Ford
System Turns Paint Exhaust Into Power

DEARBORN, Mich., July 18, 2003 --
Can paint exhaust be turned into an inexhaustible source of clean electric
power? Absolutely, say Ford Motor Company and Detroit Edison, who have jointly
developed a new Fumes-to-Fuel system that instead of burning paint fumes, turns
them into hydrogen fuel for fuel cells.
Installed in the Paint Shop of the
Ford Rouge Center, the pilot system captures the volatile organic compounds –
or VOCs – found in paint fumes, and concentrates them into a rich mixture of
hydrocarbons, which are a source of fuel. The mixture then is fed into a
reformer that turns it into a hydrogen-rich gas. From there, the gas is fed
into a stack of solid oxide fuel cells, where a chemical reaction between
hydrogen and oxygen, creates electricity, water vapor and an insignificant
amount of carbon dioxide.
"For years, we've been taking
the fumes coming out of paint booths and incinerating them to protect air
quality. Now we have a system that can do that even more efficiently, produce
clean electricity and allow us to improve paint shop flexibility. It's almost
too good to be true," said Jay Richardson, Ford Rouge Center redevelopment
manager, and former Ford paint engineer.
Patented by Detroit Edison in the
United States, and internationally by Ford and Edison, the new system is
expected to generate a great deal of interest, in addition to electricity. The
Ford Rouge Center Paint Shop pilot generates about 5,000 watts of electricity –
enough to power an average home. A larger Fumes-to-Fuel system, to be installed
in 2004, will have the capacity to generate more than 100,000 watts.

"We looked at a lot of
alternative energy proposals, but none of them made business sense," said
Tim O'Brien, Ford Motor Company vice president, Corporate Relations. "We
planned a fuel cell demonstration project to gain experience with the
technology, but when Ford and DTE engineers proposed the Fumes-for-Fuel
project, we jumped on it. It really demonstrates the ability to come out with a
sustainable business solution that improves the environment by substantially
improving emissions, improves business by reducing fuel costs for incineration
and actually generates usable energy from a waste product."
"When fully developed, this
system has the potential to save Ford millions of dollars by reducing the cost
of incinerating paint fumes in natural gas-fired furnaces, as we do now,"
explains Mark Wherret, the Fumes-to-Fuel System project leader and principal
environmental engineer, Ford Environmental Quality Office. "It will also
cost much less to install and maintain, virtually eliminate carbon dioxide
emissions, and enable us to continue using solvent-based paints which produce a
better quality finish than powder or water-based paints."
Patrick Ryan, a Detroit Edison
engineer, collaborated with Wherrett on development of the Fumes-to-Fuel
System. Ryan is one of nine engineers employed by the utility, who work
exclusively for Ford Motor Co., to help the automaker maximize energy
efficiency in its operations. "The Fumes-to-Fuel System is an excellent
example of how, using good engineering, industry can find environmentally
friendly solutions that also are good for business," Ryan said.
"Detroit Edison has found that
by working as a partner with our customers, everyone shares in the benefits of
technological innovation and the efficient use of energy," said Robert J.
Buckler, President and Chief Operating Officer of DTE Energy Distribution,
which operates Detroit Edison. "Providing an on-site energy management
team to major industrial companies helps those customers control costs and use
energy more efficiently. This project demonstrates that these partnerships also
can contribute to a cleaner environment for everyone."
While engineers and scientists in
Ford's Environmental Quality Office and Scientific Research Laboratories,
developed, tested, and successfully installed the Fumes-to-Fuel System pilot,
the project is the result of a collaborative effort between several entities,
including Ford, Detroit Edison, Fuel Cell Technologies, Ltd. of Kingston, Ont.,
Climate Technologies, and the State of Michigan (Public Service Commission),
which provided partial funding for the project through its Energy Efficiency
Grant Program.
