Wood-fired small- and
medium-scale combined heat and power (CHP) plants are a proven technology for
producing domestic, carbon-neutral heat and power. Hydrothermal carbonization
(HTC) is a promising conversion technology for producing an improved, more
versatile wood fuel. By integrating the HTC and CHP processes, the HTC process
can be notably simplified. This study compares six different integration
schemes to non-integrated plants. The overall energy conversion efficiencies were
similar in all six schemes, but there were differences in power output and in
plant complexity, and thus likely differences in investment cost and
operability. The most promising cases were evaluated at varying HTC
temperatures. This comparison showed that temperatures over 220 °C became
problematic for the simpler heat recovery schemes, which resulted in poor
