A team of Stanford chemists believe that liquid organic hydrogen carriers can serve as batteries for long-term renewable energy storage.; The storage of energy could help smooth the electrical ...
We still need to transport that hydrogen somehow to gas stations or hydrogen stations, and you still need to store it. And that''s not cheap. ... And, like gasoline, hydrogen packs way more energy per pound than a battery. That means it''s really useful in something like heavy duty trucking, which needs to carry a lot of weight a long distance ...
Hydrogen fuel cells have an energy to weight ratio ten times greater than lithium-ion batteries. This means that hydrogen powered vehicles have the potential to offer much greater range, while being lighter. In addition, whereas lithium batteries have a limited lifespan and need to be replaced, fuel cells do not degrade in the same way.

Hydrogen vehicles are a type of electric car that use fuel cells to power the motor instead of relying primarily on a lithium-ion battery pack; they don''t burn fuel like gasoline cars.
To realize the environmental benefits of hydrogen, however, we must consider the full fuel cycle (also called "well-to-wheels")—from energy source to hydrogen production to end-use. …
While the hydrogen fuel combustion itself produces no carbon emissions, the process to make hydrogen does. Hydrogen produced from coal or gas in this way is called ''black and grey hydrogen'' respectively, while ''blue hydrogen'' refers to a process in which the carbon dioxide is captured from coal gasification and stored beneath the earth ...
