D Coyne + 305 DC March 19, 2019 13 hours ago, NWMan said: the above chart / conversation assumes that electric vehicles are going to be power by an other energy sources - not oil and gas. What is this energy source that within 14 years it will replace 40 million barrels equivalent of oil and gas? NWMan, This is a focus on oil. The energy would come from natural gas, nuclear, wind, solar, and coal. Note that from tank or battery to wheel, a BEV is far more efficient (fewer energy losses). Combined cycle natural gas has up to 60% conversion of primary energy to electric power, so overall energy used may be reduced, in the case of solar and wind, losses are far lower than thermal power production as in fossil fuel or nuclear. Widely dispersed highly interconnected wind and solar requires very little backup (maybe 10% of average load over an annual period on average), natural gas, vehicle to grid, pumped, hydro, fuel cells, and batteries as well as demand side pricing to reduce peak loads can easily provide the other 10% once wind and solar capacity ramp up to replace coal and natural gas.

Heck, back around 2014 or so I was all gung ho and pretty darn vocal about U.S. Shale Oil making America Energy Independent. I've since modified my opinion about that over the years, as a certain Mike S. and Enno and a few others presented some disheartening facts to counter the Mainstream Media and Wall Street hype. Anyway, my current views are I tend to see roughly $70 Brent and $50 WTI for this year. For background, here is one of my old comments from May 2018: My view on oil prices are pretty clear. I've been pretty consistent about my views on oil prices since 2015. But since I'm new to this forum, guess I need to reiterate. In 2015 and 2016 I commented ad nauseum (mostly on the new defunct Oilpro forum) that I would be happy if oil was a stable average around $50 to $60, but closer to $50. In 2017, I changed my view and comments to I would be happy if oil was a stable average around $50 to $60, but closer to $60. This year, I changed my view and comments to I would be happy if oil was a stable average around $65. And I would be happy if oil was a stable average around $70 for 2019. Note that I think the value of the US Dollar will be devalued a bit later this year and early next year as the PetroYuan starts gaining international acceptance. So in real terms, I'm actually hoping for oil prices to average $65 for 2018 and 2019. $100 oil is not sustainable long term. $300 oil is just nuts. Excessively high oil prices would kill global economies, and crash oil prices all over again. Thanks Tom, From that comment I had $65/b in my head, in that comment when you say "oil Price", which price do you mean? As you well know there are many, I focus on Brent others use WTI, the spread has generally been about $10/b in recent years rather than $20/b. Do you expect this relatively stable spread (2012-2018), to shift to $20/b? If so why? Note I mostly agree with your prediction through 2020, but I think we might see oil prices approach $100/b by 2025, but possibly prices will go down after that as BEVs ramp up (though my recent scenarios are far too optimistic and should be considered a lower bound for demand for oil.)

Now ceramics have improved, but that is what we would be looking at, ceramics.... in a crash. Second reason they have not gone to high DC voltage is safety. High DC is much more dangerous than AC, but this can be addressed by design with safety pull tabs before opening battery. Just increases cost. Not a barrier. Gets back to crashes and people working on cars though. Third reason they have not gone to high DC voltage is efficiency. Upvolting something is not efficient. Why packs were made for standard 240V. To efficiently go to 480V AC, EVERY home service entrance cable would have to be changed along with EVERY transformer in the world... Or suffer the inefficiency.....

YOur solution is opposite economics... MORE expensive power... Listen to yourself man. And your math sucks. A 50KWh battery has a capacity brand new of 40KWh. Some of which was used getting to work and who says it was charged overnight? Most likely not, as people will not plug in if they do not have to. An older battery will have 20KWH useable and last I checked you have to do errands before going home which your wife calls you to do or pick up the kids and you need an extra 50miles, not your 10... Reality is you can play with about 10KWh of the battery.... Yea, bravo... you can make a $1 a day if you plug, unplug every day.... Yea right, as if a business is going to install a $10,000 dollar upgrade for $1 a day... want to go to the extreme? $2. Not your $20. Progress in society happens when CHEAPER, more robust solutions occur, not more expensive, time consuming, more complex solution trying to find a problem occur.

I'm sorry but you are clearly not up to date with your info in terms of batteries. Batteries are approaching 300Wh/kg (Maxwell for instance have demonstrated this) and there's a good chance that there will be 500wh/kg battery tech by 2030. We'll se how well ICEVs hold up against that considering that they can't hold their ground even against 250wh/kg battery powered vehicles in the relevant cases where longer range EVs are available to compete. Also, I'd like you to list all the fires that a Tesla vehicle has suffered. I'm willing to be that there are less than 20 such occurrences over the last 10 years so you are discussing a very rare eventuality as if it's a common everyday occurrence. The chances of experiencing a fire in an ICEV are likely greater. Edited March 19, 2019 by David Jones 1 Quote Share this post Link to post Share on other sites

Please provide some reference about your assumption that 250wh/kg has been the norm "for a long time". You are simply throwing out random, self generated "facts". As far as I'm aware, research has shown that battery energy density improves at an average rate of about 3-5% annually. Maybe you consider a couple of years to be a while? When considering a couple of decades, your statement is clearly false. You can actually see an example of this wh/kg improvement on the Tesla Roadster vs the Model 3. The Roadster in 2008 is generally considered to have about 120wh/kg, the Model 3 is closer to 170wh/kg at the pack level. That is >40% increase. Assuming that the car industry will indeed be pushing forward with EVs as they have mentioned (this seems more likely based on recent developments), much greater R&D efforts will be made on a global scale to improve energy density. Regardless of the eventuality of a 500wh/kg energy density for the batteries in 2030, another 40% increase by 2028 is well within the normal battery development rate. That means a Model 3 equivalent in 2028 would have about 325*1.4=455miles of range. Well above the average car range of ICEVs.

I wonder what your definition is for "on the horizon".

BEVs typically charge in the wee hours in the night when the grid strains to unload electricity. They consume during the hours when the grid is maxed out. To they serve to load shift. You can also set up EVs to be storage that feed the actual grid. It increases the cost of a charging station, really kind of silly for most. So theoretically it works to level the grid. I don't buy that, but it is a bit of load shifting. 1 Quote Share this post Link to post Share on other sites

Difference between lead acid, gel, AGM, Carbon Foam... All have have ~ same power density, some are slightly better than others. By the way, Firefly Carbon Foam batteries are the best in the world in terms of $$$/KWh with high cycle life and are 50% cheaper than Lithium.. Here in reality(Does not have new NMC(200+ Wh/kg.): https://www.batteryspace.com/li-ionsinglecell.aspx We have been using lithium poly for 25 years at over 200Wh/kg. Theoretical for lithium chem is around 250. You can dance around this number +/- 30%, but no new chemistry on horizon PS: learn how to read. A capacitor is not a battery.

Lol, it's like your brain is frozen in time. Apparently, your opinion and some random website that sell standard market batteries is more accurate about the current state of research on batteries than the actual articles assessing this as well as an Aerospace military contractor, Collins Aerospace president for power and controls Edited March 19, 2019 by David Jones Quote Share this post Link to post Share on other sites

That and a subject called Chemistry Quote Share this post Link to post Share on other sites

That and a subject called Chemistry Yes, because you are an insider at Collins Aerospace and know their purchasing strategy. Either way, it looks like I'm just talking to a wall here so there's no point in wasting more time on this "conversation". We will see what happens by 2025. My bet is that we will have EVs with ranges approaching or even exceeding 400 miles by then. You can argue your delusions on what has happened during the last decades in terms of wh/kg all you want but you cannot argue an increase in range with lower price for the vehicle. Ultimately, that's what counts regardless of how it was achieved. Quote Share this post Link to post Share on other sites
