In Australia, the University of Sydney reported that researchers have created a process using liquid metals, powered by sunlight, that can produce clean hydrogen from both freshwater and seawater.
The method allows researchers to ‘harvest’ hydrogen molecules from water while also avoiding many of the limits in current hydrogen production methods, according to the university.
“We now have a way of extracting sustainable hydrogen, using seawater, which is easily accessible while relying solely on light for green hydrogen production,” said lead author and PhD candidate Luis Campos.
At the technology’s heart is gallium, a metal with a low melting point, meaning it needs less energy to transition from a solid into a liquid.
