So no Herreshoff Furnaces are used. > It's not clear to me what advantage biocoal batch production via pressurized hydrothermal carbonization would have over continuous char production via fast or slow pyrolysis for the purpose of landfilling or soil amendment. For example, here is a company with a continuous fast pyrolysis process developed to the point of early commercialization, which produces char as well as liquid and gaseous fuels from a variety of feedstocks: http://www.dynamotive.com/ . It would seem to me that char produced by pyrolysis in Ontario would serve the carbon sequestration purpose at least as well as biocoal produced by hydrothermal carbonization in Namibia, no?
