The potential contribution of hydrogen as a clean energy carrier to industrial decarbonization is outlined in this concise knowledge poster. It explains why hydrogen must be produced through dedicated processes and compares the main hydrogen production pathways through the commonly used color code. The poster then focuses on green hydrogen, presenting the main electrolysis technologies: alkaline, PEM, AEM, and solid oxide electrolysis. It compares their maturity, advantages, and limitations. It also summarizes key policy recommendations to enable hydrogen scale-up, including stronger demand signals, financing instruments, and infrastructure build-out. Lastly, the poster highlights hydrogen technologies and companies across the TfNZ ecosystem.
Our policy recommendations to enable hydrogen scale-up:
GHG-reduction quotas in transport (especially aviation and shipping), a clear decarbonisation pathway for power plants, and a green-gas quota can provide reliable demand signals and unlock private investment.
Public guarantees, long-term offtake guarantees, and Carbon Contracts for Difference (CCfDs) can be effective to secure predictable revenue and attract large-scale finance.
Renewable energy build-out, hydrogen transport and storage networks, and cross-sector integration need to be supported to avoid bottlenecks and enable system-wide deployment.
