Australia has figured out how to extract moisture from desert air to produce energy

To export energy over a distance, you need a lot of water. However, in the case of arid and

desert areas - they simply have such luxurynot. A new project in the Australian outback will test an innovative technology for converting solar energy into hydrogen by trapping moisture from the air and separating it through hydrolysis, which will allow hot arid regions to become energy exporters.

The pilot city will be Tennant Creek, located on the northern edge of Australia's famous red center, a colossal expanse of rocky desert.

As in most of the northern territoryAustralia, there is a lot of sun, but not a ton of water to export energy. As Australia strives to become a hydrogen-based green energy exporter, Tennant Creek is a good place to try out a new technology that does not require large volumes of municipal water or a local electricity connection.

New startup Aqua Aerem signed withthe North Carolina state government is contracted to conduct 12 weeks of testing of the solar + air + hydrogen system. The energy will be captured through a dual-axis tracking photovoltaic concentrator system, which the company says will capture energy twice as efficiently as a conventional silicon panel.

The next step is to transform this energyinto transportable hydrogen through electrolysis, which requires only electricity and water as inputs. Here Aqua Aerem applies its secret sauce: an atmospheric water capture system that sucks moisture out of the air. According to the company, it works more efficiently in warmer climates, requires little maintenance and produces no waste other than air. Tests will mainly focus on the process of capturing water, the rest of the elements are currently quite mature technologies.

“This test is the first phase of a pilota renewable hydrogen project, the North Carolina government said in a statement, that will ultimately produce renewable hydrogen for the Tennant Creek power plant.

Future proposed Aqua Aerem systemincludes the installation of a 15-megawatt electrolyser, which the company estimates will produce about 912 tons of green hydrogen per year, providing about half of the energy used by Tennant Creek.
