Form Energy: An Overview

[@marckemper577]

Glad to this technology with headquarters in Western Pennsylvania, and future production in West Virginia. It’s a win-win for both states, and the USA.

As a seasoned mechanical engineer that has invested a lot of money in Tesla - I am praying that this technology can deliver as promised - we need as many storage solutions as possible- we need them all!

Rooting for you guys! 🎉

I was trying to find out how your technology worked, I assumed you'd be using a porous carbon cathode material like with lithium air, to store Fe oxidised ions, but it's really interesting to see that the oxygen is simply transported to the iron particles to rust in place. Very clever! A quick questions about the rust though, a common problem with rust is that it easily detaches from the surface, how do you stop this happening and stop the loss of active material?

Hope to hear more details soon. Will do a simulation with different storage systems.

That's the way to clean up the grid and go carbon-free without the use of nuclear power. Even as a supporter of nuclear power I say kudos and bring on these large grid-scale batteries... All forms of carbon-free power are wanted and needed ASAP!

what i don't understand is how come they just don't use iron air batteries for home storage. seems like the ideal situation for at least grid backup. even though they maybe only 50% efficient. buying grid power is cheap and iron air batteries cost only $2 to $5 per kwh, so a home system for say 1 megawatt hour should only cost a few thousand and should be able to power a home for a month or more without power in the event of a prolonged power outage.

Boy I have a lot of questions. I’ve had solar for a few years now, and I have seen the dramatic difference in the energy flux between June-July and December-January. To provide consistent grid-scale power throughout the year using solar alone, it seems to me you need to either overbuild solar with some fast batteries (like Megapacks) and use curtailment, or you need to have a storage solution that is long-term, affordable, and responsive. Form Energy sounds like a good potential long-term storage solution, assuming the costs are good, which I hope they are or you have no basis for your business. Is iron-air batteries responsive enough to handle peak loads like Li-Ion or is it best to provide consistent baseline power? Would the best solution be to have large Form Energy storage fronted by a Tesla Megapack (to handle peak demand) who are both tied to a large solar/wind farm to take advantage of seasonality?

100 hour storage is impressive but that is no solution for seasonal variation winter to summer, though it would certainly help the day/night and occasional cloudy day scenarios if you live off grid. Good luck.

There are these things called grid inter-connections. You do know it's very very rare for those dunkleflaute events to exist and when they do you can still prepare the grid by turning on backup power sources and or batteries until the sun shines and the wind blows again. Those gaps are RARELY more than 100 hours hence the battery design drain time... SMH... If we all listened to people like you we'd be living in ditches poking berries up our noses... FFS, man!@@chrisc62

I was waiting for this to spac but it never did
