Abstract
Here we evaluated Fischer Tropsch-diesel (FT-diesel) use in heavy-duty trucks based on various production pathways differing in the CO2 and H2 provenance. To better understand the global environmental implications of fuelling heavy-duty trucks (HD trucks) with FT-diesel, we quantified environmental impacts over the entire life cycle using seven Planetary Boundaries (PBs) regulating the Earth's resilience. Our environmental assessment follows a well-to-wheel scope with the functional unit based on the global annual freight demand. The baseline scenario corresponds to the conventional fossil fuel. Our results show that the fossil fuel alternative is unsustainable as it transgresses the climate change PBs. Using FT-diesel based on captured CO2 could help operate within the safe operating space but it could induce critical burden-shifting if the CO2 and H2 sources are not adequately selected.
