Coal Could Equal Hydrogen
Laramie, Wy – Scientists at the University of Wyoming's hydrogen conference say they hope the state's coal can be used to extract hydrogen for fuel. That puts Wyoming in a good position to benefit from the alternative energy. Researcher Steve Benson says using gasified coal to harvest hydrogen is still the cheapest way.
"Hydrogen from coal is an economically viable approach to getting hydrogen in the short term. We can't get it economically from solar. Wind is still a very high cost.
Unlike wind or solar power, using coal to get hydrogen produces harmful byproducts like mercury, sulfur and carbon dioxide." Benson says technology is developing to purify those toxins from the gas. He says using coal to produce hydrogen is a bridging technology that will lead to cleaner ways to extract hydrogen from renewable energy sources.
