As i have said before on this sight the gov departments were informed of the proof of concept test 2016 for a multi turbine hall system yet bsa and most others are disinterested in using this system. why i cant say but the education of the bosses seams to get in the way their told to use my system will make issues to the turbine hall this is not correct

Wind and solar energy combined with battery storage are the future. They are safer, cleaner and cheaper than fossil fuels. Cheaper WINS !

This is very exciting technology.

you are wrong about the energy required by AI. Once SuperIntelligence is reached, the strength of the country will no longer lie in the individuals walking around and going to work, it will lie in the Computers that do the work.

Can we get a piece on how our wind based grid will balance. Alot of push back around this in the press and it would be good to get clarification on the details.

I am so pleased that I went totally off grid about 5 months ago

(1)These pumped storage systems in the past backed up Nuclear and coal, nuclear can not be turned off. Going forward they will be required to back up wind. Bearing in mind that when the wind speed doubles the o/p power from wind turbines trebles .My question to Kate is ,would a variable pump speed generator be a better solution? If the the wind blows harder then the PSU pumps harder and reservoirs fill faster. (2)The upper lakes can suffer from evaporation(although in the British climate this is often replenished).By putting floating solar on the reservoirs evaporation could be reduced substantially. Other advantages would be improved power density, reduced wave height. You could also look at sealing the reservoir to reduce water leakage. The goal, brining energy efficiency above 90%. and eliminating the need for curtailment on the grid.

Here in New Zealand, we are considering a giant pumped hydro scheme. 5 TWhr of storage to help solve our "dry year" problem that occurs every 5-10 years which greatly reduces our existing hydro output causing increased coal burning and 10-50 fold increase in spot prices . The lower lake is in fact a river (our largest by flow rate) and low cost electricity would be used, as and when available, to pump 800m uphill to a natural basin in the hills. Unfortunately, our new "right wing" government has canned further work on the project due to pressure from the existing generator companies(half state owned) that make a fortune when the dry year occurs.

Every country that has a high proportion of wind and solar has very high power prices. Why is that ?

Unless there is an energy storage system that no one is talking about, a country cannot run off wind and solar. We do not really have much in the way of geothermal and we are too dry a country to have hydro in any meaningful way other than tassie. You need base load or the house of cards comes crashing down. Our electricity network is dysfunctional to say the least. They proport that we have some advanced electricity market but all it has given us is some of the highest electricity prices in the world.

Excellent introduction but how complex is this NEM. No one takes responsibility and the politicians are left to play short term point scoring games. Makes me want to have Czar to approve and demand these interconnects be built and to timetables that meets community and industry needs. Perhaps we should be inviting the Chinese in to build HVDC and stop all this knuckle dragging from politicians.

I am planning to go off grid next year, so that I can be totally independent of the politically controlled power systems.

You sound like you know what you are talking about. Just one issue is solar, wind and batteries do not do the job. Other than this major flaw you are doing a good job. (Waste of time)

Awesome guest! So knowledgeable and enthusiastic.

I saw a video that said high peaker prices set the total price for Australian grid electricity. Does that mean nuclear electricity prices also peak as the South Australian electricity prices have recently extremely high for those without rooftop PV and home batteries.??

Great video! Feel like I learned something. Would love a bit less editing, more raw, uncut footage.

That’s deep to think about… Peak versus non-peak electricity usage rates on the same 1 kWh of energy varying in cost

The amount of storage capcity to offset renewables' intermittency is not at all feasible, the required capacity is so large in the order of thousands of gigawatt hours. Storage is useful and does valuable work, but just to assist in grid stability requires a capacity that is only required because of the second and third rate generators we have connected to our grid, wind and solar respectively. In other words the expensive, contrary to government's claim, renewables require even more money from the electricity bills to try and keep the grid stable, when is this going to end? Even then we cannot say we will have a reliable grid as weather is so variable. Government policy on energy has been dreadful for decades and bring us to the current fragile grid we have now. They say renewables are more reliable and secure because we do not rely on foreign countries for our fuel or power yet expand interconnectors! And we are sitting on vast amounts of shale gas and the government do all they can to stifle the existing North sea operations, is there any logic whatsoever? Coal capacity has declined purely because of government policy but subsidies are paid for bio fuel which even emits more CO2 per Mwatt hour than even coal, and they call that green. Fuel from logging in the Americas, further processing and transport and they think that doesn't count? Coal is one of the best and most economical ways of generating electrcity. All this because of the unproven hypothesis that CO2 is altering our weather. Indeed humanity during history prospered when the climate was warm and declined during the cold spells.

It's always the same in this country no one will build anything unless they are guaranteed a high return to cover the costs in say 5 to 10 years these last for a long time how about long term economics, With fixed price contracts for the build, with exemptions like the oil crisis etc.

I thoroughly enjoyed the presentation. The lady certainly knows the subject inside out. Her passion was infectious. There were times however I wasn't sure what language was being spoken. The jargon was confusing and off putting. The TLA'S, Three Letter Abbreviations, were everywhere. Cap and floor was popular, Capex, Devex also. So much was spoken, to me the amateur viewer, which went over my head. I thought the comments at the end resolved some of my confusion. Thank you.

With a few niche exceptions, long duration storage, as related to pumped Hydro, basically means up to a day or two of generation and cycled reasonably frequently to recoup capital investment. In terms of storage capacity it is likely that we would need the equivalent of something in the region of 5,000 Dinorwig facilities (~1.8GW/9GWh) to meet the expected energy storage requirement by 2050. PHS will be neither technically nor economically viable for this scale of storage.

16:00 So wrong. The battery prices are getting so cheap with more and more large scale mining coming online and massive demand from all other transportation sectors. Combine this with a couple for south north UHV lines in Europe and job is done. The tech is all there on all levels, it just needs time for companies to invest and get it build. The only hold up and price driver is dumb and ever changing policies on old ideas.

16:10 You can run the EU grid entirely on "Wind+Solar+Battery+UHV". Please analyse in depth what the Chinese have built!

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?

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

OMG so stoked for this!

Very insightful discussion!

It seems obvious that the great glen with Lock Ness and Lock Lochy is an ideal region for pumped storage. There are high hills north and south of the glen and the volume of Lough Ness is massive. The construction of reservoirs will be expensive and you will need specific topography and stable rock strata. High voltage dc power lines will be needed to conduct the power to where it is needed. If you want to rely on wind and solar you need pumped storage and nuclear.

Flow batteries can provide 6-10 hour storage and the Oxford Energy Super hub uses them in conjunction with lithium ion batteries to give grid stabilisation alongside energy storage. 40 MWh of Invinity Energy flow batteries have been seleced as one of six technologies by the government for the LoDES (long duration energy storage) Stream 1 demonstration project.

Pumped hydro storage is the best but limited in where it’s feasible. Possibly the next best, I suggest, is combining green hydrogen and atmospheric nitrogen to make ammonia, Amonia provides a cheap easy way to transport and store hydrogen. Hydrogen can be separated from the nitrogen of the amonia using fuel cells and then used as a clean combustible fuel. I need to do some research to find out the overall efficiency of this energy storage method.

"What's up guys" doesn't really come across as professional.

This background music is p1ssing me off. I'll probably end up deleting the rest of the videos.

FYI: Since the start of the war in Eastern Europe, EU law requires the gas storage tanks to be filled to 90% by November 1st. (So higher than the 80% Seb mentions). This year they were at 95% full by November 1st. This is about 100 bcm of gas storage, representing about one third of EU annual gas consumption.

Hi why do you think of EOS Energy ? And Z3 batteries ? Thanks

41:06 First nuclear fan, not gas power fan, what's wrong with this moderator? Why so desparate to drive up energy prices for German consumers and businesses? Should you stay in Brexznit UK and explain how Hinkley Point C drives up the energy costs for the rest of this century? How come he is in this business and not aware, how China, Hawaii and other places are reducing their energy costs?

If you want to make energy cheaper, why are you guys for nuclear power, considering the cost explosion of Hinkley Point C???

34:00 Now she is in lala-land! Batteries are so cheap, they will provide all the energy storage needed on every level, from the tiny earpiece to the scale of nuclear powerplants...

Lithium batteries are hopelessly uneconomic for long-term grid scale storage. For the cost of 4GWh of battery storage you could build a gas-fired power station that can supply 40GWh of energy per day, day after day, week after week. The government's own plan for a de-carbonised electricity grid accepts that gas-generation capacity will be required well beyond 2030.

Are the recently disused mines in the Selby area being consided for pumped storage hydro schemes?

More nuclear? Crazy!!! Hinkley Point C, over 15Cent per kWh production cost! Google it! How can a host like this be so grossly uninformed! Shocking!!!

30:00 We don't need these old powerplants, we need battery power plants to replace them ASAP.

25:00 Dynamic tariffs are coming in Germany, but they are not what we want/need. We need battery power plants, in order to make the grid much, much larger, much much more robust without expanding cables...

Co-location with hydrogen generation and batteries would be ways to burnish the bottom line. Hybrid business plans can be marked differences in profit streams.

Thanks, What you say is very interesting. I guess I have some homework

But northvolt was managed by T junk guys. They promised grade A for cars, but as usual nothing but vaporware...

None of her opinion is valid. Why? On vs off grid. On grid 100% RE costs 60 cents/kwh for a house, 90 for super charge. On demand is the problem. RE is NOT on demand. The overbuild for RE is 4x in RE resources (Tony Seba's RE u-curve), and 3.5x for battery (storage). Total ON grid costs are 7.5x more than X, the demand. On grid RE costs 5 c/kwh for resource and 3 for line, for a total of 8 for each part. 8 x 7.5=60. You end up with 4x over capacity to lower the battery costs to get the minimum costs (u-curve), all while having to pay all to not generate with no place to store it all. Off grid electricity is 1.5 cents/kwh, NOT like ON grid at 8 x 7.5 = 60. This is due to no inverters and remote locations that have better RE resources. There are no demand balance issues or line charges OFF grid...key factor. Fuel is 2x the source off grid with DC (no inverters), or 3 cents/kwh with NO line charges. 60/3 = 20 times MORE for ON grid vs Off grid. Game over for EVs...reality. The ideal fuel is Ethanol for many reasons, but all oil fuels, chemicals and plastics will be needed to end oil. New combustion tech will be 75% with combined cycle and 60% efficient at 50% to 100% of torque. Old ICE is 15% (Otto cycle) to 18% (Diesel) on average low loads. Diesels loaded are 35 to 42%. Turbines are 45%. Turbines with combined cycle are 63%. New combustion is 81:1 expansions with 3 stage intercooling, Isochoric combustion, near isothermal compression. All doable. 75% is doable. The CO2 is also captured in the secondary. EVs are a total waste of time and money. They will cost 10 to 30 times more for energy input, and purchase price is 1.5 to 2x more, if not 5x for cars like Lucid. As for CO2, RE fuels are 1% of the CO2 of gasoline. New combustion tech captures CO2 as part of the secondary combined cycle and thus is "free" as it were. It costs 40 cents/gallon to capture the need CO2 for 1 gallon of gasoline if pulled from air. That means nuclear fuel (e-gasoline) can be 6 cents/kwh retail.

Pumped hydro needs 40% more electricity to pump the water upto the top, than is can generate. Grid owners charge for transmitted electricity energy at upto 10 times the generation costs. Then charges to transmit the electricity energy away from the pumped hydro. My feed-in 5cents kWh vs my 50cents kWh grid supply. Grids are valued in the $TRILLIONS. Grid cashflow is in the $100sBILLIONS. Generation is in the $10sBILLIONS. But obviously grid economics is part of every commentators expertise. Happy days 😊😊😊😊😊😊

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. "

21:17 keypoint: "ever get cell manufacturing in europe? -- a lot of asian players in eastern europe are producing cells" great speaker! Lola Hughes@

One coming technology that I think the expert should be aware of and share as being a very strong contender, is geothermal energy storage by way of fracking technology like the US shale oil and gas methods which is being commercially deployed now in Texas and California and can be done cost effectively in 50% of the world and is cheaper than battery storage and can be scaled up to grid scale.
