Following the Charge

How our activated carbon, made from petroleum coke, is finished into an electrode carbon for supercapacitors (Part 1), and how it and a carbon left over from making hydrogen become graphite for lithium-ion batteries (Part 2). Press Start here for a short introduction, then open a chapter from the map. Each chapter can be watched with narration or stepped through at your own pace, and brings you back to the map when it ends.

Illustrated bird's-eye view of a northern lakeside landscape. On the left, a carbon plant with a long kiln and two silos beside a small finishing building, and above it a hydrogen plant with two tall towers. Two roads run through spruce and birch forest: one past a small white laboratory, the other past a tall white furnace building fed by power lines. Both reach a lakeside town with an electric bus at a charging stop, houses with an electric car and a home battery, a harbour crane, a railway, a row of grid battery containers and wind turbines on a granite ridge.
