Researchers split seawater without pre-treatment to produce green hydrogen

Green Car Congress

Researchers from the University of Adelaide and Tianjin University have successfully split seawater without pre-treatment to produce green hydrogen. The use of vast amounts of high-purity water for hydrogen production may aggravate the shortage of freshwater resources. A paper on the work is published in Nature Energy.

Eni and RenOils to boost collection of used cooking oil for biofuel production

Green Car Congress

As well as clogging domestic drains and the network as a whole, increasing maintenance costs, disposal through the sewage network impairs the correct operation of the purification systems and increases those costs too. If it ends up in water, it forms a film that prevents the passage of sunlight, causing huge damage to the environment.
