Capture solar energy
Cyanobacteria use sunlight to split water, releasing electrons, protons and oxygen.
EIC Pathfinder · A European research consortium
Photosynthetic electron focusing technology for direct efficient biohydrogen production from solar energy
We’re engineering photosynthetic bacteria to create a new route from sunlight and water to clean, renewable fuel.
The idea
Photosynthesis powers life. PhotoSynH2 brings together synthetic biology, enzyme engineering and photobioreactor design to direct that energy towards hydrogen.
Cyanobacteria use sunlight to split water, releasing electrons, protons and oxygen.
Engineered biological systems aim to redirect electrons towards hydrogen production while managing oxygen inhibition.
Hydrogenase enzymes and contained photobioreactors bring the biological route closer to practical energy production.

From cells to systems
Our work starts with Synechocystis, a well-studied cyanobacterium, and connects molecular engineering to the demands of cultivation and scale.
The consortium
Six partners connect fundamental research with engineering and industrial know-how. The project is coordinated by Alfonso Jaramillo at CSIC’s i2SysBio.
