Do you complain when you have to refuel your car before reaching your destination? Maybe you find it inconvenient to eat more than once a week. Batteries have come a long way, but can't keep up with the demands and wants of the people. I've had this discussion several times.
Whole-heartedly agree. Too bad we can't change human behavior. Everyone wants more, bigger/smaller, and faster and they want it yesterday. Nevermind the fact we don't need or use it. And I include myself in that behavior as well.
I'm far from a battery expert, but my belief is that the substances known to be suitable to build a battery simply don't have the capacity to develop electrical energy for truly long periods. Think of what is required - regardless of whether we're talking energy storage for wind, or solar, you'd better be able to provide a clean 7-days' worth of electrical energy at advertised output, and those substances simply don't exist currently.
Researchers in Germany are currently working on a battery which shows promise, but a practical prototype is still a few years away. I don't believe that there's a, "conspiricy theory" at work, because the first one to, "reach the finish line" stands to make a big pile of jack. Once the final barriers are broken, among other things, you'll see a subsequent, rapid de-centralization of electrical energy generation, because consumers will embrace these technologies.
I've checked into doing something for my family, and truthfully, I need to come up with at least $25,000.00 - $30,000.00 to generate a scant 12-KW reliably. Payback is well-past 25-years, so guess what? I'm reluctantly sticking with the electrical energy utility in our area.
What's the big deal? Spoken like someone who doesn't have to do it.
Facts are we have improved batteries by a factor of 4 but no matter how good they are, everyone wants more for less in a smaller size. Then they bitch when given bleeding edge tech and the laptop bursts into flames!
Maybe consumers could stop wanting all those features they never use, maybe a slower cpu or a car that does take 4000lbs to move a 200lb person around?
And back on topic, we already have $100/kwhr batteries for grid UPS work. They are called lead batteries. Yet no grid battery banks of them. Why? Lead in grid UPS use costs under $10/kwhr/yr.
Could it be there is no market for batteries in that service?
Grid storage other than very short term like under 5 minutes peaking isn't a problem at all. Why is the grid has been doing that, adjusting the grid since it began around 1900.
Facts are grid demand is far more variable than RE and supply and demand are really just 2 sides of the same coin. So No, you don't need more than 2% of grid storage and that is just for smoothing out the second to second difference between supply and demand.
Though that will easily be solved by the smart grid along with home, apt and EV batteries, charging when cheap to absorb extra grid power at night and between daytime peaks while supplying power during peaks. The utility saves so much in peak power costs and added revenue at off peak EV's might get free fuel for their service.
Recent CCGT tech can be throttled up to 50% power using NG also will cut the need for grid storage.
Another Solar thermal panels are used to suppliment NG power plants meaning no storage needed. Biomass, Hydro also are on demand. Really the only problems are big distant wind farms that start/stop together and even their with cogen biomass to cover when the wind isn't blowing.
And last for now, far more RE spread out in small systems on many homes, buildings will average out very well again making storage far less.
This whole scam was made up by big energy/power because they know RE is already if well shopped in many places competitive with coal even before the 30k people/yr in the US that die, etc. from it's pollution. And they want the corporate welfare to continue paying congress to make sure it happens.
The question of whether engineers could have foreseen the shortcut maintenance procedures that led to the crash of American Airlines Flight 191 in 1979 will probably linger for as long as there is an engineering profession.
More than 35 years later, the post-mortem on one of the country’s worst engineering disasters appears to be simple. A contractor asked for a change in an original design. The change was approved by engineers, later resulting in a mammoth structural collapse that killed 114 people and injured 216 more.
If you’re an embedded systems engineer whose analog capabilities are getting a little bit rusty, then you’ll want to take note of an upcoming Design News Continuing Education Center class, “Analog Design for the Digital World,” running Monday, Nov. 17 through Friday, Nov. 21.
