We produce heaps of LNG - we are, for the moment, the world's largest exporter - but not much oil. Anyway, leave it with you. We have had LPG cars for a very long time, most don't want those either. I suppose my point is that Australia could, and should, be doing a lot more to get the ball rolling. Not just electric cars, but Hydrogen too. Our govt has it's eyes on the massive shale oil deposits in the Northern Territory and does not seem to realise they are not viable until oil goes above $80/bbl, at which point, electric cars will be the much cheaper solution for motorists. If not fully electric, then certainly PHEV's. Half of our govt are outright climate change sceptics, and cannot see the forest for the trees. They do not understand that we will soon have a massive surplus of cheap electricity at a time when electric vehicles will become cheap. It is only 2-3 years away and the least they should be doing is pumping money into schemes similar to the German one whilst they can borrow near zero interest and we are in recession. They have made a start in relation to storage (Snowy Hydro 2) and transmission (2nd interconnector between Tassie and Victoria), but they still under-estimate the pace of change and cannot grasp the bigger picture.

I don't think they should be building new ones (far too expensive), but crazy to retire perfectly good ones! That, along with collapsing NG production in Northern Europe, is the reason that Germany still relies on Brown Coal. Nordstream will change that dramatically. So will German H2 production. ANY major disruptive technology has massive implementation costs (think autos replacing horse and buggy, introduction of computers/robots causing loss of millions of traditional jobs), but the end result is much more efficient and productive. 1 Quote Share this post Link to post Share on other sites

Now, if you were completely honest instead of just mostly honest, your statement would be more akin to this: Sorry, no, "renewables" are an entirely different subject than electric cars. Electric cars which require cobalt,nickel, lithium in large amounts that all must be imported... just like O/G. See, helping you out. 😁 Here is another line which is 100% valid: No real source of stored electrical energy other than pumped hydro, and garbage and no, Germany is not building pumped hydro. They are... doing jack all regarding energy storage and instead send their "coal power" to surrounding countries while claiming the "renewable energy". All the while denigrating their neighbors for not being "green". 😁 See, helping you out. 😁 1 1 Quote Share this post Link to post Share on other sites

For example, you imagine that putting in enough charging stations will overcome evident consumer resistance to buying EVs. Nope. Absolutely no evidence that is the case. As I believe that I've stated before, in Norway the government has basically bribed voters with major tax/road toll incentives equivalent to about half the cost of the car to get substantial EV sales. The result has been the better off families now have two cars - an EV for commuting and a petrol car for any serious trips. Poor people make do with what they can get. Charging stations by themselves won't do much. You have to have the rest of the very-expensive package. In the meantime the service station owners have to set aside a pump slot that would otherwise be earning good money for a charging slot and, as another poster pointed out, completely remake the station's electric system. You point to companies that will install charging stations for free, and say hopefully that maybe the government will handle the power upgrades. Again, I don't think you really grasped what's going on - the government has created a vast additional market. Those services are not going to stay free for long, and the power upgrades will be a major additional cost which someone has to pay for. Anyway, that should give you some idea of the vast problems with this initiative. I should leave you to your fantasies I guess, but I can't help myself. Leave it with you.

Germany has 40 GWh of pumped hydro. Germany has more than 200,000 GWh of NG storage. Yep, more than 5,000 times as much. This is many months of NG demand. I think you are talking about storage for renewable energy? If so, then you are correct. Nobody seems to have much long term storage for renewable energy. In today's world solar and wind is useful because the other generators can be counted on to handle the load when wind and solar are unavailable. Wind and solar reduce the need for fuel, but only when they are available. Short-term storage flattens the daily peaks. To get to 100% renewable, you need to flatten the seasonal peaks, which means long term storage, approximately on the order of the existing NG long term storage. 1 1 Quote Share this post Link to post Share on other sites
Dan Clemmensen + 1,011 June 15, 2020 About those chargers at gas stations: They seem to be mandating "fast chargers", not DC superchargers. In the US a "fast charger" is a SAE1772 level 2 charger: 240VAC at maybe 50 or 60 amp. It takes quite awhile to charge up, but the charger itself is inexpensive. Speaking personally, I would be quite happy if I could be confident that every gas station had a 50 amp level 2 charger. I would never plan to use one, but if I screwed up and miscalculated my range, I could pull into a gas station and charge up enough to get to my destination. As it is today, the best I can do if I screw up is to use my emergency level 1 charger, which takes forever. 3 Quote Share this post Link to post Share on other sites

Building out a public EV charging infrastructure will have challenges. But if battery prices fall I'd imagine consumers will buy shorter range EVs and/or PHEVs with powerwalls for rapid home charging. The main reason I bought a PHEV was for the convenience of refueling at home. If I was on the road with an EV and ran out of charge I'd only be interested in charging long enough to get home. I'm familiar with my driving habits so I doubt I'll get caught in a situation where I will need to use a public charger station. UK situation: 99% of domestic properties are on single phase power. Time to fully charge a normal petrol car replacement EV from empty is 15hrs. Power walls such as Tesla’s can only charge up to a third of the battery and have a 25 year payback. Granted you won’t need to charge from empty every night but if you have two electric cars you will have to stagger charge them meaning likely drawing 7Kw to charge most of the time you are home. If you add in domestic appliance use you could be drawing well over 10Kw I saw up to 13Kw on mine. Some UK domestic main fuses can not take this and might blow. Two interesting facts told to me by the guy who installed my fast charger. Most UK housing estates electrical infrastructure were designed for an average draw of 2Kw per household. Often when he went to a business (3 phase power etc) to install destination chargers they would say to him I want ten rapid chargers.

Tesla (in their infinite wisdom) think that the computer aboard the car is simply not smart enough to to optimize for very rapid charging. If the car cannot consult with the big brain on the Internet, then it will need to use a more conservative algorithm. How is this bad? Why would you ban it? In what sense did "everyone" pay for something they cannot use? Which "everyone"? A Tesla owner? a BMW owner? The owner of a charging station? each of these people knew or should have known what they were paying for. I know of no reason that you cannot invest in a car charging company that builds the charger of your dreams. I know of no reason you cannot buy a car that can use those chargers to their maximum capability, if one exists. How does this affect Tesla's decision to build charger they way they want to and to build cars they way they want to? Standardization is not authoritarian. Government-enforced standardization is authoritarian by definition. I think it's a good idea. 1 Quote Share this post Link to post Share on other sites

In northern and central Europe, residential electrical supply is commonly 400 V three-phase electric power, which gives 230 V between any single phase and neutral; house wiring may be a mix of three-phase and single-phase circuits, but three-phase residential use is rare in the UK. High-power appliances such as kitchen stoves, water heaters and maybe household power heavy tools like log splitters may be supplied from the 400 V three-phase power supply.

This is common misapprehension. Most US homes have "split-phase", not "2 phase". Nobody uses 2 phase as it has no advantage. "Split-phase" is single phase power, nominally "220 VAC" but actually twice the base nominal "120 VAC". The house gets two hot wires plus ground from the pole, and these two wires are 120 VAC with respect ground, but are 180 degrees out of phase with each other and thus 240 VAC with respect to each other. Three-phase power has three 120VAC hot wires at 120-degree phase offsets. Many single-phase high-power motors can operate by using either split-phase (240VAC) or two of the three hots of a 3-phase, which provide 208 VAC. the magic of 3-phase is that a motor that uses all three phases provides true constant torque, because three equal sine waves at 120-degree offsets sum to a constant. 1 Quote Share this post Link to post Share on other sites

Is this another ‘unfunded mandate’ from the government forcing businesses to provide a service without subsidizing the mandate? Like the unfunded mandate that 15 % ethanol/85 % gas mix as used in the US. Ethanol is a pure pork barrel program invented by ADM. We all subsidize the mandate every time we fuel up. Ethanol program is a combination of all bad policies in one package. Given a fixed amount of dollars to save carbon emission, probably a combination of nuclear power ,substituting coal with gas and hybrid vehicles would provide most. Ethanol most assuredly is not in that mixed, but it maintains the mode of agriculture that leads to soil erosion and unhealthy food mix -- cheap meat (corn to cattle feed lots, soybean to poultry and pork in megafarms) with expensive fruits vegetables.whole grains etc - several times more than in Poland, and perhaps double of German prices. Ethanol program subsidizes one Agrobusiness that specializes in producing it plus lets farmers to stick to alternating corn and soybeans with nothing else. Concerning Germany, they would save millions tons of carbon each year by not closing nuclear power stations. Quote Share this post Link to post Share on other sites

Those are DC "super chargers", which really do go up to 250 kW. The two DC conductors in the charging cable are really big, and the DC voltage in that cable is 480 V. I have no idea what is behind that plug inside the supercharger, but I very much doubt it's a 240 VAC input. See https://en.wikipedia.org/wiki/Tesla_Supercharger Very few types of EV have the internal busses required to actually draw 150 kW. New Teslas can do it. There is no way that Germany can mandate a DC super charger for every petrol station. They have probably mandated a SAE 1772 level 2 charger.
