Phase-stable indium sulfide achieves an energy conversion efficiency of 14.3% for solar-assisted carbon dioxide reduction to formate
Michael Graetzel, Jing Gao, Jingshan Luo, Xiaoyu Zhang, Jun Li, Qixing Zhang
Tremendous efforts have been made in developing highly selective catalysts for electrochemical CO 2 conversion to formate. However, the rapid deactivation resulting from structural reconstruction and phase transition poses considerable challenges to the sy ...
Cell Press2024Design and assessment of an evaporating water-cooled methanation reactor for a SOE-based power-to-methane system
The transition towards clean renewable energy sources, where wind and solar are prone to variation, requires adequate energy storage. Power-to-methane (PtM) systems can be part of the solution. Specifically, solid-oxide-electrolyser (SOE) based PtM systems ...
EPFL2024In Situ Synthesis of CuxO/N Doped Graphdiyne with Pyridine N Configuration for Ammonia Production via Nitrate Reduction
Sophia Haussener, Roberto Valenza, Jian Li
Electroreduction of nitrate to ammonia provides an interesting pathway for wastewater treatment and valorization. Cu-based catalysts are active for the conversion of NO3− to NO2− but suffer from an inefficient hydrogenation process of NO2−. Herein, CuxO/N- ...
2024Tailoring nanocatalysts and reaction interfaces for water- and CO2-electrolysis
Renewable energy sources offer a promising solution for mitigating sustainability and CO2 emissions-related issues due to their vast energy generation capacity. They enable hydrogen production via water electrolysis, as well as carbon capture and utilizati ...
EPFL2024The thermodynamic and life-cycle assessments of a novel charging station for electric vehicles in dynamic and steady-state conditions
Jan Van Herle, Hossein Pourrahmani, Chengzhang Xu
The current study performs the thermodynamic and life-cycle assessments (LCA) of a novel charging station in two system designs. The goal is to design an efficient charging station for electric vehicles with high efficiencies and low environmental impacts ...
NATURE PORTFOLIO2023Estimating Future Costs and Carbon Footprints of PEMEC and SOEC Manufacturing
The net-zero emission target necessitates a significantly expanded deployment of clean technologies compared to their current utilization. Precisely estimating the future potential of these technologies requires a thorough understanding of their cost and c ...
2023Lab-Scale Investigation of the Integrated Backup/Storage System for Wind Turbines Using Alkaline Electrolyzer
Jan Van Herle, Hossein Pourrahmani
The depletion of fossil fuel sources has encouraged the authorities to use renewable resources such as wind energy to generate electricity. A backup/storage system can improve the performance of wind turbines, due to fluctuations in power demand. The novel ...
MDPI2023Anion Exchange Ionomers Enable Sustained Pure-Water Electrolysis Using Platinum-Group-Metal-Free Electrocatalysts
Xile Hu, Ariana Serban, Fang Song, Nanjun Chen, Yiwei Zheng
Anion exchange membrane water electrolyzer (AEMWE) is a rising technology that offers potential advantages in cost and scalability over proton exchange membrane water electrolyzer (PEMWE) technology. However, AEMWEs that stably operate in pure water still ...
2023The design and development of anion exchange membranes for hydrogen fuel cells
Hydrogen fuel cells are an essential component of hydrogen economy, which have been advocated as a major path towards the decarbonization of the energy sector. Within the two main types of low-temperature hydrogen fuel cells, anion-exchange membrane fuel c ...
EPFL2023Anisotropic In-Plane strain engineering Ni(OH)2 to activate alkaline hydrogen evolution reaction
Realizing a hydrogen economy strongly requires alkaline water electrolysis to achieve large-scale generation of H2, but lacks stable and efficient catalysts. The insufficient active sites in Ni(OH)2 impair the catalytic performance of alkaline HER. Herein, ...
