Just sharing some interesting startups. This is driven by my realization that Tesla energy has just failed to scale and that the market has emerged (solar and wind) and they'll be unable to meet it. I was curious and started looking for companies other than Tesla providing solutions.
First I read about Fluence. That took me deeper into battery startups and I Realized that Gates vc firm has invested in at least 4 battery firms, quantumscape, ESS, Form Energy, and Our Next Energy (ONE). ONE was featured in a Sandy Munro video earlier this year (or last) and is led by A123 alum. Back in the day I thought A123 had promise. They seem to think that they'll make it this time and supposedly have a client. Unlike the others it is pretty simple- Lithium iron phosphate with a twist to help reduce costs and increase range. We'll see, supposed to be shipping to first client now.
How will they compete with the likes of SES (backed by several OEMs)? no idea..just lots of neat ideas out there besides the 4680.
Quantumscape is a bit famous- solid state batteries. Also featured on Munro Live. Lots of promise in solid state batteries but right now they are still just pencil eraser tiny. Huge publicity...big firm...no product yet. If they ever commercialize it is the end of the game or many competitors.
ESS and Form are both targeting industrial and commercial scale energy with Iron - salt water (ESS) and Iron air (Form). ESS is doing something others have tried before, there was a PA based startup several years ago that tried and failed to scale with saltwater based batteries. ESS is packaging in a shipping container sized offering that scales and supports multiple containers. Bunch of saltwater and iron so you know it's going to be heavy. I have some questions on energy storage on their solution but it's interesting and non toxic.
Form is interesting and seems pretty clearly set on a path to commercial success. Bit more energy/sq meter of space. No products yet. Again, iron and air? Both these companies are thinking (is what I think). They have solutions for the giant raft of solar farms and wind farms. Lower costs than the iron phosphate solutions, they just need to get the first few sales and have them running a year or two.
Then I kept reading and learned about Rondo Energy (gates backed as well so 5)- really neat solution using Iron & bricks (yep) and is focused on energy/heat needs of industrial entities. How cool is that? Most big industrial processes are giant consumers of heat (cracking in a distillation chamber, cement, metals smelting, making good pizza (checking if you are skimming), etc. Very much a company to watch and I wish them every success.
All backed by Bill Gates firm. Used to be the kiss of death for his firm to invest in your energy startup. Now...now the firm looks brilliant with 5 well regarded startups and only 1 needing to really make it for them to have a giant homerun. Frankly I don't see why they can't all be successful.
Companies like Fluence will be buyers if the utility/energy ones can get any traction.
Then there are companies like Amprius that are focused on niche markets- aviation in this case.
