Helpful video !
High technologies !
I literally melt...
Thanks dear FT !
I appreciate it !
Paris goals are just goals... No one enforces them..
Self-sufficiency in power and generating power without mining or using a vulnerable fuel infrastructure is more important..
Blah blah
Doing effort in all areas is important for the future of our planet. These projects are as important as any other ones
@@markj2093 but the people receive the energy they need
in addition the country can begin to use ocean wave to to generate electricity to the grid
if it replaces coal then hydro would power the pumps for pumped hydro
what would be the carbon pollution in that process?
Actually, one small fault there. Australia is actually on target for Paris agreement (26% reduction on 2005 levels). Indeed, current projections suggest it will exceed this - probably as high as 30%. Nevertheless, pumped hydro is one way of helping cover the black spots on the grid, piggy-backing on an already hugely successful hydro system.
Are you Australian? Our government essentially has been (until recently) using dodgy accounting tactics to make us appear better than reality. We are not on-track to meet the Paris Climate Agreement but are making steps in the correct direction.
Great content, I wish the vid was longer
This was talked about in Ontario 50 years ago but the problem is suitable storage sites. S. Ontario is too flat. It might work for Norway, BC, and the likes, if they also have thermal energy stations. It is only attractive to those utilities using thermal generation to provide the base load. Ontario, for example, mostly uses coal, gas, oil, and nuclear. These stations run 24 hours a day, because it takes hours to get them up to operating temperatures so they can't just be "turned off" when things are slow. Overnight, especially, the excess and unused power just dissipates and is wasted. Pumped storage advocates using the lost energy to pump water into a reservoir and use it as required, usually for peak energy requirements. Sorry if I haven't explained this well. It has been a long time.
Why are there no dams with more than one bank of turbines ? IT can be made see rdp marine australia 3 banks of turbines no added flow needed
Helpful lecture
What they gotta do is figure out a way to use large ram pumps with this, so they dont have to use any other power source at all for pumping the water back up to the top, maybe smaller pumps for the waste water from that ram pumps, but thats it.
Haha genius.
I think we would our hydro to help wind and solar renewables in BC Canada like this too. When wind, solar PV and hydro can work beautifully together we can build our future.
what if the upper reservoir evaporates too fast? any inlet of water needed?
There are two other sources (Eurcumbene lake, which is huge and Tumut Pond, also large). These feed hydro plants downstream, after which the water can be pumped back up to the pumped hydro feeder dam in required.
You do have a snow melt every summer which tops up the reservoirs. you also need environmental flow for the rivers. Part of the Snowy Mountains Scheme where the elevation and climate is a lot cooler.
Water level + rain - evaporation +inflow = ??
Australian goverment is smart..
Good..
The price of solar, wind, electric cars and storage may do the job alone of carbon free but hydro storage may help too.
You need to expand on this explanation. Wind, solar, and the "new" energies are not reliable for base loads. Electric cars require electrical generation to be generated somewhere. Pumped storage is only useful if there is wasted energy from thermal generation and a feasible storage place.
With federal and state subsidies new wind is now 2 cents per kilowatt hour and new solar PV is 3 cents per kilowatt hour in the US which is then sold to competitive utilities. With huge solar and wind and now offshore deployments along with hydro balancing, grid batteries, residential batteries and bidirectional electric vehicles, we will see more decentralized, democratic energy. The Tesla 100 MW Powerpack battery system connected to a large wind farm is going well and making money. We also now know modern huge, wind turbines repay their embodied energy used in mining, smelting production and transportation energy in under 6 months. Solar PV returns 14 times and in Arizona 27 times the amount of production energy (equivalent in electricity) if connected to the grid from export, off site or used on site for extra activities. SunPower PV panels are the first to be Cradle to Cradle Certified for circular economy. Commonly during a sunny afternoon a solar PV system is full and there is more solar PV electricity production than needed. For example, California exports solar PV electricity to Arizona when it generates too much. Night time wind generated electricity is exported to the US from Ontario. To harness this extra electricity, thermal mass in floor tiled electric heating could take a lot of electricity for later family warmth and comfortable. Thermal mass tiled floors that are well insulated bottom, walls and attic in the house carry heat for hours and hours...warmth and warm toes. This works best in highly insulated homes, buildings and offices making them far more comfortable for clients, shoppers, families and citizens. The next level of excess energy storage would be community and regional grid batteries, residential batteries and electric vehicle batteries in cars, buses, pickups, semi trucks and high speed trains. Sooner the better. Better, cheaper, cleaner, let's go!
Australia has Huge Amounts of Solar Energy. Therefore Heat Storage will be a Competitor and may be Superior to Pumped Hydro. If we ever Get Serious about Renewables and Leadership.
Chris, you need to watch the video again. Pumped hydro is designed to help solar, by storing the excess energy and distributing it when required. Ditto wind: Stored energy will be used when the wind is not blowing.
We do have gas fields that could be used for underground storage and around half our water comes from desalination so maybe you are right, its just that I'm not aware of any existing underground caverns we could use. Excavation is expensive you know! Above ground air storage is likely safe enough but haunting for nearby residents.
@@namanish450 I Don't Know the Full Fossil Fuel Facts for Sri Lanka.
But Sri Lanka Certainly Should Build some Off Shore Wind and Off Shore Tidal Generation, ASAP.
Plus Use More Solar in Their Built Enviroment.
Namanish, Hope Your going OK over there in Sri Lanka.
