Gas peaker plants solve the problem, with no additional costs.

We don't have to get carbon production to zero. If we run the gas plants even as much as 10% of the time for no-sun-no-wind-flat-batteries conditions, you've still cut 90% of carbon emissions.

At that point it would be much cheaper to look elsewhere for more improvements. There's no need to invent a reason for massive new energy infrastructure. The gas plants already exist; no exotic solutions are required to give 100% continuous power supply.

Europe can not continue to rely on natural gas and fossil fuels for the next 20-30 years, nor will the climate goals be reached if power consumption and thus gas consumption are increased.

Gas peaker plants are also not cheap. People think they are cheap when looking at the theoretical cost, but having energy plants in stand-by mode costs a lot of money. Generally those are paid by either taxes or as part of the grid connection cost because governments will pay a lot of money to have grid stability. In theory we could remove those subsidizes and let the market pay to have grid stability, but no governments in Europe do this.

Europe also do not have any easy access to natural gas. The only country would be Norway. Being energy self-sufficient is important from a geopolitical perspective and I doubt anyone is unaware about the strong connection between current wars and fossil fuels. Nuclear fuel can be both mined and constructed in EU, the fuel is much less sensitive to geopolitical events, and the diversity in the nuclear fuel production chain is fairly good. Countries can much easier store up decades worth of fuel.

So you are going to have nuclear plants in standby? Then I have a bridge to sell you.
Re:Georgia nuclear plant begins splitting atoms for first time by belorn on Tuesday March 07, 2023 @05:27PM (#35062169)
Of course not, but is that question even asked in good faith? Are you not aware that the European grid is made out of multiple different technologies each with a different benefits and drawbacks?

Right now the most important aspect of the grid is not price, it is the reduction of fossil fuel dependency. It is not sustainable to use fossil fuels in the short run and it is definitively not sustainable in the long run. Countries need to invest and start building replacement for existing fossil fuel power plants, and they also need at the same time increase capacity. On top of that we also need to start replace and remove part of the hydro energy production in order to prevent several extinctions.

It is also not morally or economically sensible to continue spend subsidizes on fossil fuel plants. A minimum requirement for government subsidizes should be zero green house emissions and geopolitical self-sufficient within the borders of EU.

The problem with nuclear is that every dollar spent on nuclear could have displaced more fossil energy if invested in renewables. Any investment in nuclear prolongs the climate crisis.

The next problem nuclear faces is that the CAPEX heavy economic model requires them to run at 100% all the time, they used to be able to do that but renewables undercut them wildly.

Now you start to lower the capacity factor of the nuclear plants, which has now gone from $0.15/kWh to ~$0.3/kWh when operating at 50% capacity factor.

Who even wants electricity for that price? It's beyond what we today call an "energy crisis". This is locked in until that nuclear plant has paid of its initial investment after 40 years.

Every dollar spent on nuclear, or every dollar spent on gratuitous nuclear regulation? Renewables kill many more people and render far more land uninhabitable per kWh generated; if we normalized our safety requirements then we'd turn off more coal more quickly by going to nuclear.

Germany switched their policy away from nuclear and the result is they've spent more money (just look at the cost of the required grid upgrades alone from their renewable programme) and generated more CO2 (with coal plants being kept open past planned shutdowns, and in some cases even restarted).

There's plenty of space for renewables in the mix, but opposing nuclear doesn't mean more money gets spent on renewables and certainly doesn't mean more emission reduction; quite the opposite.

Ehh what. None of this is true.

The great thing is that we are in 2023 and not 15 years ago. Germany spearheaded the renewable transition with the subsidies and huge buildout they enbaled. Today we can utilize the fruits of that.

We make choices based on the options today, not past results.

> There's plenty of space for renewables in the mix, but opposing nuclear doesn't mean more money gets spent on renewables and certainly doesn't mean more emission reduction; quite the opposite.

Then the money gets spent on other economic activity, rather than siphoning state subsidies to a pet nuclear project.

The market should deploy the cheapest grid possible that can produce emission free energy. We should be using those market forces.

The problem that we have is that governments steps in to subsidize grid stability. Industries and citizens in general do no accept a government that allows for black outs, and they also do not accept a government that allow the energy price to reach the natural market price when supply is very low and demand is high.

A second major problem is that if cheap renewables can produce 90% of supply and we need to 10% of expensive storage to meet demand, the cost that customers will have to bear is as if 100% of the produced energy came from the expensive storage. This make it very expensive to customers to have a combination of very cheap and very expensive energy production.

And finally, EU law dictate that if a country has surplus energy production then they must sell it to countries that has a deficit in energy production. This makes grid stability an EU wide issue, and even if a single country has an very stable production they will still share the high costs of energy unstable countries.

All of it create a market where the cost of $/kWh of energy created within a country is just loosely connected by the real price that customers pay. This winter demonstrated that multiple times, and all the governments subsidizes and price roofs illustrated how ready governments are to pay when the real cost of grid stability lands.

We are. Marginal cost + paying for CO2.

https://en.wikipedia.org/wiki/European_Union_Emissions_Tradi...

You are missing the time factor. Supplying 90% means that a vast majority of time they fulfill 100% and the expensive storage is not required. All based on the marginal price market Europe employs.

The storage would still be needed, but it is not the marginal cost and maybe storage is not the right path? Maybe it is sector coupling? Maybe it is demand response from hydrogen production for industrial use? Maybe it is not charging most cars for a couple of days?

As with all capitalistic systems a holistic organic approach will emerge. If it is not good enough adjust the market conditions. Sweden is already putting most stabilization services on an open market, with the goal to trade all day-ahead like power.

Pulling out a five-year plan of having nuclear solve it in 20 years will only lead to pain.

Re:Georgia nuclear plant begins splitting atoms for first time by belorn on Wednesday March 08, 2023 @10:18AM (#35070017)
If that were true then we wouldn't see large wind/solar regions where the average cost during this winter were at $0.3/kWh or above. Wind and solar did contribute a lot, but it was quite rare that they hit 100%. Instead it was gas prices that controlled what the energy prices was. It was this fact that resulted in many country implementing a roof of how much profits those renewables could earn, redirecting those profits in order to pay the bill for more fossil fuels.

Sweden is a prime example of a country that is paying the cost of stabilizing the grid for the rest of the continent. They could have had one of the cheapest energy grid in EU thanks the the large stable production from nuclear and hydro, but because of how the EU system is setup the opposite occurred. The result is the highest inflation rate in EU coupled with a significant hit to the economy. Germany in contrast is using the profits they historically gained by using cheap natural gas from Russia and injected billions to their industry in the form of energy subsidizes, sheltering their economy from the same fate. Who cares if the energy prices reaches well above $1/kWh if the government foot the bill?

Massive subsidizes and huge difference between marginal cost and actually price is not a free market. There is nothing free about it.

No, decarbonize the grid the way France did it. Don’t follow Germany’s example.

It’s that simple.

Re:Georgia nuclear plant begins splitting atoms for first time by Gwypaas on Wednesday March 08, 2023 @05:14AM (#35067239)
The French example is amazing. A bunch of negative learning by doing and then the total boondoggle of Flamanville 3. Lets emulate.

Have a look at this crudely drawn graph to see the nuclear French cost over time with Flamanville 3 added as a cherry on top:

On the other hand Germany has gone from about zero to 50% renewables while spearheading the renewable market. Sure, personally I would prefer if they had closed fossil generation before nuclear, but Fukushima threw a wrench in that plan.

To not utilize the fruits of Germany's efforts today would be insane. We are making decisions 2023, not 2005.

Re:Georgia nuclear plant begins splitting atoms for first time by kgabis on Wednesday March 08, 2023 @05:46AM (#35067443)
What fruits? German co2 emissions per capital are similar to coal heavy Poland. Energiewende is a massive failure and a great example of politics screwing people and environment over.
Re:Georgia nuclear plant begins splitting atoms for first time by Gwypaas on Wednesday March 08, 2023 @06:17AM (#35067670)
Which is amazing considering that Germany has 2.8x the GDP per capita of Poland. As I said, I do not agree with phasing out nuclear before renewables.

Short of that transforming the electricity sector of Germany from all fossil and some nuclear to 50% renewables in 15 years is nothing short of incredible.

Add the current exponential growth in renewables to that, now when the cost side does not require subsidies anymore, and we have an incredible future ahead of us.

Or as wiki puts it, they choose after Fukushima to not use nuclear as a bridging technology.

> The key policy document outlining the Energiewende was published by the German government in September 2010, some six months before the Fukushima nuclear accident.[1] Legislative support was passed in September 2010. On 6 June 2011, following Fukushima, the government removed the use of nuclear power as a bridging technology as part of their policy.

Re:Georgia nuclear plant begins splitting atoms for first time by kgabis on Wednesday March 08, 2023 @07:26AM (#35068173)
Per capita per gdp it's 70% higher than France. Going 50% renewables was a huge undertaking but it's clear it wasn't the right thing to do considering this money could've been spent on building more nuclear. It's all about decarbonisation, not about increasing share of renewable energy. Climate doesn't care about your share of renewables. Another thing to consider is that this transistion was in large part built on gas imported from Russia which funded the current war in Ukraine. And I would argue that growth of renewables in Germany has largerly stalled, barely any new wind farms are added to the grid nowadays. More solar has been added in recent years but Germany is so far north that it doesn't make much sense to build solar there (esp. considering energy requirements for winter). Energiewende is a big failure and the faster Germans notice the better.
Re:Georgia nuclear plant begins splitting atoms for first time by Gwypaas on Wednesday March 08, 2023 @07:46AM (#35068327)
You are stuck in the mindset of a blank slate with Energiewende as one of the options ahead of you. That decision is done, you can not revert it. The cost is paid.

We are now in 2023. This is how the cost for solar PV and wind have transformed, since that decision.

https://www.lazard.com/media/451886/grphx_lcoe-09.png

We are at the end of that graph. The outlook is not 2009, it is 2023. In 2023 renewables are the only choice, economically. When we hit 70-90% penetration depending on country there will be new problems to solve, but we are extremely far from that.

The current large build-out is off-shore wind, since that has higher capacity factors. We will see to what percentage of penetration that brings us. Then some sprinkling of solar on top because it is essentially free.

Nuclear and renewables both compete for the slice of the energy market being the most inflexible cheapest power source. Renewables win that by a landslide. Now nuclear becomes load following, and that horrific investment became even worse.

Re:Georgia nuclear plant begins splitting atoms for first time by kgabis on Wednesday March 08, 2023 @07:51AM (#35068372)
LCOE doesn't account for storage, backup and grid costs, please don't use it as a go to indicator that renewables are cheap. How much offshore capacity was added in the last 3 years in Germany? Zero? Or am I mistaken?
Re:Georgia nuclear plant begins splitting atoms for first time by Gwypaas on Wednesday March 08, 2023 @08:14AM (#35068584)
Energy grids tend to converge to LCOE of the producers. Just look at the average prices before the current crisis haphazardly replacing Russian gas with alternatives. We are also talking about the 70-90% case here, for that case no storage is needed. That is the point.

A stupid solution, which is cheaper than nuclear, is simply burning hydrogen in turbines like todays peaker plants. We are not at the point where it is needed, so everyone is instead looking for smarter solution.

The European grid is interconnected. UK awarded contracts to add 7 GW @ 60% capacity factor = 4.2 GW average last summer.

Germany seems to have added ~500 MW in off-shore wind in the last three years, so with that generations capacity factor about 230 MW in average power.

Re:Georgia nuclear plant begins splitting atoms for first time by kgabis on Wednesday March 08, 2023 @09:25AM (#35069280)
It just doesn't make sense to only use LCOE for weather and season dependent sources of energy, of course you need storage if you don't want to burn gas/coal during Dunkelflaute. Just look at German grid and what's happening right now (614 gCO₂eq/kWh, mostly gas and coal). Meanwhile France is at 92g. Are you really proposing countries like Poland decarbonise like Germany instead of following France's example? Interconnected or not, you do need cheap and dependable energy and the only clean source of that is nuclear. Hydrogen is just a greenwashed natural gas. And 500MW in 3 years is quite far from being meaningful.

Not just wrong but backwards, we in fact need to REMOVE gigatons of carbon to avoid dangerous, possibly catastrophic warming of the planet.

Re:Georgia nuclear plant begins splitting atoms for first time by ianburrell on Tuesday March 07, 2023 @07:32PM (#35063536)
We do need to get carbon production to zero, and then negative. But first we need to lower carbon production. Gas peaker plants make a good intermediate step. We can work on renewable electricity. And then work on more renewables and storage to get rid of all carbon, and finally even more renewables and carbon capture.

I have heard that 3x normal load in renewables is enough for nearly all the time with storage for load-shifting during the day. That results in extra capacity most of the time which can be used for carbon capture, making hydrogen, and making legacy fuels.

And now instead of paying for the expense nuclear power plant, you have to pay:

- Pay for 3x the raw capacity of the plant in solar and wind because they never run at peak capacity

- Pay for the battery for storage

- Pay for the Gas power plant that will never be cost effective because running 10% of the time.

And you still emit more CO2 than a damn nuclear power plant.
