Editing The Hydrogen Economy (section)

== <span style="color: #FFFFFF;">Understanding</span> ==
The hydrogen economy is understood through '''Storage''' and '''Decarbonization'''.

'''1. The "Chemical" Battery (Storage)''':
Why not just use "Batteries"?
* **Lithium Batteries** are great for "Cars" (see Article 536), but they "Lose Charge" over time and are **"Too Heavy"** for "Long-Distance Trucking" or "Global Shipping."
* **Hydrogen** can be "Stored" in "Massive Underground Salt Caverns" for **"Months."**
* You can "Harvest" "Solar Energy" in the "Summer" and "Burn" the "Hydrogen" in the "Winter."
* It "Solves" the **"Intermittency"** of Renewables.

'''2. The "Hard-to-Abate" Sectors (Decarbonization)''':
"Cleaning" the "Dirty" Industries.
* Some things "Cannot" be "Electrified" easily: **Steelmaking,** **Aviation,** **Shipping,** and **Chemicals.**
* **Steel** currently uses "Coal" (Coke) to "Remove Oxygen" from "Iron Ore."
* **Hydrogen** can "Do the Same Job" and release **"Steam"** instead of "CO2."
* "Hydrogen" is the **"Industrial Detergent"** for the "Carbon Economy."

'''3. The "Fuel Cell" Magic (Conversion)''':
"Electricity without Burning."
* A **Fuel Cell** is like a "Battery that never runs out" as long as it has "Hydrogen."
* It is **"Silent"** and "Efficient."
* In a **Hydrogen Bus**, the only thing "Coming out of the tailpipe" is **"Pure Water."**
* It "Restores" "Air Quality" to "Cities" (see Article 132).

'''The 'Apollo' Fuel Cells'''': The "First" "Successful" application. Fuel cells provided "Electricity and Drinking Water" to the astronauts. It proved that "Hydrogen" was a "Reliable" and "Multi-Functional" energy source for the "Most Extreme" environments.
