A combined photobiological/photochemical production platform for sustainable solar jetfuels from CO2

Direct conversion of solar energy and CO2 to a fuel can contribute to the transition to fossil free aviation. We propose a system for converting CO2 directly to jet fuel through a combined photobiological/photochemical process, which will be optimized at pilot scale to produce 100% sustainable and carbon negative jet fuels, mitigating, at the same time, industrial GHG emissions.

The concept is based on a novel process, recently invented by us, where cyanobacteria produce small volatile hydrocarbons. Through a photochemical dimerization and subsequent hydrogenation, a clean, kerosene-type fuel is obtained which fulfills the criteria for use as jet fuel.

In this project, we will evaluate simulated industrial conditions for cyanobacteria growth, and we will develop improved strains regarding yields and productivities. We will scale up the cultivation technology, establish continuous product recovery at pilot scale and develop new reactors for the photochemical step.
