Claim: Coal, Gas and Nuclear Plants are Struggling with the Heat of Global Warming

Guest essay by Eric Worrall

According to climate scientists Ethan Coffel and Justin Mankin, we need to replace coal, gas and nuclear plants with solar and wind, because they are less affected by the heat of global warming.

Guest post: How global warming is making power plants produce less electricity

15 February 2021  8:00

Dr Ethan Coffel, assistant professor and climate scientist at Syracuse University

Dr Justin Mankin, assistant professor and climate scientist at Dartmouth College

The coal, gas and nuclear power plants that generate mostof the world’s electricity have to be kept cool in order to function properly. However, this will be increasingly challenging as the world gets warmer.

Waste heat from these facilities is typically released into the atmosphere or nearby water sources. During heatwaves or droughts, excessive heat or a lack of water makes it much harder for plants to be kept cool. 

When this happens, the plants must be curbed, meaning electricity output is cut. This often comes just as electricity demand peaks due to people’s increasing reliance on air conditioning to keep cool.

In a new paper, published in Environmental Research Letters, we find that in a warming world, hundreds of additional power plants would need to be constructed in the coming decades simply to make up for this lost power.

However, this is not the only option. If nations instead focus on technologies such as solar and wind, which produce fewer emissions and are less impacted by hot weather, the electricity sector will be both less of a contributor to – and victim of – climate change.

The study predicts an 0.8-1.2% falloff per degree of global warming, so not exactly a pressing emergency.

What about global warming induced severe winter weather? Climate scientists have rushed to assure us the Northern Hemisphere’s deep freeze is not incompatible with global warming. But as Texas recently noticed, solar panels and wind turbines don’t work that well when they are covered with ice.

Perhaps in the warmer future climate scientists expect, when snowfalls and freezing rain are a thing of the past, it might be worth considering solar and wind. But so long as severe winter weather is a possibility, surely it makes more sense to hang on to reliable power generation systems, maybe beef up the cooling systems a little so they can handle more heat in Summer.

Wind and Solar Generating Facilities are Struggling with the Cold of Global Warming
Gas and Nuclear might have a few percent efficiency drop off with an additional degree of warming but Wind and Solar have a 50 – 100% drop off of production with snowfall and extended cold periods … Like WINTER

Like all other semiconductor devices, solar cells are sensitive to temperature. Increases in temperature reduce the bandgap of a semiconductor, thereby effecting most of the semiconductor material parameters. The decrease in the band gap of a semiconductor with increasing temperature can be viewed as increasing the energy of the electrons in the material. Lower energy is therefore needed to break the bond. In the bond model of a semiconductor bandgap, a reduction in the bond energy also reduces the bandgap. Therefore increasing the temperature reduces the bandgap.
In a solar cell, the parameter most affected by an increase in temperature is the open-circuit voltage. The impact of increasing temperature is shown in the figure below.

The open-circuit voltage decreases with temperature reducing panel output. Also inverteres used in wind and PV begin losing efficency at aroud 130 degrees F.

The warming we have seen has not come from fossil fuels. As this paper from Norway demonstrates, the warming from CO2 is minuscule.

The Influence of IR Absorption and Backscatter Radiation from CO2 on Air Temperature during Heating in a Simulated Earth/Atmosphere Experiment

So, what is causing the warming over the past few centuries if not humans? The answer to that question may very well be …. humans. It’s just the mechanism that is wrong. A new paper, Cheng et al 2021, shows the changes in ocean salinity over the past few decades correlates very well with warming. The paper tries to blame the salinity change on AGW but their argument is so bad it would qualify as “not even wrong”.

The real cause is likely a combination of natural cycles with human use of salt in farming, water treatment, road deicing, etc.

Hi Richard M, – “Salinity” is a term referring to soluble minerals, of which there are quite a few. NaCl (sodium chloride) is popularly referred to as “salt”; although Na & Cl ions are certainly involved in salinity they are so as a part of total salinity.

In farming fertilizer formulas commonly include “mineral salts” which are water soluble, although agronomy does not refer to these as salt since mineral salts are more than just NaCl. I think that when reading about “soil salinity” many reflect on the word root “saline” & then mentally associate what read with our everyday salt NaCl.

In Australia, a lot of the output of windfarms is reduced when the air temperature goes over 40degC. This is because they overheat.

These geniuses failed to take into account that utility-scale power plants (at least here in the US) use cooling towers for heat rejection to the atmosphere.

Cooling towers reject heat by evaporation, and the capacity is dependent almost entirely upon the moisture content of the ambient air, not the temperature.

I find it awfully hard to believe that a degree or two increase in the design dry-bulb temperature, if it even ever happens, will have any impact on the ability of cooling towers to reject heat.

In fact as the dry-bulb temperature of the ambient air increases (all other things equal) the ability of the ambient air to absorb moisture will increase.

After reactor 2 at the Swedish Ringhals nuclear power plant had been running at reduced capacity since Monday 30 July, it was closed down completely Tuesday afternoon.

The continued warm weather in Sweden has brought the sea water close to 25 degrees during recent days. To maintain cooling capacity at Ringhals’ production facilities, sea water is used for cooling of various systems and components in the process. The sea water used for cooling Ringhals 2 has now reached a temperature that makes it necessary to take the reactor out of operation.
– When the water becomes warmer, its cooling capacity is reduced and in order for us to keep the necessary cooling capacity for the various systems with a good safety margin, we now have to take Ringhals 2 out of operation, says Sven-Anders Andersson, Head of production at Ringhals.
Ringhals 3 and 4 are still producing normally, and Ringhals 1 is presently closed down for scheduled maintenance. Each reactor has a maximum permissible value for the sea water temperature. For Ringhals 2 it is 25 degrees.

Warm sea water in Finland reduces power from Loviisa nuclear plant
Finland’s Loviisa power plant, consisting of two reactors with a combined capacity of 1 gigawatt, had to reduce power by 170 megawatts on Wednesday as the sea water that is used to cool the reactors had become too warm, operator Fortum said.
Because of the very warm temperatures the Nordic region is currently experiencing, the sea water that is collected to cool the Loviisa reactors is warmer and the water released is also warmer, at 32 degrees Celsius on Wednesday.
Releasing hot water back to the sea after cooling the reactors could be a hazard and if it exceeds 34 degrees Fortum said the reactors must be shut down due to regulations.

Low River Water Could Cause Problems for German Coal Power Plants
German utility RWE warned energy markets this week that low water levels on the Rhine River may affect the delivery of hard coal to some of its plants, although no power production has yet been affected.
An October 17 Platts report quotes an RWE spokeswoman as saying on Monday, “Continued low river levels are increasingly a challenge for transporting the coal [by river barge from the ARA region].”
Plants that could be affected include Bergkamen, Gersteinwerk, and Westfalen.

One problem for plants caused by low water.

An other:

Nuclear power plant in Germany on verge of getting switched off due to heat wave
A nuclear power plant in northern Germany has come to the verge of being taken off the grid on Friday, a Lower Saxony state environment ministry spokesperson told Clean Energy Wire. The ministry on Thursday had said the Grohnde nuclear plant near Hannover would likely be taken offline, as high temperatures were excessively warming a river used for the plant’s cooling system, and should be started up again once the heat wave that has hit Germany and other European countries with unprecedented temperatures has abated. On Friday, the plant’s operator, Preussen Elektra had informed the ministry that water temperatures were not rising as quickly as expected. However, precautions for a possible shutdown were taken nonetheless, the operator said. The river Weser, into which the plant’s cooling water is discharged, is suffering low water levels and has warmed to above 26 degrees Celsius. Additional heat from the nuclear reactor could damage the river’s ecosystem, the ministry said.

Influence of cooling water temperature on the efficiency of a pressurized‐water reactor nuclear‐power plant
The main findings of the paper is that the impact of 1°C increase in temperature of the coolant extracted from environment is predicted to yield a decrease of ∼0.45 and ∼0.12% in the power output and the thermal efficiency of the pressurized-water reactor nuclear-power plant considered, respectively.

Texas needs to be the poster boy for the renewable reliability, and Texas also has many coal plants still operating. I see them every summer driving to Colorado on 287 and hundreds of windmills each side of the highway. Granted, on the hot days of summer that wind is blowing and helping with all the folks’ airconditioners that they didn’t use 50 or 60 years ago. Ditto for the hot sun panels.

But then comes winter! This storm is the best example so far for too much relaiance on the renewables that cannot store excess energy by some means or another.

If I controlled the grant money, I would require the clueless academicians to live using their idea of how cheap and effective and reliable the windmills and solar panels work. And also require them to drive pure electric vehicles, no hybrids. After a few weeks in the winter they would likely die, not just suffer and learn to build a fire.

Oh well, I can dream, huh?

“Texas needs to be the poster boy for the renewable reliability”

I think they just became the poster boy for unreliable electrical power in the form of windmills and solar.

Any sensible person can now see that windmills and industrial solar are not suited to providing baseline electrical power for the nation.

If the alarmists insist on trying to reduce CO2 output then nuclear power generation is the only viable option for them, and for the rest of us.

Windmills and industrial solar are deadends. They are niche power generation options The pubic should not have to subsidized these industries, they should succeed or fail on their own.

Texas had windmills producing 23 percent of their electrical power, and we see what happens when most of that becomes inoperable. A disaster ensues.

And we all thought Germany and California would be providing us this lesson about unreliable electricity generation. As they say, “Everything is Bigger in Texas!”

All refineries have more or less the same processes that run at the same temperatures. Northern refineries have small cooling towers, southern refineries have big cooling towers. I’ve worked in Texas and up north – no issues with temperatures in either place.

So (cough cough), if temperatures just happen to go up, make the cooling towers bigger. Crisis averted. Where is my honorarium for solving this world-shaking problem?

Northern refineries have small cooling towers, southern refineries have big cooling towers. 

A little bit of bit of a simplification but pretty much true.

Hundreds of power plant will have to be built because the get old.

I was a power plant engineer. All power plants struggle to keep on line in extreme weather. I can think of no exceptions.

One of the reasons nuke plants in the US produce more power is power uprates. Basically cooling system design margins are used. So on some days, the plant can only produce the original rated power.

Another misconception about steam plants is that they are massive. Only the output is massive.

Wind and solar require large footprints. Life cycle emissions are not lower. They may appear to be lower when college professors do they calculations based on ‘expected’ output. However, wind and solar never produce expected power. I expect zero to be produced.

So during the hypothetical period for temperature to increase, hundreds of steam plants will get built. Not a big problem.

Millions of wind and solar projects will need to be built. Not possible.

At some point the fall apart rate will exceed the build rate.

I sincerely admire how Eric kept his patience here.

What is concerning here is the obvious red herring: coal would be negatively and meaningfully affected by climate change, and solar/wind power not. This is not what good scientists will do. This is what policy advocates do.

I believe the assistant professors actually know a lot more on the topic than it looks like they do. They have just decided to emphasize possible engineering ‘challenges’ related to coal power.

Typically when it’s very hot in Texas it means a high pressure system is in place and means little to no wind. Wind doesn’t work when it’s very hot or very cold. Or when it’s very windy for that matter!

All excellent points!

There are lots of situations where windmills and solar don’t work.

No sensible person would make them the backbone of our electrical systems because they are obviously subject to fail at the worst times possible.

The alarmists are going to have to drop the promoting of windmills and solar. They now have an objective reason for doing so: Windmills and solar have caused a disaster in Texas.

And it is really the policy that has put Texas in this shape. Texas politicians have supported making their electrical grid 23 percent dependent on technologies that cannot be depended on at all times.

Like one Texan said on tv this morning, the Texas politicians who are clamoring for an investigation into how this disaster happened, are the very same ones who put this policy in place in the first place.

Windmills and industrial solar cannot be depended on. That’s the bottom line, and Texas politicians should take measures to up fossil fuel and nuclear generation to make up for this 23 percent deficit.

Don’t just add more windmills, that will just make things worse. I know that’s a really dumb suggestion, but you wait, some ignorant alarmist will suggest it.

French nuclear plant regularly shuts down due to warm water and low river levels… so too some German coal plant. There is more extreme (for the region) heat in Europe and more low river levels as a result.

These systems have margins on both sides, based on experiences If these margins are meaningless because of changes, the margins have to be changed and the systems to be adapted. But adapt to lower water levels is more difficult as to water temperature.

Sorry for wrong link; correction

I started that discussion yesterday here

There is a grain of truth….heat engines get less efficient as the ambient temperature increases.

but…humans have deployed power generation units from the Arctic North Slope to the deserts of Arabia…..pretty big temperature range there….

If the ranges don’t change, no problem 😀

Plant operators will do what humans have always done and adapt to the changes. Life will continue.

In most countries, power demand peaks in winter when it’s needed for heat.

Therefore warmer winters will REDUCE the generating capacity needed.

What a load of crap! These people will write anything! I don’t care what degrees they have or what their titles are, they aren’t scientists. They’re nothing more than dishonest hacks, and aren’t even very good at that!

I suggest the learned ‘assistent professors’ read up on elementary thermodynamics. If they have any idea what that is, which appears questionable.

Again with the evidence that degrees mean Bull Schist, More Schist and Piled higher and Deeper…

Solar panel efficiency is temperature dependent – the hotter the panel, the lower it’s conversion efficiency of photons into electron flow.

Notice in the above link the second chart on the page, at 0 degC the panel efficiency is 16% and at 50 deg C it is about 13.3%.

So yes, in a warmer climate cooling for the power plants reduces overall efficiency a teensy bit, but solar panels suffer losses in efficiency too with increasing temps!

And duh, a wind turbine’s efficiency has as one of the factors for the maths, the AIR DENSITY! Air density is considerably lower for higher temperature than low, so wind turbines also suffer a loss of efficiency for higher average air temperature!

Power = 0.5 x Swept Area x Air Density x Velocity^3″

How do idiots like this get degrees in the first place and how on earth do they get professorships??? There used to be a joke about so and so getting their degree in a Cracker Jack box – I don’t think it’s funny anymore….it appears to be widespread.

“Solar panel efficiency is temperature dependent – the hotter the panel, the lower it’s conversion efficiency of photons into electron flow.”

Yes, and solar panels don’t work at all when they are covered by snow.

If these 2 tossers just happened to be right, IF, then there’s a simple engineering solution. The trouble with climate tossers is that they have no idea how the real world works; just like too many politicians.

If what they claim had any merit don’t you think it would have shown up in any of many areas with a hot climate where fossil fuels are used to generate electricity?

What a moronic claim. Every source of energy has an optimum temperature for working, including solar panels: with the important difference, that solar devices efficiency is more impacted by high (surface) temperatures, than thermoelectrical power plants one. Also, where heat waves may see a reduction in wind speed (as typical of many sultry heat waves, in temperate and sub-tropical climates), the wind mills are impacted as well and out of any predictability. This claim is just political, not technical nor scientifical.

February 17, 2021 2:38 pm

This is an effective propaganda article. The people at whom it is aimed are not numbers people. Just wait. Someday you’ll be talking to someone about how thermal power is more reliable and they’ll say “yes but when the temperature goes up those power plants use more power just to keep cool’. The fact that the extra amount of energy needed is minuscule does not enter into it.
