Seasonal solar energy potential and the need for heat and power do not match in Northern and Central European conditions. Consequently, large investments are needed for storing solar energy from summer season to dark winter time. The widely available combined heat and power plants and heating networks should be utilized effectively also in the future energy system. In addition to these challenges, decarbonisation of the transport sector requires massive production of renewable fuels especially for the heavy duty sector: air traffic, ships, heavy duty road vehicles. FLEXCHX project is aiming to present a cost-effective solution to tackle these challenges of the new European energy mix. Principal ideas of the proposal are: - A hybrid process that integrates electrolysis to biomass gasification and synthesis is developed and the key enabling technologies of this process are validated to reach TRL5. - In summer season renewable fuel intermediate (FT-wax) is produced from biomass carbon boosted with solar energ

REWOFUEL goal is to demonstrate the performances, reliability, environmental and socio-economic sustainability of the entire value chain, for the transformation of residual soft-wood into hydrolysate (RWH), conversion of RWH into bio-Isobutene (bio-IBN) by fermentation and further conversion to biofuels. To achieve these goals a team of 11 partners, leaders in their field, originating from 7 EU-member states, will join efforts. REWOFUEL consists in showcasing the value chain, from residual wood to 3 high performance drop-in biofuels derived from bio-IBN. These biofuels are full-bio-ETBE, bio-isooctane and bio-isododecane rich biofuels. This large market is today supplied entirely by products derived from fossil-based IBN. Products derived from bio-based IBN, using the same process as fossil-based IBN, would provide a true renewable alternative. REWOFUEL includes the development & up-scaling of this process and the valorization of coproducts: lignin, microbial biomass, biogas and fertilizers. To this end, four ambitious objectives were defined: -Demonstrate the production of residual wood hydrolysate (RWH) and establish a quality standard to feed the IBN fermentation unit, -Demonstrate the production of bio-IBN-based biofuels from RWH at pre-commercial scale, -Demonstrate the valorization of lignin and other coproducts resulting from the RWH process, -Determine and validate the targeted technical, safety, economic as well as environmental/social sustainability performances to be achieved for a commercial plant. This project aligns with the core innovation strategies of 2 SMEs which are: deconstructing of wood (SEKAB, SWE) and conversion of sugars/hydrolysates into bio-IBN (GBE, FR). These 2 SMEs are already operating a demo plant that they intend to further upgrade within the project. Related Work packages, tasks, milestones and risks are considered in order to achieve these objectives. REWOFUEL project is fully aligned with the call topic.
