A study led by UCLA researchers could help accelerate the use of hydrogen as an environmentally friendly source of energy in transportation and other applications.

The team developed a method for predicting platinum alloys’ potency and stability—two key indicators of how they will perform as catalysts in hydrogen fuel cells. Then, using that technique, they designed and produced an alloy that yielded excellent results under conditions approximating real-world use. The findings are published in the journal Nature Catalysis.

“For the sustainability of our planet, we can’t keep living the way we do, and reinventing energy is one major way to change our path,” said corresponding author Yu Huang, a professor of materials science and engineering at the UCLA Samueli School of Engineering and a member of the California NanoSystems Institute at UCLA. “We have fuel cell cars, but we need to make them cheaper. In this study, we came up with an approach to allow researchers to identify the right catalysts much faster.”

Circa 2018 unlimited energy using graphene.

University of Arkansas researchers have shown that the motion of graphene could supply an unlimited amount of clean energy. (Image credit: Pixabay)Graphene advancements are rolling out on a regular basis, with new developments in production 0, strength 0, and have even used it to create 3D printed objects. Researchers from the University of Arkansas have also utilized the material to create a source of potential unlimited clean energy, thanks to its flexibility.

Each potential flight will last more than a month.

With that out of the way, Artemis I should be able to fly in late August or early September.

Stir this silicon-based powder into water, and hydrogen will bubble out, ready for immediate use. Hong Kong company EPRO Advance Technology (EAT) says its Si+ powder offers an instant end to the difficulties of shipping and storing green energy.

This is the second powdered hydrogen advance we’ve learned about this week, designed to solve the same problems: transporting hydrogen is difficult, dangerous and expensive, whether the costs are for cryogenic cooling in a liquid hydrogen system, or for compression to around 700 times the normal sea-level air pressure.

New electrocatalysis electrodes have been created that are simpler and cheaper than conventional ones, and can substantially increase the efficiency of water splitting. Decorated with chiral molecules like helicenes, these devices double the activity of the oxygen evolution reaction, the bottleneck of the process, and improve its selectivity.

‘With electrocatalysis, we [can] use electrons from renewable sources [like solar and wind] to produce clean chemicals and fuels,’ explains Magalí Lingenfelder from the Max Planck–EPFL laboratory for molecular nanoscience and technology, in Switzerland, who led the study. In this work, her team focused on the oxygen evolution reaction. ‘It’s the bottleneck of water splitting,’ she says. ‘We wanted to increase its performance with cheap, simple solutions.’

To get around this problem, Kanté and colleagues utilized photonic crystals. These are periodic structures, which, like electronic semiconductors, have “band gaps” – frequencies at which they are opaque. Like graphene in electronics, photonic crystals generally contain Dirac cones in their band structures. At the vertex of such a cone is the Dirac point, where the band gap closes.
