“Researchers at Virginia Tech announced Thursday that their latest breakthrough in hydrogen extraction technology could lead to widespread adoption of the substance as a fuel due to its ease of availability in virtually all plant matter, a reservoir previously impossible to tap. The new process uses a cocktail of 13 enzymes to strip plant matter of xylose, a sugar that exists in plant cells. The resulting hydrogen is of an such a ‘high purity’ that researchers said they were able to approach 100 percent extraction, opening up a potential market for a much cheaper source of hydrogen than anything available today.”
