In 2014 a low-temperature {{convert|50|C|F}}, atmospheric-pressure [[enzyme]]-driven process to convert xylose into hydrogen with nearly 100% of the theoretical yield was announced. The process employs 13 enzymes, including a novel [[polyphosphate]][[xylulokinase]] (XK).<ref>{{cite web|url=http://www.greencarcongress.com/2013/04/vt-20130403.html |title=Virginia Tech team develops process for high-yield production of hydrogen from xylose under mild conditions |doi=10.1002/anie.201300766|publisher=Green Car Congress |date=2013-04-03 |accessdate=2014-01-22}}</ref><ref>{{cite doi|10.1002/anie.201300766}}</ref>
 
==Renewable hydrogen==
Currently there are two practical ways of producing hydrogen in a renewable industrial process. One is to use [[power to gas]] where renewable power is used to produce hydrogen from electrolysis and the other is [[landfill gas]] to produce hydrogen in a steam reformer. Hydrogen fuel, when produced by renewable sources of energy like wind or solar power, is a [[Renewable fuels#Hydrogen fuel|renewable fuel]].<ref>{{cite journal |url=http://www.nrel.gov/docs/fy04osti/36178.pdf#page=4 |publisher=[[National Renewable Energy Laboratory]] |journal=Research Review |title=New Horizons for Hydrogen |date=April 2004 |issue=2 |pages=2–9}}</ref>
