Hydrothermal carbonization (HTC) is a new variation (biomass conversion) of an old field (biofuel) that has recently been further developed by workers in Germany.[1] It involves moderate temperatures and pressures over an aqueous solution of biomass in a dilute acid for several hours. The resulting matter reportedly captures 100% of the carbon in a "biocoal" powder that could provide feedsource for soil amendment (similar to biochar) and further studies in economic nanomaterial production.[2]
