Perspective on the hydrogen economy as a pathway to reach net-zero CO2 emissions in Europe

Mijndert van der Spek et al.

Summary: The role of hydrogen in the energy transition has evolved over the years, and the current focus is on its versatility in aiding the transition to CO2 neutrality. However, strong political support and robust infrastructure design are necessary for the realization of the hydrogen economy. Multiple barriers need to be addressed, including technology development, infrastructure co-creation, policy, market design, and business model development. This article provides a comprehensive understanding of the elements in the hydrogen economy, its current state, and the gaps that need to be filled.

Impact of Bubbles on Electrochemically Active Surface Area of Microtextured Gas-Evolving Electrodes

Jack R. Lake et al.

Summary: This study investigates how electrochemical bubbles dynamically alter the electrochemically active surface area during bubble evolution. The researchers discover that the most densely microtextured electrodes have the lowest performance due to the inactivation induced by bubbles growing within the denser microtexture. Furthermore, the study shows that the area beneath adhered bubbles is electrochemically active, contrary to currently held assumptions.

Bubble identification from images with machine learning methods

H. Hessenkemper et al.

Summary: This paper presents an automated and reliable processing method for bubbly flow images. It utilizes Convolutional Neural Networks (CNNs) to identify individual bubbles and tests various methods to handle different image conditions and bubble characteristics. Synthetic images are used to validate the capabilities and limitations of the approach, and the generated data, code, and trained models are provided for research purposes.

On the growth regimes of hydrogen bubbles at microelectrodes

Aleksandr Bashkatov et al.

Summary: This study investigates the growth of single hydrogen bubbles at micro-electrodes in an acidic electrolyte. New bubble growth regimes are identified and key features such as bubble radius growth law, dynamics of microbubble carpet, onset time of oscillations, and oscillation frequencies are characterized. The system's response to jumps in cathodic potential is also studied, leading to a hypothesis on the mechanisms underlying the microbubble carpet and oscillations.

Design of membraneless gas-evolving flow-through porous electrodes

H. Rajaei et al.

Summary: Flow-through electrolyzers are commonly used in industrial applications to avoid concentration gradients and enable membrane-less operation. A simple multiphase flow-through electrode model is proposed in this study, along with an analytical expression for the minimum velocity required for effective gas separation. Design parameters derived from the relation show significant energy savings can be achieved using flow compared to a physical separator.

A membrane-free flow electrolyzer operating at high current density using earth-abundant catalysts for water splitting

Xiaoyu Yan et al.

Summary: Electrochemical water splitting is a sustainable method for generating hydrogen, but traditional and emerging electrolyzers face efficiency and cost challenges. The membrane-free flow electrolyzer designed by the authors allows for efficient water splitting at high current densities. By combining the advantages of different electrolyzer concepts, the study paves the way for sustainable hydrogen generation.
