Hydrogen : A clean energy carrier
Hydrogen is rapidly gaining traction as a clean energy carrier due to its inherent properties .
Unlike fossil fuels , hydrogen combusts cleanly , producing only water vapor as a byproduct . This translates to zero carbon emissions at the point of use , making it a highly attractive option in the fight against climate change . Furthermore , hydrogen boasts a remarkable energy density by weight , surpassing even gasoline . While its volumetric energy density is lower , advancements in storage technologies are continuously mitigating this limitation .
