The Benning Road station offers hydrogen fuel at an existing gasoline station

On Nov. 10, 2004, Shell Hydrogen opened the first hydrogen dispenser at a retail gasoline station to service a fleet of six fuel cell vehicles from the General Motors Corp. Located in northeast Washington, D.C, the station is part of a collaboration between Shell and GM to demonstrate hydrogen fuel cell vehicles and refueling infrastructure technology. The companies also are working together on the U.S. Department of Energy's Infrastructure Demonstration and Validation Project to help demonstrate and gather data on hydrogen fuel cell vehicles so that they can become an everyday reality. Shell will offer both compressed gaseous and liquid hydrogen fuels at the Benning Road station.

Shell has developed a step-by-step approach to the development of the hydrogen mass market. Its plans include:

The Benning Road station meets Step 3 of this approach.

Station Facts


3355 Benning Road, NE
Washington, DC

Fuels Available:

This station offers:

Hydrogen Delivery:

Liquid hydrogen is delivered to the station by a tanker truck.

Liquid Hydrogen Storage:

The liquid hydrogen is stored below-grade in 1,500-gallon (400-kg) double-walled, insulated, stainless-steel vessels at -420°F.


A vaporizer vaporizes the liquid hydrogen by raising its temperature from -420°F to ambient temperature.


A three-stage compressor compresses the vaporized gas to 5,500 psig. A one-stage compressor compresses it to 11,000 psig.

Gaseous Hydrogen Storage:

Gaseous hydrogen from the compressor is stored at 5,500 psig in 24 ASME cylinders (above grade) and at 10,000 psig in three ASME cylinders (above grade).


The station offers one liquid hydrogen dispenser and one gaseous hydrogen dispenser with dual hoses for dispensing at 5,000 psig and 10,000 psig (20 kg per day).

Safety Features

The station's safety features include:


Hydrogen storage


Station Permitting Process

The Benning Road station underwent and extensive review and approval process by the Office of the Fire Marshall in Washington, D.C. See the Shell Hydrogen Installation Overview, prepared by the Office of the Fire Marshall, for more information.
