Once lauded as the future of clean transportation and energy storage in a variety of other applications, hydrogen - based fuel cell systems have a great many barriers to adoption, one of which is lack of hydrogen infrastructure, and the other is the need to develop hydrogen production sources that aren't fossil fuel - based or that require more energy to produce than can be released in the fuel cell.

«I think we need to think hard about making the automobile dramatically simpler with hydrogen and fuel cells,» Burns told Reuters, noting that a fuel - cell propulsion system had one - tenth as many moving parts as an internal combustion engine.

So not only would fuel cell development and technology for storing hydrogen on vehicles need to be further developed, but the automobile industry's development and production of fuel cells also would need to be coordinated with the energy industry's deployment of reformers and the fuel for them.

The hydrogen could then be reused to generate electricity when needed, injected into the heating system or used as low - emission fuel for hydrogen fuel - cell cars.

The fuel cell needs to have a converter built into the car that can convert gas to hydrogen from gas or water, then it is used in the fuel cell to create the energy to power the car.

Dr Frank agrees, noting that the hybridisation would mean cars would need less hydrogen on board, and smaller (and thus cheaper) fuel cells.

When power is needed, the hydrogen is cleanly and efficiently converted back into power using the same solid oxide system in fuel cell power generation mode.

As Koval points out, even though use of hydrogen in fuel cells is growing, the biggest need is for liquid fuel to run cars, trucks, trains and planes.

-- Daniel Nocera But even that price, which does not include the cost of the fuel cell that would be needed to convert hydrogen back to electricity, is not low enough to displace existing energy infrastructure, Nocera says.

That hydrogen could then be stored and used later to generate electricity (via fuel cell or combustion turbine) when the power is most needed, thereby smoothing out the variability of wind.
