New stable water-splitting catalyst doesn’t require expensive iridium

Green Car Congress

Researchers have developed a nickel-stabilized, ruthenium dioxide (Ni-RuO 2 ) anode catalyst for proton exchange membrane (PEM) water electrolysis. The Ni-RuO 2 catalyst shows high activity and durability in acidic OER for PEM water electrolysis. 2 , suggesting potential for practical applications. —Wu et al.

Stanford researchers develop new electrolysis system to split seawater into hydrogen and oxygen

Green Car Congress

A Stanford-led team has developed a new electrolysis system to split seawater in hydrogen and oxygen. Hongjie Dai and his research lab at Stanford University have developed a prototype that can generate hydrogen fuel from seawater. Electrolysis of water to generate hydrogen fuel is an attractive renewable energy storage technology.

US DOE releases 2023 Critical Materials Assessment to evaluate supply chain security for clean energy technologies

Green Car Congress

While cobalt (Co) was found to be critical in this and previous reports, lithium (Li) becomes critical in the medium term due to its broader use in various battery chemistries and the rampant growth of the EV industry. Natural graphite is a new addition in this assessment and is also found to be critical.

Researchers develop non-flammable fluorinated electrolyte for Li-metal anodes with aggressive cathode chemistries; toward a 500 Wh/kg goal

Green Car Congress

Researchers at the University of Maryland (UMD), the US Army Research Laboratory (ARL), and Argonne National Laboratory (ANL) have developed a non-flammable fluorinated electrolyte that supports the most aggressive and high-voltage cathodes in a Li-metal battery. Li metal offers one of the highest specific capacities (3,860 mAh g ?1

GWU team demonstrates relatively efficient electrochemical process for low-GHG production of ammonia

Green Car Congress

A team at George Washington University led by Stuart Licht has developed a relatively efficient electrochemical process for the production of ammonia from water and nitrogen, without the need for an independent hydrogenation step (and thus the associated carbon-intensive steam reforming of methane as the hydrogen source). 1254234.
