There are promising technology developments leading to sugar industries interest in Brazil, Cuba and other sugar producing countries. The complementarity of biomass gasification systems with natural gas was highlighted in several papers. Small systems Reciprocating engines are approaching the commercial stage. Further work is needed on turbo charge, on catalysts and on load following. Microturbines look promising.
Further work is needed on flameless combustion.
Stirling engines finally look good. More demonstration and long term testing is needed. Large systems Gas turbines are commercial. There is a need to optimise the configuration. Gas engines are approaching the commercial stage.
