Yves Ryckmans graduated from the University of Louvain-la-Neuve, Belgium, and conducted a PhD study at the same university on modeling heat transfer in furnaces by finite elements techniques. In 1989, he joined Laborelec, research Centre of ENGIE Electrabel, as a research engineer in the field of nuclear energy. From 1996 on, he initiated the development of fixed bed gasification and CFB gasification of wood through several Belgian and European projects. In 1999 he became Head of the Biomass Competence Centre at Laborelec. This competence centre covers more than 20 years of working on technical issues like co-firing biomass in pulverized coal power plants, biomass gasification, biomass fuel quality, biogas applications, torrefaction, biomass sustainability assessment and LCA studies. His R&D efforts were focused on CFD modeling of PC boilers, slagging and fouling, NOx and SOx emissions, biomass milling and upgrading, ESP, ash quality and utilization, as well as the verification of sustainability criteria for solid biomass. Currently, Yves Ryckmans is Chief Technology Officer Biomass at Laborelec and board member of AEBIOM (European Biomass Association). As such, he is managing research and services for bio-energy applications within ENGIE Group.
