Sulfonated sPPFS-b-PBuA diblock and statistical copolymers based on 2,3,4,5,6-pentafluorostyrene PFS butyl acrylate BuA were elaborated for Proton Exchange Membrane Water Electrolyser (PEMWE) purposes. The block (BCP) synthetized by Nitroxide Mediated Polymerization NMP, a controlled radical polymerization technique that yields well-defined molar mass low dispersity material. These diblock-copo...

Abstract “Green” hydrogen produced using electrolysis and zero-carbon electricity may be a path for the EU to reduce its dependence on natural gas imports support green transition. The uses 10 Mt of yearly production, representing potential 120 GW market wind industry. Placing production (electrolysers) near energy source (wind turbines) instead consumer (e.g. fertiliser producers) changes tran...

Seismic events and aftershocks can cause devastating impacts on overground underground energy system infrastructure. This article designs a novel approach to restore functionality in response seismic stresses by using coordinated dynamic reconfiguration operation. First, the impact of infrastructure is evaluated, considering critical components, including electricity lines, substations, gas pip...

Three different power-to-methane process chains with grid injection in two scales (1 MW el and 6 ) were analysed regarding their investment operation cost. The based on biological or catalytic bubbling fluidised bed methanation combination proton exchange membrane solid oxide electrolyser cells. A bottom-up techno-economic analysis showed a cost benefit of around 17–19% lower biomethane product...

Understanding the deactivation mechanisms affecting state-of-the-art, Ir oxide catalysts employed in polymer electrolyte water electrolyser (PEWE-) anodes is of utmost importance to guide catalyst design and improve PEWE-durability. With this motivation, we have tried decouple contributions various degradation overall performance losses observed rotating disk electrode (RDE) tests on three diff...

Hydrogen is currently being promoted because of its advantages as an energy vector, potential to decarbonise the economy, and strategical implications in terms security. from high-temperature electrolysis coupled with concentrated solar power (CSP) especially interesting since it enhances last two aspects could benefit significant technological progress coming years. However, there a lack studi...

A significant contribution to the reduction of carbon emissions will be enabled through transition from a centralised fossil fuel system decentralised, renewable electricity system. However, due intermittent nature energy, storage is required provide suitable response dynamic loads and manage excess generated with utilisation during periods low generation. This paper investigates use stationary...

Solid oxide electrolyser (SOE) technology can become a key player in energy systems, with increasing shares of electricity from fluctuating sources such as wind and solar, contributing to power grid balance storage well providing green fuels for transportation. Most mature SOE configurations are electrolyte supported or fuel electrode supported. Metal cell an interesting concept decreasing cost...

The effect of different alkali metal cations on the oxygen evolution activity and battery capacity nickel electrodes has recently been studied in low concentration hydroxide electrolytes. As high electrolytes are favored applications due to their conductivity, we investigate if cation effects observed translate more industrially relevant conditions for both alkaline water electrolysis iron batt...
