The Costliness of Catalysts
To date, the use of PGM catalysts have made the up-front cost of fuel cells and the refurbishment of the devices over their life far too expensive to be widely adopted, but Acal Energy in the UK has developed a low-cost liquid catalyst that can be continuously regenerated, dramatically reducing the up-front and life-cycle costs.
Meanwhile, ITM Power has developed a hydrogen-fuel-generating unit that is entirely safe contained except for a supply of electricity and water. Ben Graziano, technology commercialization manager at the Carbon Trust, said between them the two technologies could help the industry be worth up to $1 billion in the UK and $26 billion globally by 2020, and up to $19 billion in the UK and $180 billion globally by 2050.
Grandstanding? Yes, probably, but the prize of affordable, low-emissions power is so valuable, maybe we can forgive the hyperbole. Fuel-cell automobiles and power generators for homes and businesses have far greater credibility than electric cars and windmills — if they can be brought to market at comparable cost.
I, for one, would sooner see my hard-earned tax receipts spent subsidizing (if they have to be spent in such a way) fuel cells that will allow me to travel longer distances, quietly, without emitting more than heat and water vapor, and with the prospect of 5-minute-stop refueling stations at the same location as current filling stations, rather than subsidizing electric cars that can’t do more than about 80 miles between re-charges and precious few charging points being available — even within cities, never mind in the countryside.
The numbers have yet to support the hype, but although we’re metals nerds, we say that if replacing PGMs by non-metallic compounds is the step that finally brings fuel cells to commercial reality, then we’ll see that as a welcome outcome.
