That would result in a pure stream of CO2, he said, avoiding the two-thirds of CCS\’s cost, which is incurred in separating the gas. Another cost-cutter could be using the CO2 to grow algae, which is then used as animal feed.
Of course, I don\’t say that just because such fuel cells would be likely to use my beloved scandium….
