How the world’s first sand battery stores green power – BBC News
The world’s first fully working “sand battery”, which can store green power for months at a time, has been installed by Finnish researchers.
The developers said 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 US said it has hit “dozens” of Iranian military targets in overnight attacks, in response to Iran hitting commercial ships in the Strait of Hormuz.
The military said it struck “air-defense systems, coastal radar sites, missile and drone capabilities, and small boats”, using aircraft, ships, and drones – including “one-way attack sea drones for the first time”.
“The Strait of Hormuz is a vital maritime corridor for global trade,” the US military said. “Iran does not control it”.
In response, Iran said it targeted US bases in Jordan, Bahrain, and Kuwait and also radar systems in Oman.

President Donald Trump has said the US is reinstating a naval blockade of Iranian ports and will impose a 20% charge on all cargo shipped through the Strait of Hormuz following days of escalating strikes between the two countries.
He said this would stop “Iran’s ships or customers” from entering or leaving the key oil shipping route, but “all other countries will have fair and open use of the Strait”.
Iran’s foreign minister later said whoever provides safe passage “should be compensated for this service”, but Iran would remain the strait’s “GUARDIAN” – using Trump’s word.
Tehran and Washington clashed over the strait’s control after exchanging strikes in the region overnight and on Monday.
The US said it carried out strikes against military targets in Iran, targeting air defence systems, coastal radars, and missile and drone sites. Iran said it responded by striking US military bases in Kuwait, Jordan and Bahrain, and radars in Oman.

Wildfires of ‘exceptional scale’ have taken force in Paris, as neighbouring Spain still tackles flames across the country following its own devastating fires.
Now the UK is also experiencing wildfires in England and Wales, as its third heatwave of the year is set to intensify again this week.
Here’s what we know so far about the extent of wildfires in Europe and the UK, and how heatwaves are impacting them.

Explosions have been heard near two Iranian port cities, Bandar Abbas and Bushehr, state media has reported.
It comes after another night of strikes between the US and Iran, with Iran’s Islamic Revolutionary Guard Corps saying it hit two UAE tankers in the Strait of Hormuz and targeted US facilities in Jordan and Bahrain.
The UAE called the attack “brazen”, adding that an Indian crew member was killed and eight others were injured.
Meanwhile, the US military says it completed strikes on targets aimed at degrading “Iran’s ability to attack commercial shipping” – Iranian state media reports three people were killed.

The US military said it was carrying out a new wave of strikes on targets in Iran. It said the aim of the attacks was to degrade Iran’s ability to attack shipping in the strait of Hormuz. It came ass the US Navy resumed its blockade of Iran’s ports.
Iran said that control of the strait of Hormuz was required for its national security and it will exercise sovereignty over the key shipping lane, whatever the cost.
President Trump announced that he was scrapping a plan he had announced a day earlier, for placing a 20% toll or tariff on all cargos passing through the strait of Hormuz.

Ahem…electricity is an ‘energy vector’ – a means of energetic transmission – not a fuel – you use the sand-stored heat to create electrical impulse if you wish…be funny if you could store it – like a nest of elvers!

If there is anything good about Russias continuing aggression, it has jump started an continental shift in European motivation to rid them off our back. Europe will lead transfer to clean energy in coming years. Free of pollution, and free of russians.

You can convert heat to electricity, but the efficiency depends on the temperature. At 1700C, the melting point , you can get a theoretical maximum efficiency of about 85%. Also for heat loss the loss is proportional to the surface area, where the energy stored is proportional to volume. Surface area increases in proportion to the square of the dimension, where volume is the cube, hence the larger it is the longer the energy will be stored. I give it the thumbs up. It would be way cheaper than batteries.

what they are talking about? 1kg of water needs ~4100j per 1C but sand needs only 800j its 5 times less so if you hear the sand to 500c then you store nearly the same as water in 100c. Also water under pressure can go higher like 120C

Best idea for concentrated solar power, and CSP sounds better than solar panels to me (for an energy farm). But for wind and hydro energy I'd go for gravity batteries.

Finally, sensible,economically viable energy storage that is non polluting and doesnt use scarce resources like nickel,cobalt and lithium. Being able to store heat at up to 600C is incredibly useful for making hot water, or to run stirling engines for power generation. The higher the energy difference against ambient, the higher the efficiency.

Is great so long as humans don't start wrecking sand eco systems much like the aggregates industry trashes the sea floor and ruins fishing areas in order to keep pouring concrete . Wholistic approach will always be our best and safest bet. To sum up, the planet is out of balance due to lack of consideration for all other species and plant life, restoring balance is the true goal for 21 century and beyond.

เป็นความคิดสร้างสรรค์ที่ดี แต่ไม่น่าสนใจเพราะระบบมีความยุ่งยากซับซ้อนกับการเปลี่ยนรูปแบบพลังงานหลายขั้นตอนทำให้ต้องลงทุนสูง
การเปลี่ยนรูปแบบพลังงานหลายขั้นตอนมีความสูญเสียพลังงานในขั้นตอนการเปลี่ยนรูปของพลังงาน
และที่สำคัญในช่วงที่เกิดวิกฤติจากความหนาวระบบนี้อาจจะไม่สามารถช่วยชีวิตคนได้ แต่ถ้าต้องการจัดเก็บพลังงานสำรองไว้ให้เพียงพอก็จะต้องมีระบบที่ใหญ่ขึ้น นั่นคือต้นทุนสูงขึ้น ค่าพลังงานก็จะต้องมีราคาที่สูงขึ้น
และที่สำคัญในระดับครัวเรือนไม่สามารถสร้างระบบนี้ขึ้นมาใช้เองได้ ระบบนี้เหมาะกับการผลิตเพื่อแจกจ่าย
สรุปแล้วระบบนี้มีประโยชน์ต่อโลกของเราเป็นพลังงานสะอาดที่ไม่ทำให้เกิดภาระโลกร้อนเพิ่มขึ้น แต่ไม่ได้ช่วยลดภาระโลกร้อน และประโยชน์กับประชาชนชนไม่ได้ดีกว่าระบบการผลิตแบบอื่น
