We aim to develop the most comprehensive integrated energy system model for New Zealand. It will be open-source and adaptable for use in future studies. We will do this by building on the energy system planning tool REMix from our partners at the German Aerospace Center and other approaches for forecasting transport demand and detecting potential applications of hydrogen.

We will be able to answer the following pressing questions related to the energy transformation:

• Can green hydrogen help achieve zero-carbon transport, both in and outside cities?
• Can green hydrogen in urban systems help to fulfil net-zero carbon goals? And how does hydrogen help industries, including the primary sector?
• How does green hydrogen aid the integration of renewables? And what are the optimal levels of hydrogen deployment for minimizing spillage?
• How can the uncertainties from extreme droughts and future hydrogen costs be addressed in planning tools?
• Can hydrogen provide competitive long-term storage (like a 鈥渘ational battery鈥�)?
• What are the environmental impacts and benefits of hydrogen, contextualized in an integrated energy system?
• What are the opportunities that green hydrogen opens to our local communities? Can it improve energy poverty and equity?
• What is New Zealand鈥檚 potential role within the hydrogen exporting triangle (Australia, Chile, North America)? And what hydrogen concepts should New Zealand envision? For example, off-shore hydrogen hubs with pipelines and ship transport? Production close to consumers? Hydrology颅dependent imports and exports?
• Can New Zealand become energy-independent by using hydrogen technologies? And can we power the Pacific Islands?

We will leverage the existing hydrogen roadmap and the expertise of an international, multidisciplinary team of energy, transport, electricity, and environmental experts to assess the role, advantages, and benefits of future hydrogen use in Aotearoa.

We will disseminate our work with the government, industry and Maori partners, and other scientists through workshops, conferences, and publications.
