—Method converts petroleum to hydrogen and produces little CO2 “Advance relies on using microwaves to directly heat iron catalyst” Petroleum is a relatively inexpensive, abundant, and convenient source of energy. One of the biggest drawbacks to using it as fuel is that doing so generates copious amounts of carbon dioxide, a greenhouse gas. Researchers in the U.K. and Saudi Arabia have taken a step toward mitigating that problem by demonstrating a CO2-free method for converting petroleum samples to high-purity hydrogen, a clean-burning fuel, and solid carbon, which can be stored underground safely or used commercially. Currently, most hydrogen comes from steam reforming methane, an energy-intensive process that produces a lot of CO2.
