Not exact matches

Kanzius had essentially replicated the centuries - old method of water electrolysis, separating water into hydrogen and oxygen gases by running a current through water loaded with salt, which makes it conductive.
In an article published Jan 26 in Nature Chemistry, nanotechnology experts from Stanford Engineering and from Denmark's Aarhus University explain how to liberate hydrogen from water on an industrial scale by using electrolysis.
Therefore, it must be first generated (e.g., by electrolysis of water), then stored, to be finally used — ideally in fuel cells transforming chemical energy directly into electrical one.
«Hydrogen (H2) produced from water splitting by an electrochemical process, called water electrolysis, has been considered to be a clean and sustainable energy resource to replace fossil fuels and meet the rising global energy demand, since water is both the sole starting material and byproduct when clean energy is produced by converting H2 back to water,» the researchers wrote.
Stone's proposed venture would create rocket fuel by melting water ice from the moon's soil, purifying it (exactly how, he says, is a trade secret), and splitting it into hydrogen and oxygen, perhaps using a solar - powered electrolysis system.
«Hydrogen production by electrolysis of water is the greenest way to convert electricity to chemical fuel,» said Junhua Song, a WSU Ph.D. student who synthesized the catalyst and performed most of the experimental work.
1) Alkaline water electrolysis: In alkaline electrolysis the membrane prevents the hydrogen and oxygen products from mixing, however commonly available membrane separators often become brittle and crack with low pH. The membranes developed at SNL are stable under basic environments and have been tested by LANL and ProtonOnsite.
The water is made by an electrolysis unit (see patent here), which has a port into which either salt (NaCl) or calcium glycerophosphate can be added.
The color of the water is caused by a reaction of the salt water and the electrolysis array, which creates rust.
The water of the swimming pool water is purified by environmentally - friendly salt electrolysis, according to international standards.
Operators can convert electrical energy into stored chemical energy in hydrogen by using electricity for electrolysis, which splits water into oxygen and hydrogen.
Producing hydrogen and oxygen by the electrolysis of water (the hydrogen could later be used to power clean fuel - cell vehicles, oxygen has many uses);
Hydrogen, which is the simplest form of energy carrier, can be generated renewably with solar energy through photoelectrochemical water splitting or by photovoltaic (PV)-- driven electrolysis.
And with US electricity generation dominated by coal, H2 from electrolysis — cracking water into its components using electricity — looked more like a way to shift, rather than reduce vehicle emissions.
Researchers at Stanford University have demonstrated solar water splitting by photovoltaic - electrolysis with a solar - to - hydrogen (STH) efficiency of more than 30 % — a new record.
That said, there are seductive small - scale options emerging, like the Fronius Energy Cell system in which any excess electricity from a PV cell used to decompose water into oxygen and hydrogen by electrolysis.
NaOH is made by electrolysis of salt water.
Hydrogen can also be generated by electrolysis of water by using extra electricity generated by wind and / or solar collection to be stored for burning in power plants when those collection systems have lulls especially for solar at night, of course.
The extra hydrogen is harder to come by, electrolysis of water is probably the most feasible option.
[7] Oxygen is produced industrially by fractional distillation of liquefied air, use of zeolites with pressure - cycling to concentrate oxygen from air, electrolysis of water and other means.
The production of chlorine by solar - powered electrolysis prevents the re-growth of undesirable bacteria in the recycled water.
There is still some pretty high tech stuff going on here to recirculate that water; it is put through a bioreactor, a membrane, using new tech developed by Eawag, treated by electrolysis and then chlorinated.
Carbon Commentary; 2017/07/05, Chris Goodall; «Hydrogen made by the electrolysis of water is now cost - competitive and gives us another building block for the low - carbon economy».
Electrolysis, which uses electricity to break hydrogen away from oxygen in water can be powered sustainably by renewable energy.
