Ir. Harrie Knoef

It’s my believe that there is a bright future for biomass gasification, especially at the smaller scale worldwide. There is a tremendous amount of biomass residues available for energy generation purposes like heat, power or biomass based materials but also for essential products like chemicals. I am passionate about biomass gasification, about innovations in that area and like to assist SME’s to guide them towards innovative biomass energy projects. When fossil fuels become depleted or too expensive, the only viable renewable technology will be biomass as it contains the most important chemical compound Carbon.
