Hydrogen Sulphide Gas, For Industrial, Grade Standard: Technical Grade

Grey Hydrogen: The least sustainable method is conventional steam methane reforming without carbon capture, known as "grey hydrogen." It generates direct carbon emissions and contributes to climate change.

Hydrogen Storage: Hydrogen has low volumetric energy density, which means it requires specialized infrastructure and technologies for efficient storage and transportation. Methods like compressed hydrogen, liquid hydrogen, and solid-state hydrogen storage are being explored.
