I added the 96% to the title here on HN intentionally, because it says here in the abstract "We convert highly concentrated bicarbonate solution to solid formate fuel with a yield (carbon efficiency) of greater than 96%" Neither MIT Press nor the ScholarlyArticle authors asked or paid me to modify the headline to cite the carbon efficiency. This capability is arguably better than everything else we do for energy; it is 96% carbon efficient. Other stats for comparison of such methods are proposed herein?
