Tesla Batteries for your HOME are 6 months away according to Elon Musk

[HenryBHough]

I gotta say there ARE homes that can be run totally off the grid. In locations where there are no powerlines. But each one has a small room full of wet cell batteries. Glass jars full of acid. I've seen 'em with even electric clothes dryers and heat lamps for small bathrooms.

But I've also seen 'em with those battery rooms barricaded to keep children from playing in there and dissolving themselves.

 

[Old Rocks]

An electric furnace does not care where the mega-watts of power it uses comes from. And you would not be using those batteries to run the furnace continually, but, rather, to finish a heat if the power were suddenly interrupted. More important, it would allow industries to power down softly in the case of an extended outage.

If you have a large home battery, say 100 kw/hrs, no problem at all to charge it. First, if you are grid parrallel, then you can charge it off the grid, second, if you have solar of 5 kw, then you probably will have an excess of power each day top the battery off with.

No fucking way would a battery work in this situation.
That you think a battery is going to enable you to use 12500 kw is total bullshit.
And even if you wanted to use it to "to let it down easy" the cost would be prohibitive. You'd be better served with a generator.
And you said a home could be run "off the grid" again total bullshit.
If that were the case they'd already be using a system like that.

They won’t be for sale, however -- not exactly. Instead, the company plans to package them up into its 2-megawatt, 1 megawatt-hour GridBank containerized energy storage systems and make them available as a turnkey contractor and ongoing operator of energy storage sites and farms, he said. That could be as contractors of government or private utilities, or as market participants, he added.

There are 160 units of 12,500 kw in 2 mw. And the battery serves to isolate the installation from 'bumps' on the line that routinely de-program PLC's, and cause loss of product and very expensive downtime.

There are many homes at present with off the grid systems, and they are for sale as a kit. Just one source;

Wow. Haven't seen anyone referance those types of batteries in ages. Museum peices.

Listen Up Home Solar Battery Storage Systems Are Coming

Great progress is being made with more compact, cost effective and efficient battery storage systems. These systems use lithium ion batteries because they are lighter (wall-mountable) and capable of many more charge-discharge cycles. Although still more expensive than lead acid batteries, volume manufacturing for the electric vehicle industry is spurring significant price reductions. In addition to new battery technology, these home storage systems also employ advanced electronics and software control systems to further reduce costs and increase functionality.

To many solar old-timers, the battery storage industry resembles the rooftop solar industry about 15 years ago. The demand is apparent, the technology is rapidly improving, costs are coming down and incentives are in place to help jumpstart adoption. One of the new companies targeting this market is JuiceBox — a Silicon Valley startup that is developing a lithium-ion battery system that will maximize intermittent wind and solar energy generation. Please listen to this week's Energy Show on Renewable Energy World as Neil Maguire, JuiceBox's CEO, describes their system of batteries, electronics and control software.

An Electric Furnace may not care, but the Electrician who replaces it because its damaged does.
Can you make steel without Coal?
Without Natural Gas?

An Electric Furnace? What are you talking about Old Crock? You definitely are over your head on this one. You can not be so dumb that you would suggest you can use a battery to make steel.

Yes, Elekta, old gal, electric steel furnace;

Electric Arc Furnace Steelmaking


Rendering of exterior and interior of an electric arc furnace.
An electric arc furnace (EAF) is a furnace that heats charged material by means of anelectric arc.

Industrial arc furnaces range in size from small units of approximately one ton capacity (used in foundries for producing cast iron products) up to about 400 ton units used for secondary steelmaking. Arc furnaces used in research laboratories and by dentists may have a capacity of only a few dozen grams. Industrial electric arc furnace temperatures can be up to 1,800 °C (3,272 °F), while laboratory units can exceed 3,000 °C (5,432 °F). Arc furnaces differ from induction furnaces in that the charge material is directly exposed to an electric arc, and the current in the furnace terminals passes through the charged material.

Old Crock, your cut/paste was of the wrong section, to make your claim you need to know the energy requirements of the furnace, that is measured in MVA, not temperature. Still think a battery could supply millions of amperes of current for a long enough duration to make steel?

If so you should link to something other than an EAF, these do not make steel, they recycle steel already made, huge difference in the amount of energy needed.

Old Crock, you said you worked making steel, you must be a "filthy" liar, I do not even need to link to prove that Old Crock, you did for me. IDIOT!

Electric arc furnace - Wikipedia the free encyclopedia

Although steelmaking arc furnaces generally use scrap steel as their primary feedstock, if hot metal from a blast furnace or direct-reduced iron is available economically, these can also be used as furnace feed. As EAFs require large quantities of electrical power, many companies schedule their operations to take advantage of off peak electricity pricing.

To produce a ton of steel in an electric arc furnace requires approximately 400 kilowatt-hours per short ton or about 440 kWh per metric tonne; the theoretical minimum amount of energy required to melt a tonne of scrap steel is 300 kWh (melting point 1520°C/2768°F). Therefore, a 300-tonne, 300 MVA EAF will require approximately 132 MWh of energy to melt the steel, and a "power-on time" (the time that steel is being melted with an arc) of approximately 37 minutes. Electric arc steelmaking is only economical where there is plentiful electricity, with a well-developed electrical grid. In many locations, mills operate during off-peak hours when utilities have surplus power generating capacity and the price of electricity is less.

Battery storage is the key to alternative energy, and mitigating what is called the 'duck curve'. Obviously, solar only generates during the day. There's so much solar here that grid demand from utilities plummets during the day, and then rises steeply in the late afternoon and evening. The curve looks like the underbelly of a duck.

Natural gas peaker plants are fired up to supply power in the late afternoon and early evening when demand is highest. For businesses especially, extra demand charges are levied during high demand times. A hotel's power bill can be doubled by what are essentially penalties.

There's a new Silicon Valley start-up called STEM. They make massive batteries. The Mark Hopkins Hotel in SF just bought two STEM batteries, and they don't even have any solar modules or turbines. They get a return on investment simply by charging the batteries during off-peak hours and running off the batteries during times of high demand charges. Return on investment could be as little as 3 years.

Hawaii is the true testing ground for battery storage of solar and wind power. Each island is essentially a micro-grid. It's expensive to ship gas and oil out there. But, people use power at night, and when winds are calm, so battery storage is needed to go renewable.

Batteries are essential to achieving total defection from utilities. Up here in Humboldt County, many people have lived off the grid since the 1970s, using solar, wind and Pelton wheels. But, the battery tech has always been rudimentary (deep-cycle RV and even golf cart batteries). Tesla is creating the next generation of lithium-ion battery storage for homeowners, and their new gigaplant will be able to recycle old batteries.

10 years ago people like you were making fun of the idea of EV's as little golf carts that would never be able to use the freeways. Then came the Tesla, blowing away muscle cars in a large luxury sedan. Those magic batteries will be on the market in less time than that.

I believe the instructions are, you keep quiet, bury them, cry at the cost of new ones, and hail it as a success whilst claiming those that don't get them are stupid.

Well, here we are, 11 years later, and Evraz of Pueble, Colorado is running a steel mill and arc furnaces with solar and battery backup. LOL You Luddites don't know much about how technology works.

Longtime Pueblo mill makes move to solar power to make world’s “greenest steel”

A steel mill in Pueblo that has been powered by coal during most of its roughly 140-year existence will now get most of its electricity from solar energy.

You are truly a fucking idiot. Were those batteries natural, they would be considered high grade ore for the metals contained in them. There are already companies making a profit recycling them for the metals in them.

God I love these old threads. They show just how truly stupid the luddites here are. Yes, we have affordable home scale batteries now from Tesla and other battery suppliers. We have grid scale batteries up to 500 MW/hr being constructed as we post. And only a decade after you posted you ignorance.
