Akermin, a St. Louis developer of new biocatalytic enzymes, raised $5 million in a second tranche of its first funding round. Investors included Prolog Ventures, OnPoint Technologies, Chrysalix Energy and the St. Louis Arch Angels.
Akermin works with catalytic enzymes — molecules that speed particular chemical reactions — developed with biotechnology that could replace precious-metal catalysts now used in fuel cells. The company is developing prototype “biofuel cells” and thin-fuel cells the company refers to as “bio-batteries.” Enzymes should theoretically be cheaper and more environmentally friendly than metal catalysts.
Fuel cells, which could theoretically replace conventional batteries and engines in some applications, are one of those clean technologies that have been on the table for decades in one form or another. However, existing technologies generally aren’t considered cost- or energy-effective when compared to burning fossil fuels or using traditional batteries.
Akermin is part of a wave of startups working on overcoming the difficulties in making fuel cells. Another is Bloom Energy, a secretive Silicon Valley startup that has nevertheless received plenty of press.
Akermin’s technology is a polymer “stabilizer” for these enzymes that’s designed to immobilize them, stabilize them and enhance their operating lifetime. The company has raised a total of just under $8.5 million since its founding.
