Any method of power storage has to be cost effective, because it is competing against other forms of power storage such as pumped storage.

 

 

 

The fact that storage systems compete against each other is beside the point.

No storage system needs to be cost effective (relative to fossil fuel energy) if it is an accessory to renewable energy because renewable energy does not need to cost effective.  This is because renewable energy proponents have set the terms of renewable energy conversion as being that the cost of fossil fuel energy is infinitely high.

 

 

 

 

I can't conceive how that could be beside the point.  Supply/demand & competition.  Sounds like a good mix to me.

      Don't you suppose there has been a need for peak demand electricity since before we had renewable energy?  Our town had an atomic power plant built in the 1950's for use during peak demand.

When I talk about supply and demand, I am not referring to the supply and demand related to the storage of electricity for future demand.  Instead, I am referring to supply and demand in the cost/benefit analysis showing what the customer is willing to pay for the benefit of a product.    

Both fossil fuel and renewable sources need backup or peaking power.  Fossil fuel sources need backup for fluctuation in demand.  Renewable source need backup for the same fluctuation in demand.  However, renewable sources also need backup for their inherent inability to provide a constant supply.  So the need for backup power is fundamentally higher with renewable energy than it is with fossil fuel energy.   

This is a major difference between the two sources.  Basically both wind and solar require storage unless the users accept the interruption of power during the night and times of no wind; and also in times of unusually high demand. 

An alternative to storage for renewable energy would be peaking with fossil fuels, but this is not deemed acceptable because the use of fossil fuel is not acceptable. 

But the larger point in terms of supply/demand, cost effectiveness is this:  In a free market solution, a cost/benefit consideration is made based on what the market is willing to pay for the benefit.  Over the last century, coal fired plants provided power at a price that consumers accepted. 

But there was a downside that was not readily accounted for in the cost side.  Drawbacks such as mine accidents, black lung disease, and air pollution are external costs to coal that are outside of the direct relationship of the consumers’ price for electricity.  Detractors of coal consumption said that the true cost of coal has to include these so called, “externalities” or relatively hidden costs to coal combustion.

So the industry responded with cleaning up the pollution, improving mine safety, etc.  Then suddenly, the coal opposition claimed to find and prove a new problem with coal combustion that, for practical purposes, is unsolvable.  They found a new component of coal pollution.  They also found a new consequence of this new pollution, and the consequence is so dire that it must be avoided, no matter what the cost.  The new component of pollution is CO2, and the new consequence is manmade climate change.  There is no possible compromise with this unprecedented peril other than complete elimination of the use of fossil fuels.  Then the only alternative is renewable energy.

So now, the cost/benefit analysis of renewable energy gifts its promoters with the advantage of no limit on the cost side of the cost/benefit analysis.  The rail borne storage solution is an essential part of renewable energy, so it too is unconstrained by cost consideration.

I may be way off in left field here, but there are two definitions of political speech and neither is very complimentary. 

Rather than "political speech" as such, I interpreted the comment to mean "a political speech," as in writing the same.  

Most contain ambiguous statements, presented in a way that allows the listener to interpret them as they will, but hopefully as being complimentary to the speaker...

Euclid,

 

Once again, an idea that uses rail is pooh-poohed by the denizens of a railFAN web-site.  Maybe I am confused on the definition of a fan.  I think an operation like this would be interesting.  The doom and gloom GW crowd gets help when the wind dies down and I get a railroad to observe.

 

  Not sure if I fit the mold of who you're speaking of here.  I find the concept interesting.  It appears to be the railroad version of what has been done for a long time with pumped water.  The part I'm having trouble visualizing is could this be built for the $55 million mentioned, and could it be run at a profit?  As I read through the links and information, a lot of it reminds me of reading a prospectus for stock in some company.  Those usually have some terms that suggest that  "a fair amount of expected good fortune and wishful thinking were utilized by the writer, your mileage may vary".

     It has been interesting to learn more about this project and the system.  In my idle time, I've dreamt up a scheme to run a pipeline from the Pacific Ocean east over the mountains.  The sea water would then flow as a salty river into a desert area until it all evaporates into the atmosphere.  The evaporated water would eventually fall as rain in the desert.

      I now can see that the river can be used to provide peak need hydroelectric power and recover perhaps 85% of the cost to pump the water up the hill.

      So in one fell swoop, I will have lowered the ocean level, provided peak electrical needs to prevent the building of more fossil fuel power plants, provided jobs, brightened the desert flowers and saved the earth.  There's probably a few small details to yet be worked out.Stick out tongue

Something still somewhat unlear in my mind- is the locomotive that rides down the hill producing the juice the same type of locomotive used to take the weighted cars back up the hill?

That's how I interpret it.  This would be little different from the Milwaukee (and other electric lines) using regenerative braking - putting power back into the catenary on the downhill which is then used by identical locomotives climbing the hill on the other side.

Or, think dynamic braking, except instead of sending the power generated to resistance grids on the locomotive, it is put back out onto the grid.

While it's possible they would use conventional locomotives as a basis on which to build, unless they left the Diesels there as a backup (a la FL9's), the space where the prime mover and generator (alternator) sit could be filled by ballast and/or power handling equipment.

As I understand it, each railcar carries a weight.  At least some of them, if not all, are powered.  There is no separate locomotive per se.  The railcars that are powered are said to intend to use stock locomotive power trucks.  I assume the rest of the car, which is essentially a flatcar, is custom built for the task.  I also assume that only the powered cars will be able to also generate electricity on the downhill run. However, the weight carried on the non-powered, non-generating cars will contribute its energy by being coupled to the powered/generating cars.

I also read that the electricity for this system is handled through rail contact, as opposed to a catenary. 

Would this system be regulated as railroad?  Or would it just be regarded as plant machinery?

I think what Zugman meant was that is the best doublespeak you've done in a long time. 69 words that essentially say nothing because they simply go in a circle. Yep, you'd make a good political speech writer. Smile

Our town had an atomic power plant built in the 1950's for use during peak demand.

I doubt that your nuclear plant was built as a peaking plant. All those that I am aware of are operated as base load, which is the environmental and economic reasons for that mode of operation. For physical reasons, nuclear plants don't like to have variations in their load. And since their fuel is being consumed with time, the cost is lowest if they run at rated output. Also, as the initial investment is greater than any other type of generating plant, the ecomomics require maximum output to recover the investment. Remember that the cost of generation is return on investment, plus maintenance, plus cost of fuel. In the case of a storage plant, hydro, rail, or battery, the fuel cost is the difference between what the off peak electric rate and the peak electric rate. As said in a movie, "SHOW ME THE MONEY"

Let me rephrase that perhaps.  The story that is told, is that it was built in the 50's as some sort of demonstrator type project, to explore the feasibility of small scale nuclear power plants.  Remember, back then it was assumed that nuclear was going to be the cat's meow in the future.  I truly don't know if it was ever operational. 

      When I moved to town in 1984 it had been dormant for decades.  About 10 years ago, it was all torn down.  At that time, it was said that since it's inception, the plant had only been used to provide peak power.

     Now, how much of that is true, semi-true, or true-ish, I can't say.  Perhaps euclid could put a polished spin on that to make less sense. (Sorry man. the Devil made me do it.)

With a background of teaching High School physics, the stored energy by train was attention grabbing. Without reading the total thread I conjured up all kinds of data and thoughts. Before posting I read the whole thread. Nothing to add to the comments made by several BUT Norm48327 on Saturday, May 07, 2016 4:26 PM…. is just about my “color” also …… since everyone wants to add their two cents, let me add my NICKEL ! Some things to think about: when the man who discovered coal was first trying to sell the item from a wheelbarrow……no one gave it much thought. My, my how that changed. It seems when Rockefeller started refining oil to make lamp oil which replaced whale oil, he had this by-product that was a nuisance, nowadays known as gasoline. To say this idea of storing energy via trains on a mountain top, might seem foolish, this too might be premature. Conventional wisdom as shown by the comments made thus far would say, concrete blocks, mountain top, dynamic braked loco …. is foolish. ‘Course we are thinking within the box, not outside ! With the area considered being a very inhospitable environment maybe this unconventional approach will be a surprise When researching what is at play in use of water I found: Downside of PSH Power Saving Hydrology Wiki. ….. Typically, the round-trip energy efficiency of PSH varies in practice between 70% and 80%, with some claiming up to 87%. The main disadvantage of PHS is the specialist nature of the site required, needing both geographical height and water availability……. potentially in areas of outstanding natural beauty, and therefore there are also social and ecological issues to overcome. Then there is the famous Bay of Fundy hydro set up. Now this is nice, natural and a smart investment with a forever “source”. As you see the gravitational couple of earth/moon causes high/low tides. When high tide occurs the water “caught” in the bay is trapped by a dam w/generators embedded. Tide goes down and the trapped water can be used for peak power needs. This is super simplified in description as the peak and low tide will not always be at convenient times. They have a system of pump back when low tide occurs to get the water “caught” again in ready for a need. This is all possible due to the huge low/high differential unique to the region. Normal, 55 foot difference with the record being 71 feet. Then there is the post Posted by AnthonyV on Sunday, May 08, 2016 5:09 PM tdmidget : The problem is that it is impossible. To deliver the claimed 668 MW ALL 140 trains have to be in downhill motion at the same time producing almost 7000 HP each. IF that could happen, (and it can't) you would only have that power for 19 minutes. A farce and a way to scam the Government, which is us, out of a fortune. Can you say "Solyndra"? AnthonyV: The numbers as presented in the video don't seem to add up. In order to deliver 668 MW, 280 trains would be needed. One hundred forty loaded trains would be decending while 140 unloaded trains are ascending. At the rate of 560 blocks every 20 minutes or so, the 11,400 blocks would be exhausted in just under 7 hours. This does not include the time needed to load and unload the blocks. In closing, if I get a robo call asking to invest in this venture, I will not be investing any money in the experiment. endmrw0509161737

In the last 10 years only a quarter of the proposed coal fired power plants were built, and over a hundred were cancelled.  Only a handful are still on the drawing board.  You seem to think that this was totally because of some political mandate, however, half the states are fighting it, and the Supreme Court has yet to decide.  The politics is actually behind the times, as the free market (such as it is) investors have already put their money on gas fired and renewables.  As I said before, the free market will weed out the more costly methods of power storage.  If the cost of renewables gets out of hand, democratic societies will decide what level of cost/benefit they will bear.  That an essential system is built "unconstrained by cost consideration" is not behavior that I have ever observed.

Omigod, Pathfinder.  Yes, they fired it up; no, they never ran it at rated power; yes, that was a really fortunate thing.  Think nuclear superheater using 93% enriched uranium (that's weapons-grade to laymen) with 1960s control modality.  Not quite as shudderworthy as the Soviet nuclear superheater with carbon moderation, but definitely not something you want in your back yard.
