Ranking the Future: Carbon Capture Pathways That Actually Work

In this AI-generated episode of The Zero Emission Zone, we explore a cutting-edge study that evaluates the most promising carbon capture and utilization (CCU) processes using a new Sustainable Feasibility Index (SFI). The researchers rigorously model and assess eleven CCU pathways—like acetic acid, formic acid, and calcium formate—based on environmental, economic, and market factors. Tune in to find out which technologies are truly viable for a net-zero future. https://doi.org/10.1016/j.rser.2025.115331 [https://doi.org/10.1016/j.rser.2025.115331]

Cracking the Code: Reaction Pathways in CO₂ Electrolysis

In this AI-generated episode of The Zero Emission Zone, we break down a 2025 perspective by Seger et al. on the dominant reaction mechanisms in CO₂ electrolysis. From C1 to elusive C3 products, this work synthesizes computational and experimental data into a coherent map of how CO₂ transforms into fuels and chemicals on copper catalysts. Listen in as we explore the formal rules that may unlock cleaner fuel production through electrified chemistry. https://doi.org/10.1021/acsenergylett.4c03599 [https://doi.org/10.1021/acsenergylett.4c03599]

Platinum Maps and Proton Paths: Diagnosing Fuel Cell Aging

In this episode of The Zero Emission Zone, we explore how platinum distribution within PEM fuel cell cathodes impacts the measurement of proton transport resistance. Drawing from new research by Mehrazi et al. at Bosch, we unpack why measuring at the right potential is crucial—and how impedance spectroscopy can double as a diagnostic tool for catalyst aging.
