Apparatuses, systems, and associated methods relate to actively cooling and transporting a fuel to a gasification reactor vessel. An actively cooled gasifier screw feeder can include a screw feeder having a first coolant path arranged therethrough and arranged to actively transport the fuel, a sleeve arranged in coaxial relation and about the screw feeder having a second coolant path arranged therethrough, a coolant reservoir arranged to receive, store, and supply a coolant to the first and second coolant paths, and a coolant pump in operative communication with the coolant reservoir and arranged to pump the coolant. The actively cooled gasifier screw feeder is configured to actively cool and feed the fuel into the gasification reactor vessel at a fuel feed rate based upon a type of the fuel and during steady-state operation of the gasification reactor vessel.

Combining multiple subsystems involving biomass processing, biomass gasification of the processed biomass where a synthesis gas is produced then converted to hydrogen fuels or other transportation fuels for use in coupled transportation systems sized to consume all the transportation fuel produced. Carbon in the biomass is converted to CO.sub.2 in the conversion process and a portion of that CO.sub.2 is captured and sequestrated for long term storage.
