From what I can make out, the whole point of this method is that by using catalysts, fossil fuels will no longer have to be involved.
What is the "catalyst" and how much fossil fuel energy is required to produce the "catalyst"?
According to the
abstract, the mediator is silicotungstic acid, and the catalyst is platinum, if that's of any help in figuring out the details. Assuming the catalyst doesn't 'wear out' in any way, it would be a one-off production cost.
