Fuel cells and Plat.
-->July 5 - Financial Times (James Mackintosh and Kevin Morrison ): “The car industry is preparing for the day when oil wells run dry by investing billions of dollars to develop clean and efficient hydrogen-powered vehicles. But the new fuel comes with its own built-in commodity crisis. Today’s experimental hydrogen fuel cells use so much platinum that there is not enough of the precious metal to replace all the world’s petrol engines. As Kazuo Okamoto, the new head of research and development at Toyota, Japan's biggest carmaker, says: ‘With the current type of technology we know already that [platinum supplies] will not be sufficient.’ …At the current 60g or so of platinum in each fuel cell, the world’s 780m cars and trucks would use 46,800 tons of the metal - just below the 47,570 tons estimated to be still in the ground.”
