Collaboration of scientists transform thin air into green hydrogen. There are cleaner, renewable energy sources available, though solar and wind installations have a challenge in that energy needs to be stored in large batteries for later use. This might not fit with the idea of sustainable living.
We have also noticed the negative side of lithium mining. There are large stretches of land covered in salt flats that endanger local flora, fauna, and communities. These problems come from pumping brine with high levels of lithium to extract more lithium.
The future solution to the problem is sustainable energy, such as hydrogen power.
Green as it can Get
Hydrogen is one of the most efficient types of fuel we have, because it creates only water. And because hydrogen can be created from things like solar rays, it’s also a clean type of energy.
The use of water electrolyzer machines is generating clean energy for projects. Scientists hope that this technology will help make the world healthier and more sustainable by being less dependent on fossil fuels.
There is a strong mismatch between the availability of renewable and non-renewable resources. Water is scarce to meet local needs in regions with wind and solar, while renewables are scarce in areas with enough fresh water for hydrogen fuel.How to collect water from the air?
An international research project composed of scientists from China, Australia, and the U.K. wants to use the moisture in the air to create hydrogen, which they assert could be used to solve water drought.
The team of scientists used a hygroscopic electrolyte to generate electricity from the sun or wind. In their experiment, they managed a Faradaic efficiency of 95%.
The team tested their prototype in dry areas with four percent relative humidity and found that it was sufficient. The technology can be scaled, which means it could be used to provide hydrogen fuel sustainably to dry, semi-dry and remote regions of the world.

The most promising energy carrier of the low-carbon economy is green hydrogen, produced through water splitting. However, due to the geographic mismatch between renewables distribution and freshwater availability, this poses a significant challenge. In addition, such a system would be reliant on a continuous water supply – with potential fluctuations in production.
This can be circumvented by directly producing hydrogen from the air using artificial hygroscopic electrolytes and electrolysis powered by solar or wind power. This system can maintain consistent production with efficiency at around 95%, and can be adapted for remote areas that have no water supply but still need energy production.
