Another hydrogen transport powder emerges, promising double the density

Posted by in categories: chemistry, energy

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.

Chiral molecules beat magnets when it comes to boosting water splitting

Posted by in categories: chemistry, energy, nanotechnology

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.’

New semiconductor laser delivers high power at a single frequency

Physics World


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.

Mechanochemical breakthrough unlocks cheap, safe, powdered hydrogen

Posted by in categories: chemistry, energy, nanotechnology

Australian scientists say they’ve made a “eureka moment” breakthrough in gas separation and storage that could radically reduce energy use in the petrochemical industry, while making hydrogen much easier and safer to store and transport in a powder.

Nanotechnology researchers, based at Deakin University’s Institute for Frontier Materials, claim to have found a super-efficient way to mechanochemically trap and hold gases in powders, with potentially enormous and wide-ranging industrial implications.

Mechanochemistry is a relatively recently coined term, referring to chemical reactions that are triggered by mechanical forces as opposed to heat, light, or electric potential differences. In this case, the mechanical force is supplied by ball milling – a low-energy grinding process in which a cylinder containing steel balls is rotated such that the balls roll up the side, then drop back down again, crushing and rolling over the material inside.

Goodbye, Oil: US Navy Cracks New Renewable Energy Technology To Turn Seawater Into Fuel, Allowing Ships To Stay At Sea Longer

Posted by in categories: energy, military, sustainability

Circa 2014


After decades of experiments, U.S. Navy scientists believe they may have solved one of the world’s great challenges: how to turn seawater into fuel.

The development of a liquid hydrocarbon fuel could one day relieve the military’s dependence on oil-based fuels and is being heralded as a “game changer” because it could allow military ships to develop their own fuel and stay operational 100 percent of the time, rather than having to refuel at sea.
