Hydrogen Fuel Cells May Harm Ozone Layer
From Times Staff and Wire Reports
Widespread use of the hydrogen fuel cells that President Bush has featured in his energy plan may not be as environmentally friendly as many believe.
Scientists say the new technology could lead to greater destruction of the ozone layer that protects Earth from cancer-causing ultraviolet rays. Researchers wrote this week in the journal Science that if hydrogen replaced fossil fuels, large amounts of hydrogen would drift into the stratosphere as a result of leakage and indirectly cause increased depletion of the ozone.
