Can '#WaterBatteries' help farmers tackle #drought?

Kirk England, 21 October 2025

"#Rainwater used to surge through Will Luke's dairy farm whenever there was a downpour.

"He used to watch it flow away but concerns over 'drier and drier' summers led him to build a storage pond allowing him to put that water to use - particularly for livestock.

" 'Once it leaves the farm, it's no good to me. If we capture the water we can get more use out of it. We're much more resilient,' said Mr Luke, whose farm is near Plymouth, Devon.

"The Westcountry Rivers Trust said #ponds and #wetlands were insurance for 'times of need' including droughts, and it was now leading a €8m (£6.95m) project on how the so-called 'water batteries' could be used to create a 'smart water grid' across Europe."

#FUD.... clear and simple. This is a storage problem, not a generation problem. We need #WaterBatteries, chemical, and #heatbatteries, to store this peak generation for offpeak usage!

#Germany has too many #solarpanels, and it's pushed energy prices into negative territory
On average, the price received was 9.1 euros per megawatt-hour, significantly under the 70.6 euros paid during non-solar-power hours.

Germany has too many solar panels, and it's pushed energy prices negative

Germany has installed a record number of solar panels. But consumers aren't starting to use them fast enough.

Greener ‘#waterbatteries’ a step closer thanks to breakthrough by Melbourne researchers: they are Cheaper, Recyclable, And Won't Explode
'#Water #batteries' known as aqueous metal-ion batteries. They use metals such as magnesium or zinc, which are cheaper to assemble and less toxic than the materials currently used in other kinds of batteries. In a #waterbattery, electrolytic fluid is water with a few added salts, instead of something like sulfuric acid or lithium salt.
