Technology Roadmap Sections and Deliverables

Our technology roadmap identifier is shown as:

• 2BSSAF - Brazil Solution - Sustainable Aviation Fuel

This indicates that we are dealing with a “level 2” roadmap at the product level, where “level 1” would indicate a market level roadmap, "level 2" would indicate our SAF Production and “level 3” or “level 4” would indicate an individual technology roadmap.

Roadmap Overview

Sustainable aviation fuel (SAF) offers a promising solution for reducing the aviation industry’s carbon footprint, but scaling its production to meet global demand presents significant challenges. Brazil is often referred to as the “Saudi Arabia of sustainable fuels” due to its significant potential and advancements in renewable energy.

This roadmap explores the dilemma of SAF scalability, focusing on two critical aspects: availability and affordability. The feedstock supply and production capacity is analyzed within the country, and innovative strategies are proposed to enhance scalability. Additionally, economic competitiveness of SAF will be evaluated and compared to conventional jet fuel, considering factors such as production costs, market incentives, and policy support in Brazil.
