This application relates to the demonstration of the Torrgreen and Torrpower installations. The Torrgreen installation is a mobile torrefaction installation. The Torrpower installation is also a mobile installation, for the gasification of torreficated bio-raw materials and the generation of heat and electricity. The aim is to demonstrate the installations under real conditions, at Cirwinn in Almere. This is necessary to bring the installations to the market and to be able to scale up, at national and international level. The demonstration demonstrates the versatility of torrefaction technology, through its ability to transform various bio-raw materials, including herbaceous biomass and woody bio-raw materials, into a homogeneous energy carrier, the torrrpellets. The demonstration also shows that Torrgreen can then convert it into heat and electricity in the high-efficiency Torrpower installation, at a cost that is competitive with fossil energy sources.
