http://www.isentropic.co.uk/news/77/66/New-electricity-storage-technique-developed-by-Isentropic-Ltd-to-cost-less-than-30-of-Pumped-Hydro-Storage#6553964356269253

from the post: “The report also estimates a round-trip
efficiency in excess of 90%.”

What I don’t quite understand whether or not this reports supports Isentropic’s claims for $35MWh or less cost. It seems the larger the scale the smaller the costs. But I’m hoping someone with actual expertise might dive into the P K report and explain in more detail for laymen.

This also from the cited post: “Parsons Brinckerhoff is a leader in
developing and operating infrastructure around the world, with 14,000
employees dedicated to meeting the needs of clients and communities in
the Americas, Europe, Africa, the Middle East, Asia, and
Australia­Pacific regions.”

Also $10/kwh is an awsome capacity price. Compare this with lithium-ion, where your best price will be above $300/kwh.

The way storage of Energy from Renewables is tackled leaves much hope for these sources in the future.

Any technological advancement that makes it easier to justify using wind and sun power as viable alternatives to conventionally generated power is to be welcomed. One day in the not too distant future the world is going to be using alternative energy sources on a major scale.

Argon gas is used as the ‘air’. Argon is very abundant in the atmosphere and not particularly hazardous.

I don’t understand why they need to take build a demo project this large (think time and money). This concept should work (or not) at garbage can size and scale up.
