Carbon dioxide from fermentation can be captured at a relatively low cost (about $15-35 /tonne**), requiring only dehydration and compression. Unlike other CO2point sources, ethanol production generates a high purity (99%) stream of fermentation CO2 containing only CO2, H2O. Total abatement cost is about $50/tonne.

𝙋𝙧𝙤𝙭𝙞𝙢𝙞𝙩𝙮 𝙩𝙤 𝙍𝙖𝙬 𝙈𝙖𝙩𝙚𝙧𝙞𝙖𝙡: U.S. ethanol plants (Midwest) are typically located close to the raw material. The map below shows U.S. ethanol production facilities from CaptureMap, counting 168 sites and 19.3 MtCO2e per annum.

𝙁𝙞𝙣𝙖𝙣𝙘𝙞𝙖𝙡 𝙄𝙣𝙘𝙚𝙣𝙩𝙞𝙫𝙚𝙨: 45Q ($80/t-Saline Aquifer Injection; $50-EOR); LCFS ~$71/ton.

𝙋𝙧𝙤𝙫𝙚𝙣 𝙏𝙚𝙘𝙝𝙣𝙤𝙡𝙤𝙜𝙮: The technical feasibility of fermentation CCS and permanent geologic storage in saline aquifers has been demonstrated at one U.S. site owned by ADM where captured CO2 was sequestered in the Mt. Simon Sandstone formation:
