Great show! I watch most of Rosie's YT's and I listen to David Leitch on Renew's Podcast. I have a Very high respect for Both. I have a different view on the East-West Australia HVDC link idea to that of Davids. I am not dissuaded of it's merits (yet). As suggested, We should design our power network as a distributed system, as if they were hundreds ( thousands) of standalone grids, with local storage, Electronic Frequency / Inertia stabilisation, taking advantage of the best local energy resources. These local grids should be interconnected to other grids, preferably by DC interconnects (DC interconnects provides better decoupling and other advantages), to form larger networks, and same again forming larger networks. These interconnects provides important resilience. An East-West HVDC link would be the backbone, with stubs linking to Mt Isa, the SUN cable if it exists, other Major cities or industrial user hubs. There are HUGE Solar and Wind energy resources to pick up along the way , and we'll need these to electrify our mines, our future "green" minerals refineries (Green Iron, Green Aluminium, Copper and ....) . Forget hydrogen, this will make Australia a Renewable Energy Super Power. I don't believe private capital can understand the true potential, so it will take the National Government to make this happen.
That was a good show Rosie. If I get a non-Patreon vote, I'm interested in decentralised generation and distribution for the transition. Hearing David say community scale batteries and solar have a opportunity to be significant is exciting. These types of projects could easily be incentivised by governments, we had many remote communities cut off from the national grid with cyclone Gabrielle earlier this year. I'd like to find more information to push to various key players. I can't recall any in-depths on community scale projects from any outlet. Also pleased to hear a Australian to Aotearoa HVDC connection is a silly idea. 😊
Decentralisation of generation and storage is the only way to protect the existing grid. Today it is possible. New grid is stupendously expensive and would take decades. The grid took 100years and massive amounts of national wealth. NOBODY notices the number of poles and towers today. NOBODY notices the klm of wires just in the streets today.
Good show, Rosie. Please look into the business opportunity to provide electric storage by using new high efficiency processes to make ammonia which can be stored for long duration and turned back into electricity by either burning engines or flow batteries. This path has the advantage that when enough ammonia has been put away, the continuing production can be sold to agriculture for fertilizer. This is much easier and more economic than making and storing green hydrogen, which does not have an existing mass market for excess production.
I live in Southern California on the coast. Haven't had purchased any solar panels myself but I'd imagine I could cover all my power needs with rooftop solar.
Yes! 🙂 The mantra in Australia now is, regradless of shading (unless totally useless) etc, just cover the whole roof 🙂 The average new install, I believe, is over 8kW and heading towards 10kW
I think that the EVs with big batteries will make a massive difference. Most vehicles are parked 23hrs a day and drive building to building. All buildings are connected to the national grid. All buildings have roofs. So co-location of electricity generation and storage means the transmission of electricity is reduced and the grid will be UNLOADED. This is a massive economic advantage to the country. Millions of klm of poles and wires and transformers and switch yards and all to the streets and homes and businesses and industries and buildings and warehouses and shopping centres and millions of ends of the grid. No fossil fueled future. 5 times more electricity in the transmission grid. ??????!!! Impossible loading. The existing national grid is fragile but can be perfect if UNLOADED.
Not sure about his comments on spot trading. I don't think its something that people should do manually. It’s a job for a computer system to analyse data feeds and calculate arbitrage decisions every second. Not slow clumsy humans. I'm trying to set up EMHASS, an addon to Home Assistant, which takes solar forecast from solcast, FiT and supply price forecasts from amber electric and past usage history and calculate minute by minute what to do with available energy and household loads. While I'm still learning I think it will be the way of the future at every level.
20million EV is 2,000gwh daily of dispatchable electricity. V2G can be like a home robotic vacuum cleaner. SELFPARKING 23hrs a day. Today, 400gWh is fossil fueled generated daily. Rooftop PV can be 660Gwh daily. Vehicle usage is critical, horse and cart thinking is dangerous. Daily drive is only 10% of a full tank. So EV can be full every day with maximum range. DAILY.
Thanks for an informative interview. But please practice your interview skills. Remember that when you are interviewing (or chairing a panel) that what you know becomes a springboard to frame questions that your guest can answer from what they know. One or two sentences is enough for a question. Your guest can ask for clarification if needed. Thanks again. I look forward to seeing more of the informative and well considered content you produce.
From Ayr in north qld. Retired. Encouraged by everything happening to further aiding improvement of climate

I believe that the profit from coal exports is the same as the cost of petroleum imports.

Also places of work, as folks cars are parked up for typically 8 hours a day Monday to Friday in daylight hours
@@jimbobarooney2861 exactly.
Most people drive 1 hour a day.
Parked 23hrs a day.
The grid connection should be low powered and not rapid charge.

I really wished this was posted as a podcast instead!
