The aim of ALFAFUELS is to reduce reliance on fossil fuels, mitigate climate change, and enhance aviation’s environmental sustainability through innovative technologies such as microbial production and photochemical CO₂ conversion.


To face high production costs, sustainability issues, and technological constraints, ALFAFUELS will develop three technological innovations:

Microbial Production

This approach involves using microorganisms to convert CO₂ into a fuel precursor. Microorganisms perform this process sustainably, which means it has a lower environmental impact.

Solar-Powered Photochemistry

In this method, the energy of the sun is harnessed to convert CO₂-derived molecules into kerosene-like fuel. Instead of using conventional chemical methods, which can be costly and less environmentally friendly, this technique uses solar light to carry out the conversion.

Biorefinery Approach

Rather than wasting any part of the cells of microorganisms used in the process, all parts are used efficiently. This includes the production of starch and hydrogen indirectly from CO₂. In summary, resources are maximised, and waste is reduced.

The project will play a key role in decarbonising the aviation industry by providing a sustainable alternative to conventional fuels, reducing greenhouse gas emissions associated with flights.

By capturing and using CO2 directly in Sustainable Aviation Fuels (SAF) production, ALFAFUELS contributes to climate change mitigation, reducing reliance on fossil fuels in favor of renewable carbon sources.

ALFAFUELS stands out for developing innovative and sustainable technological solutions at every stage of the SAF production process, enhancing overall efficiency and sustainability in the aviation value chain.

Applying a circular and zero-waste approach, the project maximises resource efficiency by valorising all cellular components in a biorefinery, co-producing valuable products like starch and hydrogen from CO2.

ALFAFUELS aims to lower production costs by minimising raw material expenses, optimizing process efficiency, and incorporating innovative technologies, contributing to the long-term economic viability of sustainable aviation fuels.


ALFAFUELS employs a comprehensive methodology for advancing sustainable aviation fuel (SAF) production. Starting with metabolic modeling, the project identifies strategies for converting CO₂ and H₂O to jet fuel precursors using cyanobacteria and microalgae. The isoprene is then upgraded to jet fuels through innovative photo-chemical routes. The methodology follows a zero-waste, circular approach, valorizing all cell components. Optimisation is achieved through kinetic and process modeling, leading to the design of bioreactors for isoprene production. Experimental data is used for combined Life Cycle and Technoeconomic assessments. The project includes a market uptake analysis in the EU's pathway to net zero, ensuring alignment with end-users and reaching Technology Readiness Level 5 (TRL5).


AddScience Sweden AB conducts contract research and development, analytical and consulting services for industry and society, as well as public research with a focus on sustainable transition and bio-based products. AddScience specializes in chemical problem solving in the material, product and process areas, where we combine our knowledge and experience with both classical and state of the art analytical chemistry tools, such as GC-MS, in-house designed instruments and test rigs. Areas that we have worked in in the past with both problem solving and development are e.g. electronics, chemical processes, surface treatment, medical technology, quality monitoring, product durability/lifetime, food, water treatment, material emissions, biogas, recycling and algae cultivation.  AddScience shares the Industridoktorn® trademark with four additional companies in the area of chemistry and microbiology, operating out of newly built laboratory premises on Björkö in the northern archipelago of Gothenburg, Sweden.
