    Technologies utilizing carbon-dioxide (CO2) as a feedstock to generate valuable products will play a key role in turning the chemical industry onto a more sustainable path. This project addresses the efficient utilization of solar energy and CO2 by introducing a novel technology to produces base chemicals and fuels from non-fossil fuel resources, using an original device architectures for the direct photoelectrochemical (PEC) conversion of CO2 and H2O. During my ERC Starting Grant project we have identified 4 different approaches for PEC CO2 reduction: (i) direct PEC reduction (photocathode), (ii) direct PEC oxidation (photoanode), (iii) PEC reduction and oxidation (photocathode+photoanode tandem), (iv) buried light absorber + EC. In all cases we focus on membrane separated, zero-gap cells, where humidified CO2 can be used as input. This approach will open the opportunity to use industrial exhaust fume (rich in both CO2 and H2O) directly as feedstock for the generation of valuable chemicals. There are four main objectives of this project, which together ultimately result in a preliminary business plan and a roadmap to move PEC_flow cells to commercialization. These are to (i) Validate laboratory results from the ERC HybridSolarFuels Starting Grant, obtain operational parameters under realistic conditions, which can be used in modelling. (ii) Perform technoeconomic and life cycle analysis to select the optimal PEC cell configuration for future activities. (iii) Clarify IPR position and carry out market analysis (including stakeholder- and competitor analysis). (iv) Based on all the above, develop a business plan, which paves the road for future activities, ultimately leading to commercialization.

    To be the first CO2-neutral continent by 2050, Europe needs to develop and implement disruptive new technologies, based on scientific breakthroughs. In this regard, utilization of CO2 and organic waste as feedstock to generate valuable products will play a key role in turning the chemical industry on a more sustainable, circular path. In the SunFlower project, we are going to demonstrate that two high-value processes (CO2 or CO reduction and glycerol oxidation will be studied first) can be synergistically coupled to produce chemicals (such as ethylene and lactic acid) and fuels, using novel photoelectrode assemblies (both photocathodes and photoanodes), original photoelectrochemical (PEC) device architectures, and automated processes. The SunFlower project is based on the following three hypotheses: 1. Proper engineering of continuous-flow PEC cells operating under concentrated sunlight will allow current densities similar to the electrochemical (EC) methods. 2. One semiconductor alone can supply the necessary energy input for bias-free operation of PEC cells, while generating two high-value products. 3. PEC methods can provide superior selectivity compared to their EC counterparts, even at high current density operation (as the current density and potential can be decoupled). To validate our hypotheses, we are going to use for the first time: • The pairing of two high-value generating redox processes (none of them being H2 or O2 evolution). • Concentrated sunlight (which has only been used for water-splitting so far). • Custom-designed and developed PEC cells, elaborating on the photo-gas diffusion electrode concept. • Machine learning, based on the broad dataset collected by the sensors built in the PEC system, optimizing the performance at a system level. The proposed combination of these novel approaches will be of groundbreaking nature, therefore, it opens a whole new arena of solar energy conversion.
