Bioenergy
Bioenergy is derived from crops that harvest the energy in sunlight, carbon from CO2 in the air, and hydrogen from water. The energy is stored in various forms - starch in corn and cellulose, hemicellulose, and lignin in agricultural residues, as well as in soybeans. Fermentation-based processes that convert crop and grain residues into ethanol are the focus of LORRE's research.
