Hydrothermal carbonization, or HTC, takes advantage of water’s changing properties at elevated temperature and pressure. When water is in the region of its supercritical point of 374°C (705°F), 22.1 MPa (3200 PSI), it becomes a highly active organic solvent. In this state it easily breaks down organic compounds, including cellulose and lignin. Although using this process can lead to the production of other alternative fuels, biocarbon is the easiest and least expensive to produce, the least complex, and the easiest to transport.
