[font size=4]KTH researchers have opened a route to large-scale hydrogen production by discovering a better way to split water without relying on precious metals.[/font]
[font size=3]If a cheap, stable and efficient way could be found to produce hydrogen from water, a hydrogen-fuel economy could finally become a reality.
…
Last week his team reported in Nature Communications that it has discovered that a new material composed of common earth-abundant elements could be used as a catalyst for water splitting, which could help change the economics of large scale hydrogen fuel production.
Researcher Ke Fan says that the new material is a monolayered double hydroxide involving nickel and vanadium, which offers a state-of-art electrocatalyst for water oxidation. The low-cost, highly efficient nickel-vanadium monolayer outperforms other electrocatalysts that are composed of non-precious materials, Fan says. And it offers a competitive, cheap alternative to catalysts that rely on more expensive, precious materials, such as iridium oxide (IrO2) or ruthenium oxide (RuO2).
"This is the first time that the metal, vanadium, has been used to dope nickel hydroxide to form a water oxidation catalyst, and it works very well — even beyond our expectations," Fan says. "No doubt this material can greatly expand the scope of non-precious metal elements of electrocatalysts, and it opens new areas for water splitting."

That's in the UK. Denmark has around 11 hydrogen stations across the country, you can drive throughout the nation on H2 produced from renewable energy. Ask around- you'll find that hardly anyone in the US knows about it. Now why is THAT?
H2 LOGIC DELIVERS NINTH HYDROGEN FUELLING STATION FOR DENMARK
MARCH 3, 2016: Today a new hydrogen fuelling station, delivered by H2 Logic, was inaugurated in Kolding. This narrows the driving distance to the nearest station in Hamburg, Germany to only 245km (150 miles) making cross-border driving on hydrogen even more comfortable. The station in Kolding is the third to open in Denmark during the past six months, and in total the ninth public accessible hydrogen station in 24/7 operation throughout Denmark – underlining the status as the world’s first countrywide hydrogen station network.
The entire Danish hydrogen station network is based entirely on hydrogen produced from electrolysis and electricity procured with CO2 certificates. This ensures a 100% sustainable and zero emission hydrogen supply – the highest share in the world for an entire station network....

...in rather large quantities.
If they run a few electrolyzers with wind power that they can't dump because it's being produced when nobody needs it, it remains insignificant. The entire output of all the wind crap that Denmark's strewn around its country side and in the North Sea near it's oil and gas fields doesn't equal the output of two large coal plants.
Hydrogen is a thermodynamic - and in this case a marketing - shell game that wastes energy on a planet whose atmosphere is collapsing at the fastest rate ever observed. When one makes hydrogen using electricity, one is wasting electricity in a highly inefficient process. This basic scientific truth is, or should be, taught in every high school chemistry class.
We've heard endlessly about the assholes in Denmark and their idiotic wind program, but the fact is that they have no intention of stopping offshore drilling in the North Sea for oil and gas,.
Like all oil and gas producing bullshit artists in Scandinavia they are playing a very stupid bait and switch game, crowing loudly about their useless so called "renewable energy" schemes while working continuously to get as much money as they can from participating in the destruction of the planetary atmosphere.
Seen in this way, cheap marketing pictures of hydrogen filling stations are purely obscene.
Because many people are scientifically illiterate, and don't know a damned thing about the second law of thermodynamics, or for that matter fundamental gas laws, they pass this garbage around as if it were meaningful.
It is not. It is a grotesque failure on a vast scale. The weekly averages for increases in carbon dioxide in the atmosphere in 2016 is running at 3.80 ppm over 2015. This is an unprecedented rate of degradation of the atmosphere never seen before in human history.
Who gives a shit about a couple of for show hydrogen stations in an oil and gas drilling hellhole nation jutting into the North Sea?
They lack both the guts and the integrity to shut these things off (if we must have a picture of the real Danish interest:
Oil and Gas People: Denmark Awards Offshore Blocks to 12 Oil Firms
If one opened science books, rather than hawking ridiculous Arnie Schwarzenegger hydrogen car CULTure fantasies, which have been pipe dreams for nearly half a century now, one would give a shit about realistic solutions. But that's not the case. We'd rather lie to ourselves, and so destroy the future for all following generations.
Enjoy the coming holiday.
