Tittel

Impact of the CO2 factor of electricity and the external CO2 compensation price on zero emission neighborhoods’ energy system design

Sammendrag

Existing literature on Zero Emission Neighborhoods(ZENs) and Buildings (ZEBs) only allow for reaching the zero emission target locally. This paper evaluates the impact of allowing to buy CO2 compensation to reach that target in the design of ZENs. This is motivated by questions regarding the relevance of investing in local renewable production (mainly from PV) in a power system dominated by renewable hydropower.Further, it contributes to the existing literature regarding ZENs and ZEBs by highlighting the importance of the choice of the CO2 factor of electricity for the design of ZENs’ energy system. A case study illustrates the impact of those choices on the resulting energy system design using the existing ZENIT model.Three CO2 factors for electricity are used in the case study:a yearly average CO2 factor for Norway (18gCO2/kWh), an hourly average CO2 factor for Norway and a yearly average European factor (at 132gCO2/kWh). The energy system design of the ZEN is little affected when using hourly CO2-factors compared to yearly average factors, while the European factor leads to less investment in PV. Hourly marginal CO2 emission factors are also investigated using three accounting methods. There are large differences in energy system design and emissions depending on where the factor is applied. The price of external compensation is varied between 0-2000e/tonCO2. A lower price of external CO2 compensations mainly reduces the amount of PV investment. Allowing the purchase of CO2 compensations at 250e/tonCO2 could reduce the total costs by more than 10%.
