And a very valid set of arguments especially considering how respected he is in the battery field and Tesla have actually researched the scenarios on numerous occasions over a period of time and each time still come to the same conclusions.

Apparently, the Tesla Roadster had the ability and was tested to act as V2G, it was dropped in later vehicles.

Tesla delivered only 1,550 of its new Model 3 vehicles in the final quarter of last year, well below the 5,200 consensus forecast of Wall Street analysts, as it struggled to overcome the production bottlenecks that have bedeviled its make-or-break mass market car.

The US electric carmaker also pushed back its target for hitting a production rate of 5,000 a week of the new cars to the end of the second quarter, three months later than it had projected. The delay comes only two months after it last pushed back the 5,000-a-week target by a full quarter.

The latest signs of Tesla’s production headaches with the Model 3 wiped nearly 2 per cent off its shares in after-market trading on Wednesday, leaving them 20 per cent below their peak of last summer.

However, the company said it had made “major progress addressing Model 3 production bottlenecks”, with output picking up late in December. Production during the quarter reached 2,500 vehicles, many of them too late to be delivered before the end of the year, the company said.

The first Model 3s, priced from $35,000, rolled off the production lines in July, though Tesla had delivered only 220 of them by the end of September. At the time, it blamed its teething problems on mastering the complexity of a production line in the Nevada plant where lithium ion cells are packaged together into modules, before being assembled into final battery packs.

Think Tesla are getting left behind here. Nissan and Enel have already proven that the technology works now its just a case of scaling up.

The other side of the Tesla Q4 production figures story is that they made record numbers of both Models S and X, so even though full ramp-up for Model 3 is going slower than hoped, they're pushing out their other cars like never before.

There seems to be a number of different opinions on whether V2G and battery recycling/reuse are beneficial.

Some think V2G is a good thing, some think reusing old vehicle batteries is a good thing, some believe that dedicated car and home batteries are best (and economical) and some believe that remanufacturing batteries from old raw materials is the way to go.

Nissan seem to believe in the former 2, Tesla believe in the latter 2. Just different opinions (that Tesla apparently reassess on a regular basis) derived from the different models created to assess this.

Don't think its a case of Tesla getting left behind. They can do V2G if they wan't, they just don't see the need at present. All solutions can be right, but maybe not in all cases. There is probably not one solution that fits all.

Personally, once home batteries get cheaper (if I could get a Tesla Powerwall 2 fully fitted for under £3k I would not hesitate to buy one right now, but its twice that), I would want a dedicated home battery and a dedicated battery in the car. Coming up with generic solutions that fulfil many different scenatios generally creates compromises somewhere - jack of all trades, master of none. Which is why Tesla use different battery chemistry for daily storage, backup storage and EV's. Personally I like to keep cars a long time, may be a different picture for those who change frequently or lease/hire theirs and don't care about any potential premature wear (that may or may not occur with V2G) on the EV battery.
