The transport sector accounts for 47% of New Zealand’s carbon dioxide emissions, RNZ reports. Battery-driven electric vehicles have been highlighted as the sole pathway to a net-zero transport sector, but a life-cycle approach suggests we should consider more than one option. Electric vehicles, for example, with hydrogen-powered fuel cells, have the edge on battery-driven cars in three important ways: longer range, shorter refuelling time and greater payload. Recent research suggests the cheapest, and environmentally and socially most acceptable approach, is to combine complementary characteristics of these technologies.
