Beyond Technological Maturity: Understanding the Institutional Trajectories of Carbon‐Derived Renewable Methane in the European Energy System

EcoEnergy, EarlyView.
We demonstrate that the limitation of bioCO2‐derived methane is systemic rather than technological, and provide a validated framework for traceability, certification, and policy alignment enabling its integration into RFNBO‐compliant value chains and EU energy systems. ABSTRACT Renewable methane derived from biogenic CO2 (bioCO2) occupies a paradoxical

Lattice and Surface Engineering of Transition Metal Oxide Photoanodes for Efficient Photoelectrochemical Water Splitting

EcoEnergy, EarlyView.
This review highlights phase control, facet control, and atomic vacancy engineering as key strategies to enhance charge transport, light harvesting, and surface activity in PEC photoanodes. ABSTRACT Photoelectrochemical (PEC) water splitting is a promising approach for converting solar energy into hydrogen, yet the performance of transition metal oxide

CsI and some new photocathodes [PDF]

Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 1994
A discussion of the possible sources of discrepancies in the measurements of the quantum efficiency of CsI photocathodes is presented. We propose that the major causes for disagreements in QE are due to the QE dependence on the current density extracted from the photocathode, on the electric field, and on the temperature of the photocathode ...
