Reference product: heat, central or small-scale, other than natural gas [MJ]
Location: CA-QC - Canada, Québec
This dataset represents the production of electricity and heat from a biogas mix from different sources (biowaste, sewage sludge) when burning it in a cogeneration unit with gas engine. It is intended to represent the production of grid-connected electricity with biogas. The main product is then considered to be electricity at high voltage, while heat is produced as a co-product. The cogeneration unit has a capacity of 160 kWel; the degrees of efficiency are as follows: electricity: 0.37 and heat: 0.53. A mix of biogas is treated in this dataset with an average lower heating value of 22.73 MJ/Nm3.
[This dataset has been generated using the system model "Allocation, cut-off by classification". A system model describes how activity datasets are linked to form product systems. The allocation cut-off system model subdivides multi-product activities by allocation, based on a physical properties, economic, mass or other properties. By-products of waste treatment processes are cut-off, as are all by-products classified as recyclable. Markets in this model include all activities in proportion to their current production volume.
Version 3 of the ecoinvent database offers three system models to choose from. For more information, please visit: https://www.ecoinvent.org/database/system-models-in-ecoinvent-3/system-models-in-ecoinvent-3.html)]
