  2. Local stationary energy storage for sustainable energy systems doesn't require high energy density though, which is the expensive part and also the very dangerous part. For bulk stationary storage the only requirement is that it's very cheap per unit of storage and can operate at part-charge without damage. Unfortunately, lead-acids don't fit the bill because even though they're relatively cheap and very safe, they get damaged unless maintained at 100% charge. Nickel-based chemistries are too expensive, lithium-ion is far too dangerous in large aircraft-hangar sized installations and tends to be very expensive as well. Perhaps LFP (lithium ferrophosphate) cells would be a good intermediate solution for local bulk storage but they are still far too expensive. Their cycle life and calendar life are outstanding, though. For large cities like Toronto, Montreal, NYC, L.A. and the like, having huge local battery storage systems might be a really good idea to relieve power stations from conditions of peak demand. It's just that battery technology is too dangerous and much too expensive right now. The highest possible energy density is only necessary for EVs, and is especially necessary for electric aircraft. The best current battery tech is much too dangerous and expensive, so even the best EVs are a very costly niche product and likely will remain so for many decades. They can get away with it for relatively small numbers of very expensive luxury & performance oriented vehicles, but EV still have no way to compete with internal combustion engines for low cost and high practicality & convenience. Long-range low-cost practical air travel entirely on green energy is a dream for the future--and an actual goal for the distant future.

  7.  @henribasson5489  That's the term I was looking for! Utility Scale. At that level the only thing that really matters is total cost for the total energy throughput (watt-HOURS per dollar) and that's it! Total cost of implementation versus quantity of energy storage is all that matters for a stationary application. That includes fire insurance for "touchy" chemistries. For solar power, the energy itself is not only universally plentiful, it's 100% free. It's the human work required to make practical use of it that's unacceptably expensive, and that's why the world is almost hopelessly dependent on fossil fuels. It has nothing to do with the physical aspects of "technology" in the usual sense; the purely gadgetry-oriented sense. It's the poor cost-effectiveness that puts sustainable energy on the back burner while the human species continues to compete ferociously for money itself in the name of power over people and sex. Those three things are what the world is about: Power, money, and sex. Sustainable energy isn't profitable enough or practical enough just yet to become a primary goal for the human species because the use of "canned" energy from finite resources is still more profitable. Only after the world runs very low on fossil fuels will our economy adapt itself to make the effort to develop sustainable energy. Until we reach that point, you can do your part to help things along by getting a super-thirsty gas-guzzling vehicle and a huge McMansion that burns fuel and money to heat it and cool it.
