Enzymatic fermentation with CCUS (sugar and starch bioethanol)
8
Technology Description
During the fermentation step, a pure stream of CO2 is emitted that can be captured and compressed at relatively low cost due to the high purity of the stream. As the captured CO2 is biogenic, it can provide negative emissions if it is subsequently stored. This can help offset CO2 emissions in other parts of the energy system. See non-CCUS variant for more detail.
Relevance for Net Zero
Conventional ethanol with the addition of carbon capture and storage still plays a role in a net zero world to help decarbonise transport while providing negative emissions. However, its role is limited by its use of agricultural crops that compete with food production.
