Two Main Reasons for High Yield of Ethanol from Miscanthus

A longer growing season and superior photosynthetic efficiency contribute to Miscanthus' high yield

It makes green leaves 6 weeks earlier in the growing season and keeps them until late October. Corn leaves typically wither by the end of August. While it shares a similar growing season, switchgrass is much less efficient at photosynthesis; Miscanthus has a conversion efficiency of around 1%.

Like many perennial grasses, Miscanthus can be grown in poor quality soil and can store a lot of carbon dioxide making it close to carbon neutral.
