Honda rolls out new zero-emission car

"The biggest obstacles standing in the way of wider adoption of fuel cell vehicles are cost and the dearth of hydrogen fuel stations. For the Clarity's release in California, Honda said it received 50,000 applications through its website but could only consider those living near stations in Torrance, Santa Monica and Irvine."

"The small number of hydrogen fuel stations is the "single limiting factor" for fuel cell vehicles".

Helen should substitute her 'carbon neutral' rhetoric with something a little more realistic such as building hydrogen re-fueling station in Auckland, Christchurch, and Wellington.
