World's first '#SandBattery' can store heat at 500C for months at a time. Could it work in Australia?

By technology reporter James Purtill
Mon 18 Jul 2022

Excerpt: "Polar Night Energy's chief executive officer Markku Ylönen said the entire battery could be built in "any steel workshop".

" 'It's really a typical #silo with nothing that special,' he said.

"To discharge the stored #ThermalEnergy, air is circulated through pipes in the sand where it's heated, then directed, to wherever it's needed.

"Right now, that's mostly heating homes, but it could also be used for high-temperature industrial processes, Mr Ylönen said."

Solar panels that fit on your balcony or deck are gaining traction in the US

By ISABELLA O’MALLEY
Updated 1:04 PM EDT, August 15, 2025

"When Terrence Dwyer received a knock on his door and a flyer for a solar panel system small enough to fit on his deck, he was quickly sold. Solar systems that plug into regular wall outlets have been popular in Europe for years and are gaining traction in the U.S. for their affordability and simple installation.

" 'We thought absolutely, let’s do this right away,' said Dwyer, who lives in Oakland, California.

"These small-scale solar systems could become attractive to more homeowners now that President Donald Trump’s sweeping budget-and-policy package will scrap residential rooftop solar tax credits and may shift interest to cheaper alternatives. Even before the GOP bill passed, manufacturers of the smaller systems known as plug-in or balcony solar were seeing increased demand and other positive signs such as a new Utah law streamlining regulations for homeowners to buy and install them. The systems about the size of a door haven’t been as widely adopted in the U.S. as in Europe because of lack of awareness, patchwork utility rules and limited availability.

"The $2,000 plug-in solar system installed on Dwyer’s backyard deck in March consists of two 400 watt panels, an inverter, a smart meter and a circuit breaker. It saves him around $35 per month on his power bill because he is consuming less energy from the grid, but he said reducing his carbon footprint was his primary motivation."

#French #NuclearPower production expected to be reduced on Wednesday

By Reuters
August 12, 2025

PARIS, Aug 12 (Reuters) - "Power production at France's #Bugey3 #nuclear reactor in the east of the country is expected to be reduced by 500 megawatts (MW) on Wednesday, data from operator #EDF showed on Tuesday, as high river temperatures reduce the plant's ability to intake cooling water.

"A #heatwave throughout #France has led to multiple warnings of power reductions at a number of #NuclearPlants, particularly on the #RhoneRiver in the east and the #GaronneRiver in the west.

"The #Bugey 3 reactor has a maximum capacity of 910 MW, which will be reduced to 410 MW from 2:30 p.m. (1230 GMT) to midnight on Wednesday as the reactor is required to meet environmental safety measures, EDF's data showed.

"The high water temperature warnings for the #SaintAlban plant - down river of the Bugey site - and the #Golfech site in the west were moved to August 14, but restrictions have not yet been issued.
Average temperatures in the country are expected to continue to peak throughout the week, reaching a high of 28.5 degrees Celsius (83.3°F) on Saturday, LSEG data showed.

"#NuclearPower accounts for about 70% of total French power consumption annually, but August is the main holiday season throughout the country and electricity demand is often limited."

#Jellyfish Shut Four French #NuclearReactors as #HeatWave Builds

By Eamon Farhat
August 11, 2025

"#Electricite de France SA [#EDF] was forced to shut four #AtomicReactors after a swarm of jellyfish clogged up filter drums at its #Gravelines power plant.

"The 'massive and unforeseen' [um, not if you read my posts -- very much FORESEEN] presence of jellyfish in the filter drums of pumping stations closed four out of six reactors at Gravelines on the north coast of France, EDF said in a statement on Monday. Pumping stations for coastal #NuclearPlants usually draw in sea water for cooling, sometimes exposing them to marine life.

"A #MarineHeatWave is intensifying off the west coast of France, with unusually warm waters in the English Channel near Gravelines, data from #Copernicus Marine Service show. Jellyfish populations can 'bloom' at such times, and France has closed several beaches in recent weeks due to invasions of the eight-legged molluscs, according reports compiled by the beach information app Meduseo."

Invasion of #jellyfish, heat, water too hot: #GlobalWarming threatens the functioning of #NuclearPowerPlants

Several reactors are regularly forced to stop to protect river #biodiversity. While cuts in periods of high heat still have a very limited impact on supply, electrification of uses and #ClimateChange could make a difference.

Marie Toulgoat , Published 11 August 2025

"When nature paralyses the French nuclear park. Four units of the Gravelines nuclear power plant (northern) are at a standstill on Monday 11 August due to the 'mass and unforeseeable presence of jellyfish; at the water pumping stations used for the cooling of the reactors, EDF announced.

"These automatic stops of units 2, 3, 4 and 6 'have had no consequences on the safety of the installations, the safety of personnel or on the environment', #EDF assures on its site. The plant is thus temporarily completely shut down, as its other two production units 1 and 5 are currently under maintenance.

"On Sunday, 29 June, no steam volutes escaped from the chimneys of the Gulf nuclear power plant (Tarn-et-Garonne). Due to the intense #HeatWave in #France, the reactor in operation at the site was shut down. In the middle of the summer of 2024, the nuclear power plant had already been forced to reduce its production."

[Paywall] From 2021: Increase in frequency of nuclear power outages due to changing climate

by Ali Ahmad

Nature Energy volume 6, pages 755–762 (2021)

Abstract:

"Climate-related changes have already affected operating conditions for different types of energy system, in particular power plants. With more than three decades of data on changing climate, we are now in a position to empirically assess the impact of #ClimateChange on power plant operations. Such empirical assessments can provide an additional measure of the resilience of power plants going forward. Here I analyse climate-linked outages in #NuclearPowerPlants over the past three decades. My assessment shows that the average frequency of climate-induced disruptions has dramatically increased from 0.2 outage per reactor-year in the 1990s to 1.5 in the past decade. Based on the projections for adopted climate scenarios, the average annual energy loss of the global nuclear fleet is estimated to range between 0.8% and 1.4% in the mid-term (2046–2065) and 1.4% and 2.4% in the long term (2081–2100)."

NatureIncrease in frequency of nuclear power outages due to changing climate - Nature EnergyThe impact of extreme weather events driven by climate change is increasingly disrupting energy assets and services. Using operational data of nuclear reactors, Ali Ahmad identifies how disruptions in nuclear power production have increased over the years with increasing temperature anomalies, and projects future loss of output.

We’re having a #heatwave...

And #NuclearPower can’t cope. Worse still, it’s actually a liability under ever more extreme climate conditions, write Karl Grossman and Harvey Wasserman

Posted on July 27, 2025, by #BeyondNuclear

"At the core of the latest attempted 'renaissance' of nuclear power is the big lie that #AtomicReactors are an answer to #GlobalWarming. In fact, they are significant sources of heat.

"There are more than 400 nuclear power plants in the world today that fission atoms at 300 degrees Centigrade, (572 degrees Fahrenheit). More are under construction or proposed. As the International Atomic Energy Agency states, 'water-cooled reactors offer heat up to 300 degrees Celsius. These types of reactors include pressurized water reactors (PWRs), boiling-water reactors (BWRs), pressurized heavy-water reactors, and light-water-cooled graphite-moderated reactors (LWGRs).'

"Some heat is absorbed in the water—drawn from water bodies—used to cool these nuclear power plants and then returned, still with considerable heat, to #rivers or #seas.

"The heatwave going on in recent weeks in Europe, in combination with this discharge of heated water from nuclear plants, has caused #NuclearPlants there to shut down.

"Consider these headlines from recent days:

" '#France and #Switzerland shut down nuclear power plants amid scorching heatwave,' was the July 3rd headline on Euronews. As the piece explained: “To cool down, nuclear power plants pump water from local rivers or the sea, which they then release back into water bodies at a high temperature. However, Europe’s ongoing heatwave means that the water pumped by nuclear sites is already very hot, impacting the ability of nuclear plants to use it to cool down. On top of this, nuclear sites run the risk of posing a dangerous threat to local #biodiversity, by releasing water which is too hot into rivers and seas.'

"A New York Times article, also dated July 3rd, related how in Europe, 'operators shut down one of the two reactors at the #Golfech nuclear power plant in southern #France after forecasts that the #GaronneRiver, from which it draws water and then discharges it after it is used in the plant as coolant, 'could top…82 degrees Fahrenheit.' The Times continued: 'The #Beznau Nuclear Power Plant in #Switzerland, built along the #AareRiver followed suit, shutting down one of its reactors on Tuesday and the other on Wednesday.' "

#Trump’s #BigBeautifulBill Will Destroy America’s #Climate Progress

The president’s signature piece of legislation is torching #GreenEnergy initiatives that were helping red states. #Republicans don’t care

by Thor Benson, June 29, 2025

"The United States is not where it should be when it comes to the transition to renewable energy. Ask any climate scientist or reputable energy expert, and they’ll tell you we’re significantly behind schedule if we’re hoping to avoid the most catastrophic effects of climate change. The Inflation Reduction Act (IRA), which Joe Biden’s administration got passed in 2022, was meant to help speed up that transition and get the country on the right track. Now, it’s under attack.
President Donald Trump’s administration has been working to undo any policies that would help the world avoid a climate catastrophe, and it is now trying to use the so-called 'Big Beautiful Bill' to repeal most of the climate-focused initiatives contained in the IRA. Trump’s signature legislation is caught up in the Senate after the House passed it last month, so it’s not entirely clear what the final draft will contain, but experts agree that these #climate provisions are clearly on the chopping block.

"The latest version of the bill would be particularly catastrophic for #wind and #solar. Republicans not only want to significantly cut #TaxCredits for these #CleanEnergy projects, they wants impose new taxes on them for the first time. Wind and solar projects completed after 2027, for instance, will be taxed unless they can prove no #ChineseComponents were used.

" 'They’re proposing an outright massacre with punishing new taxes on these industries that happen to be the cheapest and easiest ways to get new energy on the grid,' Sen. Ron Wyden (D-Ore.) wrote in a statement Saturday. 'If this becomes law, it will be a shocking act of economic self-sabotage.' "

#Carbon14: Another underestimated danger from #nuclear reactors

"There are a number of radionuclides released from nuclear energy facilities. This paper highlights carbon-14 for a number of reasons:

- Carbon-14 is radioactive and is released into air as #methane and #CO2

- Before 2010, carbon-14 releases from nuclear reactors were virtually ignored in the United States. Today only estimates are required and only under certain restrictive circumstances.

- There is no good accounting of releases to date, so its impact on our health, our children’s health, and that of our
#environment remains unknown, yet environmental measurement is possible, but can be challenging under certain
conditions.

- Carbon-14 has a half-life of over 5700 years and the element carbon is a basic building block for life on earth. Therefore, “it constitutes a potential health hazard, whose additional production by #anthropogenic sources of today will result in an increased #radiation exposure to many future generations.”

- Like #tritium, it can collect in the tissues of the fetus at twice the concentration of the tissues in the mother, pointing to its
disproportionate impact on the most vulnerable human lifecycle: the developing child.

The element carbon is found in all organic substances. Carbon is also a primary constituent of #GreenhouseGases that are responsible for #ClimateChange, such as carbon dioxide (CO2) and methane (#CH4). Carbon-14 (c-14) is a radioactive form of
carbon that occurs in nature and is also newly formed in nuclear power processes.

"Carbon-14 is a health concern because it is released from #NuclearPower facilities as radioactive carbon dioxide and methane, traveling readily in the local and global environment.

"Over time, carbon-14 becomes part of organic material including food, and has a half-life of approximately 5,730 years, decaying by a type of radioactive particle called a beta. Its hazardous life is 10-20 times its half-life, meaning that harmful exposure to man-made carbon-14 can last for hundreds of generations. The radioactive carbon forms as a byproduct of fissioning of uranium fuel, through a process called activation. The final step is a chemical reaction between carbon-14 and oxygen or hydrogen, which forms methane or carbon dioxide. The radioactive carbon-14 formed by this process is brand new and would not exist without nuclear fission.

"During its long hazardous life, carbon-14 could be responsible for gross physical or
mental defects, stillbirths and childhood deaths, embryonic and neonatal deaths into the many millions over the life of the isotope.

"These millions could be underestimated five times or more. Carbon-14 could also be responsible for #leukemia, bone and other #cancers."

We Work The Black Seam

"This place has changed for good
Your economic theory said it would

It's hard for us to understand
We can't give up our jobs the way we should

Our blood has stained the #coal
We tunneled deep inside the nations soul

We matter more than pounds and pence
Your economic theory makes no sense

One day in a #nuclear age
They may understand our rage
They build machines that they can't control
And bury the waste in a great big hole

Power was to become cheap and clean
Grimey faces were never seen
Deadly for 12,000 years
Is #Carbon14

We work the black seam together
We work the black seam together

The seam lies underground
Three million years of pressure packed it down

We walk through ancient forest lands
And light a thousand cities with our hands

Your dark satanic mills
Have made redundant all our mining skills

You can't exchange a six-inch band
For all the poisoned streams in cumberland

One day in a nuclear age
They may understand our rage
They build machines that they can't control
And bury the waste in a great big hole

Power was to become cheap and clean
Grimey faces were never seen
Deadly for 12,000 years
Is carbon 14

We work the black seam together
We work the black seam together

And should the children weep
The turning world will sing their souls to sleep

When you have sunk without a trace
The universe will suck me into place

One day in a nuclear age
They may understand our rage
They build machines that they can't control
And bury the waste in a great big hole

Power was to become cheap and clean
Grimey faces were never seen
Deadly for 12,000 years
Is carbon 14

We work the black seam together
We work the black seam together
We work the black seam together"

So, I made an offhand comment to the specialty veterinarian who was wondering why our middle-aged kitty was having thyroid issues at such a young age. I said, "Who knows what she was exposed to in #SouthCarolina." And the vet nodded her head. Turns out, kitty may have been exposed to radiation at a young age -- which caused her thyroid to be initially hypo, then hyper! And may have caused some of her birth "defects" -- like short legs. Poor kitty. And if this is happening to housecats, imagine what it's doing to wildlife and humans!

#Greenland and #Iceland saw #RecordHeat in May. What does that mean for the world?

By ISABELLA O’MALLEY
Updated 1:42 PM EDT, June 11, 2025

"Human-caused #ClimateChange boosted Iceland and Greenland ’s temperatures by several degrees during a record-setting May #heatwave, raising concerns about the far-reaching implications melting #ArcticIce has for weather around the world, scientists said in an analysis released Wednesday.

"The Greenland ice sheet melted many times faster than normal during the heat wave, according to the analysis by World Weather Attribution, with at least two communities seeing record temperatures for May. Parts of Iceland saw temperatures more than 10°C (18 °F) above average, and the country set a record for its warmest temperature in May when Egilsstadir Airport hit 26.6°C (79.9 F) on May 15.

"The findings come as global leaders put more focus on Greenland, a semi-autonomous territory of Denmark, following U.S. President Donald Trump’s comments that he would like to annex the mineral-rich island.

"Burning #FossilFuels for electricity and transportation releases pollutants such as carbon dioxide that cause the planet to warm unnaturally fast. The Arctic is one of the fastest-warming places on Earth.

"Even in today’s climate, the occurrence of such a strong heat wave in the region is relatively rare, with a 1% chance of occurring in a year, the analysis said. But without human-caused climate change, such an event would be “basically impossible,” said Friederike Otto, associate professor of climate science at Imperial College London, one of the report’s authors.

"The extreme heat was 40 times more likely compared to the pre-industrial climate.

Global impacts from a melting Arctic

"Otto said this extreme weather event affects the world.

"As the Greenland ice sheet melts, it releases massive amounts of fresh water into the salty oceans. Scientists say this could slow down the Atlantic Meridional Overturning Circulation [#AMOC], an ocean current that circulates water from the Gulf of Mexico across the Atlantic Ocean to Europe and then the Arctic.

"Such a slowdown could disturb global climate and weather patterns.

“The nature of weather in the Northern Hemisphere is directly tied to what’s happening in the Arctic, because that ice floor basically at the bottom of the atmosphere helps determine the weather patterns that we get,” said Waleed Abdalati, who heads an environmental sciences institute at the University of Colorado Boulder. He was not involved in the WWA analysis.

"The Greenland ice sheet and other ice covering the Arctic can influence where and when wind blows, how much water content the wind has and whether precipitation falls as rain or snow.

"Most of the melting of the Greenland ice sheet happens in June, July and August. The May heat wave means there will be a longer melting season this year.

"Melting ice sheets and glaciers also contribute to #SeaLevelRise that is threatening to flood coastlines globally and inundate low-lying island nations in the Pacific Ocean.

"#Indigenous communities in Greenland are increasingly encountering dangerous travel conditions as sea ice that was once constantly frozen begins to thaw. Access to traditional hunting locations are lost, and sled dogs can no longer travel the same routes. Thawing #permafrost can destabilize buildings and increases the risk of #landslides and #tsunamis caused by landslides."
