1. A biomass conversion system comprising:
a syngas gasifier which outputs syngas from an input of biomass and air;
a cyclone for receiving the output syngas, removing tar and charcoal from the received syngas, and outputting fuel;
a fuel mixer for receiving the output fuel and an input of compressed air and mixing the output fuel and the input of compressed air to generate a mixed stream;
a homogenous charge compression ignition engine for receiving the mixed stream, the homogenous charge compression ignition engine generating brake power using the mixed stream and passing homogenous charge compression ignition engine exhaust to a catalytic converter which outputs the homogenous charge compression ignition engine exhaust;
a turbine which receives the output homogenous charge compression ignition engine exhaust, generates power to drive a turbocharger, and outputs turbine exhaust;
a regenerator which receives the output turbine exhaust and outputs regenerated turbine exhaust;
a first compressor which receives power from the turbine and receives an input of ambient air and outputs the compressed air to said regenerator;
a boiler which receives the output regenerated turbine exhaust, the boiler heating up CO2 and outputting the heated up CO2;
an expander that receives the heated up CO2 and produces power; and
a second compressor that receives the power from the expander to drive a trans-critical CO2 refrigeration cycle therein to produce cooling in a first cooling temperature range, to produce cooling in a second cooling temperature range, and to output boiler exhaust.
