The Journey of Coal: From Chemical Bond to Electrical Grid
You might think coal is just a dirty rock, but it's actually a tightly packed battery of ancient sunshine. Inside, it's mostly carbon atoms locked to hydrogen.
To get that energy out, we need a spark to break those old bonds apart. This takes a little bit of input energy, tearing the carbon and hydrogen away from each other.
But here is the magic trick. When that free carbon snaps together with oxygen from the air, it forms carbon dioxide. This new double bond is incredibly stable, and locking it into place releases a massive burst of thermal energy.
