Abstract: The system of biomass integrated gasification combined cycle (BIGCC) has been selected for technology transfer to New Zealand to generate electricity and thermal energy using wood residues. This is due to its advantages of higher electrical efficiency, lower emissions and more flexible ratio of electricity to thermal energy. However, the technology needs to be further developed and improved for commercialisation. This paper reviews and evaluates five BIGCC demonstration projects and a steam gasification project developed overseas to learn their experiences and lessons. A BIGCC system with steam gasification is recommended for technology transfer to New Zealand. The key areas for further research and development are identified to be optimisation of the gasification performance, improvement of gas cleaning technology, optimisation of the system integration, and reduction of capital cost.
