“…The hCA II enzyme, immobilized in the first FBMR, catalyzes the hydration of CO 2 to HCO 3 – , and the thermostable HDCR, immobilized in the second FBMR, catalyzes the anaerobic reduction of CO 2 (replenished by rapid dehydration of HCO 3 – generated in the first FBMR) using golden hydrogen generated by a solar panel that converts sunlight and H 2 O vapor from the air directly into H 2 via surface chemical reactions. This complex integrated enzymatic process, which can be installed on long-range shipping (heavy-duty and marine) vehicles – and in residential, commercial, and public services buildings, overcomes many of the processing limitations of CO 2 reduction and ensures: (i) efficient CO 2 removal (FBMR 1) and enhancement of HDCR’s ability to convert CO 2 to formate (FBMR 2), (ii) efficient conversion of golden H 2 into a high volumetric capacity H 2 energy carrier (FA/formate), and (iii) recirculation of the liquid (with buffer) into new cycles of CO 2 reduction (or CO 2 hydration/reduction) and decreasing formate oxidation. Since the thermostable HDCR enzyme from T.…”

Enzyme-mediated direct CO 2 hydrogenation with upstream enzyme-mediated direct air capture (DAC) in interconnected multiphase fixed-bed microreactors (FBMRs) has been envisioned for the first time for the bioconversion of atmospheric CO 2 . Both processes are catalyzed by the thermostable hydrogen-dependent CO 2 reductase (HDCR) enzyme from the thermophilic acetogenic bacterium Thermoanaerobacter kivui and the human carbonic anhydrase II (hCA II) enzyme immobilized on the surface of solid particles, respectively. The performance of the integrated enzymatic processes was evaluated using 3D models linking Euler−Euler equations of multiphase flow and mass transport equations in liquid and gas phases and diffusion/enzymatic reaction models within hCA II and HDCR enzyme layers. When coupled to an enzymatic DAC FBMR that extracts on-road CO 2 under traffic congestion or CO 2 from the atmosphere, the direct CO 2 hydrogenation FBMR charged with the same enzyme loading and operating at 70 °C can reduce more CO 2 than the DAC FBMR can remove due to the enhanced interphase mass transfer. The coupled multiphase FBMRs with immobilized hCA II/HDCR enzymes can also operate with higher CO 2 concentrations (CO 2 emissions from residential, commercial, and public services buildings), but the enzyme-mediated hydrogenation process (with large HDCR enzyme loadings) is controlled by mass transfer and reverse formate oxidation. FBMRs, which can potentially be installed on heavy-duty and marine vehicles, must be designed and operated under conditions that ensure that the benefits of high CO 2 capture and reduction rates outweigh the cost of energy requirements. Formate must be removed from the reaction system to ensure liquid recirculation and no formate inhibition of the CO 2 reduction.

“…Some authors suggest that amine scrubbing, adsorption and membranes could be adapted to operate on mobile sources. 7,8 So far, the research about CCS systems in mobile sources has been focused on absorption and adsorption. Engine-driven ships offer the most favourable scenario for an absorption installation because the internal combustion engine (ICE) operates almost at the same load condition in a journey, which is quite like the operating conditions of a power plant.…”

CO2 capture by amine scrubbing is a widely developed technology in its most advanced stage of evolution. However, it has never been used to capture CO2 from mobile sources. The present study performs a thermo-economic analysis of an amine scrubbing CO2 capture storage (CCS) system, which takes for the amine regeneration process the waste heat from the exhaust gases of a turbocharged natural gas internal combustion engine (mobile source). The selected engine for the study is an M936G, widely used in freight and passenger transport. A primary and a tertiary amine were chosen for the simulations. In order to reduce volume and increase autonomy, captured CO2 is stored as a liquid; therefore, a specific installation is planned. The system is hybridised with an Organic Rankine Cycle (ORC) to reduce the energy penalty on the CCS system. Results show that a CCS system operating with Monoethanolamine (MEA) at 30 wt% achieved a maximum CO2 capture rate of 66%, with a penalty over the power engine of only 10%. On the other hand, the economic analysis showed that the CCS system with MEA and without ORC is 31.8% cheaper than a hydrogen fuel cells bus and 26% cheaper than a battery-electric bus.

Increasing densities of reaction sites for gaseous reactants in solid oxide electrochemical reactors (SOERs), is a key strategy for achieving enhanced performance in either fuel cell or electrolysis modes. Fabrication of 3D structured components in SOERs can enhance those densities of reaction sites, which is achieved by 3D inkjet printing with high reproducibility, having developed inks with appropriate properties. First, the effects of pillar geometries on SOER performances are predicted through numerical simulations, enabling subsequent 3D printing to focus on the more effective geometries. Herein, the study reports the results of experimental validation of those predictions by evaluating the electrochemical performances of cells with various heights of 3D inkjet‐printed Ni(O)‐ yttria stabilized zirconia (YSZ) pillars and YSZ pillars. Those measurements prove that increasing pillar heights generally increases SOER peak power densities in fuel cell mode and increased current densities at the thermoneutral potential (1.285 V) in steam electrolysis mode, as predicted by simulations. With increasing pillar heights, more limitations in performance enhancement are found with YSZ electrolyte pillars than with Ni‐YSZ pillars, again as predicted by simulations. The subsequent microstructural analysis of Ni‐YSZ pillars proves the suitability of the Ni(O)‐YSZ composite particle ink formulation and the reliability of 3D printing.
