Role of Microwaves in Green Hydrogen Production and Storage

This concise review discusses the generation of hydrogen using microwaves and explores the necessity for storage, advantages, and challenges of hydrogen energy. It provides concrete examples to demonstrate how microwaves can address the obstacles to a hydrogen-based economy. The text delves into the challenges of hydrogen storage and suggests that a microwave microscopic high-temperature field can mitigate the challenges of liquid organic hydrides hydrogen carriers (LOH2Cs). It also presents the principles underlying the microwave microscopic high-temperature field and showcases examples. The use of LOH2Cs is shown to enable the generation of more than 85% hydrogen from seawater, model wastewaters containing polymers, model wastewaters containing pesticides, and the decomposition of organic matter. Furthermore, we discuss a case study of using microwave pyrolysis to decompose waste and sludge to recover hydrogen. By highlighting the potential of microwaves in driving the transition to a Hydrogen Economy, this brief review offers insights into achieving this goal.
