Hydrogen overhyped

There is much hype about hydrogen as a future energy carrier for New Zealand. The Government's consultation document "A vision for hydrogen in New Zealand" repeats a number of myths about the merits of "Green Hydrogen". Hydrogen is not green; literally or metaphorically.

Converting electricity into hydrogen for use in a fuel cell vehicle would use three times the electricity needed to charge an equivalent battery electric vehicle. NZ's electricity system includes natural gas generation for peak-load operability. Using the hydrogen route to get electricity into the transport sector would increase, not decrease, NZ's carbon footprint.
