Liquid air energy storage

Now we have the first plant in operation, and will be able to judge how efficient this storage method is;

 

[Donald H]

Storage capability would seem to be an important factor. But as far as I can determine this is about that and nothing else.
The real question might be on the amount of loss experienced.

Well, hold on a minute, let's

 

[Mr. H.]

The video doesn't address the energy inputs required to operate the plant on a continuous basis. Nor does it address the facility's true carbon footprint, from concept to design to manufacture to transport to assembly to operation and maintenance to decommission to ultimate disposal.

This very same thing can be accomplished with compressed natural gas (CNG) of which there is plenty available today. And it can be done with virtually zero input loss due to recapture, recompression, and reuse.

Wow, so no more fracking! Who knew?

Liquid Air Energy Storage: A Power Grid Battery Using Regular Old Ambient Air

When you think of renewable energy, what comes to mind? We’d venture to guess that wind and solar are probably near the top of the list. And yes, wind and solar are great as long as the winds…

Batteries are definitely not the ideal storage method

Batteries are definitely not the ideal storage method

Batteries are ideal for balancing the grid and quick response. Pumped hydro is great for long term energy storage. And there are many other methods that also have their own advantages. There is no reason to just consider only one type, or not use more than one type of storage in tandem with another.

First of all, the energy input is from solar or wind that would otherwise be idled because it was not needed at the time. Second, a natural gas plant is a fossil fuel plant, and that is what we need to get rid of. You fellows really seem to be a bit dense.
