Smart Grid's Enabler - Alternative Energy Storage

Old wizzard- building out the grid can be as simple as providing a canal large enough to function regardless of the leaks.

Smart Grid's Enabler - Alternative Energy Storage

Tiny tim = pumped storage doesn;t nrecessarily go thru the same turbines.

Smart Grid's Enabler - Alternative Energy Storage

BWA - right on; end-use storage: add on a little stored heating and/or cooling via products that exist and are already used (refrigerators [ice] - simple thermal storage - get rid of the standard ovens/stoves and their 220v hookups and anything "red". Avoid any conversion inefficiencies wherever possible (like batteries!).

Instead, push local/remote no-moving-parts biofuel injected solid state generators that capture/and or make use of all the energy; no conversion losses on the way in or out. John will be able to invest in these SOON. Then we can throw away many of the other schemes. Oh yes, and God DOES NOT forbid solar PV and wind, at the home, etc., jic.
Nor hybrids on the hyway.

And on the front end, pumped hydro opportunities do exist and are only complicated by regulators, of which we should eliminate about 80% (or more!).

Amazingly, according to JOhn, less that 1/2 our electrical generating capacity is utilized. So that 12 Quads of annual electricity we do generate (at 40% effeciency because of not using the low pressure steam) and the grid we already transmit and distribute on (losing max 10%) could easily be bumped up 50% using existing technologies and with the extra 6 Quads we would have enough energy to electrically power all the existing Transporaton industry that currently consumes 25 Quads and produces only 5 Quads or useful work, wasteing 20 Quads (80%) of it's energy from all the crude in the internal combustion engine conversion. Come on electrified interstate ferries and grid.

Throw in the solar PV and wind AFAP (as fast) and AMAP (as much) and our problems are solved. Storage?? Come on LEADERSHIP.

Alternative Energy Storage Stocks: Review and Outlook

john = re. Toshiba's battery. Nothing strange about fast charge rates (2C) for significant portions of a recharge; especially up to the 80% charged region which is when inefficencies cause more substantial heating and gassing. Fourty years ago we were recirulating and cooling the electrolyte to achieve fast recharges for 20 kwhr batteries.

Alternative Energy Storage: It's All About Price vs. Performance

John- We must not lose sight of this chart - it is the one from which our energy policy should be developed.

Alternative Energy Storage: It's All About Price vs. Performance

John - AEI should practice what you preach "you are going to tell us what IS, not what MIGHT BE". I believe their presentation is very indicative of the handle our Government has on the energy issue (sources and uses both - and everything inbetween and after!). NOT GOOD!

Alternative Energy Storage: It's All About Price vs. Performance

John - I reviewed the whole presentation; I do believe the "Gaseous" components are indeed shown and visible for 2007 and 2015 as small as they are; and, my guess is, they are also included in the other years but are too small to be visible. Makes one wonder. However, their assumptions must say that "Gaseous" driven vehilces are going to be few - and they go on to prove it (predictably).

I have greater issues with their charts, specifically #11, which shows just WIND generated electrical power in 2030 being greater than all electrical generation of 2007 (>100 quads).

What's more troubling, they show all electrical generation at >400 quads in 2030, 4x today, and still show now reductions in all liquid fuel consumption: hence, no reduction in "burning" as we switch to the electric economy. Something smells.

Alternative Energy Storage: It's All About Price vs. Performance

PS: John - unless it's in their definition of "Light-Duty" - which is possible, as most of those applications will likely be fleet service and not in the hands of the conumer.

(along with pressurized/compressed... was liquified/synthetics, etc.).

Alternative Energy Storage: It's All About Price vs. Performance

John - it's possible (I'm assuming) that 'Gaseous" includes pressurized/compressed... etc., gases be they propanes, methanes, hydrogen, etc. I doubt (hopefully) this astute crowd preparing the chart would overlook such.

How Will Temporary Decline in Oil Prices Impact Energy Sector?

Right on John - when I mentioned golf cart evolution I would have been better serving of the folks to have said scooter evolution: some of the 3 wheel transportation vehicles are beginning to get attention.

How Will Temporary Decline in Oil Prices Impact Energy Sector?

closed book - closed mind. Watch out for Govt fiat - whether in the US or some other smarter countries.

How Will Temporary Decline in Oil Prices Impact Energy Sector?

John -
1. When the US decides to give up 2 million gallons a day the world will be awash in fuel. And that will continue..... until we are at 6-8 million instead of 21 million a day. The rest of the world will have its fuel if it wants it. The price of crude can do many things; the actual US consumption is going to decline.

2. There is a market for < 50 miles per day electrics. The rich will do what the rich do. The rest will eventually have a cheap legal throwaway PV, probably evolving from the likes of golf cart, instead of Detroit down. Others will enjoy the efficiency of moving people in transit systems - they will come in one form or another.

3. Hybrids will scratch the itch of the <50 mpd and of course satisfy the needs of the >150 mpd crowd.

4. Before we die, there will be an affordable hybrid electric vehicle powered by a no-moving parts injected biofuel combuster encapsulated by solid state waste heat direct to electric converters powering 20-40 hp electric motors with the only on-board storage device being a GRASS TANK refillable everywhere to provide unlimited range; these vehicles will have no transmission, differential, etc, These will satisfy the demands of both automobiles and trucks, not to mention locomotives and other industrial equipment - maybe even these first.

Alternative Energy Storage: Why Frequency Regulation Is Important

John - one does not want to spin steam - that is like having your ICE idling while stopped in traffic: come on EV's!

Here's how to do both on the demand side. Real data.
