Separate names with a comma.
Oh, I thought QuantumScape was 20 years ahead of everyone. You're forgetting their nearly 2x energy advantage, meaning the same charging rate...
You got any other 400 or 500kWh/kg batteries?
You must be very naïve not to trust a US-based, Brookhaven National Lab origin company whose products have already been used by Airbus Defense and...
There's no evidence to support your unsubstantiated opinions, therefore they might as well be written on used toilet paper.
I think you've entirely missed the point - the Sion battery isn't considered "solid state". It's close to solid state, using a ceramic-polymer...
You must be a shill or a stock holder or something to be this irrationally exuberant.
QuantumScape's opinion of their competition is not particularly interesting or credible since these batteries both exist and have been tested. If...
Wind is actually pretty great on Hawaii because of the trade winds.
The same as you said here: That's because Texas' electricity market is as dumb as a sack of hammers. 6x average Multiply by 6 or so. On...
No, it doesn't. It doesn't mean that either. Then you've got nowhere near enough long-term storage. Well, maybe in Hawaii where the...
I doubt many people will tolerate the idea of having to handle high-level or low-level nuclear waste from a new nuclear powerplant, especially on...
I was at a wind farm on Oahu (North shore). I was on top of the Mod 5 turbine there and two of the turbines I work on at work came from there....
There are a ton of construction activities at locations that don't have a grid. For example, building a collection system for a wind farm. There...
Hawaii is unique (and not monolithic - the islands are all unique). It may make a tiny bit of sense there but Hawaii's issue is that they don't...
Over-building of the source. The idea is you build the source for the worst time of year and the rest of the time you use the excess to make...
HHV for Hydrogen is around 39.4kWh/kg (from memory). If your electrolyzer is 100% efficient, that's what you'll need to put in to get hydrogen...
Yeah, I don't buy it (and I work at NREL, and have also published studies on this). The reason is, the cost of the storage is around 3x the cost...
Hydrogen is not a good choice for storing grid energy and returning it to the grid. Batteries and curtailment are better. Hydrogen is only a...
Nope. That's just not true. Generally residential panels range from around 100W to around 500W each, depending on manufacturer and model, though...
It's self-pressurized and room-temperature, and you have to realize that 70% of 400Wh/kg is a lot more than 80% of 300Wh/kg, plus if they ran it...
