Blue Energy for Green Hydrogen Fuel: A Self‐Powered Electrochemical Conversion System Driven by Triboelectric Nanogenerators

Utilizing hydrogen energy produced by water electrolysis is conducive to carbon neutrality from a technological point of view. However, this perspective is restrained by the high electricity cost in commercial development. Powering electrochemical reactions by renewable electricity converted from distributed mechanical energy can lead to commercial electric energy saving and cost reduction. In this work, a self‐powered electrochemical system...
