Dynamic LCA to Assess Circularity of Biofuels - Comparing Different Energy Carriers for Trucks
Short Introductive summary
Climate neutrality and circularity are two main challenges and can only be addressed by the methodology of dynamic Life Cycle Assessment (LCA), where GHG emissions, resource demand and material recovery are calculated over the life time from construction, operation until the end of life management. In the Technology Collaboration Program (TCP) of the International Energy Agency (IEA) experts from 20 countries cooperate on LCA of transportation systems since 2010, where in Task 52 the focus is Circularity assessment of different vehicles and its components. A total new methodological framework to assess the circularity potential was developed and applied in a case study to compare N2 trucks with different propulsion & fuel combinations: HVO from rape seed, FT-diesel from wood, diesel and renewable electricity for hydrogen, e-diesel and battery electric trucks. Based on the life cycle material flows the Material Circularity Index (MCI) is used to assess the circularity potential (0% - 100%) over the lifetime of the trucks.
