> If large scale battery storage is already cost competitive with turbines and there is still more low-hanging fruit, then presumably battery costs will continue to fall faster…

I don't see a lot of realistic talk about what the actual storage requirements are. You have to be concerned about: (1) ordinary diurnal variation (overnight, lets say 12 hours)…

This where system thinking, or the lack there of, becomes an issue. You would be right if we only had exactly enough capacity for four hours of power. But of course with batteri…

> four-hour storage is forecast to fall a further 33% to $80/MWh by 2035, displacing gas peaking on cost across every gas market in the region. This seems to be specificall…

It's a different kind of manufacturing. China leads the world in battery manufacturing, it's not really so hard in an absolute sense, but gee do you have to get the cost down an…

The market for aircraft engine gas turbines is at least 5x the market for industrial gas turbines. We could eliminate natural gas for electricity overnight and GE would keep spi…

A turbine is a rotary mechanical device that extracts energy from a fluid flow and converts it into useful work. The work produced can be used for generating electrical power when combined with a generator. A turbine is a turbomachine with at least one moving part called a rotor assembly, which is a shaft or drum with blades attached. Moving fluid acts on the blades so that they move and impart rotational energy to the rotor. Read more on Wikipedia
