The Hydrogen fuel cell just great but filling could be the issue short term.
The Home fillers HES lV uses natural gas in order to produce the Hydrogen, for the CO2 watchers utilising this system in production of Hydrogen and incorporating it in home heating could reduce these emissions by up to 30%.
But this will take a few years to develop the home system is at least 7 years off.

Fuel cell efficiency
The efficiency of a fuel cell is dependent on the amount of power drawn from it.
Drawing more power means drawing more current, which increases the losses in the
fuel cell. As a general rule, the more power (current) drawn, the lower the
efficiency. Most losses manifest themselves as a voltage drop in the cell, so
the efficiency of a cell is almost proportional to its voltage. For this reason,
it is common to show graphs of voltage versus current (so-called polarization
curves) for fuel cells. A typical cell running at 0.7 V has an efficiency of
about 50%, meaning that 50% of the energy content of the hydrogen is converted
into electrical energy; the remaining 50% will be converted into heat.
(Depending on the fuel cell system design, some fuel might leave the system
unreacted, constituting an additional loss.)

For Australia no good news on this Honda hybrid from a recent Honda press release
"Honda Australia’s Managing Director, Yasuhide Mizuno said while there were
no immediate plans to import the FCX Clarity to Australia it was part of Honda
Australia’s long term vision.
“The lack of infrastructure in Australia is the biggest hurdle at present;
however the Clarity shows that Honda has introduced the future to the world
today."
