The makers say: ‘To charge the battery, we take CO2 at near atmospheric temperature and pressure and we compress it. The heat that is generated during compression is stored. When we exchange the thermal energy with the atmosphere, the CO2 gas becomes liquid.

To generate and dispatch electricity, the liquid CO2 is heated up and converted back into a gas that powers a turbine, which generates power. The CO2 gas is always contained and the entire system is sealed. We don’t use any exotic materials.’

Italian startup Energy Dome, maker of the world’s first CO2 battery, is officially entering the US market, says Electrek.

Energy Dome’s battery uses carbon dioxide to store energy from wind and solar on the grid.

They’ve had coal, gas and oil filling that requirement for many decades. But now they scratch their heads and look for viable alternatives, with nothing of note to show for their effort. Climate obsessions like the ‘net zero’ illusion can do strange things to people’s ability to think rationally. Throwing away something vital without a suitable replacement is asking for trouble.

If the transition to renewables is to succeed, we will need a viable means of storing surplus heat and electricity, says TechXplore.

Globe spoke to experts from ETH Zurich about the promising technologies that could help us reach net zero.

Switzerland aims to transition to a net-zero energy system by 2050. To meet this goal, it will need to replace fossil fuels with renewables.

They admit so-called green energy has a big problem, namely intermittency. Getting rid of reliable electricity generation from power stations creates it, but that’s what the likes of the climate-obsessed BBC constantly advocate. The sand idea may have some uses, but it’s admitted that ‘The efficiency falls dramatically when the sand is used to just return power to the electricity grid’. No, the big problem will remain.
– – –
Finnish researchers have installed the world’s first fully working “sand battery” which can store green power for months at a time, says BBC News.

The developers say this could solve the problem of year-round supply, a major issue for green energy.

Using low-grade sand, the device is charged up with heat made from cheap electricity from solar or wind.

The sand stores the heat at around 500C, which can then warm homes in winter when energy is more expensive.

The COP 26 climate jamboree has been and gone, and the BBC looks at some of the energy numbers as the UK government pursues its net zero obsession. One obvious and increasing problem is the erratic deficiency of wind and solar power at various times in every 24-hour period, requiring either massive, expensive energy storage capacity or acceptance of power gaps once gas power stations are removed from the system, or most likely both. Complaining about expensive gas, only to propose something yet more costly which doesn’t even generate its own power, lacks economic or any other sense. Nuclear is jogging along in the background but won’t be centre stage any time soon, if ever.

The UK has committed to reduce its greenhouse-gas emissions to net zero by 2050, says BBC News.

Net zero is the point at which the country is taking as much of these climate-changing gases out of the atmosphere as it is putting in.

As part of this promise, the government has a target to cut emissions by 78% by 2035, compared with 1990 levels.

Looks like yet another visit to cloud cuckoo land for climate alarmists fretting about trace gases in the atmosphere. They’re creating a massive problem with insistence on an EV-only future and now cast around frantically for solutions, as the clock ticks to chaos. Let’s try a food analogy: juggling oranges doesn’t give you more oranges.

Transportation is the single biggest source of greenhouse gas emissions in the United States, accounting for about a third of all emissions, says TechXplore.

We could quickly lower those emissions by electrifying vehicles, but there’s just one hitch: we don’t currently generate enough power.

“If all transportation goes electric, we are effectively doubling demand,” said Matthias Preindl, an EV expert at Columbia Engineering. “And the grid isn’t built to withstand that.”

The huge growth of the UK’s solar and wind could lead to an excess amount of electricity by 2030, says Energy Live News.

That’s according to a new study that suggests a huge amount of energy could go to waste if this expansion of renewable energy sources is not paired with a similar rise in the installation of energy storage technologies.

Consultancy LCP justified its forecast on the basis that Britain’s grid operates on a supply and demand process.

If they’re already struggling to get enough lithium when EVs have only a small market presence, where are the supplies for the massive planned EV expansion supposed to come from, and at what cost in already expensive machines? Mining operations don’t spring up overnight, and time is short if supply is to meet the expected demand from the manufacturers.

As the price of lithium has skyrocketed over 400% in the past year, the demand for lithium-ion batteries appears more intense than ever, says AG Metal Miner @ OilPrice.com.

Lithium has earned the ‘white petroleum’ label due to its dramatic need for supplies from the rise of battery giga-factories, electric vehicles, powerwalls and energy storage businesses.

Battery makers including Tesla, Panasonic and LG Chem, have to budget for the rising cost of lithium. Batteries that go into electric cars require lithium. More battery makers will need to expand production to keep up with demand from electric cars.

‘Four storage solutions to help Britain keep the lights on deep into the future’ says the paper’s sub-heading. But given the puny nature of their suggestions, that looks to be about all they could hope to do. What about actual reliable power for heating, transport, industry, commerce, hospitals, shops, services etc.?

Soaring energy bills rooted in a global gas supply crunch have focused minds on the age-old problem: how can we better store power? says The Guardian.

Attention has turned to the closure of the Rough gas storage facility in the North Sea in 2017, which left the UK with only enough storage to meet the demand of four to five winter days.

But while gas is being phased out, Britain’s growing reliance on renewables, such as offshore wind and solar, does not solve the problem of intermittency – what happens when the wind does not blow or the sun does not shine.

The key to securing enough affordable, low-carbon energy is more storage to make the most of the renewable energy available. A storage boom has been forecast over the coming decade as governments race to meet their climate targets.

Their four suggestions:
— ‘Gravity’ storage
— Concentrated solar power storage [see below]
— Green hydrogen
— ‘Cryogenic’ batteries

If anyone finds any or all of these a convincing and/or ‘affordable’ alternative to existing fuels as a storage medium, please explain why.

UPDATE 10/1/22, 7PM (UK)
The Concentrated solar power storage project cited by the Guardian (Crescent Dunes) as an example to follow has already been wound up!

Fracking: note the deep shaft


The chances of the UK government listening to anybody other than climate obsessives on energy matters are about zero. Most of the opposition parties are even more addicted to the notion of climate being determined by the level of trace gases in the atmosphere, with wildly unrealistic policies to match.

London, 29 December – Net Zero Watch has called on Boris Johnson to declare an energy emergency and introduce radical policy reforms in order to prevent the energy cost crisis turning into an economic and social disaster.

The call comes as fears grow over a devastating energy cost and energy security crisis, with spiralling prices hitting households and businesses hard, and warnings that energy bills could double or even treble next year.

It is reported that Boris Johnson is considering to hand out £20 billion of taxpayers’ money to energy suppliers who are threatening to double or treble energy costs.

The report says these batteries are not covered by the Control of Major Accident Hazards regulations, meaning they’re now popping up all over the place, sometimes near people’s homes. Any problems however serious have to be faced by the local fire services. Lithium-ion storage battery fires are far from rare, as well as notoriously violent, fiercely hot and difficult to deal with.

The first thing you notice is the noise – a strange, low-octave hum growing louder as you approach across the fields, says the Mail on Sunday (via The GWPF).

It’s coming from a group of bland metal cabins sitting on land that was once used to grow wheat and barley.

Yet these new agricultural buildings are nothing to do with food production. Instead, they contain huge batteries storing electricity for the National Grid – a new form of crop for farmers scrambling to cash in on the ‘green’ energy revolution.

And, according to a troubling new report from leading physicists, these vast batteries amount to electrical bombs with the force of many hundreds of tons of TNT.

That’s the headline, but is ‘novel’ its only merit? Buoyant Energy is described as promising but then, aren’t they all? Energy storage on a meaningful scale seems as far away as ever, having rejected the obvious ones: coal, oil, gas and sometimes even nuclear.

What do pipes and anchors have to do with storing energy? More than you might think, suggests TechXplore.

A new IIASA-led study explored the potential of a lesser known, but promising sustainable energy storage system called Buoyancy Energy Storage.

There is general consensus that renewable energy sources will play an important role in ensuring a healthier and more sustainable future for the planet and its people, and many countries are indeed already seeing such technologies displacing “dirty” fossil fuels in the power sector in an effort to lower emissions. [Talkshop comment – CO2 emissions have absolutely nothing to do with dirt].

The biggest problem with renewable energy sources, however, is that power supply is intermittent, meaning that the energy output at any given time does not necessarily meet the demand at that time.

Like ‘free beer tomorrow’, projects such as this one may sound good to some, but does the promised tomorrow ever arrive? So far, no. Not even close. And equating so-called ‘clean tech’ with the climate is yet another obviously absurd media fantasy. Solving the issue by 2030 is the target — good luck with that. Of course gas, coal and oil are their own energy storage, but don’t mention those any more.

A major project aims to overcome a barrier to electricity grids wholly supplied by renewable energy, says BBC News.

Output from wind turbines varies because wind speeds fluctuate; output from solar cells changes according to cloud cover and other factors [Talkshop comment – such as 50% darkness per year].

This is called variability, and overcoming it is crucial for increasing the share of renewables on the grid.

Another day, another battery ‘breakthrough’, you may be thinking. The idea being to make the battery part of the device itself, rather than being inserted into it. Tesla has already designed its own version of the idea.
– – –
Researchers from Chalmers University of Technology have produced a structural battery that performs ten times better than all previous versions, says TechXplore.

It contains carbon fiber that serves simultaneously as an electrode, conductor, and load-bearing material.

Their latest research breakthrough paves the way for essentially ‘massless’ energy storage in vehicles and other technology.

The batteries in today’s electric cars constitute a large part of the vehicles’ weight, without fulfilling any load-bearing function.

A structural battery, on the other hand, is one that works as both a power source and as part of the structure—for example, in a car body.

The Australian Snowy 2 hydro scheme plans to use electricity to pump water up hill to get some of that energy back by running the water downhill again, writes Viv Forbes @ The Saltbush Club.

Some Australian mining companies are planning a dry version of Snowy 2 – a huge brick-powered battery using the force of gravity to drive a generator when solar and wind energy are on strike.

Each unit of this brick-powered battery would comprise a 30 storey tower enclosing a 35 tonne brick which is hauled up using surplus renewable energy (around noon on any clear windy day) and then released to turn generators when there is no renewable energy being produced (every still night or calm cloudy day).

These flint-stone miners will also have to replace all diesel mining equipment with electric machines, then build enough wind/solar generators to not only run the mine, but also to elevate the giant bricks.

The idea would be to have either a smaller site or a lower site, compared to a standard pumped hydro scheme, or a combination of both. Reasonable cost is suggested.

An energy storage system from RheEnergise could be installed on thousands of hills around the UK, according to the company.

It uses dense liquid, which is two-and-a-half-times denser than water, and could therefore potentially provide two-and-a-half-times the power of equivalent conventional systems, reports Elemental.

As reported by Professional Engineering, the High-Density Hydro systems would be built underground.

Another ‘net zero’ stumbling block for climate-obsessed governments is investigated by researchers. This time it’s the question of where and how to keep all the hydrogen – assuming it can be produced from renewables on an industrial scale in the first place.

Large-scale storage of hydrogen remains largely untested but is essential if hydrogen is to realize its potential to make a significant contribution to achieving net-zero emissions, says TechXplore.

A new perspectives paper sets out the key scientific challenges and knowledge gaps in large scale hydrogen storage in porous geological environments.

These underground hydrogen reservoirs could be used as energy storages to face high demand periods.

Solar power complex in California [USA. Gov – BLM – Bureau of Land Management]


Welcome to the inglorious green revolution, where the lives of ageing gas power plants have to be extended and various other mini ‘solutions’, some relying on equipment owned by individual citizens, have to be adopted in a frantic effort to keep the lights on. Of course none of this was necessary before renewables were deemed to be the future of electricity supply, in the vain hope of altering the climate. What’s next if these measures are not enough?
– – –
Sometime next summer, there’s a decent chance a heat wave will bake the American West, and California’s power grid will again be stretched to its limits, says TechXplore.

As the sun sets, solar panels will start generating less electricity even as temperatures remain high.

Power plants that burn natural gas will fire up as quickly as possible, in a race to keep air conditioners blowing and avert the need for rolling blackouts.

But the fossil fuel won’t be alone in riding to the rescue.

As power supplies tighten, lithium-ion batteries—some connected to sprawling solar farms in the desert and others tucked away in household garages—will dispense electricity produced during the afternoon sunlight.

A small but growing number of household batteries will be part of coordinated networks, discharging in unison as dictated by the needs of the grid.

Meanwhile, millions of people will cut back on electricity use in their homes, in some cases because state officials asked nicely and in others because they’re getting paid to conserve.

All these battery systems can do is give power providers a brief window to figure out what they’re really going to do about the imminent blackout situation, due to the latest weather-related dip in renewable power generation.

PA Pundits - International

By David Wojick, Ph.D. ~

New York City will soon be home to the world’s biggest utility-scale battery system, designed to back up its growing reliance on intermittent renewables. At 400 MWh this batch of batteries will be more than triple the 129 MWh world leader in Australia.

The City of New Yorks director of sustainability (I am not making this title up), Mark Chambers, is ecstatic, bragging: Expanding battery storage is a critical part of how we advance momentum to confront the climate emergency while meeting the energy needs of all New Yorkers. Today’s announcement demonstrates how we can deliver this need at significant scale.” (Emphasis added)

In reality the scale here is incredibly insignificant.

In the same nonsensical way, Tim Cawley, the president of Con Edison, New York’s power utility, gushes thus: Utility scale battery storage will play a vital role in…

Come the next potential blackout situation, the battery could give Victorians up to an hour to find a way out of trouble. But making the wind blow harder or the sun shine more won’t be among their options, of course.

Australia is poised to construct one of the world’s largest batteries, using Tesla’s technology for lithium-ion batteries, reports TechXplore.

The football-field sized battery will provide up to 300 megawatts of power output and 450 megawatts-hours of storage in a country that has been struggling to meet energy demands during skyrocketing power usage triggered by record-breaking temperatures.

Last year, Australia suffered its hottest and driest year ever, with temperatures topping 121 degrees Fahrenheit last December.

The battery, known as the Victorian Big Battery Megapack, will be located in the state of Victoria, Australia’s second most populous region.

Liquid air energy storage: Highview’s 5 MW pre-commercial demonstrator [credit: ModernPowerSystems]


Under the heading ‘Cool air technology for a cooler planet’, the firm behind the scheme says:
‘Our CRYOBattery can deliver anywhere from 20 MW/80 MWh to more than 200 MW/1.2 GWh of energy and can power up to 200,000 homes for a whole day. We do this at half the cost of lithium-ion batteries and release zero emissions in the process.’
The system is intended to run on surplus night-time output from wind farms, but as ever, converting electricity to some form of storage and then back to electricity again is adding yet more costs and complexity to the system.

– – –
Work is beginning on what is thought to be the world’s first major plant to store energy in the form of liquid air, reports BBC News.

It will use surplus electricity from wind farms at night to compress air so hard that it becomes a liquid at -196 Celsius.

Then when there is a peak in demand in a day or a month, the liquid air will be warmed so it expands.

The resulting rush of air will drive a turbine to make electricity, which can be sold back to the grid.
