Water Electrolysis Facing the Gigawatt Challenge—Comprehensive De‐Risking of Proton Exchange Membrane and Anion Exchange Membrane Electrolyser Technology

open access: yesElectrochemical Science Advances, EarlyView.
ABSTRACT Green Hydrogen (H2) is generally considered to play a key role in enabling sustainable energy storage, as well as a renewable feedstock to various industrial sectors. Accordingly, the production of H2 by water electrolysis at an industrial scale is a key prerequisite for a transformation of our energy system. With respect to water electrolysis,

Minimizing Carbon Capture Costs in Power Plants: A Novel Dimensional Analysis Framework for Techno‐Economic Evaluation of Oxyfuel Combustion, Pre‐combustion, and Post‐combustion Capture Systems

open access: yesEnergy Science &Engineering, EarlyView.
Power generation plants contribute approximately 40% of global CO2 emissions, necessitating the development of carbon capture, utilization, and storage (CCUS) technologies. This study evaluates the technical and economic viability of pre‐combustion, post‐combustion, and oxy‐fuel combustion CO2 capture methods integrated with natural gas power plants ...

Techno‐Economic Comparison of Battery–Flywheel With Battery–Hydrogen Storage System in the Vicinity of Off‐Grid HRES for Four Climates: MCDM Method

open access: yesEnergy Science &Engineering, EarlyView.
ABSTRACT Ensuring sustainable power and heating in remote rural areas presents a considerable challenge. Renewable hybrid systems are typically recommended for this purpose; however, maintaining stability necessitates either a connection to the grid requiring electricity purchases from power plants, which are significant sources of pollution, or the ...
