Hydrogen is the most viable fuel for powering the passenger cars of the future, so said a group of well-placed experts this afternoon. And for once talk like that is being backed up with actions.

It was the message anyone who attended today’s plenary session on the future of hydrogen for passenger cars at World Future Energy Summit in Abu Dhabi would have taken away.

While the debate on the cost, range and technology limitations and infrastructure for electric cars rumbles on, it seems hydrogen fuel-cell technology has been slowly developing in the background and is now on the cusp of deployment. Cars like Mercedes’ B-class F-cell and Honda’s FCX Clarity have shown us this in recent months.

Before we get to the benefits, it’s worth considering the biggest problem of hydrogen: an infrastructure to support its distribution.
