Sugar to Hydrogen: Meeting the World’s Clean Energy Needsoilprice

Hydrogen is one of the most efficient fuels in the world. It has a far higher energy density than gasoline, and is three times as energy efficient, making it the fuel of choice for NASA to power its space shuttles. It is also incredibly clean, producing only H2O as waste.

The problem is that hydrogen is very difficult to produce on a large scale, and this prevents it from making a significant contribution to the global energy mix. In fact cheapest methods currently available for producing hydrogen involve extracting it from fossil fuels, such as natural gas, which creates carbon emissions, and negates any environmental advantages.

Scientists are trying to develop new methods for creating large amounts of hydrogen for low cost, but Percival Zhang, a professor of bioengineering at Virginia Tech Institute, has stated that the scientists slow progress is in part due to their lack of imagination.
