This workshop is organised in the framework of the projects REUSE [reuse-project.eu] “Enzymatic CO2 capture in a rotating packed bed and electrocatalytic CO2 reduction to useful products” and COSEC [cosec-project.eu] “Biogenic CO2 capture into Sustainable Energy Carriers: A novel photosynthetic and hydrogenotrophic CO2 fixation combined with waste nutrient upcycling for production of carbon negative energy carriers”  

This workshop will serve to present and discuss activities and results of the two European projects REUSE and COSEC aiming to find promising solutions for the capture and valorization of biogenic CO2 through nature-inspired routes. 

REUSE aims to develop an innovative approach to capturing and utilizing CO2 using a Rotating Packed Bed (RPB) system. The RPB employs immobilized Carbonic Anhydrase (CA) enzymes and advanced solvents to efficiently capture CO2 from biogenic flue gases. The captured CO2 is then turned into valuable products like carbon monoxide (CO) or formic acid (FA) through a CO2 reduction (CO2R) cell. The project focuses on using cost-effective and readily available biomass blends optimized for combustion and gasification.  

​​COSEC aims ​     ​​to develop a disruptive, nature-based solution for capturing biogenic CO₂ directly from bioenergy systems and turning it into renewable energy carriers within a truly circular carbon system. Using photosynthetic microorganisms such as microalgae and cyanobacteria, COSEC aims to ​use​ wastewater streams and captures CO₂ and converts it into energy-rich biomass. This biomass is then upgraded into biocrude and biogas, which can be further refined into biofuels and biomethane. In this way, COSEC not only reduces emissions but creates new renewable fuels, closing the carbon loop and increasing the sustainability of the entire bioenergy value chain. The consortium unites leading research institutions and industrial partners, covering every step from CO₂ capture to fuel production, sustainability assessment, and large-scale implementation. By developing a modular, scalable pilot plant, COSEC will demonstrate how its circular solution can be replicated across Europe, especially in regions transitioning away from fossil fuels.​​
