The research conducted in New Zealand focuses on utilizing a 'clean hydrogen ladder' to quantify and prioritize various uses of green hydrogen. The country's potential demand for green hydrogen stands at approximately 2.8 Mt/y if all technically feasible applications transition to hydrogen, with priority areas being fertiliser, methanol, shipping, jet fuel, steel production, and grid storage. The article highlights the challenges and opportunities associated with long-term hydrogen storage, especially for moving solar energy across seasons. Decarbonizing steel production using hydrogen shows promise, with projects demonstrating the feasibility of hydrogen-based direct reduced iron processes. Exporting hydrogen from New Zealand presents challenges due to the gas's properties, with options like cryogenic liquefaction and ammonia conversion being explored. Cost-efficiency remains a crucial factor, with research focusing on developing low-cost electrolysers and exploring alternatives like 'gold' and 'orange' hydrogen. Despite challenges, the article maintains a positive sentiment towards the potential of hydrogen as a key decarbonisation solution, acknowledging its competitiveness and direct emission-free benefits for applications with no easy alternatives.
