Great reporting. Dave, my take is that an immediate need is affordable home storage batteries. Affordable ($10,00), 50 kWh home batteries would allow most homeowners to cut the bindings of the corrupt electric cartels and go off grid. And, home energy independence would be the gateway drug for the switch to electric home heating and cooling, electric cars, etc.

[@ricos1497]

Great! Until the electric cartel becomes the battery cartel. What's the difference in paying 100 per month for electric, versus paying 10,000 for a battery every 10 years? We've been through all this before, the electricity companies simply happen to be the current monopliser of the day. As soon as we switch to an alternative, the "free market" circles around and monoplises the next technology and our human needs are then sold back to us by a different company (often with the same shareholders). The market will serve us an illusion of choice, hiding the real piture of a handful of companies owning all the tech, materials etc. It occurs in every single area of human need, whether it's our shelter, energy, food, water or whatever, it's either a company or a state monopoly. There is no independence from this system, without completely shunning it in all its material glory (a wood stove in a tiny house or such like).

I agree that for stationary storage, iron-air looks like a good idea. The technology seems to be safe enough that it could be widely distributed so that the grid only needs to supply the average power consumption rather than the peak.

You're right Tom. I've done a previous video on Form Energy, and I probably should have mentioned them, even though iron-air does not feature in the Fraunhofer report.

@@GTN3 There is a lot of talk about power grid system inertia, which is the ability to maintain a steady grid frequency. At this time that inertia comes in the form of the mechanical spinning of turbines. It sounds to me like a justification for the existence big power plants. Maybe so, but with a distributed network of batteries maybe less grid inertia could be possible. Also,, from what I have seen, about half of the electricity produced by a centralized system is overhead. Distributed generation would be able to handle the new transportation infrastructure needs.

[@chrisconklin2981]

@@skierpage Yes I am talking in general terms. Ultimately we are talking about two different power systems. The present old model is a system of large central power stations that are interconnected. As electricity is an instantaneously generated commodity, load balancing is critical. To accomplish this, standby generating capacity is unused overhead. As a paridimial shift to a new model, batteries will be important because they are "time buffers". In a distributed generation system instantaneous frequency modulation can be pushed down to the use level. No longer will centralized power grids be required to balance load frequencies or provide backup. It is not yet proven that a distributed system can supply long term needs. So it remains an issue. To be fair unused battery capacity could be considered overhead.

Somewhat I think, what happened for solar, in terms of price drops, will happen for batteries (this decade). There was a time people talked about thin film CIGS as the solution to cheap solar. Remember that? But it turns out, good ole silicon still turned out to be the dominant technology. Maybe due to scale of manufacturing. Accumulated experience. Similarly, I think the same will happen for good ole lithium. (Maybe sodium has a chance also.). The demonstration (at scale), would come from the likes of BYD and CATL. This is with manufacturing issues solved, and deployment at scale. Lithium will still be, by far, the mainstream. Better ways of mining, refining, and recycling will be developed. We'll get better at dealing with lithium, and scaling up. The alternative chemistries may have a chance. They may have a niche for specialized use cases, such as high energy density, e.g. eVTOL's. Or long duration storage (e.g. iron air batteries).

[@kensmith5694]

It's great to see so many options popping up when it comes to battery tech, and I don't think it will be a matter of the best that will win out but more about the tech that's good enough and can be manufactured cheaply enough and on mass, especially depending on use case. For home or grid energy storage, size and weight isn't as important, whereas price and how much energy can be stored is, whereas for portable tech devices or EV cars, weight and density is important, you want more energy in a smaller, lighter and more compact package. So honestly, I think we'll end up with many solutions when it comes to energy storage which the key driving force will be how easy it is to manufacture and how cheap it is to buy that will likely win out, in other words, not the best tech if it cost an arm and a leg. Still, we've been waiting for this holy grail of battery tech for so long that I wonder how much longer do we have to wait, but on the plus side, thanks to renewable energy and EV cars, there are a lot of ideas being experimented on when it comes to energy storage, as well as resources thrown at it, so it's only a matter of time and will probably happen much sooner because of the big push to renewables and EV cars taking off.

Batteries V's Pumped hydro. It would be good to know how many Kwh each technology has ? I find it hard to believe batteries are as large. I agree they are trending above in installed capacity. Another great "Just Have A Think" Thankyou.

Invinity are doing great things with Vanadium flow batteries. As said here, they are for stationary storage.
