The future of energy generation and storage

Jump to new
Vanadium (better than Lithium) looks like the next big advance for batteries, storage in particular and they are giving them a 20 year battery life.

Forget fossil fuels, the sun wind and water currents will very shortly have it all licked. Vanadium can also store the power for up to a year.

Now they are starting to talk real renewables

I think the location is the most significant bit.

If gas is no longer a goer for electricity generation in one of the few places on earth where existing gas infrastructure is far more substantial than existing electricity infrastructure then that says it all really.

Biggest project being looked at in SA in that area is a 300 MW pumped hydro scheme on the outskirts of Adelaide at Highbury (about 15km from the Adelaide CBD). Company looking at this one is Tilt Renewables (ASX: TLT).

TLT are under a take over offer ATM. Good info smurph.:xyxthumbs

As you know LNG is reticulated over that region, so it isn't about supplying power to the NW grid, an 11GW plant to supply a 1GW load, I don't think so.
It is either for pumping water, or making H2 IMO, maybe both.
 
The pace of change is accelerating, Australia may well have found something sustainable to export. Not that I'm biased or anything.:rolleyes:

Another article, on the subject.

https://www.smh.com.au/politics/fed...-to-replace-fossil-fuels-20181009-p508mj.html

From the article:
Over the next 30 years, creating a hydrogen export industry to match the existing LNG industry would require several hundred gigawatts of extra dedicated electricity, meaning new solar and wind projects would be needed, Dr Finkel said.

I think there should be some long term caveats, put on this foreign investment into renewables, it all just seems a bit open ended IMO. It could become a bit like our Farm Land, overseas institutions buy it, with the obvious ambition of feeding their own people. There is nothing wrong with the principle, but we do need to have enough land and water left, to feed ourselves.
Maybe I'm just shadow boxing.:2twocents

From the article:
Risen Energy director of Australian projects John Zhong said the company intended to progressively invest in more than of 2000 megawatts of renewable projects in Australia, with later investments in storage.

I just hope we don't end up in a situation like the LNG problem over East.
If foreign companies, end up owning most of our renewable generation, then install Hydrogen production facilities for their own export market.
We could be left with no capacity to produce enough for our own needs, it just seems like we are going to be the mules to get the renewables installed, with no say in what the storage capacity is used for.

It could be used for stand by generation, transport fuel and or export, unless the guidelines are put in place early, it will be hard to implement controls later.IMO :2twocents

Electricity distributors warn excess solar power in network could cause blackouts, damage infrastructure

Someone has to find a way to store all this excess power.

Like we have been saying frequency control and system stability, is a real problem. It can be overcome, but it will cost a lot of money, that is the whole problem when you make change in an uncontrolled ideologically driven manner, instead of being pragmatic about it.
It looks as though it is at least coming to a head, so the narrative can turn to how we achieve a reliable electricity grid, rather than just keep throwing renewables in and shutting synchronous generators down.

Maybe more incentives for consumers to install Powerwall systems instead of feeding excess into the grid.
