RE: 20 cubic metres of water per ton of hydrogen25 Oct 2025 21:27
However to put this into perspective, producing just 1 kilogram of cotton requires around 10,000 liters of water and a cotton t-shirt requires around 2,700 liters of water to produce. (this what happens when you can't go to the pub on a Saturday night, wonder how many litres of water it takes to brew a pint of beer)
