EUBCE 2024 - Beethoven NARVÁEZ-ROMO - Decarbonization of Fossil Jet Fuel Production Using Low-Carbon Hydrogen

Decarbonization of Fossil Jet Fuel Production Using Low-Carbon Hydrogen

Short Introductive summary

The average production of jet fuel from a barrel is 4% of the total oil barrel feed in the process, 6.36 liters, and has an average consumption of 890 Nm3 H2. Solutions that integrate low-carbon emissions along with conventional fossil processes are required to achieve real and progressive decarbonization transition, especially in the energy heavy-to-abate sector. Therefore, the current study aims to estimate the technical potential of decarbonization of conventional jet fuel production implementing low-carbon H2. As a methodological approach, the carbon intensity of the conventional jet fuel production was defined as a greenhouse gas (GHG) emission baseline, CO2-eq. Then, the low-carbon H2 production becoming from bio-ethanol, ethanol steam reforming (ESR) pathway, was investigated. Moreover, low-carbon H2 production pathways, such as water electrolysis powered by wind and photovoltaic solar energy, were compared. Results showcased that substituting fossil H2 with low-carbon H2 for jet fuel production reduced GHG emissions from 148.2 to 59.3 kgCO2 per kg of jet fuel when the ESR pathway was employed.
