On the left, pure hydrogen hissed into a pressurized vein, ready to fuel a fleet of transcontinental trucks. On the right, carbon dioxide—captured directly from the local atmosphere—was being forced into a marriage with water.
Dr. Elena Vance stood before a transparent tank the size of a shipping container. Inside, a forest of jagged, midnight-blue electrodes pulsed with a faint, rhythmic glow. This wasn't the "battery in a lemon" experiment from grade school. This was the front line of the Great Decarbonization. "Ready to breathe?" she whispered. modern electrochemistry
She tapped a command on her tablet. A surge of electrons, harvested from a wind farm three hundred miles offshore, tore through the saltwater inside the tank. In the old days, this would have just made bubbles. But Elena’s electrodes were coated with a "smart" catalyst—a molecular lattice that acted like a microscopic sorting machine.
