11 | Doris Hafenbradl — CTO & Managing Director, Electrochaea

🦠 You've heard of two major domains of life: Bacteria (think E. coli) and Eukaryotes (like yeast, plants, animals, etc). Do you know what the third major domain is? (Hint: it's hidden in the company name, Electrochaea.) Do you know how it stores energy? Tune into this episode where Doris Hafenbradl joins BioZen's CEO Nate Kirchhofer to discuss these ancient microorganisms—the biocatalysts at the heart of Electrochaea's technology. Their process uses renewably-sourced hydrogen gas (H2) from electrolysis to convert waste carbon dioxide (CO2) into stored energy in the C-H chemical bonds of bio-generated methane molecules (CH4). The discussion ranges across the scalability, intermittency tolerance, and global manufacturing benefits of this approach; details of Electrochaea's 1, 10, 25, and 75 MW reactor scales; the path to converting 3M tonnes of CO2 to CH4 (equivalent of 50+ TWh capacity!) by 2030; how bio-methane integrates into existing infrastructure; and even a little advice for the renewable energy technologists out there.
