Besides just electricity and heat, CertiQ also certifies a combination of heat-generated electricity from renewable sources. In practice, these are installations that use biomass. An example is a fermentation plant where electricity is produced with one or more gas engines, and the generated heat is utilized appropriately. The Guarantees of Origin (GoOs) we provide digitally are the only valid proof in the Netherlands that the energy has been durable sustained. In case of a grant decision, CertiQ provides the necessary information to the 'Rijksdienst voor Ondernemend Nederland' (RVO).
