==== In vehicles ====
In a [[fuel cell vehicle]] the tank-to-wheel efficiency is greater than 45% at low loads<ref name=RSC>Eberle, Ulrich and Rittmar von Helmolt.

Energy & Environmental Science, [[Royal Society of Chemistry]], 14 May 2010, accessed 2 August 2011</ref> and shows average values of about 36% when a driving cycle like the NEDC ([[New European Driving Cycle]]) is used as test procedure.<ref name="status2007">{{Cite journal| title = Fuel Cell Vehicles:Status 2007 | journal=Journal of Power Sources | date = 20 March 2007 | doi = 10.1016/j.jpowsour.2006.12.073 | author = Von Helmolt, R. | volume = 165 | pages = 833–843 | last2 = Eberle | first2 = U| issue = 2| bibcode = 2007JPS...165..833V }}</ref> The comparable NEDC value for a Diesel vehicle is 22%. In 2008 Honda released a demonstration fuel cell electric vehicle (the [[Honda FCX Clarity]]) with fuel stack claiming a 60% tank-to-wheel efficiency.<ref>{{cite web| url=http://automobiles.honda.com/fcx-clarity/fuel-cell-comparison.aspx| title=Honda FCX Clarity – Fuel cell comparison| publisher=Honda| access-date=2009-01-02| archive-date=3 January 2009| archive-url=https://web.archive.org/web/20090103204930/http://automobiles.honda.com/fcx-clarity/fuel-cell-comparison.aspx| url-status=dead}}</ref>

It is also important to take losses due to fuel production, transportation, and storage into account. Fuel cell vehicles running on compressed hydrogen may have a power-plant-to-wheel efficiency of 22% if the hydrogen is stored as high-pressure gas, and 17% if it is stored as [[liquid hydrogen]].<ref>{{cite web|title=Efficiency of Hydrogen PEFC, Diesel-SOFC-Hybrid and Battery Electric Vehicles |date=15 July 2003 |url=http://www.efcf.com/reports/E04.pdf |access-date=2007-05-23 |url-status=dead |archive-url=https://web.archive.org/web/20061021051748/http://www.efcf.com/reports/E04.pdf |archive-date=21 October 2006 }}</ref>
