Berlin Airports, NH hotel chain join Opel HydroGen4 car trial

摘要

General Motors' German subsidiary Opel has delivered a HydroGen4 fuel cell car each to the Berlin Airports operator and to the NH-Hotel Berlin Friedrichstrasse. The vehicles, which will be operated as part of the Clean Energy Partnership, represent a further expansion of GM/Opel's ongoing market trial with fuel cell vehicles, which has been under way since late 2008.
