Work Package 2: Towards innovative CO2 transformation strategies combining high performance and low environmental impact


  • Develop catalytic systems based on earth-abundant, cheap and non-toxic metals, able to transform CO2 into C1 and beyond C1 products of interest, selective, efficient, and robust (inputs for work package 3) that can be adapted in devices with minimal environmental impact.
  • Develop industrial models based on the state-of-the-art catalytic systems developed at Grenoble (work package 2) to carry out prospective life cycle assessment (LCA) for an evaluation of their environmental impacts (inputs for work package 1).
  • Establish a roadmap for higher performance and lower environmental impact of Carbon and Capture Utilization (CCU) technologies.

Task 2.1. Bio-inspired systems

One strategy will be to develop innovant electro- or/and photo-catalytic systems to activate CO2 and transform it into selective products of interest based on a bio-inspired approach, i.e., on synthetic models, metalloenzymes, or hybrid assemblies. In all these systems, CO2 is activated and transformed at a metallic center composed of non-noble and non-toxic metals, and their performance in terms of efficiency, selectivity, and robustness will be assessed under homogeneous or/and heterogeneous catalytic conditions and mild temperature and pressure (inputs to task 2.3). To go beyond the production of C1 products, cascade chemical processes will also be implemented.

Task 2.2. Performance optimization

Optimization of the performance. To enhance the efficiency, selectivity, and stability of the catalytic systems, the full understanding of the catalytic mechanism and degradation process(es) will be investigated to design their next generation (inputs to Task 2.1) rationally. To do this, we will use several complementary approaches: (i) in operando investigation based on different spectroscopic or spectrometric techniques, (ii) trapping and characterization of short-life species to identify intermediate species, and (iii) quantum chemistry based on different methodologies including dynamic ones, to predict full mechanisms.

Task 2.3 Life Cycle Engineering (LCA)

To perform a thorough analysis of the environmental impacts of new technological approaches, the standardized LCA methodology is the most advanced tool since it is based on a global and multi-criteria evaluation. However, to have a concrete impact, LCA must be carried out as early as possible to have a real impact on development decisions and lead to a system that best meets regulations and political and social expectations. In this work package, we will target our latest breakthroughs in CCU technologies  to provide data for LCA, so that the developed processes can be upscaled, assessed, and optimized (inputs to work package 1 and task 2.1) based on this analysis and industrial engineering methods.
