Clean power 2030 - Transmission (Joe Bush - Modo Energy)

[@dac545j]

Thanks for the very interesting content. As I've been living abroad for 30 years now (unbelievable) I'm not used to the 'upspeak' coming out of Britain nowadays. Definition: "Upspeak can be used in both questions and non-questions without breaking any grammatical rules. However, some people find upspeak unclear and may convey a lack of certainty in the speaker. Others may find it annoying, and some news articles have suggested that it could hinder job prospects. "

14:00 That's why battery power plants are needed, *much much cheaper* (factor 5-10) than building power lines!

[@RB-eg7mj]

Modo love your podcasts. I've been following new energy for a while now. Please can someone explain where the money I pay for my energy bill in the uk goes? An actual deep dive. Its obviously very complicated however for an average consumer its a black box. It is imperative that they energy sector communicate this to consumers otherwise this leaves the door open for conspiracy.

Ofgem have a good explainer, if the right guest comes up we’ll make it happen www.ofgem.gov.uk/understand-your-electricity-and-gas-bills

In late 2020 China set a target of 1200GW of renewable energy capacity from wind and solar by 2030. The year closed with a combined wind + solar total capacity of 463GW . Up 50GW from 2019. But interestingly China achieved its target of 1200GW capacity by June 2024.5 years 6 months ahead of target. This is the result of cooperation between the central government, regional governments, state-owned companies, private companies and the community. I doubt this could be done in uk .To achieve the 2030 Target.

It will be, once all the battery containers from China arrive and make the grid eager to suck in as much renewable as can be installed, because "Wind+Solar+Battery+UHV" is cheaper than any other form of energy!

[@cyberslim7955]

17:00 Still much cheaper than Hinkley Point C? Have you simulated in the grid what battery power plants can do, or is this all still guess work with totally old assumption, where kWh prices were at $1000?

[@grahamcook9289]

Reduce domestic and commercial grid demand by wholesale roof top solar PV, rather than keep on subsidising grid level generation with wind farms and nuclear via retail customer power bills. Also change wind turbines from a corporate ownership/operation model to a cooperative model with the owner/operators being retail grid customers who receive a reduction to their bill in return for their investment. Even without domestic solar PV install storage batteries to charge overnight in winter from wind turbines. ob cheap rate, rather than curtailment when there is over production.

[@grahamcook9289]

They should install a grid interconncetor cable to both Orkney and the Outer Hebrides along with commercial wind farms on these archipelagos, as has been done with Shetland.

[@simonmasters3295]

Uh? Just why would Scotland sell England that power? The market?

[@lkrnpk]

"if you compared with historic rates" Solar historic yearly install rates here in Latvia: 2017: 5 MW 2018: 5 MW 2019: 5 MW 2020: 6 MW 2021: 7 MW 2022: 100 MW 2023: 200 MW 2024: 300 MW 2025: 600-700 MW perhaps? This is yearly, not cumulative :D

[@grahamcook9289]

50GW renewable? Wind is 28.5GW, Solar PV is 15.9GW and hydro is 1.4GW. That 45.8GW. Pumped hydro is 5.9GW. You can't count biomass (trees) as renewable in any practical sense as it takes so long to grow the replacement tress and it causes pollution. The historical record also shows the maximum generation achieved for wind 21GW and for solar PV 10GW. But don't forget the dunkelflaute! Until there is viable long term renewable energy storage, gas thermal generation equivalent to total demand - minus nuclear generation, will still be needed. But gas has less than 60 years to go before depleted. THE CHALLENGE WITH RENEWABLE ENERGY, GIVEN WIND, SOLAR PV, HYDRO, GEO-THERMAL, TIDAL, IS NOT GENERATION, BUT STORAGE THAT TURNS INTERMITTENT GENERATION INTO A DISPATCHABLE SUPPLY TO MEET DEMAND 24x7x365.

Targets for 2030 are 50gw offshore, 27gw onshore and 47gw solar. I don't think these guys went into Virtual Power Plants (ie homes with v2g and/or home batteries) which, although short term storage should by 2030 significantly reduce the amount of grid scale storage needed.

[@stephenbrickwood1602]

The grid is a fixed cost investment that needs a ROI,return on investment, based on it's value. In Australia The national electrical grid is 1million km. Grid valuation/construction costs are $1million to $10million km. The grid is an investment valued at over $TRILLIONS, and needs $100BILLIONs in cashflow from the 20million customers. When the sun shines the customers with rooftop PV do not need grid electricity. After the sunsets the customers with v2g battery vehicles do not need grid electricity. Grid electricity $kWh will increase as cashflow ROI is to be maintained as customers cash leaves the grid. Rooftop PV and EV big battery parked 23hrs every day can be an asset to the grid owners if cheap feed-in and the unloaded grid can now supply the industrial users moving away from fossil fuels. This concept of grid dynamics and customer grid relationships is rarely spoken about. More grid is f...king expensive. More electricity and less fossil fuels needs clearer thinking as the latitudes warm.

[@grahamcook9289]

Battery energy storage alone is not the answer. We need to develop GWH liquid air storage.

[@grahamcook9289]

Yes mate, but what the dunkelflaute???????? Where's the viable long term renewable energy storage?

[@wotireckon]

According to these guys, that's where the 5% gas comes in, obviously along with nuclear. As for long term storage (say up to 3 weeks), it's a question of how many batteries. If gas & nuclear can't do it alone, we need more batteries. We'll probably need a shit tonne of them to get us through dunkelflaute - but imagine the massive excess of storage capacity during hot windy summer periods! We could have so much excess that we'll need to get inventive about what to do with it. Hydrogen (for fertilizer, not burning!), water desalination etc, or just plain old exporting.

[@grahamcook9289]

@@wotireckon Current lithium battery storage is only good for grid balancing and peak demand periods of a couple of hours. Pumped storage is better for up to 6 hours, but longer than that requires a more affordable and scalable solution. To my mind liquid air, or cryogenic storage of mainly nitrogen is the most promising emerging technology.

[@stephenbrickwood1602]

Nuclear is too small to stop Australia CO2. Nuclear can only supply 5gW to 7gW. The Australian grid is 25gW max if you are lucky. Australia needs 250gW if grid electricity were to replace fossil fuels. The 25gW grid costs $1million × 1million km = $1TRILLION. Grid costs only. Nuclear promoters say upto $10million per km. To increase grid capacity to millions of customers is $10TRILLION and no fossil fuels. Grid customers are replacing their grid electricity and their gas heating and cooking and hotwater and imported petroleum with rooftop PV dirt cheap electricity and house battery. With v2g technology then customers can use their vehicles to store daily massive amounts of electricity. Most vehicles are parked 23hrs every day. Customers will not need grid electricity. Customers are the cashflow in the Australian economy. Grid owners know this. Grid cashflow is $110billion per year to the existing national grid. At max demand. Grid owners will not spend $TRILLIONS to expand the national grid capacity. Grid owners will not clog up their existing capacity to dead duck nuclear economics. Grid owners will partner up with grid customers and new grid demand from existing industrial customers moving away from fossil fuels. Existing customers with rooftop PV and v2g EVs can remove their demand off the grid and become dirt cheap suppliers of clean electricity. Central clean nuclear electricity can not distribute its electricity without grid owners and grid owners will follow the money 😉. Australia is in Sahara Desert latitudes.

Hmmmm...zonal pricing? That would help Scotland regenerate and bring employment. Why don't those woke wallies in the SNP in Holyrood stop obsessing over gender ideology and concentrate on industrial and energy policy?
