technology has been Natural Gas. US source it cheaply and domestically through huge fracking expansion is the key US CO2 reduction driver. Japan needs to get it shipped in via liquid (LNG). Germany gets it from Russia vis pipelines (1 now, 2 soon) Biggest lesson learned : Low CO2 emission mission statement is okay as a starting point. But need to shed it quickly and avoid using it as a main argument to make decisions continuously. Otherwise, countless wrong economic decisions will be made and company will die.

As a comparison Indonesia's current 3.5GWe contract for the seven x 500MWe Liquid Thorium ion molten salt ThorCon "energy converters" have "As-built" foot prints of 1.1 Ha (65m x 175m) for each 500MWe unit. These will provide High temperature automatically load dependent output at near atmospheric pressure under extremely "walk-away safe" conditions at a capital levelised output cost of less than US$0.04/kWh as well as having the capability of doing a cold/black start. So with a 44kW/m2 footprint it is going to be hard to beat by any combination of renewables and battery banks providing 52x7x24 electricity... ruvid.net/video/video-qd_lBPbeVrQ.html

I say ask high school kids and college to find answer for our energy...new minds. We need to hurry. Ask anyone. Many men play in their garages. Also ask them. Lots of brains in places where inventors just do life. They need to be encouraged instead of expected to be highly educated.

8 years later... Still no liquid metal battery. What's wrong with using excess energy to raise a weight so that you have stored potential energy?I have heard that we already pump water up to a tank so that it can be released through a dynamo at a later date.

6:26 I like your concept of liquid salt, however I would use a thorium molten salt reactor to produce electricity. Only because that, there would be byproducts, that would be more valuable. Molybdenum 99 for cancer therapies and cancer research, xenon for interstellar space travel, excess heat for water desalinization, etc. your plan produces none of these byproducts. Build a model, too many moving parts, in concept to production. The field application is brilliant. However, for mass consumption, mass generation is workable. In my model you just have thorium reactors on a grid, the grid sends power to where it is necessary. In your model mining, manufacturing, and distribution of your batteries is too many moving parts. Military and government applications, need your battery.

You know when you look on youtube and the internet you will find a lot of amazing stuff like this. With all of the demand for such technology and our constantly increasing energy needs you would think they would find a way to use this technology and start mass producing an actual battery. The date of this video is march 26 2012 it is now november 2020. OK when are they going to get started already. You are constantly hearing about new technology like this everyday, why does it take sooooooo maaaaaany years for the technology to be applied to anything.

There are several problems with solar energy: 1. It takes lots of energy and materials to produce, mount/erect and maintain a solar farm 2. It requires lots of land space for large scale capacity power generation 3. What do we do with the materials after the life expectancy of the panels have been realize? 4. The underlying impact on wildlife. 5. You will need LOTS of polluting batteries to store energy for re-use at peak time when the sun is down...

.......excited about his baby but I don't have the heart to tell him sodium sulphur fits his criteria much better..Antimony of all things is not so abundant..He does mention other metal combinations but sodium sulphur still sounding better. His battery needs the top molten metal to be lighter than molten salt and the bottom metal or element to be heavier of course. Positive terminal which is actually called cathode for batteries needs to be a metal or element for which it's ions easily migrate through the molten salt. Looks like it's fun to play with.

Nice for the grid-level storage! However there is the fundamental problem with renewables: they dont scale in size and price as in the case of his design (dirty cheap and container size) battery. Search fro energy-density. However, we can down scale atomic energy. The possibility to change output form atomic is something I cannot vouch fpr, but my understanding is that he is incorrect. Currently atomic is the buffer renewables require on a grid level, exactly because they reliably can respond to difference in demand.

OMG! Somebody who understands the pivotal gap. However, batteries are the least desirable way of doing storage. Unlike systems like pumped storage, we pay by the watt-hour rather than by the watt.
David Davids
David Davids 4 months ago
it is not clear whether you understand that pumped-storage energy costs More to produce. the economy of the system derives from the ability to consume power to run the pumps, during 'off-peak'. then, sell power during peak demand. en.wikipedia.org/wiki/Pumped-storage_hydroelectricity

Another "fantastic" idea. Just like Elon's fast trains in vacuum tunnels and electric tracks. Problems? Yeah, the science and the laws of nature:-) Now that we have abundance of that "theoretical" electricity we need only devices that will run on it. But these are another invention we currently working on........... Anybody want to invest in this future?

Electrical batteries is very old school. Today we are creating plasma capacitor batteries. No moving parts, scalable, room temperature and under normal atmospheric pressure. Results are very encouraging since by comparison whatsoever load is placed upon these battery/capacitors and their superconductive , semi-conductive properties lend to leading, even disruptive battery technologies that will eventually replace voltaics.

Alexander Biersack

People who don't do the math are bound to talk nonsense and he did not do the math how much energy we really need to store and what it would cost. Others have. With the facts we now know from Germany it would take 180 billion to provide enough storage to replace just 3 coal or nuclear power plants. But we don't need to replace 3 we need 3500 power plants to make the EU CO2-free and another 3500 to make the US CO2 free and a similar number to do that for China or other places. To make society CO2-free we will need to replace a lot that is done with oil and gas today by electricity, we will need a lot more electricity to do all heating and everything we can with electricity instead of fossil fuels. Not a little, a lot. So even if he brings the cost down to 1/10th of what it is today, it would still be 21 trillion for the US, 21 trillion for the EU etc. People who don't understand numbers and don't know what the difference between a billion and a trillion and ten trillion is may think so what, but this is not so what, no society can do it. It is simply not possible with the means we have today. But what we can do is replace coal by nuclear and the price for the electricity will be approximately the same, this is something we could to if CO2 matters. Stop listening to your heart and start listening to hard cold facts. Emotions are nice but in this case you will have to put them aside and be rational.

Climate change is happening very slowly., If we survive that long it will be a problem eventually. Our best answer is technological & economical development.. Short of all out war GHG pollution cannot be stopped without advanced techniques. There is energy technologies that allow us collect solar power and beam it too the earth, There is fuel for pollution free, radio active free fusion power in large quantities on the Moon. There is means to scrub CO2 from the atmosphere but must be developed. The answer is to progress as fast as we can science/technology.
