Hydrogen storage technology: a relevant GS3 Science & Technology topic for green energy transition.

Why in news

Scientists at IISER Thiruvananthapuram developed magnesium hydridomethylzincate as a novel compound for the efficient storage and transport of hydrogen and methane.

Background

The study, published in Science Advances on October 7, identifies magnesium hydridomethylzincate as a carrier for hydrogen and methane. The gases are released when the compound is heated to temperatures between 80-110°C, though the material remains moisture-sensitive.
