In reply to Daniel Culver’s well considered posting in regard to Gas
Carbon Footprints, properly generated multicell hydrogen/oxygen
generation (like a Spirflame[tm]) has the very best overall gas
carbon footprint when directly compared to piped or bottled gases.
However, this is really an unfair statement. As Daniel suggests, many
factors are not considered when determining the complete footprint
for every technology. Multicell technology uses far less energy to
produce a much larger volume of gas than a common water welder.
However, where does this energy come from? In France there is good
chance the electrical energy (approx. 45 percent) is supplied from
Nuclear Energy, while in America the same volume of energy could
easily be supplied by coal. This would give the Spirflame[tm] in
France a smaller footprint than the Spirflame[tm] in America. And,
since all Spirflames[tm] are made in Switzerland, this might be added
to by the greater shipping distance from Switzerland to America when
compared with Switzerland to France.
Usage itself is an important factor. There is also the concept in
regard to the operational life of the gas generating system and how
much of it is recyclable. Spirflames[tm] even in harsh industrial
applications last a very long time, and are usually upgraded after
many years of use, not replaced as other units must be. We have
specific programs in place for this purpose.
Other considerations in regard to what percentage of a suppliers
firm is involved in renewable energy such as fuel cells and solar
where Spirig (our firm) is deeply involved, and holds a number of
critical patents, as well as being used to manufacture those
As a firm with a carefully considered gas, carbon and environmental
footprint (we consider it one indicator of profit). A firm with
distinct advantages, we still need to state, discussions of a
products “carbon footprint” especially as a selling point can be
inaccurate, perhaps deceptive once all factors are carefully
We prefer to focus on operational benefits which are clearly defined
in direct comparison with other products. How our product improves
your product and makes it easier to produce. It is clear, for many
heat sources, inaccurate or incomplete measures are being stated.
So, for now, we do not use our favorable footprint as an advertised
benefit and will probably not do so until it becomes a more easily
defined and a better measured concept for all. Thank you Daniel
Culver and Peter Rowe for posting not only knowledge, but wisdom
into this interesting subject.
