Electrocatalytic conversion of carbon monoxide (CO) is being actively developed as a key component for tandem CO2 electrolysis. Great effort has been devoted to engineering CO reduction electrocatalysts better multicarbon product selectivity. However, less work focused on other performance parameters that are crucial commercializing electrolysis, such liquid concentration and purity. Here, we p...

The accumulation of energy from non-programmable renewable sources is a crucial aspect for the transition. Using surplus electricity sources, power-to-gas plants allow to produce substitute natural gas (SNG) that can be injected in existing infrastructure large-scale and long-term storage, contributing grid decarbonisation. plant layout, method used carbon dioxide capture possible cogeneration ...

The design of a 10 cm2 (3.4 cm by 3.4 cm) and 100 (10 anion exchange membrane (AEM) water electrolyser cell for hydrogen production are described. AEM cells based on zero-gap configuration where the is sandwiched between anode cathode so as to minimise voltage drop electrodes. Nonprecious nickel-based metal alloy oxide catalysts were employed. Various experiments carried out understand effects ...

Urea is often present in waste water but can be used powering fuel cells and as an alternative oxidation substrate to electrolyser. However, insufficient mechanistic understanding the lack of efficient catalysts for urea reaction have hampered development such applications. Here we demonstrate that a nickel ferrocyanide (Ni2Fe(CN)6) catalyst supported on Ni foam drive with higher activity bette...

Direct methanation of biogas enables the storage electrical energy in carbon-neutral (bio-)methane and subsequent injection into national gas distribution grid. The intermittent availability renewable electricity, as well varying nature production by e.g. anaerobic digestion, necessitate enhanced operational flexibility such a Power-to-Gas process intermediate buffer storage. This work provides...

This study investigated the impact of dual-fuel operation using ethanol-blended diesel fuel enriched with hydroxy gas on CRDI engine performance, combustion, and emission characteristics. Neat was used to run engine, along a 20% volume fraction an ethanol-diesel mixture that had been enhanced three distinct streams gas, namely 1, 1.5, 2 LPM. Hydroxy generated by electrolysis technique plate-typ...

The realization of a carbon-neutral civilization, which has been set as goal for the coming decades, goes directly hand-in-hand with need an energy system based on renewable energies (REs). Due to strong weather-related, daily, and seasonal fluctuations in supply REs, suitable storage devices must be included such systems. For this purpose, model featuring hybrid consisting hydrogen unit (for l...

Two electrolysis technologies fed with renewable energy sources are promising for the production of CO2-free hydrogen and enabling transition to a society: Alkaline Electrolyte (AE) Polymer Membrane (PEM). However, limited information exists on potential environmental impacts these sustainable innovations when operating large-scale. To fill this gap, performance AE PEM systems is compared, usin...

Abstract We present the results of a life-cycle assessment (LCA) for manufacturing and end-of-life (EoL) phases following fuel-cell hydrogen (FCH) technologies: alkaline water electrolyser (AWE), polymer-electrolyte-membrane (PEMWE), high-temperature (HT) low-temperature (LT) fuel cells (PEMFCs), together with balance-of-plant components. New inventories (LCIs), i.e., material inputs AWE, PEMWE...
