Researchers from the USA have developed a method to produce "green" hydrogen from aluminium, which is used for example in cola cans, and salt water.
As a fuel, hydrogen can turn the entire transport sector upside down. At least when it comes to CO2 emissions.
Now some American researchers have succeeded in extracting hydrogen from the aluminum in used cola cans and salt water from the sea.
The researchers from the Massachusetts Institute of Technology (MIT) have found that the aluminum reacts with salt water and, among other things, can produce hydrogen gas and heat.
The Americans' research indicates that the rare metals such as gallium and indium, which would otherwise be used to produce 'green hydrogen', can be recycled more easily.

The 'simple' discharge is seawater. Furthermore, caffeine, which is found in e.g. coffee grounds, also effective. The researchers found this all out by pure chance.
– When we added coffee grounds to the salt water and then threw in the pre-treated aluminum pellets, the reaction suddenly happened much faster than in pure seawater, says the lead researcher behind the project Aly Kombargi, according to the media.
Kombargi is sure that the research team's discovery can be used to produce hydrogen as a fuel in a greener and more efficient way than is the case today.
And that is good news for both motorists and car manufacturers. A number of car brands – including Toyota and BMW – are also adamant that the idea of hydrogen as a fuel should not just be thrown away.
Both brands are also experimenting with rebuilt internal combustion engines that use hydrogen instead of petrol. The residual product? Water.
Something completely different is the production of synthetic petrol and diesel. It divides the waters. Because while the German car brands in particular call it a waste to ban the development as part of the EU's ban on new internal combustion engines in 2035, others call it nonsense.
Drivers just have to adjust and accept that there is no alternative to the electric car. This is how it sounds, among other things from an analysis company. Read more about it here .
