Gold will play major part as well.

ferent technologies.

Asian companies are producing gold catalysts, as is US company 3M, a large manufacturer of gas masks.

Interestingly, gold catalysts may well be able to work hand in glove with their precious-metal platinum cousins in the fuel cells arena, where the potential is seen as sizeable.

Gold catalysts are able to remove the CO in hydrogen streams used in fuel cells, but work still has to be done on deactivation issues.

Should the hydrogen economy become a reality and gold be used as a guard bed to remove CO, the offtake of gold catalysts could be significant.

Gold is already being used to meet the most stringent European Euro-5 emission targets, with certified gold catalysts having been fixed to thousands of diesel-powered vehicles.

On the whole, however, it is platinum that enjoys the lion’s share of the emission-reduction business because the melting point of platinum is far higher than the melting point of gold.

While gold starts underperforming at 350 ºC, platinum is successful even beyond 1 000 ºC.
