The production fuel cell is a bold step because there is only a minimal hydrogen infrastructure in Europe.

I also look forward to fuel cell micro CHP, although there are still major issues with creating a hydrogen infrastructure.

The planned highway is part of the hydrogen infrastructure, there are several hydrogen re-fueling stations planned along the route.

And despite the publicity given to fuel-cell cars, practical versions remain a dream, given the challenges of creating a hydrogen infrastructure.

Hydrogen pipeline transport is a transportation of hydrogen through a pipe as part of the hydrogen infrastructure.

A liquid hydrogen infrastructure would be prohibitively expensive.

Still, fuel-cell cars face huge hurdles, especially the lack of a cost-efficient hydrogen infrastructure.

The hydrogen infrastructure is embryonic: There are about 700 miles of hydrogen pipelines in the country, compared with a million miles for natural gas.

A hydrogen infrastructure will cost considerably more to construct and maintain (some estimates top 500 billion dollars).

Fuel cell vehicles and the hydrogen infrastructure to fuel them are in an early stage of development.
