Thread: Grid can go 75% renewable

except that wont fix the problem.

So when they build a NSW connector, SA will further screw over our coal fired power stations during the day while drawing on NSW power at night.
The Commonwealth had better get this gas fired stations up and running quickly.
This also implies that wholesale power will go negative cost during the day as SA tries to flog it’s excess.
Hpusholds will love no money from solar uploads if they turn off inputs during the day.

A few ideas be tried on using any excess energy for storage as Hydrogen make a lot of sense I think. Similar to pumped hydro but can be anywhere unlike pumped hydro . A few hydrogen electrolysis plants can be co located at sites which may have that excess at times and deficits at others its an effective margin play. Suspect we will see this sooner than later.

Happened already in Scotland.

Scotland’s Orkney Islands produce more clean energy than their inhabitants can use. Their next step? Hydrogen. Here’s why that matters – and what the rest of the world could learn.

It'll make storage financially viable in that case. It also wont be a good situation if everybody isolates themself from buying off the network.

Those rotten Sydney people are at it again. "A 500kW electrolyser" for “In the future Australians will need to decide what to do with excess renewable energy on very windy or very sunny days. Jemena’s Power to Gas trial will demonstrate how existing gas pipeline technology can store excess renewable energy for weeks and months, making it more efficient than batteries which can only store excess renewable energy for minutes or hours.”Frank Tudor, Managing Director, Jemena.

My issue with my or those batteries is they have a limited life 10 years and a limit on charge/discharge cycles. "The state has signed an $84 million contract with Neoen for the project" I bet that we are going to pay a lot more than 84 million for it!


I had to chuckle at this bit "Shadow Minister for Energy and Renewables, Ryan Smith, said the battery should be built 150 kilometres further west at Mortlake.He said it would be closer to other renewable energy projects, and less energy would be lost in transmission."

The power loss from or to Geelong or Mortlake would be negotiable. The price of land might be a bit more

VPPs are offered in Australia. Nothing new there.
