[RE-wrenches] NFS3 (or is it nsf?)

[Christopher Freitas]

They are talking about THIAZYL FLUORIDES, NSF &NSF3 and Derivatives of
such as SF5NH2' SF5NSF2' SF5NSO, SF5NSCL2, (SF5N)2SF2' SF5NCL2, SF5NHCL.
They are used in all kinds of cleaning substances used industrially and
in our homes.  

 

As far as its use in solar panel production - they are common in
thin-film type panels - not silicon crystal type panels.  

 

Here is the article I think you heard - 

Greenhouse Gas Comes from Solar Panels

Think switching to solar energy will make you green? Think again. Many
of the newest solar panels are manufactured with a gas that is 17,000
times more potent than carbon dioxide in contributing to global warming.

Nitrogen trifluoride, or NF3, is used for cleaning microcircuits during
the manufacture of a host of modern electronics, including flat-screen
TVs, iPhones, computer chips-and thin-film solar panels, the latest (and
cheapest) generation of solar photovoltaics. (Time named the panels one
of the best inventions of 2008.) Because industry estimates suggested
that only about 2 percent of NF3 ever made it into the atmosphere, the
chemical has been marketed as a cleaner alternative to other
higher-emitting options. For the past decade, the U.S. Environmental
Protection Agency has actively encouraged its use. NF3 also wasn't
deemed dangerous enough to be covered by the Kyoto Protocol, making it
an attractive substitute for companies and signatory countries eager to
lower their emissions footprints.

It turns out that NF3 might not be so green after all. "NF3 has a
potential greenhouse impact larger than ... even that of the world's
largest coal-fired power plants," according to a June 2008 study by
researchers at the University of California, Irvine. Because NF3 isn't
covered by Kyoto, few attempts have been made to measure it in the
atmosphere. But last October, scientists at the Scripps Institution of
Oceanography reported that four times more NF3 is present in the
atmosphere than industry estimates suggest, and its concentration is
rising 11 percent a year.

Compared with the damage caused by CO2 emissions, NF3 remains a blip
because far less of it is emitted. But Ray Weiss, who led the Scripps
team, thinks that, unless regulations require more complete greenhouse
gas measurements, more unpleasant surprises will be in store. With NF3,
he says, "We're finding considerably more in the atmosphere than was
expected. This [gas] won't be the only example of that."

Excuse my ignorance.......

there was an article in Sunday's Dallas Morning News about "solar panels
causing greenhouse gases" due to nsf3 (nfs?) used in cleaning contacts
during manufacturing. Paper already on way to recycle bin, can't bring
it up on their website. Can anyone enlighten me so as to have bullets to
shoot down this latest round of uninformed reporting?
