Rust brings boost to solar energy potential

Feb. 8 Using the power of sunlight, Swiss scientists are developing methods of extracting inexpensive, safely transportable, hydrogen fuel from iron oxide commonly known as rust. The process essentially converts solar power into hydrogen, vastly canada goose store increasing the potential Canada Goose Online of solar energy to serve as a viable renewable energy source across the world. Jim Drury met the scientists behind the research.

But hydrogen’s potential as Canada Goose Outlet a clean, renewable source of energy is also extremely attractive and laboratories around Canada Goose Jackets the world, are looking for ways to store and canada goose coats on sale exploit it safely.

Scientists at the EPFL institute in Lausanne, believe https://www.officialcanadagoosesoutlet.ca they’ve found one.

These are microscopic hydrogen bubbles being produced by an unexpected source iron oxide, commonly known as rust.

The researchers believe molecular hydrogen extraction using iron oxide, buy canada goose jacket cheap sunlight, and water presents an inexpensive eco friendly solution for uk canada goose storing renewable energy.

Ludmilla Steier is one of cheap canada goose uk the EPFL team.

SOUNDBITE (English) LUDMILLA STEIER (PRON: STY ER), PHD STUDENT, SAYING:

“Right now it’s just actually the canada goose clearance sale air canada goose uk black friday taking the solution of iron canada goose factory sale acetylacetonate and so combined with the heat it’s transformed into iron oxide.”

The iron oxide is more highly developed than that found on a rusting car. It’s nanostructured, enhanced with silicon oxide, and covered with a nanometer canada goose clearance thin layer of aluminium canadian goose jacket oxide and cobalt oxide.

A layer of dye and titanium dioxide lets electrons transferred by the oxide gain sufficient energy to extract molecular hydrogen.

The team is working on a variety of methods of extraction.

SOUNDBITE (English) KEVIN SIVULA, ASSISTANT Canada Goose sale PROFESSOR OF canada goose CHEMICAL ENGINEERING AT EPFL, SAYING:

“We can canada goose uk outlet take nanoparticles of iron oxide and disperse them in a liquid, making something like a paint which we can just paint onto our substrates, leaving a nanostructured iron oxide behind. In another more efficient way Canada Goose online we can deposit iron oxide by essentially smoking it onto the substrate by making very small particles Canada Goose Coats On Sale of iron oxide particles in a gas phase and having them hit the substrate we can make high surface area iron oxide, which is precisely doped with the right amount of silicon that we need to have a high performance electrode.”

Producing the chemical is done buy canada goose jacket by uk canada goose outlet splitting water into its atomistic components oxygen and hydrogen.

The team says it’s a technique that can be used anywhere in the canada goose black friday sale world, solving one of the biggest problems caused by transporting hydrogen its inherent volatility.

PhD student Maurin Cornuz believes the painting method could yield the best results.

“We moved into the ink process that allows us much better control for the morphology, the nanostructuring of canada goose coats the electrodes and also can be translated to a roll to roll process, so a large scale deposition.”

The team believe the system could vastly increase the potential of storing solar energy world wide.

SOUNDBITE (English) KEVIN SIVULA, ASSISTANT PROFESSOR OF CHEMICAL ENGINEERING Canada Goose Outlet AT canada goose uk shop EPFL, SAYING:

“Iron Canada Goose Parka oxide is potentially extremely inexpensive, so it could compete even at a lower level of efficiency. That said, our efficiency being only at one to two percent does need to get up a little bit higher before these devices could be commercial. So to do that we’re really digging deep into the science both of the nanostructure of the iron oxide, but also the electrochemical processes that are occurring in the material in order to first determine what the loss processes are and then to make them better.”

The team is excited about the potential of their research. Learn more about Thomson Reuters products:.
