Zero-Waste CO2 to Sustainable Aviation Fuel Production via Micro-Algae

transportPilotedTRL 5

Imagine using tiny water plants to eat CO2 and breathe out a gas that can be turned into jet fuel. Instead of expensive farming and squeezing oil from algae, this method lets the fuel precursor simply evaporate from the cells. To make it even better, the leftover plant material is turned into food thickeners and hydrogen gas so nothing goes to waste.

The business problem

What needed solving

Sustainable aviation fuels are currently too expensive and inefficient to produce at scale. Traditional algal fuels require costly harvesting and drying processes that make them commercially unviable.

The solution

What was built

A production process for isoprene (a fuel precursor) using cyanobacteria and a solar-driven photochemical upgrade system to create jet fuel molecules.

Business applications

Who can put this to work

Aviation
enterprise
Target: Airline or Airport Fuel Supplier

If you are a fuel supplier dealing with strict carbon emission mandates — this project developed a way to produce jet fuel from CO2 that avoids expensive harvesting and drying steps. This reduces the overall cost of sustainable aviation fuels (SAF).

Food Processing
mid-size
Target: Food Ingredient Manufacturer

If you are a food company dealing with the need for sustainable additives — this project developed a zero-waste biorefinery that co-produces starch from micro-algae. This starch can be used as a thickener or filler in food products.

Industrial Gas
enterprise
Target: Hydrogen Production Plant

If you are a gas producer dealing with the high cost of green hydrogen — this project developed a system that co-produces hydrogen indirectly from CO2. This allows for a diversified revenue stream alongside fuel production.

Frequently asked

Quick answers

How does this technology reduce the cost of sustainable aviation fuel?

It produces a volatile precursor called isoprene, which eliminates the need for expensive downstream processing like harvesting, drying, and lipid extraction.

At what scale has the technology been proven?

The project has demonstrated a productivity of >50 mg isoprene L-1 day-1 at lab scale (TRL 4) and aims to reach TRL 5 through pilot scale trials.

What is the intellectual property or licensing status?

Based on available project data, specific patent or licensing terms are not listed, but the project involves 14 partners including 6 industrial entities.

How is the fuel quality verified?

The produced molecules are evaluated against ASTM standards to ensure they meet aviation requirements.

When will this be ready for industrial use?

The project runs from 2024-01-01 to 2027-12-31, targeting a TRL 5 pilot scale by the end of the period.

Consortium

Who built it

The project is highly market-oriented with a 43% industry ratio, comprising 6 industrial partners and 5 SMEs. With 14 partners across 8 European countries, the consortium balances academic research (6 universities, 2 research centers) with practical application, ensuring the technology is developed with end-user requirements in mind.
