The most odd thing about all these forecasts is that they all imply that the loading of iridium in electrolysers will be decreased by an order of magnitude and that recovery rates will be "greater than 90%". The chances of both these events occuring within our lifetimes are slim. In my expereince reducing the loading down to trace levels makes the recovery and cost of recovery especially for Ir too difficult. The Ir price will be too high to justify its use in electrolysers (coupled with high electricity prices) any hydrogen thus will be prepared from oil/gas. There needs to be an end to all this greenwashing..
