MIT ChemEng first author Shaylin Cetegen with Barton/MIT & Gundersen/NTNU:
Liquid air energy storage #LAES levelized cost of storage #LCOS for long-duration energy storage: ⅓ cost of lithium-ion batteries & ½ pumped hydro.
#LDES of 1day/1wk/1month, but not seasonal storage.
IMO looks like hydrogen still wins for seasonal storage.

Forget nuclear, Australia is on fast lane to 100pc renewables
https://michaelwest.com.au/forget-nuclear-australia-is-on-fast-lane-to-100pc-renewables-solar/

Australia's politicians have argued over renewables for decades. Some are wasting time on purpose and hyping nuclear power to keep us using fossil fuel.

Meanwhile, citizens and private industry have led the way with solar power. Australia is well on the way to 100% renewable energy — sooner than many people realise.

Forget nuclear, Australia is on fast lane to 100pc renewables - Michael West

A massive increase in solar power generation capacity is already putting Australia on the fast track to a 100% renewable energy future.

Why build nuclear power in place of old coal, when you could have pumped hydropower instead? #AusPol #Nuclear #PumpedHydro ?

Why build nuclear power in place of old coal, when you could have pumped hydropower instead?

Research reveals most of the sites the Coalition has earmarked for nuclear power plants would be suitable for pumped hydropower plants.

Last week I attended an event by @klimatriksdagen on #energytransition - it was interesting and educational!
My key takeaways:
1: #windpower has decreased in price by 63% since 2009. #nuclear power, has increased in price by 49%! 😮
2: Politics should remove fossil fuel #subsidies and invest in #energyefficiency !
3: Phase out #plastics from waste to reduce district heating #emissions
4: Secure a #sustainable #energy supply. Invest in #pumpedhydro & promote local #energycommunities 🌞🌬

New #PumpedHydro power project in Scotland.

This is very doable.

Not a panacea but the combined oomph of a collection of buildings could be very handy for many purposes.

Gravity could turn future skyscrapers into towering green energy stores

Concept could help decarbonise buildings, which represent 40% of global energy-related carbon emissions

This is very cool.

I had thought that this type of pumpped hydro power system was what we need a lot more of to use in conjunction with intermittent power sources like wind and solar.

Glad to know a few were built between the 60’s and 90’s and they are still operational.
They don’t have the fix number of cycle limitation of a chemical battery.

Ludington’s Liquid Power: One of the Largest Batteries in the World

Michigan’s Ludington Pumped Storage Plant uses excess electricity to pump water uphill, which generates power when it flows back down. This reservoir holds more than just water. Set on a bluff hundreds of feet above Lake Michigan, it also stores potential energy that can be unleashed to produce h

Battery storage is about to overtake global capacity of pumped hydro

Battery storage is about to overtake global capacity of pumped hydro | RenewEconomy

Battery storage is often dismissed as an "immature" technology, not ready for a renewables dominated grid. But within a year it is likely to overtake pumped hydro, and still has big advances ahead.

Hmmm...not sure about the future of the worlds largest proposed pumped hydro battery on a desert continent that is suffering forecasts for multi-decade droughts...

Perhaps its wiser to develop hydrobatteries at abandoned open pit minesites, not on agricultural land. Then you might be able to use saltwater.

Renewable energy and Green/Ecofriendly energy aren't the same thing.
