Stretchable Energy Storage with Eutectic Gallium Indium Alloy

open access: yesAdvanced Energy Materials, Volume 15, Issue 11, March 18, 2025.
A highly stretchable liquid metal‐based electrode is developed via a one‐step process, retaining conductivity and capacitance after mechanical deformation up to 900% strain. The stretchable all‐solid‐state device provides a areal energy density of 43 µWh cm⁻2 after 150% strain.

Economic Viability of Photovoltaic Systems Providing Frequency Containment Reserve

open access: yesAdvanced Energy and Sustainability Research, EarlyView.
This article investigates the feasibility of photovoltaic (PV) systems providing frequency containment reserve (FCR) in the Netherlands. The economic analysis demonstrates that a PV plant can profitably participate in FCR without battery storage by maintaining an active power reserve.
