Following the Hydrogen

How the carbon left over when hydrogen is made from natural gas is cleaned and opened up into a support for fuel-cell platinum, and why it held up far better in our lab tests. 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 natural gas pipeline runs into a light-grey hydrogen plant with two tall reactor towers, white storage tanks and a shed filling white bulk bags with black powder, and beside it a small white finishing building; two roads leave the plant, one carrying a truck of gas cylinders and one passing a small white laboratory, and they meet in a lakeside town with a hydrogen fuelling station where a bus fills up, a warehouse with forklifts, a truck on the highway and a phone tower with a power cabinet.
