This work discusses the perspectives of New Zealand to progress toward net zero, within a scenario of stable total energy supply. The renewable energy contribution is expected to dramatically grow from 35% in 2021, by increasing the non-dispatchable power generation by solar photovoltaic and wind. Phased with this growth of non-dispatchable power generation, energy storage primarily by hydrogen must also increase, to make dispatchable part of this non-dispatchable supply from wind and solar, and to produce green hydrogen to cover the non-electric component of the total energy supply. This is partially acknowledged by the local intelligentsia, which assumes the total energy supply may reduce in time, thanks to the electrification of almost every component of the total primary energy and living-with-less, and transformation to pumped hydro of the Lake Onslow hydroelectric plant could suffice to accommodate an acceptable growth of wind energy. Opposite, we believe a much larger growth will be necessary for both wind and solar, and the larger will be the share of wind and solar contribution to the total energy supply, the larger will have to be the share of hydrogen, with living-with-less arguments difficult to couple to a growing country in a growing world.
