Appendixes Refinery 2050. Summary of scope, safety and air quality, and potential availability for low-carbon feedstocks (Concawe Report 9/19A)

The report 9/19 (Appendixes included in the document 9/19A) is the second in a series of publications that explore opportunities and challenges for EU refineries to integrate technologies and feedstocks that would reduce the fossil carbon intensity of petroleum products.

The first Concawe report (Low Carbon Pathways: CO₂ reduction technologies in the EU refining system. 2030/2050) explored opportunities to invest in new technologies to reduce the CO₂ emissions from refineries in the short and then medium-term. The Concawe 9/19 report goes beyond this approach by exploring the potential to substitute crude oil with bio-feedstocks and the use of renewable electricity. Sustainable vegetable oils, lignocellulosic biomass and e-fuels have been selected as initial examples of key low carbon feedstocks in this conceptual assessment.

As the starting point for this analysis, two potential 2050 demand scenarios are defined, followed by the description of the conversion pathways required for the integration of the selected low-carbon feedstocks within a notional mid-range European refinery. Then, the results of the modelling exercise are presented, moving from mostly oil based cases, where the EU refineries meet the 2050 demand in the most plausible CO₂ efficient manner, to the progressive integration of low-carbon feedstocks illustrated by two series of cases:

• Limited penetration cases (individual pathways): where the implications of the production of 1 Mt/a liquid products from each of the selected low carbon feedstocks are described.
• Maximum low carbon feedstock cases (Combined pathways): Based on the different nature of the feeds explored, this report moves further in the analysis by looking at the combination of different low carbon feedstocks.

In all the cases modelled, the implications in terms of feedstock supply, key processing requirements such as hydrogen and electricity and the impact such changes have on the CO₂ emissions intensity both at refinery level and for the end products in Europe are initially assessed and quantified. Potential impacts and synergies with the existing assets, as crude oil is progressively replaced, are also investigated.
Beyond the main report, the Appendixes included in the present document (Concawe 9/19A) complement the analysis of the main low carbon feedstocks/technologies explored by providing an initial view on:

• the potential implications on air quality and safety
• the potential feedstock availability in Europe (Medium and long term)

As mentioned in the abstract of the main report, this conceptual assessment is not intended to be a roadmap for the whole refining industry. The low-carbon feedstocks explored are selected examples. Multiple additional pathways/feedstocks could be also integrated within the EU refining system subject to the location of the sites and individual company strategies.
