Seawater split to produce 'green' hydrogen Date: February 1, 2023 Source: University of Adelaide Summary: Researchers have successfully split seawater without pre-treatment to produce green hydrogen.

Seawater electrolysis can be a carbon-negative method for producing minerals such as calcium carbonate (shown) for cement and other building materials. Northwestern University.

In conventional electrolysis, chloride ions in seawater penetrate the electrode and interact with the catalyst, creating hypochlorite ions, an unwanted byproduct that poisons the catalyst, Cerruti ...

University of Tsukuba researchers develop highly durable electrodes for hydrogen production from seawater. The multi-elemental alloy electrode can sustain anode performance for over a decade ...

Barriers to development of seawater electrolysis technologies Date: February 19, 2020 Source: University of Liverpool Summary: Researchers have identified the key technological and scientific ...

Producing hydrogen via seawater electrolysis has the nasty habit of also producing toxic chlorine gas, so current hydrogen production relies on pure water—a resource that’s becoming more and ...

“We have split natural seawater into oxygen and hydrogen with nearly 100 per cent efficiency, to produce green hydrogen by electrolysis, using a non-precious and cheap catalyst in a commercial ...
