A Cheaper Way to Produce Hydrogen (IMAGE) DOE/SLAC National Accelerator Laboratory Caption Stanford graduate student McKenzie Hubert watches a catalyst produce bubbles of hydrogen in a small, lab-scale electrolyzer. The catalyst, cobalt phosphide, is much cheaper than the platinum catalyst used today and could reduce the cost of a process for making hydrogen - an important fuel and industrial chemical - on a large scale with clean, renewable energy.
