I just found what I think is a show stopper for the Ionic 5 and related. It's the wheels and tires. P255 45R20. Why choose super low reliability...
It's complicated but you don't need a lot of grid storage if you have a lot of dispatchable load. What you do need can be addressed by hydro,...
I was at the control room of my local utility and that's what they told me.. It addresses everything including thermal and transportation,...
I was simplifying but if you want a more detailed explanation, read this, written by my friend and coworker....
Pumped hydro is only around 50% efficient - better than hydrogen returned to the grid, but not by much. The advantage is that it's pretty cheap...
To point out that battery storage won't work and we will have to do something else - like dispatchable load.
Not exactly but that's not a bad way to think of it from an energy perspective. Another way is to realize liquid water is going to result in two...
Lower Heating Value/Higher Heating Value To convert water into hydrogen, you essentially have to add energy equivalent to converting water to...
That's right - it's co-production, but it's *controllable*, which converts variability into controllability. The best on-grid storage is no...
LHV = 33.3kWh/kg HHV = 39.4kWh/kg The best you can do it put in the HHV and get out the LHV: 33.3/39.4 = 84.5%. They must be ignoring the loss...
Since the theoretical limit is 84%, I'd like to know how they did their math.
CAES is only really viable if you combine it with natural gas. Hydrogen is much more efficient than CAES because YOU DON'T RETURN THE ENERGY TO...
None. But as variable generation replaces thermal generation, this issue will change from handling events to handling normal day to day and year...
I just found out a fact that puts "massive storage" into context. How much storage would have been required to avoid the Texas blackouts last...
Yes. However, 4 miles / kWh (the same as 25kWh/100 miles) is just an estimate. My long-term (nearly 4 years) average is 5 miles / kWh. Yours...
Amitron? Retro Thing: 1968: AMC's Amazing Amitron Electric Car [IMG]
It does look badass. Heavy on "bad" and heavy on "nice person". I think the styling is based on legos or something.
All pickup trucks are inherently ugly because they are half car, half trailer, welded together.
Bad assumption. Even worse. 80% of 250 vs 70% of 400. Hmmmm.... Why wouldn't you just do what we do now on our current lithium ion batteries...
LOL! I'm an EE specializing in power and I've owned high power batteries in quantity since 1986 - NiCd, NiMH, lithium polymer and lithium ion....
