Where is the evidence and research?

Continuation of the article:
The Japanese carmaker believes hydrogen fuel-cell vehicles offer the best long-term alternative to fossil fuels, and the US arm of the company is showing a refuelling breakthrough that it says points to a home version down the road.

Among the world's carmakers, Honda is widely seen as the hydrogen leader, tempted by the idea of a car that uses no petrol and emits only water vapour. Others like General Motors put more effort into battery-powered electric vehicles such as the upcoming Chevrolet Volt.

One of the big barriers to hydrogen car deployment is the lack of refuelling infrastructure, leading Honda to bet that the future lies in combining a public station network with a more modest home option.

Analysis:
After the first four paragraphs, there isn’t a quote in sight. These paragraphs do set the stage for what is happening in the field of renewable resource-based cars, but there is a lack of source evidence.
It seems like the journalist here has not done enough research on renewable resource-based cars and their affect on global climate change. The lack of refueling infrastructure is truly a con. The car only emits water vapor, as stated above, but water vapor is also a greenhouse gas. There is no mention of that fact within that paragraph where it would be important. It is unclear whether the author was unaware of this fact, omitted it for belief of common knowledge in readers, or if this drawback was not deemed significant enough.
