Carbon valorisation in energy-efficient green fuels
The CONVERGE project will validate an innovative value chain for the production of green biodiesel. The innovative configuration will reduce the total number of unit operations needed to achieve the conversion of secondary biomass and waste streams into green biodiesel, while simultaneously producing additional intermediate green refinery products.  The CONVERGE project will demonstrate 5 unit operations in 3 grouped processing steps (pre-processing, valorization & enhanced methanol), taking these new combinations from the discovery stage (TRL3) to development stage (TRL5).  The combination of these technologies will increase the biodiesel production from secondary biomass by 12% together with biodiesel production will be reduced by up to 2100 M€ across Europe.  In this project, risks are mitigated from the very start; each unit can be implemented as a stand-alone function within a modified state-of-the-art technology chain and thus provide immediate performance and energy efficiency improvements. Moreover, the units when used together have synergies that allow even more efficiency gains.  The new units to be taken from discovery to development are: CCT: Catalytic cracking of tars from a gasifier to below green C8, integrated with  BITS: Recovery of refinery products including aromatics for green C6-C8 fraction (BTX). Then, SER: Sorption-Enhanced Reforming is adopted for H2 and CO2 separation, integrated with  EHC: Highly efficient electrochemical compression of green H2 with by-product fuel EMM: Enhanced Methanol Membrane synthesis to ensure green biodiesel production. The technology will be validated  for more than 2000 cumulated hours. The CONVERGE consortium covers the whole value chain from secondary biomass supply to biodiesel production, demonstrating the new unit operations on site within an ambitious 42 months period.
