Bio-Sourced Materials group

Tannin-based and carbon-based materials and metamaterials for advanced applications

The team develops new porous and metamaterials for advanced and strategic applications for energy transition:

• adsorption and separation of gases: H2, CO2 and CH4
• insulators and superinsulators
• electrodes for electrochemical energy storage and conversion
• heat exchangers for the food industry
• materials for hosting phase-change fluids
• metamaterials for microwave and very high frequency applications
• catalysts for biorefinery
• materials for the production of fresh water by solar evaporation

The materials are mainly derived from bioresources, following an approach inspired by green chemistry. After essential characterization and optimization steps, they are integrated into real devices and the modelling of their structure and properties allows, after feedback on the synthesis, to improve their performance.

Nanoporous carbons for hydrogen storage and compression

The team developed a proof of concept for a non-mechanical hydrogen compressor in collaboration with the LEMTA http://lemta.univ-lorraine.fr. When the tank is filled with hydrogen at 80 bar and 77K, its heating up to 315 K allows hydrogen flow rates of 30 NL/h at 700 bar to be achieved. The studied system is hybrid since it is made up of:

• a first stage of electrochemical compression, which compresses the hydrogen from 1 bar up to 40-80 bar
   
• a second stage of compression by adsorption-desorption which completes the compression up to 700 bar. The modified Dubinin-Astakhov model (MDA) is used to describe the adsorption of hydrogen on activated carbons depending on temperature and pressure conditions. The modeling results were validated by comparison with experimental data obtained from a 0.5 L prototype, designed and built for this work, and containing 0.135 kg of MSC-30 activated carbon (Kansai, Japan).

Currently, the team is working on the correlation between adsorbent textural parameters and MDA model variables as well as on the synthesis of different porous materials with high hydrogen adsorption capacity. Gas adsorption models are being developed in parallel to better characterise and optimise these nanoporous solids.

Mesostructured carbon materials for electrochemical energy and separation

Mesostructuration of carbons is carried out by green chemistry, using a new environmentally friendly method based on water-assisted mechanosynthesis. Using only natural bark extracts, water and a surfactant, it allows ordered (with hexagonal symmetry) or disordered (wormlike pores) mesoporous carbons to be prepared in just one hour before pyrolysis. These solids are highly hydrophobic and have excellent application properties in the fields of energy and environmental, notably as supercapacitor electrodes, for CO2 retention from wet gaseous effluents, and for the separation of branched / linear hydrocarbons. Their different structures, depending on the synthesis conditions, having the same single mesopore size, are also tested for the calibration of reconstruction algorithms from electron tomography images and for modelling the properties of these nanoporous structures.

Development of platinum-free cathodes for fuel cells

The first objective is to develop a platinum-free high-performance catalyst for the oxygen reduction reaction (ORR) based on porous carbonaceous materials doped with nitrogen and boron. The second objective is to optimize the formulation of platinum-free electrode inks in order to achieve reproducible Membrane Electrode Assemblies (MEAs), and then test them for electrochemical energy conversion in a Proton Exchange Membrane Fuel Cell (PEMFC). A spray-coating bench is used to deposit the electrode layers.

The team combines its expertise in carbonaceous material preparation and small-scale electrochemical testing with that of LEMTA http://lemta.univ-lorraine.fr/ in characterizing and testing MEA in instrumented fuel cells. This makes it possible to envisage the rapid development of alternatives to platinum-based electrodes, recognised as a major stake in reducing the cost of PEMFC technology.

Affordable, high-performance "green" electrodes for Redox Flow batteries

The objective is to design, develop and validate a state-of-the-art Redox Flow battery, i.e., another electrochemical energy conversion system than a fuel cell, based on a new low-cost, water-soluble organic electrolyte, compatible with an optimised low-resistance membrane and fast kinetic electrodes for high energy density and long life. Battery engineering is focused on:

• performance optimisation through an advanced control strategy, reaching a LCOS (levelized cost of storage) < 0.10 € / kWh / cycle (end of project) and 0.05 € / kWh / cycle (by 2030)
   
• recycling, in order to minimise the environmental cost of battery installations. The prototype is tested and validated in the Siemens Gamesa https://www.siemensgamesa.com/en-int pilot plant in Spain. The team is working on the optimization of the fibrous carbon electrode
